Detailed Description
It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
Referring to fig. 1, fig. 1 is a block diagram illustrating a first embodiment of a vehicle environment detection system according to a hardware operating environment according to an embodiment of the present invention.
As shown in fig. 1, the vehicle environment detection system may include: the system comprises a life information detection module 10, a life information confirmation module 20, an information acquisition module 30, an environment information judgment module 40 and an alarm module 50.
Those skilled in the art will appreciate that the configuration shown in FIG. 1 does not constitute a limitation of a vehicle environment sensing system, and may include more or fewer components than shown, or some components in combination, or a different arrangement of components.
An embodiment of the present invention provides a vehicle environment detection system, and referring to fig. 1, fig. 1 is a block diagram illustrating a first embodiment of the vehicle environment detection system according to the present invention.
In this embodiment, the vehicle environment detection system includes a vital information detection module 10, a vital information confirmation module 20, an information acquisition module 30, an environment information determination module 40, and an alarm module 50.
In this embodiment, the life information detecting module 10 is configured to detect whether life information exists in the vehicle through a millimeter radar signal, and obtain a detection result.
The vital information detection module 10 is a module that detects whether or not a life is present in the vehicle. The vital information is characteristic information of a living body, such as a state of movement, heartbeat, and respiration. The vital information detecting module 10 may detect vital sign information in the vital information to determine whether a life exists in the vehicle. The detection result refers to a result obtained after the detection by the life information detection module 10, and the result may be that life information exists in the vehicle or that life information does not exist in the vehicle.
In the concrete implementation, life information detection module 10 can launch millimeter radar signal through the radar feedback signal who receives millimeter radar signal, obtains whether there is the testing result of life in the car through the analysis and processing to radar feedback signal, and in this embodiment, life information detection module 10 can be through the frequency of radar feedback signal whether there is moving object in the car, and then whether there is life information in the definite car. For example, when the frequency of the radar feedback signal is detected to change, it is indicated that an object in the vehicle is moving, and a detection result of life information in the vehicle can be obtained.
The life information confirming module 20 is configured to obtain current image information of the interior of the vehicle, confirm the detection result according to the current image information, and obtain a life information confirming result.
The vital information confirming module 20 is a module for confirming a detection result obtained by the detection of the vital information detecting module 10. The current image information refers to an image at the current time in the vehicle. The vital information confirmation result is a result obtained by confirming the detection result. The life information confirmation result comprises confirmation that life information exists in the vehicle and confirmation that life information does not exist in the vehicle.
In a specific implementation, the life information confirming module 20 may acquire current image information in the vehicle through a multifunctional sensor, and when the current image information is obtained, may identify the current image information through an image identification algorithm, so as to confirm a detection result. Of course, the current image information can be identified in other manners to obtain the result of confirming whether the life information exists in the vehicle. For example, if the life information exists in the detection result, and if it is determined in the life information determination result that the life information does not exist in the vehicle, the detection is performed again, and if it is determined in the life information determination result that the information exists in the vehicle, it is determined that the life information exists in the vehicle, and the subsequent steps are performed.
The information obtaining module 30 is configured to detect the environment in the vehicle and obtain the environment information in the vehicle when the life information confirmation result confirms that the life information exists.
The in-vehicle environment information is environment information such as temperature, humidity, and gas concentration in the vehicle, which enables life to be survived and is comfortable. The information acquisition module 30 is a module for collecting environmental information in the vehicle. The information acquisition module 30 may be a multifunctional sensor or a combination of multiple sensors.
In a specific implementation, when the life information confirmation result confirms that the life information exists, the information obtaining module 30 may collect the environment information inside the vehicle through the multifunctional sensor, so as to obtain the environment information inside the vehicle. For example, the information acquiring module 30 may acquire temperature information, humidity information, and gas concentration information in the vehicle through the multifunctional sensor, so as to obtain environment information in the vehicle, or may acquire temperature information, humidity information, and gas concentration information in the vehicle through a plurality of sensors, respectively, so as to obtain environment information in the vehicle.
The environment information judging module 40 is configured to judge whether the in-vehicle environment information meets a preset environment condition, and obtain an environment judgment result.
It should be noted that the environment information determining module 40 is a module that determines whether the current environment information in the vehicle meets the standard survival condition. The preset environmental condition refers to a preset environmental condition suitable for the long-term life survival. The preset environmental conditions are mainly standard survival conditions obtained after temperature information, humidity information and gas concentration information in the vehicle are set.
In specific implementation, the environmental information determining module 40 compares the collected in-vehicle environmental information with a preset environmental condition, determines the in-vehicle environmental information, and determines whether the current in-vehicle environmental information meets a condition for life survival according to an environmental determination result, so as to determine that life existing in the vehicle is not dangerous. For example, a driver has a rest in a car due to fatigue driving, and the conditions such as oxygen concentration and temperature in the environmental information in the car are in appropriate states, so that the driver having a rest in the car does not have a safety problem, and at the moment, the driver has no warning effect and can be disturbed to have a rest.
And the alarm module 50 is configured to generate alarm information when the environment determination result indicates that the in-vehicle environment information does not meet a preset environment condition.
The alarm module 50 is a module that gives an alarm when there is a safety problem with vital information in the vehicle. The alarm module 50 may control the vehicle to alarm by generating alarm information, or may send the generated alarm information to the mobile terminal to alarm. The alarm information is information for alarming that life information exists in the vehicle and that the life may be dangerous.
In specific implementation, the alarm module 50 generates alarm information to alarm when it is determined that the environment information in the vehicle does not satisfy the preset environment condition, i.e., the life information in the vehicle has a safety problem. For example, information that life exists in the vehicle is generated and sent to a mobile terminal of the vehicle owner, so that the vehicle owner performs emergency operation, or a control instruction is generated, and the vehicle is controlled to perform prompting information such as light or horn and the like to attract attention of people around the vehicle.
The embodiment discloses a vehicle environment detection system, the system includes a life information detection module 10, a life information confirmation module 20, an information acquisition module 30, an environment information judgment module 40 and an alarm module 50, the life information detection module 10 detects whether life information exists in a vehicle through millimeter radar signals, the life information confirmation module 20 confirms a detection result according to current image information, the information acquisition module 30 acquires environment information in the vehicle when the life information exists, the environment information judgment module 40 judges whether the environment information in the vehicle meets preset environment conditions, and the alarm module 50 generates alarm information when the environment information in the vehicle does not meet the preset environment conditions.

Referring to fig. 2, fig. 2 is a block diagram illustrating a second embodiment of the vehicle environment detection system according to the present invention, which is proposed based on the first embodiment of the present invention.
In the second embodiment, the vital information detection module 10 is further configured to send a millimeter radar signal and receive a radar feedback signal of the millimeter radar signal.
It should be noted that the radar feedback signal refers to a reflection signal received after the millimeter radar signal is reflected by an object. In a specific implementation, the life information detecting module 10 may control the radar module to send millimeter radar signals and receive radar feedback signals in a command control manner, and send the radar feedback signals to the life information detecting module 10.
The life information detection module 10 is further configured to preprocess the radar feedback signal and obtain a frequency of the radar feedback signal.
The preprocessing is processing for optimizing the radar feedback signal. The preprocessing can be noise reduction processing, amplification processing and the like which are beneficial to extracting useful signals in the radar feedback signals. In this embodiment, there may be better preprocessing to obtain the frequency of the radar feedback signal. The radar feedback signal frequency refers to a frequency of a signal wave of the radar feedback signal. The frequency of the radar feedback signal varies with the distance between the object and the radar device.
In specific implementation, the life information detection module 10 may filter the received radar feedback signal to implement number reduction of the radar feedback signal, and then may amplify the radar feedback signal after the noise reduction through the amplifier, and extract the frequency of the radar feedback signal from the amplified radar feedback signal.
The life information detecting module 10 is further configured to obtain adjacent radar feedback signal frequencies of adjacent radar feedback signals.
It should be noted that the adjacent radar feedback signals refer to radar feedback signals acquired in the same time period. The adjacent radar feedback signal may be a radar feedback signal that can be acquired in a previous period, or a radar feedback signal that can be acquired in a subsequent period. The adjacent radar feedback signal frequency refers to a signal wave frequency corresponding to the adjacent radar feedback signal. In a specific implementation process, the acquisition may be performed according to a radar feedback signal frequency acquisition mode, which is not described herein.
The life information detecting module 10 is further configured to compare the radar feedback signal frequency with the adjacent radar feedback signal frequency, and obtain a frequency comparison result.
It should be noted that the frequency comparison result refers to a variation result between the frequency of the radar feedback signal and the frequency of the adjacent radar feedback signal. The frequency comparison result comprises the frequency of the radar feedback signal changed and the frequency of the radar feedback signal unchanged.
In a specific implementation, the vital information detection module 10 may compare the frequency of the radar feedback signal with the frequency of an adjacent radar feedback signal to obtain a frequency comparison result.
The life information detecting module 10 is further configured to determine whether life information exists in the vehicle according to the frequency comparison result, and obtain a corresponding detection result.
It should be noted that, in this embodiment, whether a moving object exists in the vehicle is determined according to the frequency comparison result, and thus whether life information exists in the vehicle can be determined. For example, when the frequency comparison result is that the frequency of the radar feedback signal changes, it is determined that a moving object exists in the vehicle, and it is determined that life information exists in the vehicle, otherwise, it is determined that life information does not exist in the vehicle.
In the second embodiment, the vital information confirming module 20 is further configured to obtain current image information of the interior of the vehicle, and identify the current image information through an image identification algorithm to obtain image feature information.
The image feature information is information having identification property included in the current image information. The image characteristic information may reflect information required to be expressed by the current image information as a whole. For example, when the life information in the car is confirmed, the pet information is included in the current image information.
In specific implementation, the noise of the current image information can be reduced through a median filtering algorithm, and the noise-reduced current image information is identified through an image identification algorithm, so that the image characteristic information in the current image information is determined.
The life information confirming module 20 is further configured to extract abnormal image information of the interior of the vehicle from a preset image according to the image feature information.
The preset image refers to a preset image library. The preset image includes a large amount of abnormal image information of the interior of the vehicle. The abnormal image information is image information having life information in the vehicle. For example, the interior of the vehicle has image information such as a human face, a body, four limbs, and a tail of a pet.
In a specific implementation, the vital information confirming module 20 may extract abnormal image information including the image feature information from a preset image through the image feature information. For example, the image feature information is tail information of the pet, and the life information confirming module 20 may extract an abnormal image having a tail of the pet in the preset image.
The life information confirming module 20 is further configured to compare the current image information with the abnormal image information to obtain image similarity information.
Note that the image similarity refers to how much the same portion is between different images. The image similarity is the manifestation of the same degree of images. In a specific implementation process, the vital information confirming module 20 may determine, by using a perceptual hash value algorithm, respective corresponding picture fingerprints according to hash values of the two images for hash values of the current image information and the abnormal image information, and determine image similarity information in the current image information and the abnormal image information by comparing the picture fingerprints.
The life information confirming module 20 is further configured to confirm the detection result according to the image similarity information, and obtain a life information confirming result.
It should be noted that, in this embodiment, when the life information confirming module 20 acquires the image similarity information, the detection result may be confirmed by a specific numerical value of the image similarity information. For example, when the value of the image similarity exceeds ninety percent, the current image information is obtained to be the same as the abnormal image information, namely, the existence of the life information is confirmed in the vehicle.
In the second embodiment, the environmental information determining module 40 is further configured to extract temperature information, humidity information, and gas concentration information in the vehicle from the in-vehicle environmental information.
The temperature information is temperature information of the vehicle interior in the current state. The humidity information is not described in detail. The gas concentration information may refer to the concentration information of oxygen inside the vehicle, or may refer to the concentration information of oxygen and carbon dioxide inside the vehicle, and is not particularly limited herein. In a specific implementation process, the environmental information determining module 40 may filter the acquired environmental information in the vehicle, so as to extract temperature information, humidity information, and gas concentration information in the vehicle.
The environment information determining module 40 is further configured to determine whether the temperature information meets a preset temperature threshold in a preset environment, and obtain a temperature determination result.
It should be noted that the preset temperature threshold refers to a range threshold of the temperature in the preset environment. The preset temperature threshold is a temperature range suitable for life activities. The temperature judgment result is the result of whether the temperature is suitable for life activities. The temperature judgment result comprises a result that the temperature information is suitable for the life activity and a result that the temperature information is not suitable for the life activity. In a specific implementation process, the environmental information determining module 40 may compare the extracted temperature information with a preset temperature threshold, and determine whether the temperature information is within a range of the preset temperature threshold, so as to determine a temperature determination result. For example, if the current temperature information in the vehicle is 20 degrees celsius and the preset temperature threshold is 15 to 25 degrees celsius, the temperature information satisfies the preset temperature threshold, and thus a temperature judgment result that the temperature information in the vehicle satisfies the life activity is obtained.
The environment information determining module 40 is further configured to determine whether the humidity information meets a preset humidity threshold in a preset environment, and obtain a humidity determination result.
The preset humidity threshold refers to a range threshold of humidity in a preset environment. The preset humidity threshold is a humidity range suitable for life activities. The humidity judgment result is a result of whether the humidity is suitable for life activities. The humidity judgment result comprises a result that the humidity information is suitable for the life activity and a result that the humidity information is not suitable for the life activity. In a specific implementation process, the environmental information determining module 40 may compare the extracted humidity information with a preset humidity threshold, and determine whether the humidity information is within a preset humidity threshold range, so as to determine a humidity determination result.
The environment information determining module 40 is further configured to determine whether the gas concentration information meets a preset body concentration information threshold in a preset environment, and obtain a gas concentration determination result.
It should be noted that the preset gas concentration threshold may refer to a range threshold of the oxygen concentration in the environment, and of course, the gas concentration threshold may also be determined by a ratio of the gas in the vehicle, for example, a ratio of the oxygen content to the carbon dioxide content. The gas concentration judgment result is a judgment result of whether the gas concentration is suitable for life activities. In a specific implementation process, the environmental information determining module 40 may compare the gas concentration information in the vehicle with a preset gas concentration, and when the gas concentration information is at a preset gas concentration information threshold, it is determined that the current gas concentration information is suitable for life activities.
The environmental information determining module 40 is further configured to obtain an environmental determination result that the in-vehicle environmental information does not satisfy the preset environmental condition when at least one of the temperature determination result, the humidity determination result, and the gas concentration determination result does not satisfy the preset environmental condition.
It should be noted that at least one item refers to a set of one item and more than one item. In this embodiment, one, two or none of the items do not satisfy the preset environmental condition. In this embodiment, when the temperature determination result, the humidity determination result, and the gas concentration determination result are all required to satisfy the preset environmental condition, it is determined that the current in-vehicle environmental information satisfies the preset environmental condition, that is, the current in-vehicle environmental information is suitable for life activities. In a specific implementation process, the environmental information determination module 40 collates the obtained temperature determination result, humidity determination result, and gas concentration environment result, and when at least one of the results does not satisfy the preset environmental condition, obtains an environmental determination result that the in-vehicle environmental information does not satisfy the preset environmental condition.
In a second embodiment, the system further comprises: an environmental conditioning module 60;
the information obtaining module 30 is further configured to obtain environment information outside the vehicle.
After the warning information is generated, the in-vehicle environment information may be adjusted by opening a window or turning on an in-vehicle adjusting device. If the environment information outside the vehicle needs to be confirmed when the window is opened, the environment information inside the vehicle can be adjusted by opening the window when the environment outside the vehicle is proper. The environment information outside the vehicle refers to environment information outside the vehicle, such as temperature information, weather information, road condition information, and the like. The environment information outside the vehicle may be suitable environment information or unsuitable environment information, such as environment information of rain, high temperature, and the like. In a specific implementation, the information acquisition module 30 may collect the environment information outside the vehicle through a multifunctional sensor outside the vehicle.
The environment information judging module 40 is further configured to judge whether the environment information outside the vehicle meets the preset environment condition, and obtain a judgment result.
The preset environmental condition is an environmental condition suitable for a long life.

Based on the vehicle environment detection system, the invention further provides a vehicle environment detection method, and referring to fig. 3, fig. 3 is a schematic flow chart of a first embodiment of the vehicle environment detection method of the invention.
In this embodiment, the vehicle environment detection method includes the steps of:
step S10: whether life information exists in the vehicle is detected through millimeter radar signals, and a detection result is obtained.
The vital information is characteristic information of a living body, and includes states such as movement, heartbeat, and respiration. The life information detection module can detect the life characteristic information in the life information to determine whether life exists in the vehicle. The detection result is a result obtained after the detection of the life information detection module, and the result may be that life information exists in the vehicle or that life information does not exist in the vehicle.
In the implementation, life information detection module can launch millimeter radar signal through the radar feedback signal who receives millimeter radar signal, obtains whether there is the testing result of life in the car through the analysis and processing to radar feedback signal, and in this embodiment, life information detection module can be through the frequency of radar feedback signal whether there is moving object in the car, and then whether there is life information in the definite car. For example, when the frequency of the radar feedback signal is detected to change, it is indicated that an object in the vehicle is moving, and a detection result of life information in the vehicle can be obtained.
Step S20: and acquiring current image information of the interior of the vehicle, and confirming the detection result according to the current image information to obtain a life information confirmation result.
The vital information confirming module is a module for confirming a detection result obtained by the vital information detecting module. The current image information refers to an image at the current time in the vehicle. The vital information confirmation result is a result obtained by confirming the detection result. The life information confirmation result comprises confirmation that life information exists in the vehicle and confirmation that life information does not exist in the vehicle.
In specific implementation, the life information confirmation module can acquire current image information in the vehicle through the multifunctional sensor, and when the current image information is obtained, the current image information can be identified through an image identification algorithm, so that a detection result is confirmed. Of course, the current image information can be identified in other manners to obtain the result of confirming whether the life information exists in the vehicle. For example, if the life information exists in the detection result, and if it is determined in the life information determination result that the life information does not exist in the vehicle, the detection is performed again, and if it is determined in the life information determination result that the information exists in the vehicle, it is determined that the life information exists in the vehicle, and the subsequent steps are performed.
Step S30: and when the life information confirmation result is that the life information exists, detecting the environment in the vehicle to acquire the environment information in the vehicle.
The in-vehicle environment information is environment information such as temperature, humidity, and gas concentration in the vehicle, which enables life to be survived and is comfortable. The information acquisition module is used for acquiring environment information in the vehicle. The information acquisition module can be a multifunctional sensor or a combination of a plurality of sensors.
In specific implementation, when the life information confirmation result is that the life information exists, the information acquisition module can acquire the environment information in the vehicle through the multifunctional sensor, and further obtain the environment information in the vehicle. For example, the information acquisition module can acquire temperature information, humidity information and gas concentration information in the vehicle through the multifunctional sensor, so as to obtain environment information in the vehicle, and certainly, the information acquisition module can acquire the temperature information, humidity information and gas concentration information in the vehicle through the plurality of sensors, so as to obtain the environment information in the vehicle.
Step S40: and judging whether the environment information in the vehicle meets preset environment conditions or not, and acquiring an environment judgment result.
It should be noted that the environment information determining module is a module that determines whether the current environment information meets the standard survival condition by determining the current environment information in the vehicle. The preset environmental condition refers to a preset environmental condition suitable for the long-term life survival. The preset environmental conditions are mainly standard survival conditions obtained after temperature information, humidity information and gas concentration information in the vehicle are set.
In specific implementation, the environmental information judgment module compares the acquired environmental information in the vehicle with preset environmental conditions, judges the environmental information in the vehicle, and determines whether the current environmental information in the vehicle meets the condition of life survival according to the environmental judgment result so as to determine that the life existing in the vehicle cannot be dangerous. For example, a driver has a rest in a car due to fatigue driving, and the conditions such as oxygen concentration and temperature in the environmental information in the car are in appropriate states, so that the driver having a rest in the car does not have a safety problem, and at the moment, the driver has no warning effect and can be disturbed to have a rest.
Step S50: and generating alarm information when the environment judgment result indicates that the environment information in the vehicle does not meet the preset environment condition.
It should be noted that the alarm module may control the vehicle to alarm by generating the alarm information, or may send the generated alarm information to the mobile terminal to alarm. The alarm information is information for alarming that life information exists in the vehicle and that the life may be dangerous.
In specific implementation, the alarm module generates alarm information to give an alarm when the environment information in the vehicle is determined not to meet the preset environment condition, namely the life information in the vehicle has a safety problem. For example, information that life exists in the vehicle is generated and sent to a mobile terminal of the vehicle owner, so that the vehicle owner performs emergency operation, or a control instruction is generated, and the vehicle is controlled to perform prompting information such as light or horn and the like to attract attention of people around the vehicle.
The embodiment discloses a vehicle environment detection method, which detects whether life information exists in a vehicle through millimeter radar signals, confirms a detection result according to current image information, acquires environment information in the vehicle when the life information exists, judges whether the environment information in the vehicle meets a preset environment condition, and generates alarm information when the environment information in the vehicle does not meet the preset environment condition. Whether this embodiment is reported to the police through the detection to life information in the car, the affirmation of testing result and environmental information's judgement confirmation, more accurate realization report to the police to life detection.
Referring to fig. 4, fig. 4 is a flowchart illustrating a second embodiment of the vehicle environment detection method according to the present invention, and the second embodiment of the vehicle environment detection method according to the present invention is proposed based on the first embodiment illustrated in fig. 3.
In the second embodiment, the step S10 includes:
step S101: sending a millimeter radar signal and receiving a radar feedback signal of the millimeter radar signal.
It should be noted that the radar feedback signal refers to a reflection signal received after the millimeter radar signal is reflected by an object. In specific implementation, the life information detection module can control the radar module to send millimeter radar signals and receive radar feedback signals in a command control mode, and send the radar feedback signals to the life information detection module.
Step S102: and preprocessing the radar feedback signal to obtain the frequency of the radar feedback signal.
The preprocessing is processing for optimizing the radar feedback signal. The preprocessing can be noise reduction processing, amplification processing and the like which are beneficial to extracting useful signals in the radar feedback signals. In this embodiment, there may be better preprocessing to obtain the frequency of the radar feedback signal. The radar feedback signal frequency refers to a frequency of a signal wave of the radar feedback signal. The frequency of the radar feedback signal varies with the distance between the object and the radar device.
In specific implementation, the life information detection module 10 may filter the received radar feedback signal to implement number reduction of the radar feedback signal, and then may amplify the radar feedback signal after the noise reduction through the amplifier, and extract the frequency of the radar feedback signal from the amplified radar feedback signal.
Step S103: and acquiring the adjacent radar feedback signal frequency of the adjacent radar feedback signal.
It should be noted that the adjacent radar feedback signals refer to radar feedback signals acquired in the same time period. The adjacent radar feedback signal may be a radar feedback signal that can be acquired in a previous period, or a radar feedback signal that can be acquired in a subsequent period. The adjacent radar feedback signal frequency refers to a signal wave frequency corresponding to the adjacent radar feedback signal. In a specific implementation process, the acquisition may be performed according to a radar feedback signal frequency acquisition mode, which is not described herein.
Step S104: and comparing the radar feedback signal frequency with the adjacent radar feedback signal frequency to obtain a frequency comparison result.
It should be noted that the frequency comparison result refers to a variation result between the frequency of the radar feedback signal and the frequency of the adjacent radar feedback signal. The frequency comparison result comprises the frequency of the radar feedback signal changed and the frequency of the radar feedback signal unchanged.
In a specific implementation, the vital information detection module 10 may compare the frequency of the radar feedback signal with the frequency of an adjacent radar feedback signal to obtain a frequency comparison result.
Step S105: and determining whether life information exists in the vehicle according to the frequency comparison result, and acquiring a corresponding detection result.
It should be noted that, in this embodiment, whether a moving object exists in the vehicle is determined according to the frequency comparison result, and thus whether life information exists in the vehicle can be determined. For example, when the frequency comparison result is that the frequency of the radar feedback signal changes, it is determined that a moving object exists in the vehicle, and it is determined that life information exists in the vehicle, otherwise, it is determined that life information does not exist in the vehicle.
The step S20 includes:
step S201: the method comprises the steps of obtaining current image information in the vehicle, identifying the current image information through an image identification algorithm, and obtaining image characteristic information.
The image feature information is information having identification property included in the current image information. The image characteristic information may reflect information required to be expressed by the current image information as a whole. For example, when the life information in the car is confirmed, the pet information is included in the current image information.
In specific implementation, the noise of the current image information can be reduced through a median filtering algorithm, and the noise-reduced current image information is identified through an image identification algorithm, so that the image characteristic information in the current image information is determined.
Step S202: and extracting abnormal image information of the interior of the vehicle from a preset image according to the image characteristic information.
The preset image refers to a preset image library. The preset image includes a large amount of abnormal image information of the interior of the vehicle. The abnormal image information is image information having life information in the vehicle. For example, the interior of the vehicle has image information such as a human face, a body, four limbs, and a tail of a pet.
In a specific implementation, the vital information confirming module may extract abnormal image information including the image feature information from a preset image through the image feature information. For example, the image feature information is tail information of the pet, and the life information confirming module may extract an abnormal image having a tail of the pet in the preset image.
Step S203: and comparing the current image information with the abnormal image information to obtain image similarity information.
Note that the image similarity refers to how much the same portion is between different images. The image similarity is the manifestation of the same degree of images. In a specific implementation process, the life information confirming module can determine respective corresponding picture fingerprints according to the hash values of the two images and the hash values of the current image information and the abnormal image information through a perceptual hash value algorithm, and determine image similarity information in the current image information and the abnormal image information through comparison of the picture fingerprints.
Step S204: and confirming the detection result according to the image similarity information to obtain a life information confirmation result.
It should be noted that, in this embodiment, when the image similarity information is acquired, the vital information confirming module may confirm the detection result through a specific numerical value of the image similarity information. For example, when the value of the image similarity exceeds ninety percent, the current image information is obtained to be the same as the abnormal image information, namely, the existence of the life information is confirmed in the vehicle.
The embodiment discloses a vehicle environment detection method, which detects whether life information exists in a vehicle through millimeter radar signals, confirms a detection result according to current image information, acquires environment information in the vehicle when the life information exists, judges whether the environment information in the vehicle meets a preset environment condition, and generates alarm information when the environment information in the vehicle does not meet the preset environment condition. Whether this embodiment is reported to the police through the detection to life information in the car, the affirmation of testing result and environmental information's judgement confirmation, more accurate realization report to the police to life detection.
Referring to fig. 5, fig. 5 is a flowchart illustrating a vehicle environment detection method according to a third embodiment of the present invention, and the third embodiment of the vehicle environment detection method according to the present invention is proposed based on the first embodiment illustrated in fig. 3.
In the third embodiment, the step S40 includes:
the step S40 includes:
step S401: and extracting temperature information, humidity information and gas concentration information in the vehicle from the environment information in the vehicle.
The temperature information is temperature information of the vehicle interior in the current state. The humidity information is not described in detail. The gas concentration information may refer to the concentration information of oxygen inside the vehicle, or may refer to the concentration information of oxygen and carbon dioxide inside the vehicle, and is not particularly limited herein. In a specific implementation process, the environmental information judgment module can filter the acquired environmental information in the vehicle, so as to extract temperature information, humidity information and gas concentration information in the vehicle.
Step S402: and judging whether the temperature information meets a preset temperature threshold value in a preset environment or not, and obtaining a temperature judgment result.
It should be noted that the preset temperature threshold refers to a range threshold of the temperature in the preset environment. The preset temperature threshold is a temperature range suitable for life activities. The temperature judgment result is the result of whether the temperature is suitable for life activities. The temperature judgment result comprises a result that the temperature information is suitable for the life activity and a result that the temperature information is not suitable for the life activity. In a specific implementation process, the environmental information judgment module may compare the extracted temperature information with a preset temperature threshold, and judge whether the temperature information is within a range of the preset temperature threshold, thereby determining a temperature judgment result. For example, if the current temperature information in the vehicle is 20 degrees celsius and the preset temperature threshold is 15 to 25 degrees celsius, the temperature information satisfies the preset temperature threshold, and thus a temperature judgment result that the temperature information in the vehicle satisfies the life activity is obtained.
Step S403: and judging whether the humidity information meets a preset humidity threshold value in a preset environment or not, and obtaining a humidity judgment result.
The preset humidity threshold refers to a range threshold of humidity in a preset environment. The preset humidity threshold is a humidity range suitable for life activities. The humidity judgment result is a result of whether the humidity is suitable for life activities. The humidity judgment result comprises a result that the humidity information is suitable for the life activity and a result that the humidity information is not suitable for the life activity. In a specific implementation process, the environmental information judgment module may compare the extracted humidity information with a preset humidity threshold, and judge whether the humidity information is within a preset humidity threshold range, thereby determining a humidity judgment result.
Step S404: and judging whether the gas concentration information meets a preset body concentration information threshold value in a preset environment or not, and obtaining a gas concentration judgment result.
It should be noted that the preset gas concentration threshold may refer to a range threshold of the oxygen concentration in the environment, and of course, the gas concentration threshold may also be determined by a ratio of the gas in the vehicle, for example, a ratio of the oxygen content to the carbon dioxide content. The gas concentration judgment result is a judgment result of whether the gas concentration is suitable for life activities. In the specific implementation process, the environmental information judgment module can compare the gas concentration information in the vehicle with the preset gas concentration, and when the gas concentration information is at the preset gas concentration information threshold, the current gas concentration information is confirmed to be suitable for life activities.
Step S405: and when at least one of the temperature judgment result, the humidity judgment result and the gas concentration judgment result does not meet the preset environmental condition, acquiring an environmental judgment result that the environmental information in the vehicle does not meet the preset environmental condition.
It should be noted that at least one item refers to a set of one item and more than one item. In this embodiment, one, two or none of the items do not satisfy the preset environmental condition. In this embodiment, when the temperature determination result, the humidity determination result, and the gas concentration determination result are all required to satisfy the preset environmental condition, it is determined that the current in-vehicle environmental information satisfies the preset environmental condition, that is, the current in-vehicle environmental information is suitable for life activities. In a specific implementation process, the environmental information judgment module is used for sorting the obtained temperature judgment result, humidity judgment result and gas concentration environmental result, and when at least one item of the temperature judgment result, the humidity judgment result and the gas concentration environmental result does not meet the preset environmental condition, the environmental judgment result that the environmental information in the vehicle does not meet the preset environmental condition is obtained.
After the step S50, the method further includes:

The environment information outside the vehicle refers to environment information outside the vehicle, such as temperature information, weather information, road condition information, and the like. The environment information outside the vehicle may be suitable environment information or unsuitable environment information, such as environment information of rain, high temperature, and the like. In a specific implementation, the information acquisition module 10 may collect the environment information outside the vehicle through a multifunctional sensor outside the vehicle.
Step S502: and judging whether the environment information outside the vehicle meets the preset environment condition or not, and acquiring a judgment result.
The preset environmental condition is an environmental condition suitable for a long life. In the specific implementation process, the environment information judgment module can judge the environment information outside the vehicle through the preset environment condition and acquire the result of whether the environment information outside the vehicle is suitable for life activities.
Step S503: and controlling the vehicle to open the vehicle window when the judgment result is that the environment information outside the vehicle meets the preset environment condition, otherwise, starting an in-vehicle adjusting device.
The in-vehicle adjustment device is a device for actively adjusting the in-vehicle environment. The in-vehicle conditioning device needs to consume vehicle energy to condition in-vehicle environmental information, such as an in-vehicle air conditioner or the like. In specific implementation, the environment adjusting module can passively adjust the environment information in the vehicle by controlling the vehicle to open the vehicle window when the environment information outside the vehicle meets the preset environment condition. When the environment information outside the vehicle meets the preset environment condition, the environment information inside the vehicle can be actively adjusted by starting the vehicle interior borrowing device.
