Description
Technical Field
The application relates to the field of cameras, in particular to a control system, a control method and a control device of image acquisition equipment.
Background
At present, there are two general methods for heating and outputting an image by an image capturing device (such as a camera, etc.):
the method comprises the steps of firstly, starting heating when the temperature in the image acquisition equipment is smaller than a certain temperature value, heating until the temperature is larger than another temperature value, and resetting a DSP (digital signal Processing) chip to output an image through an external singlechip while stopping heating. If the method is adopted, the DSP chip is reset to output the image when the heating is stopped, so the disadvantages of overlong heating time and slow image output exist.
And secondly, heating when the temperature in the image acquisition equipment is less than a certain temperature value, stopping heating until the temperature is greater than another temperature value, and outputting an image by directly resetting the DSP chip while heating. If the method is adopted, the DSP chip cannot be ensured to be at the proper working temperature immediately within a period of time when the heating is just started, so that the phenomenon that the image output by the DSP chip has abnormal pictures can be caused.
The two methods have certain disadvantages when the image acquisition equipment is used for heating and outputting images, and in the two methods, if the preset temperature value corresponding to the heating starting time and the preset temperature value corresponding to the heating stopping time are relatively close, the voltage values respectively corresponding to the two temperature values in the temperature sensor are relatively close. When the singlechip detects the voltage value corresponding to the temperature value when the temperature sensor stops heating, the image acquisition equipment possibly restarts heating due to detection errors, namely, the risk of heating oscillation phenomenon exists.
In view of the above problems, no effective solution has been proposed.

Example 1
According to an embodiment of the present application, there is provided a control system of an image capturing apparatus, as shown in fig. 1, the control system including: a temperature sensor 101, a controller 102, an image processor 103, and a heater chip 104.
The temperature sensor 101 is used for acquiring an environmental temperature value of the image acquisition equipment in real time; the controller 102 is configured to generate a reset signal when the ambient temperature value is higher than a first preset temperature value, and generate a heating signal after the reset signal is generated if the ambient temperature value is lower than a second preset temperature value, where the first preset temperature value is lower than the second preset temperature value; an image processor 103 for resetting triggered by a reset signal; and the heating chip 104 is used for starting a heating function when receiving a heating signal.
Through the above embodiment of the present application, the reset and heating area of the image acquisition device is controlled, different temperature control points are set for the reset processing and the heating processing of the image acquisition device, after the image acquisition device is powered on, the ambient temperature value of the image acquisition device is acquired in real time, and the heating function and the reset function of the image acquisition device are respectively realized based on the relationship between the acquired ambient temperature value and the reset temperature control point (i.e., the first preset temperature value) and the heated temperature control point (i.e., the second preset temperature value). Through the embodiment, the heating time can be shortened, the image processor can be reset at a higher speed by respectively controlling the resetting and heating of the image acquisition equipment, the aims of efficient heating and successful image output of the image acquisition equipment are fulfilled, the technical problem that the efficiency of the image acquisition equipment is low in the whole process of heating and image output is solved, and the technical effects of improving the heating efficiency of the image acquisition equipment and improving the quality of output images are achieved.
The image capturing device may be a device having functions of image capturing, image processing, image outputting, and the like, such as a video camera, a still camera, a scanner, and the like, and in the present embodiment, may be preferentially understood as a hardware device having the above functions. The ambient temperature value of the image acquisition device may be a temperature value of a space inside a housing of the image acquisition device, and under some special environments and applications, the ambient temperature value of the image acquisition device may be defined as a local device ambient temperature value or other ambient temperature values of the image acquisition device, which is not further described herein.
In the above embodiment, at the functional level, the controller 102 is responsible for determining the sequence of executing programs and giving operation control commands required by the various components of the device when executing instructions. The controller in this embodiment may be a combinational logic controller or a micro-program controller, such as a control unit of an external single chip microcomputer.
In the above embodiment, the image Processor 103 is a device having image processing and output functions in the image capturing apparatus, for example, a DSP (Digital Signal Processor) image Processor, and the condition that the image Processor 103 starts and outputs an image is that a reset Signal output by the controller 102 is received, and the reset Signal is used to start the image Processor 103 to output an image.
In the above embodiment, the image processor 103 outputs the field sync signal after the reset is successful, and if the controller 102 does not receive the field sync signal, the controller 102 generates and sends the reset signal to the image processor 103 every first preset time until the reset of the image processor 103 is successful.
The controller 102 in the above embodiment has a reset detection function, and can realize the function by an external single chip, for example, the image processor 103 outputs a field synchronizing signal, that is, a VD (analog signal in image transmission) pulse signal, after the reset is successful, the external single chip detects the field synchronizing signal through an external interrupt pin, and if the external single chip detects the field synchronizing signal through the external interrupt pin, it determines that the reset of the image processor 103 is successful.
Optionally, if the external single chip microcomputer does not detect the field synchronizing signal through the external interrupt pin, it is determined that the image processor 103 is not successfully reset. In this case, the external singlechip forcibly resets the image processor 103 every first preset time until the image processor 103 is successfully reset. The first preset time may be set manually, for example, the first preset time may be set to 10 seconds. The external singlechip carries out forced reset on the image processor 103 every 10 seconds until the reset of the image processor 103 is successful. The success rate of the duplicate image processor 103 is improved by a forced reset method.
Alternatively, the controller 102 outputs a reset signal through a reset pin, and a field sync signal output by the image processor 103 is input to the controller 102 through an interrupt pin of the controller 102. The reset signal in the above embodiment is used to pull up the level of the reset pin after the low level pulse. For example, the reset signal is used to pull up the level of the reset pin after a low level pulse having a period greater than 200 ms.
In the above embodiment, the controller 102 starts timing after sending the generated heating signal to the heating chip 104, and obtains the heating time of the heating chip 104; when the heating time reaches a second preset time, the controller 102 acquires an environmental temperature value acquired by the temperature sensor 101; if the ambient temperature value is lower than the second preset temperature value and the controller 102 does not receive the field synchronization signal, the controller 102 generates a reset signal and sends the reset signal to the image processor 103.
Alternatively, the process of starting timing when the heating chip 104 starts the heating function may be completed by a timing device having the functions of calibrating time and timing in the image capturing apparatus. If the second preset time is 30 minutes and the second preset temperature value is-10 degrees, when the heating time reaches 30 minutes, if the ambient temperature of the image acquisition device, which is acquired by the temperature sensor 101 in real time, is still lower than-10 degrees and the external single chip microcomputer does not detect a field synchronization signal at the same time, the controller 102 forcibly resets the image processor 103 by generating a reset signal and sending the reset signal to the image processor 103. The second preset time and the second preset temperature value in this embodiment may be set or adjusted appropriately by considering factors such as a heating property, a hardware property, a service life, and an environment of the image capturing device. The method further improves the success rate of the reset image processor 103 on the basis of the reset method.
In the above embodiment, after sending the generated heating signal to the heating chip 104, the controller 102 obtains the ambient temperature value collected by the temperature sensor 101; if the ambient temperature value is higher than the second preset temperature value, the controller 102 generates a stop signal and sends the stop signal to the heating chip 104; the heater chip 104 stops the heating function when receiving the stop signal.
Optionally, if the second preset temperature value is-10 degrees, at a certain time after the heating chip 104 starts the heating function, the temperature sensor 101 acquires in real time that the ambient temperature value of the image capturing device is higher than-10 degrees, the controller 102 generates a stop signal based on the detection result and outputs the stop signal to the heating chip 104, and the heating chip 104 receives the stop signal and stops heating the image capturing device by reading a control command of the stop signal.
In the above embodiment, after sending the stop signal to the heating chip 104, the controller 102 obtains the ambient temperature value collected by the temperature sensor 101; if the ambient temperature value is lower than a third preset temperature value, the controller 102 generates a reheating signal and sends the reheating signal to the heating chip 104; when the heating chip 104 receives the reheating signal, the heating function is restarted. Optionally, if the third preset temperature value is-30 degrees, at a certain time after the heating chip 104 receives the stop signal and stops heating through a control command for reading the stop signal, if the temperature sensor 101 acquires in real time that the ambient temperature value of the image capturing device is lower than-30 degrees, the controller 102 generates a reheating signal based on the detection result and outputs the reheating signal to the heating chip 104, and the heating chip 104 receives the reheating signal and heats the image capturing device again through a control command for reading the reheating signal. The method realizes real-time monitoring of the environmental temperature of the image acquisition equipment, and heats the image acquisition equipment according to the monitoring result, and the reheating method is combined with the method for stopping heating, so that the reheating can be used for repeatedly heating the image acquisition equipment when the temperature of the image acquisition equipment changes rapidly and reaches the heating condition, normal use and automatic heating of the image acquisition equipment are realized, and particularly, the image acquisition equipment can be prevented from being used or having high failure rate under extremely cold conditions in low-temperature outdoor activities such as extremely exploration and mountain climbing. Therefore, the heating method greatly improves the heating efficiency of the image acquisition equipment.
In the above embodiment, after sending the reheating signal to the heating chip 104, the controller 102 obtains the ambient temperature value collected by the temperature sensor 101; if the ambient temperature value is higher than the second preset temperature value, the controller 102 generates a stop signal and sends the stop signal to the heating chip 104; when the heating chip 104 receives the stop signal, the heating function is stopped, wherein the difference between the second preset temperature value and the third preset temperature value is greater than the preset threshold value.
Optionally, if the second preset temperature value is-10 degrees, the third preset temperature value is-30 degrees, and the preset threshold value is 15 degrees, after the heating chip 104 restarts the heating function, if the ambient temperature value acquired by the temperature sensor 101 in real time by the image acquisition device is higher than-10 degrees, the controller 102 generates a stop signal based on the detection result and outputs the stop signal to the heating chip 104. In this process, it is necessary to ensure that the absolute value of the difference between the second preset temperature value and the third preset temperature value is greater than the preset threshold value by 15 degrees, that is, by setting the second preset temperature value, the third preset temperature value and the numerical value and the correlation of the preset threshold value, the heating oscillation phenomenon caused by the too small temperature difference of the heating temperature points is avoided, the temperature difference between the two heating temperature points is enlarged in the embodiment, the stop signal is generated by the controller 102 based on the enlarged temperature difference and the detection result of the temperature sensor, and the occurrence of the heating oscillation phenomenon is effectively avoided.
Optionally, the controller outputs a heating signal and/or a re-heating signal through the heating pin.

Alternatively, at the functional level, the controller is responsible for determining the sequence of executing programs and giving operation control commands required by the various components of the device when executing instructions. The controller in this embodiment may be a combinational logic controller or a micro-program controller, such as a control unit of an external single chip microcomputer.
Optionally, the image Processor is a device having image processing and output functions in the image capturing apparatus, for example, a DSP (Digital Signal Processor) image Processor, and the condition for starting and outputting the image is that a reset Signal output by the controller is received, and the reset Signal is used for starting the image Processor to output the image.
Optionally, the ambient temperature value acquired by the temperature sensor in real time by the image acquisition device is-20 degrees, and the first preset temperature value is-30 degrees, the controller generates a reset signal and outputs the reset signal to the image processor through a numerical value relationship between the ambient temperature value of the image acquisition device and the first preset temperature value, that is, when the ambient temperature value of the image acquisition device is higher than the first preset temperature value, wherein the reset signal is used for starting the image processor to output an image.

Optionally, after the heating chip stops the heating function, if the ambient temperature value is lower than a third preset temperature value, a reheating signal is generated and output to the heating chip, wherein the reheating signal is used for restarting the heating function. Optionally, if the third preset temperature value is-30 degrees, at a certain time after the heating chip receives the stop signal and stops heating by reading the control command of the stop signal, if the temperature sensor collects the ambient temperature value of the image capturing device in real time to be lower than-30 degrees, the controller generates a reheating signal based on the detection result and outputs the reheating signal to the heating chip, and the heating chip receives the reheating signal and heats the image capturing device again by reading the control command of the reheating signal. The method realizes real-time monitoring of the environmental temperature of the image acquisition equipment, and heats the image acquisition equipment according to the monitoring result, and the reheating method is combined with the method for stopping heating, so that the reheating can be used for repeatedly heating the image acquisition equipment when the temperature of the image acquisition equipment changes rapidly and reaches the heating condition, normal use and automatic heating of the image acquisition equipment are realized, and particularly, the image acquisition equipment can be prevented from being used or having high failure rate under extremely cold conditions in low-temperature outdoor activities such as extremely exploration and mountain climbing. Therefore, the heating method greatly improves the heating efficiency of the image acquisition equipment.
Optionally, after the heating chip restarts the heating function, if the ambient temperature value is higher than a second preset temperature value, a stop signal is generated and output to the heating chip, wherein a difference between the second preset temperature value and a third preset temperature value is greater than a preset threshold.
Optionally, if the second preset temperature value is-10 degrees, the third preset temperature value is-30 degrees, and the preset threshold value is 15 degrees, after the heating chip restarts the heating function, if the ambient temperature value acquired by the temperature sensor in real time by the image acquisition device is higher than-10 degrees, the controller generates a stop signal based on the detection result and outputs the stop signal to the heating chip. In this process, it is required to ensure that the absolute value of the difference between the second preset temperature value and the third preset temperature value is greater than the preset threshold value by 15 degrees, that is, by setting the second preset temperature value, the third preset temperature value and the numerical value and the correlation of the preset threshold value, the heating oscillation phenomenon caused by the over-small temperature difference of the heating temperature points is avoided, the temperature difference between the two heating temperature points is enlarged in the embodiment, the stop signal is generated by the controller based on the enlarged temperature difference and the detection result of the temperature sensor, and the occurrence of the heating oscillation phenomenon is effectively avoided.
In the above embodiment, the temperature points at which the start heating and the end heating of the "first heating process" are both minus 10 degrees; the temperature points for starting and ending the heating of the second heating process are minus 30 ℃ and minus 10 ℃. The heating oscillation phenomenon can be effectively avoided by separating the temperature point difference between the end heating of the first heating process and the start heating of the second heating process, and separating the temperature point difference between the start and end heating of the second heating process (i.e. the second heating and reheating in the above embodiment).
Optionally, fig. 5 is a schematic flowchart of a control method of a third optional image capturing device according to an embodiment of the present application, and as shown in fig. 5, the method includes the following steps:
in step S501, after power-on, the level of the reset pin is lowered to maintain the reset state, where the reset pin is a reset 2421 pin.
After the image acquisition device is powered on, the external single chip microcomputer (i.e., the controller in the above embodiment) keeps the GPIO pin of the reset 2421 in a low level state, i.e., a reset state, and at this time, the image processor 2421 does not work and does not output images, so that the phenomenon of image abnormality does not occur when the camera is powered on in an environment of-50 degrees.
2421 is a model of an optional image processor in this embodiment.
Step S502, collecting the environmental temperature value in real time.
Specifically, the method can be realized by reading the sampling value of the environmental temperature collected by the temperature sensor in real time.
Step S503, determining whether the ambient temperature value is higher than a first preset temperature value.
The first preset temperature value is a preset reset temperature control point. The first preset temperature value may be-30 degrees.
If the ambient temperature value is higher than the first preset temperature value, executing step S504; if the ambient temperature value is not higher than the first preset temperature value, step S516 is executed.
Step S504, determine whether the reset flag has been set to zero.
The image processor is judged whether to be reset or not by judging whether the reset flag bit is set to zero or not, if the reset flag bit is set to zero, the image processor is judged not to be reset (not in a working state), and if the reset flag bit is not set to zero, the image processor is judged to be reset (already in the working state).
If the image processor is not reset, go to step S505; if the image processor is reset, step S507 is executed.
In step S505, the level of the reset pin is pulled up.
Specifically, the level of the reset pin can be pulled up by the reset signal to reset the image processor to operate normally.
Step S506 is executed to reset the detection flag position to one. Namely, the reset detection flag is set to one.
Specifically, the reset flag may be set to one after the image processor is reset; meanwhile, the interrupt pin is started to enable the interrupt pin of the controller to be in a state to be detected, and the position of the detection mark is reset.
In step S507, it is detected whether the reset detection flag is set. I.e. it is detected whether the reset detect flag is set to one.
If the reset detection flag is set, it indicates that the interrupt pin starts to operate, and starts to detect a field synchronization signal (e.g., VD pulse signal) sent by the image processor, then step S508 is executed; if the reset detection flag is not set, step S516 is executed.
In step S508, it is detected whether a field sync signal is received through the interrupt pin.
If the field sync signal output by the image processor is detected, go to step S509; if the field sync signal of the image processor is not detected, step S510 is executed.
In step S509, the reset detection flag is set to zero, and the heating flag is set to zero.
Step S510, determining whether the reset interval reaches a preset interval. Namely, whether the time difference between the current moment and the last repeated image processor reaches a first preset time or not is judged.
The first preset time may be a time period of a fixed time length, such as 10 seconds.
If the time difference between the current moment and the last repeated image processor reaches a first preset time, executing step S511; if the time difference between the current time and the last time of the duplicate image processor does not reach the first preset time, step S516 is executed.
In step S511, the image processor is reset.
In the above embodiment, after the initialization is completed, when the environment temperature value acquired in real time is greater than minus 30 degrees (when the environment temperature value is less than minus 30 degrees, the DSP is not reset), the level of the GPIO pin of the reset 2421 is pulled high, and the DSP is reset to enable the DSP to normally work to output an image. And a VD pulse signal (field synchronization signal) is output after the DSP is successfully reset, and the signal is connected to an external interrupt GPIO pin of the external singlechip, so that the external singlechip judges 2421 that the reset is successful after detecting the pulse signal. If the pulse signal is not detected by the external singlechip after the reset pin is pulled high, the external singlechip judges that 2421 is not successfully reset, and forcibly resets 2421 once every 10s until the reset is successful.
Optionally, after acquiring the ambient temperature value of the image processor in real time, the embodiment may further include:
in step S512, whether the heating time flag is set is detected. Namely, the heating time flag position is detected to be one.
The heating time flag is set, which indicates that the heating chip starts the heating function.
If the heating time flag is detected to be set, go to step S513; if the heating time flag is not set, the process returns to step S502.
In step S513, a timer is started and the heating time is recorded.
Step S514: and judging whether the heating time reaches a second preset time.
Alternatively, if it is determined that the heating time reaches the second preset time, step S515 is performed; if the heating time is not longer than the second preset time, the process returns to step S503. The second preset time may be 30 minutes.
And step S515, forcibly resetting the image processor, clearing the heating time zone bit and clearing the heating time.
The image processor may be forcibly reset when the warm-up time reaches a certain threshold and the image processor reset is unsuccessful.
It should be noted that, the implementation methods of the reset image processor in step S515 and step S511 may be identical, and both may be used to pull up the level of the reset pin after using the low level pulse through the reset signal. For example, the reset signal is used to pull up the level of the reset pin after a low level pulse having a period greater than 200ms is used.
Through the steps, the DSP process can be forcibly reset according to the heating time: when the temperature is acquired to be less than minus 10 ℃ for the first time in real time after the initialization is finished, heating is started, timing can be started at the same time, and after the timing time reaches 30 minutes, VD signals of which the temperature is still lower than minus 10 ℃ and the DSP is not detected at the same time are acquired in real time (namely the DSP is not successfully reset at the moment judged by the external single chip microcomputer), the external single chip microcomputer can also forcibly reset the DSP.
In step S516, it is determined whether the first heating flag is already set to zero.
If the first heating flag position is already set to zero, indicating that the heating chip has already heated the image acquisition device for the first time, executing step S517; if the first heating flag is not set to zero, it indicates that the heating chip does not heat the image capturing device for the first time, and step S522 is executed.
And step S517, judging whether the environmental temperature value is smaller than a second preset temperature value.
Wherein, the second preset temperature value may be-10 degrees.
If the ambient temperature value is less than the second preset temperature value, go to step S518; if the ambient temperature value is not less than the second preset temperature value, step S520 is executed.
In step S518, it is determined whether the heating function of the heater chip is in an off state.
Optionally, if yes, execute step S519; if not, the process returns to step S502.
In step S519, the heating function of the heating chip is started, and the heating time is marked and recorded. Wherein the heating time is recorded by a timer. After the step is executed, the process returns to the step S502.
In step S520, it is determined whether the heating function of the heating chip is in an on state.
If yes, go to step S521; if not, the process returns to step S502.
And step S521, stopping the heating function, clearing the heating time zone bit at the same time, and setting the first heating zone bit as one.
In step S522, it is determined whether the ambient temperature value is less than a third preset temperature value. The temperature is the ambient temperature of the image acquisition device acquired by the temperature sensor in real time, and the third preset temperature value can be-30 ℃.
If the ambient temperature value is less than the third preset temperature value, step S523 is executed; if the temperature is not less than the third preset temperature value, step S525 is executed.
Step S523, it is determined whether the heating function of the heating chip is in an off state.
Optionally, if yes, step S524 and step S502 are sequentially executed; if not, the process returns to step S502.
In step S524, the heating chip turns on the heating function.
Step S525, determining whether the ambient temperature value is greater than a second preset temperature value. The temperature is an environmental temperature value of the image acquisition equipment acquired by the temperature sensor in real time.
Optionally, if the ambient temperature value is greater than the second preset temperature value, step S526 is executed; if the temperature is not greater than the second preset temperature value, the step S502 is executed again.
In step S526, it is determined whether the heating function of the heater chip is on.
Optionally, if yes, sequentially executing step S527 and step S502; if not, the process returns to step S502.
In step S527, the heating chip stops heating.

After the heating is stopped, due to factors such as the temperature reduction of the external environment and the like, the temperature acquired in real time is lower than minus 30 ℃, the external singlechip controls the heating chip to start heating again, and the heating is stopped until the temperature acquired in real time is higher than minus 10 ℃, wherein the heating process is expressed as a second heating process. If heating is started again, the heating starting temperature value and the heating ending temperature value are the same as the second heating process.
In the above embodiment, after the initialization is completed, the current temperature voltage value is sampled in real time in the program main loop, in order to enable the machine to start the separate control of the "heating temperature control point (heating point)" and the "resetting temperature control point (resetting point)" as soon as possible after being powered on in an environment of 50 ℃ below zero, the two temperature control points are separated, the temperature control point of the resetting DSP is lowered on the premise of ensuring the stability of the DSP, the heating time of the camera is shortened, and the DSP output image is reset at a faster speed; the heating process is divided into two processes, namely a first heating process and a second heating process, so that the heating oscillation phenomenon is prevented; in addition, in order to ensure the reliability of the control chip for resetting the DSP, a soft reset system is designed to ensure the reliability of the DSP resetting.
