Detailed Description
For the purpose of making the objects, technical solutions and advantages of the present invention more apparent, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings, and it is apparent that the described embodiments are some embodiments of the present invention, not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
The terms first, second and the like in the description and in the claims and in the above-described figures, are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used may be interchanged where appropriate such that the embodiments described herein may be implemented in other sequences than those illustrated or otherwise described herein.
Technical terms related to the present invention are described as follows:
motion sensors are mainly divided into two categories: acceleration sensors and gyro sensors; an acceleration sensor for recognizing the movement of the object by detecting the change of the acceleration of the object; the gyro sensor recognizes the rotation or direction change of the object by detecting the change of the angular momentum of the object.
Acceleration sensor (Accelerometer Sensor): a sensor capable of measuring acceleration of an electronic product is characterized in that the acceleration is obtained through calculation by testing inertia acting force applied to a mass block in the sensor. The acceleration of the electronic product in a three-dimensional space can be detected by the 3-axis acceleration sensor of the consumer electronic product, and the motion information of the consumer electronic product is acquired, so that the motion step counting is realized.
Gyro Sensor (gyroscillope Sensor): a sensor for acquiring rotation and direction information of an object by measuring angular momentum change using a gyro principle. Consumer electronic products are usually 3-axis gyroscopic sensors, so that rotation and direction information of the electronic product in a three-dimensional space can be detected, and the sensor is commonly used for navigation direction recognition, hand rotation operation, head motion tracking and the like. In an implementation form, the 3-axis acceleration sensor and the 3-axis gyro sensor are typically integrated into one IC chip.
Because in the existing design scheme, the application of the motion sensor depends on the original calibration of the electronic product when leaving the factory, the application of the motion sensor cannot be effectively self-checked and self-calibrated due to the influence of physical effects (such as static electricity and electromagnetic influence), environmental factors (such as temperature and humidity), human factors (such as careless drop and sweat/cosmetic pollution) and the like during the use of the electronic product, so that the motion sensor can be restored to a better working state, and the application experience of the electronic device is reduced. Therefore, the following problems occur: for example, the user has run a few kilometers, but the electronic device is still a zero motion step counter; the navigation direction is inaccurate; the speed of the movement is matched and the path is erratic; the VR/AR head movement tracking is not timely and accurate, so that the problems of dizziness and the like caused by mismatching of picture and sound positioning are caused.
Therefore, in order to solve the technical problem that the motion sensor in the prior art does not have the function self-checking and repairing function, the invention provides a motion sensor correcting method, a device, electronic equipment and a storage medium, which can perform the self-checking and repairing on the motion sensor, effectively solve the problem caused by the response speed, the precision and the function reliability in the application process of the motion sensor and improve the user experience of products.
The motion sensor correction method, apparatus, electronic device, and storage medium of the present invention are described below with reference to fig. 1 to 4.
Referring to fig. 1, fig. 1 is a flowchart of a motion sensor calibration method according to an embodiment of the invention. The method for correcting the motion sensor provided by the embodiment of the invention comprises the following steps:
step 110, determining a current state of the motion sensor, wherein the current state comprises a first state and a second state.
Illustratively, the current state of the motion sensor is a state for feeding back whether the user is in motion. The first state comprises a static state in which the motion sensor has abnormal conditions and a real static state in which the motion sensor is normal in function, and the real static state indicates that the user does not move. The second state is a real motion state, and represents that the user is in the real motion state.
Illustratively, the step of determining the current state of the motion sensor includes:
and step 111, reading the data of the motion sensor every preset time.
The preset duration may be customized according to a user, for example, every 10 minutes may be set. The data mainly comprise acceleration data and angular momentum data, but the data can also comprise other physical quantities according to actual application requirements.
For example, the data of the motion sensor may be read periodically by the application processor.
Step 112, comparing whether the currently read data is consistent with the previously read data.
For example, the acceleration data and angular momentum data fed back by the motion sensor currently read may be compared with the acceleration data and angular momentum data previously read for whether there is a change.
And 113, if the motion sensor is consistent, judging that the current state of the motion sensor is a first state.
For example, if the acceleration data and the angular momentum data fed back by the motion sensor read currently are consistent with the acceleration data and the angular momentum data read previously, the motion sensor is judged to be in the first state.
Step 114, if the current state of the motion sensor is inconsistent, it is determined that the current state of the motion sensor is the second state.
For example, if the acceleration data and the angular momentum data fed back by the motion sensor currently read are inconsistent with the acceleration data and the angular momentum data previously read, the current state of the motion sensor is judged to be the second state.
And step 120, if the current state is the first state, controlling the preset vibration system to output first vibration information in a first mode so as to perform function detection on the motion sensor.
By way of example, functional detection refers to detection of the action or use of the motion sensor, e.g. functional detection refers to whether the motion sensor can detect angular velocity data and angular momentum data. Whereas performance detection refers to the detection of the mass of the motion sensor, performance detection refers to how accurate the acceleration data and angular momentum data detected by the motion sensor are, for example.
Illustratively, the preset vibration system is configured to output vibration information for detection by the motion sensor. For example, the preset vibration system may be a system formed by a motor assembly, the motor may cause the electronic device to which the motion sensor is applied to generate a change in acceleration and angular momentum during vibration, and the change in acceleration and angular momentum may be detected by the motion sensor.
Illustratively, the step of controlling the preset vibration system to output the first vibration information in the first mode to functionally detect the motion sensor includes:
and step 121, controlling the preset vibration system to output the first vibration information in a first mode with fixed vibration intensity in a preset time period.
For example, the first vibration information may be output at a vibration acceleration of a fixed vibration intensity of 0.8G for a 30ms duration (i.e., 30ms interval) by the processor controlling the preset vibration system.
And step 122, reading the data of the motion sensor, and comparing whether the currently read data is consistent with the previously read data or not in a preset period.
For example, 3 periods may be set, and whether or not the acceleration data and the angular momentum data of the first period, the second period, and the third period are changed may be compared.
And step 123, if the motion sensor functions are consistent, the motion sensor is reset and restarted if the motion sensor functions are abnormal.
For example, if there is coincidence, which means that the data read every cycle is unchanged, i.e., the motion sensor function detects an abnormality, a reset restart operation of the motion sensor is required. For example, an interrupt control signal is sent by the processor to the motion sensor to control the motion sensor to perform a reset restart operation.
Therefore, the problem that the user moves for a long time, the motion count is still zero or the motion count is seriously deviated is avoided by controlling the motion sensor to reset and restart through interruption.
Step 124, if the motion sensor function detection is not consistent, indicating that the motion sensor function detection is normal.
Illustratively, inconsistencies indicate that the data read every cycle has changed, i.e., the motion sensor function detects normal, when the user is not moving, in a truly stationary state.
And 130, if the current state is the second state, controlling the preset vibration system to output second vibration information in a second mode so as to perform performance detection on the motion sensor.
Illustratively, the step of controlling the preset vibration system to output the second vibration information in the second mode to perform performance detection on the motion sensor includes:
and 131, controlling the preset vibration system to output second vibration information in a second mode with variable vibration intensity and duration.
For example, the first vibration information may be output by controlling the preset vibration system by the processor to gradually change the vibration acceleration of the vibration intensity of 0.3G to the vibration acceleration of 1.2G and then gradually change the vibration acceleration of 1.2G to the vibration acceleration of 0.3G.
The first mode of the present invention is different from the second mode, and the first mode is a vibration mode with a fixed intensity and a fixed duration, and the second mode is a vibration mode with a variable intensity and a variable duration. The first mode is a vibration mode for identifying and judging the first state, and is a relatively simple mode. The second mode is used for identifying and judging the vibration mode of the second state, and the vibration mode provided by the vibration system is required to contain the intensity change and the rhythm speed due to the comparison of the accuracy of data and the calibration of the data of the motion sensor, so that whether the accuracy and the response speed of the motion sensor are normal or not is judged.
And step 132, reading the data of the motion sensor, and comparing whether the deviation between the currently read data and the data originally stored in the system is within a preset range.
And step 133, if the deviation is not within the preset range, which indicates that the performance of the motion sensor is abnormal, controlling the motion sensor to start self-correcting repair operation.
For example, if the deviation is not within the preset range, that is, the deviation between the data of the motion sensor at this time and the data originally stored in the system is relatively large, in order to avoid a large deviation between the data output and the actual occurrence, the motion sensor should be calibrated at this time to obtain accurate data. Because the vibration mode, the intensity and the speed provided by the feedback of the vibration system are all known, the precision and the response speed of the motion sensor can be detected and self-calibrated. Therefore, the problems of user experience caused by data record losing and actual asynchronism and the like due to inaccurate data are avoided.
Step 134, if the deviation is within the preset range, it indicates that the performance of the motion sensor is detected to be normal and the data of the motion sensor is recorded.
In summary, in the electronic device, the motion sensor is an indispensable functional device. In the existing design scheme, the motion sensor is only an interface for feeding back motion information, and in the application process, the precision, the response speed and the reliability of the motion sensor can only be configured by depending on factory parameters. Also because of this, motion sensors often become pain and sink points of the user experience in various types of electronic devices.
The vibration feedback in the electronic equipment design system is adopted as the calibration input of the motion information of the motion sensor, and the function detection, the performance self-checking and the self-calibration can be performed in the static state and the called initial stage of the motion sensor due to the control of the vibration intensity, the initial speed and the vibration waveform of the vibration system, so that the reliability of the motion sensor in practical application and the accuracy of the motion information are improved, and the user experience of the motion sensor related application is effectively improved.
Referring to fig. 2, fig. 2 is a flowchart of a motion sensor calibration method according to another embodiment of the invention. The invention discloses a motion sensor correction method, which comprises the following steps:
step 201, data of a motion sensor is read periodically.
Illustratively, the user may set each 10 minutes to read the motion sensor data. The data includes acceleration data and angular momentum data.
Step 202, judging whether the acceleration data and the angular momentum data fed back by the motion sensor change.
If there is no change, it indicates that the current state of the motion sensor is the first state, i.e. in an abnormal state or in a truly stationary state, and step 203 is performed.
If there is a change, it indicates that the current state of the motion sensor is the second state, i.e. in the real motion state, and step 207 is performed.
In step 203, the vibration system outputs first vibration information in a first mode of fixed intensity and duration.
The first mode of the fixed intensity and the duration is a vibration mode for identifying and judging the first state, and is a relatively simple mode.
Step 204, determining whether the acceleration data and the angular momentum data fed back by the motion sensor change.
If there is a change, indicating that the motion sensor function detection is normal, step 205 is performed.
If there is no change, indicating that the motion sensor function is detecting an abnormality, step 206 is performed.
In step 205, the motion sensor function detects normal, when the user has no motion, and is in a true stationary state.
In step 206, the motion sensor detects an abnormality, and a reset operation is required to be performed on the motion sensor.
In step 207, the current state of the motion sensor is the second state, i.e. the user is in the real motion state, and the motion data of the motion sensor needs to be accurately recorded.
Since the user is in a real motion state at this time, and the motion sensor also detects motion data of the user motion, the function is not problematic, but further detection of the performance of the motion sensor is required to detect how accurate the motion data fed back by the motion sensor is.
The vibration system outputs 208 second vibration information in a second mode of varying intensity and duration.
The second mode of intensity and duration change is a vibration mode for identifying and judging the second state, and the vibration mode provided by the vibration system needs to contain intensity change and rhythm speed due to the comparison of data accuracy and the data calibration of the motion sensor, so that whether the accuracy and the response speed of the motion sensor are normal or not is judged.
Step 209, comparing whether the deviation between the motion data recorded at this time and the originally stored motion data is within a preset range.
The motion data recorded at this time refers to the motion data obtained by detecting the second vibration information output in step 208 by the motion sensor. Since the second mode is a vibration mode provided by the vibration system and is used for detecting the performance of the motion sensor, the accuracy and the response speed of the motion sensor are judged whether to be normal or not by changing the intensity and the rhythm. The invention is not limited to how the intensity and the duration of the second mode are changed, and only the change is required to be satisfied.
If the deviation is within the preset range, the deviation is smaller, and step 210 is performed.
If the deviation is not within the preset range, it indicates that the deviation is larger, step 211 is performed.
In step 210, the performance of the motion sensor detects normal and motion data of the motion sensor is recorded normally.
Step 211, performing self-correction repair operation on the motion sensor when the performance of the motion sensor detects abnormality.
In order to avoid large deviation of motion data output and actual occurrence, the motion sensor should be calibrated at the moment to acquire accurate motion information. Because the vibration mode, the intensity and the speed provided by the vibration system are all known, the precision and the response speed of the motion sensor can be detected and self-calibrated, and thus the problems of user experience caused by inaccurate data recording, asynchronous data recording and the like due to inaccurate motion data are avoided.
The motion sensor correction device provided by the invention is described below, and the motion sensor correction device described below and the motion sensor correction method described above can be referred to correspondingly to each other.
Referring to fig. 3, fig. 3 is a schematic structural diagram of a motion sensor calibration apparatus according to the present invention. The motion sensor correction device provided by the embodiment of the invention is applied to electronic equipment, and comprises a vibration system 310, a motion sensor 320 and a processor 330. Wherein the vibration system 310 includes a power module 311 and a vibration module 312.
Illustratively, the vibration system 310 includes a power module 311 and a vibration module 312, the vibration system 310 for outputting vibration information to be detected by the motion sensor 320. For example, the vibration system 310 may be composed of a vibration motor (Vibrator) and a power management chip (PMIC). The processor 330 is connected to the power module 311 through an SPI interface, and the processor 330 is connected to the motion sensor 320 through an I2C interface or an SPI interface.
Illustratively, the motion sensor 320 is used to detect data that is caused by vibration information or user motion to the action of the electronic device.
Specifically, the motion Sensor generally integrates an acceleration Sensor (Accelerometer Sensor) and a gyro Sensor (gyroscillope Sensor) inside one IC chip. The IC chip is connected and communicated with A Processor (AP) 330 of the electronic equipment through an I2C interface or an SPI interface, changes of physical quantities such as acceleration, angular momentum and the like detected by the motion sensor are fed back to the processor 330, and the processor 330 calculates through a processing algorithm to obtain motion information of the electronic equipment at the moment. Various apks (Android application package, application packages) inside the electronic device can acquire motion information, so that various functions such as motion step counting, navigation direction recognition, gesture detection, head motion tracking and the like are realized. The SPI interface adopted by the embodiment of the invention has the advantage of being capable of being used for transmitting the motion data of the electronic equipment or the application scene with larger data demand.
The processor 330 is connected to the power module 311 and the motion sensor 320, and is configured to determine a current state of the motion sensor 320, where the current state includes a first state and a second state; if the current state is the first state, controlling the vibration system 310 to output first vibration information in a first mode to perform function detection on the motion sensor 320; if the current state is the second state, the vibration system 310 is controlled to output the second vibration information in a second mode to perform performance detection on the motion sensor 320, wherein the first mode is different from the second mode.
Specifically, the processor 330 is connected with the power module 311 through an SPI interface, and is responsible for scheduling the vibration application process of the vibration system 310; the power module 311 provides power supply and vibration initiation, intensity, duration, mode, etc. control for the vibration system 312.
