Embodiment 1
[0020] figure 1 It is a schematic flow chart of a temperature drift compensation method for a gyroscope according to an embodiment of the present invention, see figure 1 , the gyroscope is set in the terminal device, and the temperature drift compensation method of the gyroscope includes:
[0021] Step S101, after the terminal device is started, collect the temperature data of the gyroscope and use the gyroscope to collect corresponding sets of gyroscope data;
[0022] Step S102, judging whether the terminal device is in a static state, and when it is judged that the terminal device is in a static state, according to the corresponding relationship between the temperature stored in the terminal device and the gyroscope data, and using the currently collected gyroscope data , supplement or update the gyroscope data corresponding to the specified temperature in real time and save it;
[0023] Step S103, calculating the calibration value of the supplemented or updated gyroscope ...
Embodiment 2
[0026] figure 2 It is a schematic flow chart of a temperature drift compensation method for a gyroscope according to another embodiment of the present invention, see figure 2 In this embodiment, the flow of the temperature drift compensation method for the gyroscope of the present invention will be described in detail in combination with specific application scenarios.
[0027] The application scenario of this embodiment is: a terminal device (for example, a head-mounted virtual reality VR device) is provided with a gyroscope and an accelerometer, and the user's head posture information can be obtained by fusion calculation based on the data obtained by the gyroscope and the accelerometer , and then control VR to perform corresponding operations according to the user's head posture. In other embodiments of the present invention, the terminal device may also be an intelligent mobile terminal such as a smart phone.
[0028] see figure 2 , the temperature drift compensation...
Embodiment 3
[0087] image 3 It is a structural block diagram of a temperature drift compensation device of a gyroscope according to another embodiment of the present invention, see image 3 , the gyroscope is set in the terminal device, and the temperature drift compensation device 300 of the gyroscope includes:
[0088] The data collection unit 301 is used to collect the temperature data of the gyroscope after the terminal device is started, and use the gyroscope to collect corresponding sets of gyroscope data;
[0089] The data optimization unit 302 is used to determine whether the terminal device is in a static state. When it is determined that the terminal device is in a static state, according to the corresponding relationship between the temperature stored in the terminal device and the gyroscope data, and using the currently collected gyroscope data, real-time Supplement or update the gyroscope data corresponding to the specified temperature and save it;
[0090] The data compens...
