The embodiment of the present application discloses an angle sensor calibration method, device, terminal and storage medium, which belong to the field of computer technology. The folding screen includes an angle sensor, which is used to measure the angle of the folding screen terminal when it is folded. The terminal acquires the target Angle, obtain the preset image corresponding to the target angle from the preset image library, shoot the characteristic image, determine the second signal value when the characteristic image matches the preset image, and set the signal value of the angle sensor corresponding to the target angle as the second signal value Two signal values. It can be seen that the present application can store the preset image corresponding to the target angle in advance in the terminal, and when the angle sensor corrects the signal value corresponding to the target angle, the characteristic image is captured, and when the characteristic image matches the preset image, the first The second signal value is used as the signal value of the angle sensor at the target angle, which corrects the angle sensor in the folding screen terminal and improves the durability of the folding screen terminal.
Description
technical field [0001] The embodiments of the present application relate to the field of computer technology, and in particular to a method, device, terminal and storage medium for calibrating an angle sensor. Background technique [0002] With the increasing demand of users for large-size screens, folding screen terminals have also emerged as the times require without affecting the portability of mobile terminals. [0003] In some application scenarios, when a user uses a folding screen terminal, the user switches the terminal between a folded state and an unfolded state by bending the terminal. Because the folding screen terminal can perform different operations at different folding angles. Therefore, the folding screen terminal needs to determine the current folding angle through an angle sensor. [0004] However, as connecting components such as rotating shafts wear out, at the same bending angle, the signal value measured by the angle sensor may have an error with the...
