Problems solved by technology

[0003] However, in daily use, due to various reasons, the terminal will inevitably fall from the user's hand
The drop of the terminal can easily cause damage to the sensor, such as causing the displacement of the sensor patch or auxiliary components, etc.
Obviously, this reduces the sensitivity of the sensor, leading to an increase in the error of the sensor

Abstract

The invention discloses a terminal sensor calibration method and device, wherein the method includes: judging whether the terminal is in a preset motion state; Whether the sensor satisfies the preset calibration condition; if it is detected that the sensor of the terminal satisfies the preset calibration condition, the control terminal calibrates the sensor. Therefore, the present invention can calibrate the sensor on the terminal after the preset motion state of the terminal ends, thereby reducing adverse effects on the sensor caused by the terminal falling, etc., and improving the accuracy and sensitivity of the terminal sensor.

Description

technical field [0001] The invention belongs to the technical field of sensors, and in particular relates to a calibration method and device for a terminal sensor. Background technique [0002] With the continuous upgrading of hardware manufacturing technology, equipment manufacturers have been able to integrate various types of sensors on terminals, such as light sensors, distance sensors, air pressure sensors, and acceleration sensors. With the help of these sensors, the terminal can realize various application functions. For example, when the user is talking, if the distance sensor detects that the user's face is close to the screen of the mobile phone, the terminal will control the screen to enter a sleep state, so as to avoid the screen from being triggered by mistake. [0003] However, in daily use, due to various reasons, the terminal will inevitably fall from the user's hand. Dropping of the terminal can easily cause damage to the sensor, such as causing displacemen...
