Abstract

The embodiments of the invention disclose a sensor calibration method. The sensor calibration method is applied to the communication technical field. The method includes the following steps that: theposture parameter of a mobile terminal is acquired; a capacitance change value measured by a capacitive proximity sensor is obtained if it is confirmed that the mobile terminal is in a horizontal state according to the posture parameter; and if the capacitance change value is greater than a preset numerical value, a capacitance value currently measured by the capacitive proximity sensor is used asthe reference capacitance value of the capacitive proximity sensor. The embodiments of the invention further disclose an electronic device and a computer readable storage medium. With the electronicdevice and the computer readable storage medium of the invention adopted, the accuracy of the judgment of the approaching of a face to the screen of the mobile terminal by the capacitive proximity sensor can be increased.

Description

technical field [0001] The invention belongs to the technical field of communication, and in particular relates to a sensor calibration method, an electronic device and a computer-readable storage medium. Background technique [0002] With the popularity of full screens, there is almost no space for proximity infrared sensors on the front of mobile phones, so capacitive proximity sensors such as SAR (Specific Absorption Rate) sensors will be used to replace proximity infrared sensors. Capacitive proximity sensors can be placed near the antenna area of ​​a mobile phone to detect whether a human face is approaching by sensing capacitance. [0003] However, the capacitive proximity sensor may detect errors. When the mobile phone screen is close to an object that is not a human face, capacitance will be generated. The capacitive proximity sensor will be mistakenly identified as a face approaching state due to the detected capacitance value, resulting in abnormal recognition and ...
