Abstract

The invention discloses a method and apparatus for calibrating a proximity sensor. The method includes the steps of moving a baffle disposed facing a proximity sensor to a position where the distancefrom the proximity sensor is greater than a first distance threshold; obtaining a first distance parameter obtained by the proximity sensor; comparing the obtained first distance parameter with a preset noise floor threshold; in the case where the first distance parameter is smaller than the noise floor threshold, moving the baffle to a second distance threshold, the second distance threshold being smaller than the first distance threshold; obtaining a second distance parameter measured by the proximity sensor; and comparing the obtained second distance parameter with the first distance parameter; and in the case where the second distance parameter is greater than the first distance parameter, determining the proximity sensor as a good product. According to one embodiment of the invention,the calibration speed and accuracy of the proximity sensor are improved.

Description

technical field [0001] The present invention relates to the technical field of sensor detection, and more particularly, to a calibration method and device for a proximity sensor. Background technique [0002] A proximity sensor is a common sensor used in a mobile terminal, and the proximity sensor can be used as a detection and judgment condition for opening or closing an application function. For example, a proximity sensor of a virtual reality headset may be used to control the virtual reality headset to be turned on or off. [0003] During the production process of a mobile terminal provided with a proximity sensor, due to installation factors and factors of the proximity sensor itself, the measurement result of the proximity sensor is inaccurate. Therefore, before the mobile terminal leaves the factory, the proximity sensor needs to be calibrated. The traditional calibration method relies on testers to complete, which will cause problems of low detection efficiency and...
