Method and device for calibrating distance sensor, and electronic equipment

Abstract

The invention provides a method and device for calibrating a distance sensor and an electronic device, belonging to the terminal device field. The method for calibrating the distance sensor comprises steps of obtaining a calibration strategy, wherein the calibration strategy comprises a calibration condition and at least one sensor identifier corresponding to the calibration condition and each sensor identifier corresponds to a sensor besides a distance sensor in an electronic device, determining whether a target parameter and at least one state parameter satisfy a correction condition, wherein the target parameter is an output value of the distance sensor and the at least one state parameter is an output value of at least one sensor corresponding to at least one sensor identifier in the electronic device, and changing a ground noise value which is configured in the electronic device and corresponds to the distance sensor into a magnitude of the target parameter when the target parameter and at least one state parameter satisfy the correction condition. The method and device for calibrating the distance sensor and the electronic device can eliminate an unfavorable influence brought by a fact that the ground noise value set by a factory is deviated from a practical suitable value, improves reliability of the product and optimizes product performance.

Description

technical field [0001] The present disclosure relates to the field of terminal equipment, and in particular, to a method and device for calibrating a distance sensor, and electronic equipment. Background technique [0002] A sensor is a device that can sense the measured information and convert the sensed information into electrical signals or other required forms of information output according to certain rules. Based on the characteristic that the sensor can perceive changes in the surrounding environment, the terminal device has been able to use it to cooperate with related applications to achieve many practical functions. For example, current smart terminal products are usually equipped with light sensors, distance sensors, and gravity sensors. The light sensors can be used to automatically adjust the screen brightness according to the intensity of ambient light, and automatically adjust the white balance when taking pictures. The distance sensor can Detect whether the ...

Problems solved by technology

However, with the transportation, sale and use of terminal equipment after leaving the factory, the noise floor value suitable for actual use may gradually deviate from the factory set value under the influence of factors such as surface oil pollution, device location change, device aging, etc., which may cause As a result, the actual judgment of the terminal device on the approach event and the far event is far from the design goal. For example, the distance threshold for the mobile phone to automatically turn off the screen becomes too large or too small, which affects the normal use of the user.
