Near-object sensor calibration method, device and equipment and computer medium

Abstract

The invention discloses a near-object sensor calibration method, device and equipment and a computer medium, and the method comprises the steps: obtaining a target type of a calibration instruction when the calibration instruction is detected; determining to start a plurality of target baffles which are matched with the target type and are used for corresponding distance calibration, wherein the plurality of target baffles are arranged around a near-object sensor and are equidistant from the near-object sensor; according to the plurality of target baffles, carrying out corresponding distance calibration on the near-object sensor to obtain a plurality of calibration values, and comparing the plurality of calibration values with preset calibration value ranges corresponding to the pluralityof target baffle plates to obtain a calibration result of the near-object sensor, wherein the preset calibration value ranges corresponding to the target baffle plates are different. The technical problem that in the prior art, calibration of different near-object sensors is difficult to meet the requirement for uniformity is solved.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a calibration method, device, equipment and computer medium for a near-object sensor. Background technique [0002] At present, it is often necessary to calibrate the near-object sensor (PSensor) of the TOF (Time of Flight) module, so that the near-object sensor can detect obstacles such as baffles within a certain range after leaving the factory. The breathing light or laser light on the sensor lights up for reminders and other functions. [0003] At present, the calibration process of the near-object sensor is mainly as follows: the near-object sensor emits a laser light on the fixed-distance baffle, and the required chart is attached under the fixed-distance baffle (determined reflectivity), and the near-object sensor receives the The laser light reflected by the baffle will read a value correspondingly. If the value is within the specified range, it is determined that...
