Problems solved by technology

[0002] In related technologies, image sensors can be used for gap detection, but the cost is relatively high, and the post-processing of graphics is troublesome
In addition, the gap detection can also be carried out through the relatively arranged laser emitting tube and laser receiving tube (referred to as the laser pair tube), and the cost is relatively low. However, since the distance between the laser emitting tube and the laser receiving tube is generally greater than 2 cm, the accuracy of the detection result is not high.

Abstract

The invention provides a gap detection method and device. In the application, the gap detection method is applied to the gap detection device, the gap detection device comprises N photosensitive chips, the N photosensitive chips are arranged along a first direction, N is an integer greater than 1, and the method comprises the following steps: acquiring N first light intensity values acquired by the N photosensitive chips; comparing the N first light intensity values to acquire M maximum first light intensity values in the N first light intensity values; wherein M is a positive integer; determining first position information of the M photosensitive chips which acquire the maximum M first light intensity values; and acquiring second position information of the gap according to the first position information of the M photosensitive chips. According to the embodiment of the invention, the method can improve the precision of gap detection, and can reduce the cost of gap detection.

Description

technical field [0001] The present application relates to the technical field of logistics detection, and in particular to a method and device for gap detection. Background technique [0002] In the related art, an image sensor can be used for gap detection, but the manufacturing cost is relatively high, and the later image processing is cumbersome. In addition, the gap detection can also be carried out through the relatively arranged laser emitting tube and laser receiving tube (referred to as laser pair tube), the cost is relatively low, but since the distance between the laser emitting tube and the laser receiving tube is generally greater than 2 cm, the accuracy of the detection result is not high. Contents of the invention [0003] In view of this, the embodiments of the present application provide a gap detection method and device, which can improve the accuracy of gap detection and reduce the cost of gap detection. [0004] An embodiment of the present application ...
