Depth detection device

Abstract

The invention discloses a depth detection device, comprising a carrying console, a photographing module, a storing module, an image receiving module, and a processor. The storing module is used to store the standard depth images of a to-be-detected object photographed by the photographing module in advance; the image receiving module is used to obtain the depth images of the to-be-detected object generated by the photographing module; and the processor is used to compare the obtained depth images of the to-be-detected object with the standard depth images stored in the storing module, and when the depth images of the to-be-detected object are detected to be identical to the standard depth images, then, the to-be-detected object is detected to meet the standards; otherwise, the positions in the depth images of the to-be-detected object which are not consistent with those in the standard depth images are detected as abnormal areas. The depth detection device of the invention detects the positions, the numbers and the depth data of the through holes or the grooves in a detected object to see whether they are up to the scratch or not; and at the same time, the depths of the scrapes or defects on the surface of a detected object can also be detected out so as to perform more accurate and more effective detection to the to-be-detected object.

Description

technical field [0001] The invention relates to the field of detection equipment, in particular to a depth detection equipment. Background technique [0002] Many items in daily life are provided with a certain number of through holes or grooves. After the production and processing of these items are completed, it is generally necessary to check whether the position, number, shape and depth of these through holes or grooves meet the standards. It is necessary to detect whether there are scratches and other defects on the surface of the object to be tested. In the prior art, the planar image of the item to be tested is generally taken by a camera device, and then the through hole or the groove on the surface of the item to be tested is judged to be in compliance with the standard by comparing the planar image of the item to be tested with the image of a standard sample. However, it is only possible to judge whether the position and number of through-holes or grooves are corr...

AI Technical Summary

Problems solved by technology

However, it is only possible to judge whether the position and number of through-holes or grooves are correct through the plane image, but it is difficult to judge whether the through-holes are opened, whether the depth of the grooves meets the standard, and it is also difficult to judge the depth of scratches on the surface of the article. etc., which greatly reduces the detection effect of the product
