AI Technical Summary
Technical Problem
In the prior art, the gap between the door rubber strips is small and the detection method is large, resulting in low detection accuracy of the rubber strip gap.
Method used
By detecting, segmenting and interpolation of the image to be detected, the target image containing the gap of the target rubber strip is accurately obtained, and the edge contour lines on both sides of the gap of the target rubber strip are determined through edge detection. Finally, the distance value is calculated by uniform sampling to determine whether the gap is qualified.
Benefits of technology
Improve the accuracy of gap detection, reduce errors, ensure accurate detection of the gap between the glue strips, and avoid abnormalities caused by too large or too small gaps.

Abstract
The invention discloses a gap detection method and device, computer equipment and a storage medium, relates to the technical field of machine vision gap measurement, and solves the problem of low precision of rubber strip gap detection caused by large error of a rubber strip gap detection method due to small vehicle door rubber strip gap in related technologies. The method comprises the following steps: acquiring a to-be-detected image, and performing target detection on the to-be-detected image to obtain a target bounding box containing a target adhesive tape gap; segmenting the to-be-detected image based on the target bounding box to obtain a segmented to-be-detected image, and interpolating the segmented to-be-detected image to obtain a target image; performing edge detection on the target image to obtain edge contours on two sides of the target adhesive tape gap; uniformly sampling edge contours on two sides of the target adhesive tape gap to obtain N pairs of sampling points;
