Ball stud size detection method and device, computer equipment and storage medium

Abstract

The invention is applicable to the field of computers, and provides a ball stud size detection method and device, computer equipment and a storage medium. The ball stud size detection method comprisesthe steps of acquiring a first image, preprocessing the first image to obtain a second image, wherein the second image at least comprises a profile diagram of a ball stud; carrying out edge detectionon the contour map, and determining an edge line of the ball stud; and carrying out straight line detection based on Hough transformation on the edge line, determining a straight line part in the edge line, detrmining two end points of the straight line part, adopting the Euclidean distance to measure the distance between the two end points, and obtaining and outputting the straight line size ofthe ball stud. According to the ball stud size detection method provided by the embodiment of the invention, the image of the ball stud is identified and measured through a computer program, the imagenoise is eliminated through image preprocessing, image edge detection and linear detection, and meanwhile, the size is measured through the computer program, so that the speed is high, the efficiencyis high, the product quality is ensured, and the production cost is reduced.

Description

technical field [0001] The invention belongs to the field of computers, and in particular relates to a ball stud size detection method, device, computer equipment and storage medium. Background technique [0002] Ball studs are widely used in independent suspension systems to realize the connection between control arms or thrust rods and other components. important detection parameters. [0003] The existing detection of the size and shape of the ball stud is done manually using a jig, but the jig will be worn during use, resulting in errors in the detection of the ball stud, and the manual detection has low efficiency and low accuracy. The shortcomings of poor quality and limited testing quantity, high labor costs, and workers are prone to fatigue, resulting in missed or false detections, resulting in defective or substandard products flowing into the market, causing reputational and economic losses to businesses. [0004] It can be seen that the detection of the size of ...
