Abstract

A shape recognition method and device in an image, wherein the recognition method includes recognition of a shape to be recognized, and selecting the shape to be recognized from candidate shapes, specifically including the steps of: acquiring an original image (S1); based on the shape corresponding to the shape to be recognized Hough transform formula, perform Hough transform on the original image to obtain the function image (S2); calculate the modulus of the first-order gradient of each point in the function image to obtain the gradient image (S3); determine the gray value of each point in the gradient image The local maximum point corresponding to the local maximum point is obtained (S4); based on the Hough transform formula corresponding to the shape to be recognized, the local maximum point is subjected to Hough inverse transform to obtain the candidate shape corresponding to the local maximum point, and This is taken as the recognition result of the shape to be recognized (S5). This recognition method has high accuracy for the recognition of the shape in the image.

Description

technical field [0001] The invention relates to the field of image processing, in particular to a shape recognition method, device, equipment and computer storage medium in an image. Background technique [0002] Image processing and recognition is an important field of artificial intelligence. It belongs to advanced computer vision technology. It has been widely used in the matching of maps and terrains, the recognition of fingerprints and seals, the restoration of historical text and picture documents, and various industrial and detection robots. and other fields. [0003] In the modern semiconductor industry, various technologies have been converted to intelligence. Among them, the vision system based on the image recognition algorithm in the equipment is the key technology in the industry. Workpieces, to perform different operations on workpieces of different shapes, and workpieces generally have key features of geometric shapes such as straight lines and circles, so th...
