Problems solved by technology

Image detection technology mostly uses feature point matching algorithms. The more discriminative the feature points used, the greater the amount of calculation required, which leads to low efficiency of primitive detection and cannot meet the needs of real-time detection.

Abstract

The invention provides a centrosymmetric primitive detection method and device, an electronic device and a readable storage medium, and relates to the technical field of image processing. The method comprises the following steps: firstly, determining target edge pixel points from an image to be detected, and grouping the target edge pixel points according to gradient angles of the target edge pixel points and a preset angle range; wherein each angle range comprises a first angle range and a second angle range, and the difference between the maximum value and the minimum value of the first angle range and the second angle range is 180 degrees; calculating the midpoints of any two target edge pixel points in each group of target edge pixel points, and taking the midpoint with the highest occurrence frequency as the target midpoint; and finally, searching a target edge pixel point pair of which the midpoint is the target midpoint in each group of target edge pixel points, and determiningthe position of the centrosymmetric primitive in the to-be-detected image according to all searched target edge pixel point pairs. Therefore, the positions of the centrosymmetric primitives in the to-be-detected image can be quickly obtained.

Description

technical field [0001] The present application relates to the technical field of image processing, in particular, to a method, device, electronic equipment and readable storage medium for detecting a centrosymmetric graphic element. Background technique [0002] When AR (Augmented Reality, Augmented Reality) effect is required, the real scene must be scanned with a handheld device first, and then the scanned data shall be processed to feed back the corresponding AR effect. In this process, image detection technology is used to analyze the obtained scan data to determine the primitives in the real scene. Image detection technology mostly uses feature point matching algorithms. The more discriminative the feature points used, the greater the amount of calculation required, which leads to low efficiency of primitive detection and cannot meet the needs of real-time detection. Contents of the invention [0003] In view of this, the purpose of this application is to provide a c...
