The Application of Mesh Belt and Volleyball Detection Theory in the Tournament Scene Analysis Based on Improved Hough Transform

Abstract

Computer technology and Internet technology development, promote the analysis technology about the physical image and video files. In the actual sports, able to quickly extract effective information by coaches and sports researchers more and more attention, also in volleyball image analysis, demand is also growing. Aiming at the detection of China volleyball scene band and volleyball technical analysis of the status quo, through to the traditional Hough transform in the study of the application of the net belt with volleyball detection and analysis of the flaws of the traditional Hough transform algorithm, and according to the characteristics of the defect, the direction of the algorithm is improved, to explore the improvement of linear transformation and randomized Hough transform circle and adaptive search algorithm combined with the improved Hough transform circle algorithm, analyzed the superiority of the improved algorithm and detection effect, in order to through the analysis of the process and the results of the study for the volleyball scene information detection technology to provide certain theoretical basis. The results showed that the selected randomized Hough transform circle sampling points the way to improve thought is, first of all find out a point on the image, when the points are not isolated, adaptive search proceed along that point, is going to get a line segment, the segment is probably part of the circle, on this line randomly select three points, through calculating and radius, the three points so that it greatly improve the efficiency of the randomized Hough transform circle algorithm.
