High-pole embroidery ball detecting and counting system based on machine vision

Abstract

The invention relates to the technical field of counting, in particular to a high-pole embroidery ball detection counting system based on machine vision, which comprises a ball throwing ring, a rod body, an image acquisition module, an image preprocessing module, a to-be-detected area acquisition module, a target detection counting module and a counting display module. The image acquisition moduleis used for shooting the ball throwing ring and embroidery balls. The image preprocessing module is used for preprocessing images shot by the image acquisition module. The to-be-detected area acquisition module is used for acquiring a spherical ring contour and manufacturing a spherical ring contour area mask. The target detection counting module is used for counting the score of the embroidery ball by utilizing a Gaussian mixture model and a pixel coordinate system. The counting display module is used for displaying counting conditions. The influence of illumination intensity can be effectively prevented, and a clear pitching ring contour can be obtained for accurate counting.

Description

technical field [0001] The invention relates to the technical field of counting, in particular to a machine vision-based tall hydrangea detection and counting system. Background technique [0002] Hydrangea throwing with high poles is a sports event for ethnic minorities in Guangxi. The hydrangea is stitched with silk cloth filled with sand, 5-6cm in diameter, and tied with a 90cm string. The high pole is composed of three parts: the pitching outer ring, the pitching inner ring and the pitching rod, all of which are made of hollow steel pipes. The height of the entire high pole is 10m. The outer ring of pitching is 10cm wide, and the radius of the inner ring of pitching is 50cm. The game is mainly through throwing the ball to the inner circle of the pitch at a fixed field 7m away from both sides of the pitching pole within the specified time, and the outcome of the game is determined by the number of goals scored. Combining computer vision technology with sports events ca...

However, when the above method is used to segment the pitching ring image, due to the partial consistency of the background color and the foreground color pixels and the influence of light, the segmentation result is partially redundant and incomplete, and due to the influence of light, the segmentation result is different from the pitching outer circle of the original image. big contrast loss
