Abstract.The identification, positioning and grabbing path planning of table tennis balls are the preconditions for the robot to pick up table tennis balls autonomously. A method of table tennis identification, positioning and grabbing path planning based on monocular vision image processing is proposed. By analyzing the characteristics of table tennis images, a table tennis image segmentation method based on color and contour features is designed. The color and contour features of table tennis images are extracted, and HSV is used for image preprocessing. Image segmentation is processed by … Read more →
