Abstract

The invention discloses a ping-pong ball drop point detection and edge rubbing ball judgment system, and relates to the technical field of judgment systems. A detector and a film pressure sensor are connected with a main controller, the main controller is respectively connected with an image extraction module and an image segmentation module, a storage end of the main controller is connected withan image memory, a data processor is connected with the main controller, a power supply module is respectively connected with a mathematical processor and the main controller, the detector is a binocular vision system, the binocular vision system acquires a motion video of the ping-pong ball, recognizes and positions the ping-pong ball in a three-dimensional space from the motion video by designing a related image processing algorithm, and tracks the motion trail of the ping-pong ball in real time, the film pressure sensor is used for detecting the edge wiping condition of the ping-pong ball,an objective and reliable reference is provided for judgment of an edge wiping ball of a referee, and fairness and justice of a match are guaranteed, meanwhile, falling points and moving tracks of theping-pong ball can be detected, use is convenient and rapid detection is facilitated.

Description

technical field [0001] The invention belongs to the technical field of judging systems, and in particular relates to a table tennis drop point detection and edge ball judging system. Background technique [0002] Table tennis is a popular ball game in the world, including attack, confrontation and defense. Match point group, singles, doubles, mixed doubles etc. several; Table tennis is spherical shape, weighs 2.53-2.70 grams, white or orange, is the new plastics ball of raw material with high molecular polymer. [0003] And existing table tennis realizes judgment by judging system when playing a match, and existing judging system can appear error, or inaccurate phenomenon when judging, causes it to easily occur wrong judgment. Contents of the invention [0004] In order to solve the problem that errors or inaccuracies may occur in the judgment of the existing judgment system, which leads to the problem that it is prone to wrong judgments; the purpose of the present invent...
