Problems solved by technology
The traditional detection method is to rely on non-special tools and artificial experience. Although this method seems feasible, it takes too much time, the steps are cumbersome and the accuracy is low. At the same time, it lacks sufficient scientificity and rigor
[0003] At present, there are some devices for testing the quality or specifications of table tennis balls, which mainly detect the quality, diameter, bounce and eccentricity of table tennis balls. , and the vernier caliper is still used to detect the diameter and the center of the sphere, and the detection of data errors, especially the detection of the center of the sphere is more difficult

Embodiment Construction
[0029] For further understanding of the present invention, set forth in detail below in conjunction with accompanying drawing and embodiment:
[0030] Such as Figure 1 to Figure 7 Shown: the table tennis standard detection device, including: quality detection module 1, diameter and center degree detection module 2 and bounce detection module 3; the diameter and center degree detection module 2 is fixed under one side of the quality detection module 1 , a bounce detection module 3 is fixed below the diameter and center of sphere detection module 2;
[0031] The diameter and the center of sphere detection module 2 include: an image acquisition module 21, a slide rail 22, a control center 23 and a mobile support 24, the slide rail 22 is inclined from top to bottom, and the two tracks of the slide rail 22 The distance between the inner sides is 26-30mm, and the distance between the outer sides of the two rails is not more than 38mm. A mobile bracket 24 that can slide relative to...

The invention, which belongs to the sports apparatus field, provides a ping pong specification detecting device having characteristics of integration of main ping pong detection items and convenient and rapid detection mode. The ping pong specification detecting device comprises a mass detection module, a diameter and spherical degree detection module and a bounce detection module. The diameter and spherical degree detection module is fixed below one side of the mass detection module; and the bounce detection module is fixed below the diameter and spherical degree detection module. The diameter and spherical degree detection module includes an image acquisition module, a slide rail, a control center and a moving bracket; the slide rail is arranged obliquely from top to bottom; the moving bracket that can slide relative to the slide rail is arranged above the slide rail; a baffle is fixed on the moving bracket; the image acquisition module is disposed on the moving bracket and the center of the lens of the image acquisition module is arranged downwardly; and the control center is fixed on the moving bracket and is used for controlling the moving speed of the moving bracket.
Description
technical field [0001] The invention relates to a table tennis standard detection device, which belongs to the field of sports equipment. Background technique [0002] It is clearly stipulated in the rules of table tennis that the ball of table tennis is a spherical body with a diameter of 40mm and a table tennis ball weighing 2.7 grams. The table tennis table can be made of any material and should have consistent elasticity. When the high place falls to the table, the bounce height should be about 23 cm. At present, the balls and tables used in both international competitions and domestic competitions at all levels are designated for the competition, and the detection of ball specifications for table tennis competitions before the competition is blank, especially in the basic training process of various table tennis clubs. There is no necessary testing link for training balls. The traditional detection method is to use non-special tools and artificial experience method. A...
