Table tennis ball picking device and automatic photographing device based on same

Abstract

The invention discloses a table tennis ball picking device, and the device comprises a rack, a displacement mechanism, ball picking mechanisms, a ball collection mechanism, a control mechanism, a photographing mechanism, and a power mechanism. The rack is used for installing all parts. The displacement mechanism is installed at the bottom of the rack, and comprises a first drive motor and a longitudinal traveling wheel in transmission connection with the first drive motor. The displacement mechanism also comprises a second drive motor and a lateral traveling wheel in transmission connection with the second drive motor. The device is provided with two sets of ball picking mechanisms, and the two ball picking mechanisms are respectively disposed at the front and rear ends of the rack in the movement direction of the longitudinal traveling wheel. The ball collection mechanism comprises a ball feeding channel installed at a downstream side of a ball feeding plate, a screw blade disposed in the ball feeding channel, and ball collection frames which are located at two ends of the ball feeding channel. The invention also provides an automatic photographing device based on the above device. The path of the table tennis ball picking device is simplified, and the table tennis ball picking device achieves many functions.

Description

technical field [0001] The invention relates to a table tennis ball picking device and an automatic shooting device based on the device. Background technique [0002] The emergence of intelligent table tennis ball machines, the use of computers to analyze the trajectory of table tennis, etc., all of these series of appearances have enabled table tennis players to get better exercise and achieve better results. The use of a professional table tennis ball picker can reduce the burden of training personnel to recover table tennis balls, reduce invalid training time during training, and improve the training efficiency of athletes. [0003] There are also many types of table tennis ball pickers at present, such as manual ball pickers and smart ball pickers, and smart ball pickers can collect table tennis balls while athletes are playing without wasting time. However, one of the existing intelligent ball picking devices is a remote control type, which needs to be remotely control...

AI Technical Summary

Problems solved by technology

However, one of the existing smart ball picking devices is a remote control type, which requires human remote control and still requires human intervention. The other is to use a camera to obtain the position of the table tennis ball and then pick it up. However, the recognition ability of the camera is limited. not efficient

Moreover, the price of the existing intelligent ball picking device is relatively high, and it can only realize the ball picking function, and it loses its value when no training is performed, resulting in low cost performance
