Description

technical field [0001] The invention relates to the field of robots, in particular to a machine vision automatic ball picking robot for tennis. Background technique [0002] Tennis is a popular ball game all over the world. Its exercise volume can be adjusted flexibly. It is a good aerobic exercise, and it can also exercise thinking and reaction speed. Therefore, more and more people are playing tennis now. When practicing tennis, many balls will be scattered on the court, and every time a ball is played, a ball will be scattered in a different place, so picking up the ball has become a cumbersome problem. [0003] There are mainly the following ways to pick up the ball in tennis: [0004] 1. Picking up the ball manually, this is a more commonly used way of picking up the ball. This way of picking up the ball is manpower-intensive. At least one person is arranged for each court to pick up the ball. In this way, the workload of the ball-picking personnel is relatively large ...

Problems solved by technology

[0004] 1. Picking up the ball manually, this is a more commonly used way of picking up the ball. This way of picking up the ball is manpower-intensive. At least one person is arranged for each court to pick up the ball. In this way, the workload of the ball-picking personnel is relatively large and consumes more energy.

[0005] 2. Artificially added ball picking tools, including ball picking carts and ball picking devices, etc., such as patent number 200320128160.1, the patent name is tennis ball picking basket that is easy to move and pick up balls; patent number is 201620407372.0, and the patent name is a portable tube Shaped tennis ball picker; the patent number is 201520503738.X, and the patent name is a cylindrical tennis ball picker, etc. Although this type of ball picker improves efficiency compared with completely manual ball pickers, it still has to be manually participated, and it is also Arrange at least one person to pick up the ball in each court, such a person also has a large manpower investment

[0006] 3. Autonomous tennis ball picking robot, such as patent number 200810183233.4, the patent name is autonomous ball picking robot; Low, poor intelligence; or it is necessary to establish a complex monitoring system for the entire training ground and cooperate with ball picking, including host computer, ball picking system, data acquisition system, etc. This kind of ball picking method itself has high cost and has limitations on the field nature, can only be used in a fixed field

[0007] Therefore, in view of the current low efficiency of picking up tennis balls, high labor costs, and the lack of existing ball picking tools, it is necessary to design a ball picking tool that is easy to use, low in cost, high in intelligence, and suitable for various tennis courts.
