A shot counting method based on a shot counting device

Abstract

The invention discloses a shot counting method based on a shot counting device, which is carried out according to the following steps: (1). A computer performs K clustering on all points in the first frame depth image collected by a 3D camera; (2). By For the K clusters in step (1), calculate the farthest distance between all cluster points as the diameter of the basket; (3). Calculate the position coordinates of the center point of the basket and the depth of the center point; (4). Read the next frame of depth image to judge whether there is a ball in the image; if found, compare the x and y coordinates of the center point of the sphere and the depth information h with the center point of the basket, if the center point of the sphere, the basket If the coordinate distance and depth of the center point meet the given threshold, it is judged that the ball has scored; otherwise, it is considered not scored; then go to step (1), re-cluster the image, and reposition the basket. The invention counts shots and displays the number of hits, so as to avoid omission and misrecording of the number of hits when counting shots.

Description

technical field [0001] The invention relates to the field of sporting goods, specifically, a method for capturing 3D pictures in real time and dynamically by a 3D camera, transmitting three-dimensional depth information to a computer through a data line, and the computer counting shots. Background technique [0002] Nowadays, looking at the whole world, the sport of basketball can be said to be everywhere, and it has been deeply rooted in our daily life. Wherein a lot of basketball examinations all relate to the use of shot counting device, but the current shot counting device has occurred omissions, mistakes and other situations, so that some unnecessary troubles and disputes have occurred in the process of the test. [0003] The Chinese patent publication number is CN203227284U, the publication date is 2013.10.09, and the name of the invention is a shooting counting device based on a 3D camera. As for the portable electronic device with the function of displaying the numb...

Problems solved by technology

[0004] In the prior art, the image acquired by the portable electronic device is color information, and the spatial position of the basketball cannot be obtained, which may easily cause omission or misrecording of the number of goals; in addition, it is easy to be destroyed because there is no protection device
