Abstract

This application discloses a method for prejudging the real-time placement of a badminton ball. The method is applied to a badminton robot, and the badminton robot comprises a camera; the method for prejudging the real-time placement of the badminton ball comprises the steps of obtaining a color image and a depth image of the badminton ball through the camera in real time; calculating first coordinates of the badminton ball in a camera coordinate system according to the color image and the depth image; utilizing the first coordinates and position and posture coordinates to calculate second coordinates of the badminton ball in a world coordinate system, wherein the position and posture coordinates are position and posture coordinates obtained in advance of the badminton robot in the world coordinate system; utilizing the second coordinates and an aerodynamic model of the badminton ball to calculate placement coordinates of the badminton ball in the world coordinate system. According tothe method, by installing the camera on the badminton robot body, the adaptability of the badminton robot to the environment is improved. Accordingly, the invention further discloses a platform and device for prejudging the real-time placement of the badminton ball. The platform and device also have the advantages above.

Description

technical field [0001] The invention relates to the field of image processing, in particular to a method, platform and equipment for real-time impact prediction of badminton. Background technique [0002] With the development of science and technology, badminton robots can replace badminton sparring coaches to complete many sparring sessions, so badminton robot technology has attracted more and more attention and attention, and the prediction of badminton trajectory has become an important factor to measure the performance of badminton robots. Refer to the index, but in the existing technology, the visual judgment system of the badminton robot still needs off-site camera equipment to obtain the movement information of the shuttlecock, and then drive the badminton robot to complete the return action of the shuttlecock. Obviously, when acquiring badminton sports information through off-site camera equipment, it needs to occupy most of the sports field, and this method makes th...
