Wheelchair curling motion state detection and target tracking system

Abstract

The invention provides a wheelchair curling motion state detection and target tracking system, and belongs to the technical field of special devices for sports. The system comprises: a motion state detection device, an image acquisition device and a central control computer which is respectively connected with the two devices, wherein the central control computer comprises a curling motion state resolving module, a curling motion state data display module, a curling motion state data storage module and a curling motion video image processing module. The curling motion video image processing module comprises a curling motion track prediction sub-module, a target tracking sub-module, an ice rink reconstruction sub-module and a curling motion track reproduction sub-module. The influence of shielding on curling target tracking can be effectively prevented, the calculation time is shortened, and a scientific and effective training means and a replaying method are provided for wheelchair curling athletes and coaches in the training and competition process.

Description

technical field [0001] The invention belongs to the technical field of special devices for sports, and relates to a wheelchair curling motion state detection and target tracking system. Background technique [0002] Wheelchair curling is a young sport, which emerged in Europe in the late 1990s and spread to Europe quickly. Due to its own interest and competitiveness, wheelchair curling has quickly won the favor of many sports enthusiasts. . [0003] Wheelchair curling and traditional curling use the same track and the same curling stones. Some of the rules of wheelchair curling also refer to the rules of curling, but there are still obvious differences between the two. In wheelchair curling, athletes must sit in wheelchairs and use push rods to throw pots, and due to the long ice rink, the length between the inner edges of the two end lines of the track is 45.72 meters, and wheelchair curlers are placed on the track. At both ends, during the movement of curling on the ice ...

AI Technical Summary

Problems solved by technology

During the process of brushing the ice, curlers can easily observe the motion state and trajectory of the curling, and adjust the power and rotation of the next throw accordingly. However, it is difficult for wheelchair curlers to directly observe the ice due to the inconvenience of movement. The trajectory and state of the jug on the ice track

[0005] In CN 103157262 B, Xiao Shuming et al. proposed a smart curling machine and method that can collect its own motion parameters in real time, but the smart curling ball has a large volume and can only detect the motion state data of the curling ball, and does not provide further processing. and display module, and a scientific and effective technical and tactical analysis system is not provided for athletes; Jin Jing et al. proposed a curling ball motion state estimation method in CN111709301 A, but in complex curling games or curling training, the curling There is often more than one curling ball on the road. The trained curling ball target detection network cannot accurately identify the curling ball that needs to be tracked, and the curling handle angle obtained by it is only an estimation result, which cannot provide accurate information for wheelchair curlers. reference data
