Embodiment Construction

[0041] Figures 1 to 7 is the best embodiment of the present invention, the following is combined with the appendix Figures 1 to 5 This embodiment will be further described.

[0042] like figure 1 As shown in the figure, an intelligent ranging system for standing long jump based on computer vision includes a camera, a notebook, a ruler, an external graphics dock and a special jumping carpet. The ruler is placed perpendicular to the ground, and the camera is placed horizontally at a distance of 4.6m from the ruler along the vertical line of the midpoint of the ruler and connected to the laptop. The fixed placement position is selected because of the influence of OpenPose technology and camera perspective phenomenon. If placed in other positions, it is easy to lose the joint points of the human body or increase the ranging error, so that the overall test area is within the shooting range.

[0043] The external graphics card provides computing power support for the human gest...

Abstract

The invention provides an intelligent distance measuring method and system for standing long jump based on computer vision, and the method comprises the steps: carrying out the photographing of a landing point on a jump blanket during standing long jump through the computer vision technology through the cooperation of computer vision and a human body key point recognition technology, finally confirming the landing point through the human body key recognition, and calculating the long jump score. Meanwhile, the personnel waste is avoided, and the cost is relatively low. The system is developed through an open source framework OpenPose and a computer vision detection technology. According to the technical scheme, the landing actions of the vertical long jump are judged, such as hand supporting on the ground, slipping and stepping towards the rear legs, so that the universality and the practicability of the technical scheme are improved.

Description

technical field [0001] The invention belongs to the technical field of machine vision and image processing, and relates to a standing long jump intelligent ranging method and system based on computer vision and key points of the human body. Background technique [0002] In the existing related patented technology inventions, different types of sensors are commonly used, such as infrared sensors, embedded, grating ranging methods, laser ranging methods, etc. for ranging. When judging the landing posture, the feet are all used to calculate the standing long jump distance. However, most of the test standards use the closest landing point to the jumper as the distance from the measurement point to the jumper. Therefore, the existing measurement methods cannot truly reflect the final long jump performance. SUMMARY OF THE INVENTION [0003] In order to overcome the problems existing in the prior art, the present invention considers that there are various landing situations i...
