Embodiment Construction

[0035] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0036] Embodiments of the present invention include the steps of installing and debugging the target reporting device, determining the plane equation of the target, and judging the number of arrow rings:

[0037] (1) Installation and commissioning steps of target reporting device:

[0038] Select two 5-megapixel cameras facing the archery target and fix them in parallel. Make sure that the installation plane of each camera base is parallel to the ground. The camera lens should point to the archery target as vertically as possible. The vertical distance from the archery target is about 1.5m. position, and obtain the relative distance between the cameras, when the target surface occupies 1 / 2 to 2 / 3 of the camera field of view and forms a clear image, the camera installation and debugging is completed;

[0039] (2) Determine the target plane equation step...

Abstract

The invention discloses a method for improving target scoring precision based on machine vision and belongs to image processing methods. According to the method, the problem of an identification error caused by arrow body blocking in an existing method is solved, and the target scoring accuracy rate is increased. The method for improving the target scoring precision based on the machine vision comprises the steps of target scoring device mounting and debugging, arrow target plane equation determining and arrow landing ring number judging. A target scoring system adopted in the method is simple in structure, low in implementation cost and high in adaptability. By reconstituting a three-dimensional coordinate of an arrow body and an arrow target plane, the problem of the identification error generated due to the fact that the intersection point of the arrow body and the arrow target plane is blocked is effectively solved. Compared with the prior art, the step of detecting arrow body stability is simplified, and the target scoring precision is improved.

Description

technical field [0001] The invention belongs to an image processing method, in particular to a method for improving target reporting accuracy based on machine vision, which is suitable for arrow target reporting in archery sports. Background technique [0002] Archery can not only achieve the purpose of fitness, but also help to improve the physical fitness of ordinary residents, and can also be used as a recreational and competitive sports item. Therefore, many countries are currently promoting and popularizing this sport; The demand and requirements for archery targets are also gradually increasing. [0003] The commonly used archery targets in the past are often placed at a certain distance from the shooter. After the shooting is over, special staff will take measurements and record the number of archery rings; this method of work not only consumes a lot of manpower and material resources, but also Inefficiency is not conducive to the promotion of this sport. Therefore ...
