Method for improving target scoring precision in bow-and-arrow image scanning target scoring

Abstract

The invention provides a method for improving the target scoring precision in bow-and-arrow image scanning target scoring, which comprises the steps of firstly installing and debugging a target scoring system, and enabling an arrow target imaging straight line to be mutually parallel to a camera view horizontal center line through adjusting a first camera and a second camera of the target scoring system; then constructing a first rectangular coordinate system and a second rectangular coordinate system, building a first straight-line equation in the first rectangular coordinate system, and building a second straight-line equation in the second rectangular coordinate system; unifying the first straight-line equation and the second straight-line equation to the same rectangular coordinate system through coordinate transformation so as to acquire coordinates of an actual arrow landing point; and finally calculating the straight-line distance between the actual arrow landing point and a first assistant positioning member, comparing the straight-line distance with the spacing of each ring of an arrow target, and determining a target score of the arrow. An arc projection principle is adopted to determine the actual position of the arrow landing point, and thus the target score is measured and calculated, so that the target scoring precision is improved. In addition, the method is low in implementation cost.

Description

technical field [0001] The invention relates to the technical field of bow and arrow target reporting, in particular to a method for improving target reporting accuracy in bow and arrow image scanning target reporting. Background technique [0002] At present, bow and arrow, as a new popular sport in China, is getting more and more attention and love from the public. However, due to special circumstances such as the difference in the depth of the arrow entering the target and the arrow always standing on the target, it is very difficult to report the readings of the bow and arrow target. Therefore, the accuracy of the bow and arrow target reporting has always been a problem. [0003] Traditional bow and arrow target reporting methods include image scanning target reporting, infrared target reporting, ultrasonic target reporting and other methods. In the image scanning target reporting method, the two-dimensional scanning method of the root of the arrow is usually used. In t...

Problems solved by technology

In the two-dimensional scanning method at the root of the arrow, the traditional method is to interpret the projection of the arrow point on the target as a uniform pixel distribution on a straight line passing through the bull's-eye and perpendicular to the line connecting the bull's-eye and the ca
