A target shooting detection method for a chest bitmap

Abstract

The invention discloses a target shooting detection method for a chest bitmap. The method comprises the following steps: a, segmenting an original image of a target surface of the chest bitmap to obtain a target surface segmented image of the chest bitmap; b, performing target spot detection; c, performing target center detection and ten-ring loop line ellipse fitting; d, judging a ring value to obtain a target score; and e, mapping the target surface segmentation image and the target point score of the chest bitemap back to the original image. According to the method, the target shooting image is acquired by using image acquisition equipment, the training safety is improved, the target shooting result is analyzed without geometric correction, the target shooting score is automatically acquired, the accuracy is good, the target shooting result can be guaranteed to be fair and justice, the troop training efficiency is improved, the shooting angle of the acquisition equipment has no excessive requirements, operation is simple, the environment adaptability is high, and popularization is facilitated.

Description

technical field [0001] The invention relates to the technical field of target detection, in particular to a method for detection of chest ring targets. Background technique [0002] Live ammunition shooting is the most common military training subject in the army, but at present the overall situation of our army's target training equipment is still relatively backward, and most troops still use manual target reporting for shooting training, which is inefficient and less safe , and it is easy to generate cheating behavior when manually reporting the target, which is not conducive to the improvement of the shooting level of the soldiers. [0003] In order to achieve the goal of strengthening the army with science and technology, some researches on the automatic target reporting system have been done in our country. According to the realization principle of the automatic target reporting system, it can be divided into double-layer electrode short-circuit sampling system, light...

Problems solved by technology

Another way is to automatically perform geometric correction by detecting key points. However, due to the changeable environment and target surface, it is difficult to accurately obtain matching points. Therefore, it is difficult to automatically correct the actual chest ring target area in practical applications.

[0005] my country's live ammunition training ranges are often in outdoor scenes, and the target detection results are easily affected by environmental factors such as lighting, resulting in poor robustness of the target reporting system based on image processing
