The Research Of The Automatic Target-scoring System Based On Image Processing

With the rapid development of information technology, image processing technology has become an indispensable science and engineering field of powerful tools. Most of shooting trainings are still using traditional manual target-scoring systems, which have some defects in security and efficiency,but Automatic Target-scoring System is fast, efficient and precise,Which has advantages compared with the manual method. The Automatic Target-scoring System will make great progress in the shooting training. The main work of this paper is as follows:1. In detail Status of current study on automatic target-scoring systems are described. The Automatic Target-scoring System is totally designed, including software design and hardware design in two parts. Hardware parts which includes the Video Capture System and wireless transmission,to solve the problem of remote collection of target images.2.The research of the Video Capture System and image pre-processing, focusing on the improvement of image quality, in order to facilitate the ex traction of information regions of interest,this paper mainly used Median Filter ,Image Subtraction, Binarization, Morphological Filter, etc .The way is respectively simulated. Image Subtraction is the kernel in the technologies used in this dissertation and key to extract Bullet-spot3. The methods of identification of bullet holes and the ring to determine have the value of a detailed study, using the image subtraction technique effectively extract bullet holes, the use of three given coordinates of the circle determine as bull's-eye. According to the geometric relationship between the core point of the bullet-hole and the loop lines, the corresponding shooting score is calculated. Develop interactive software of Automatic Target-scoring System to verify the validity and correctness of the algorithm.Large amounts of simulating show that our automatic target-scoring system is efficient and precise by a large of exercises.
