| The technology of image processing are the technology used in processing, analyzing and comprehending the vision information by right of computer. Along with the immense progress in the science and technology of computer, the technology of image processing are extending the applicable field of it. And some robust algorithms of unage processing have been used in consumptive product.Now, the Military Automatic Target-Scoring System(MATSS) based on the technology of unage processing, as a land of new target-scoring technology, begin to be applied in the project of military shooting training and competition.In this paper, the design and realization of the image recognition function used in Military Automatic Target-Scoring System will be dissertated in detail.The work flow of MATSS can be composed of the three phases: the initialization of system, the pretreatment of image and the recognition of unage. The kernel function in the three phases is:Geometry Rectification: in order to eliminate the influence of aberrance on the unage, the target unage should be rectified first.Median Filter: image smoothing, to reduce the interference form noise and preserving the quality of image edge.Image Subtraction: eliminate the useless data as cirques and figures in the image in order to be ready for the bullet-spot's segmentation. This is the kernel in the technologies used in MATSS.Threshold Selection and Image Binary: the fundamental of bullet-spot's recognition.Bullet-spot's Recognition and Scoring: a ameliorated eigenvector- matching be used in the final function is faster algorithm than conventional Template-matching. |
