Abstract: Military symbol is a basic graphic element in the situation picture, which has an important meaning in military command and control systems. The current military symbol testing mostly adopts manual testing methods, which has low efficiency. This paper focuses on this issue, designs and implements an automated testing method for military symbols. Firstly, it achieves the target of automatic military symbol plotting; and then mainly uses the technologies of morphological expansion, corner detection and image binarization for image analysis, which gives a design and implementation on the military symbol testing for three commonly used attributes of line width, softening and color. Finally, according to the testing results ,it automatically builds the testing reports. The experimental results show that, this paper provides a feasible, effective automated testing way for the validation of military symbol correct drawing, and implements a new applicable scene for image analysis in the automated testing domain.
