A improved automatic image interpretation method is introduced in this paper. At the same time, the composing, characteristic and functions of a new high-speed video recording and interpretation system are presented as well. The system uses a built-in memory of the high-speed CMOS camera to record the digital video sequence images and afterwards download the images to a hard disk or a DVD via a high-speed interface. The image sources for the image interpretation software are acquired in this way. Mathematical morphology method is used to remove the effect of noises for binary images and get clear boundary of a target. In allusion to different needs of automatic interpretation and semiautomatic interpretation, the system adopts dissimilar thinning techniques. In the case of existed resolution, the sub-pixel orientation is realized and the measure precision is improved. This system could be use for a reference for the development of other analogous systems.
