Based on high speed photography video image sequences, target's motion parameters can be obtained by interpreting image sequences and calculating with interpretation results. The principle of traditional interpretation methods all obtained spatial coordinates of target's point based on target plane coordinates of target's point. If obtaining 3D attitude of rigid(spatial orientation of target's axis)with the information of two points' spatial coordinates, then the precision is difficult to reach the expected value. But if we interpret by extracting target's axis, then the interpretation precision and measuring precision can be advanced. In this paper interpretation technique of target's axis automatic detecting and tracking based on target's model and "WYSWYG" is proposed, detecting method of axis interpretation precision is introduced and the precision is analyzed.
