Position and posture for dynamic target measurement problem is widely studied. Researching the testing and calibration model of the parallel optical axis stereo vision, and establishing non-contact measurement system of dynamic target’s position and posture. Measurement system uses double CCDs to capture vibration images of the target. System extracts the target pixel position information to calculate the spatial coordinates of the target point, then according to the target pixel position changes the whole process, to calculate the displacement variation in three dimensions, finally, count out the target’s position and posture. Verified by the static and dynamic experiments, results show that the measurement accuracy is about 0.1mm, the relative error is less than 5%, meeting the engineering test requirements. Measurement system has the features of compact, high accuracy and applicability, and achieving the purposes of intellectualized test and data analysis process automation. It can be widely used to measure objectives’ three-dimensional space motion parameters and space gesture in engineering tests area, etc.
