针对动态目标振动位姿测试问题，研究平行光轴立体视觉测试及标定模型，建立非接触动态目标空间位姿测试系统。通过双 CCD 拍摄目标靶振动图像，据目标点像素位置信息获得目标点空间坐标，再由像素始末位置变化求解点偏移量，进而求出动目标空间位姿。通过静、动态试验验证，测量精度约为0．1 mm，相对误差小于5％，满足工程测试要求。结果表明，测试系统结构紧凑，测量精度高，适用性强，能实现位姿测试智能化及数据分析处理自动化，可用于测量三维空间中目标的运动参数及空间姿态等。

The testing and calibration model of the parallel optical axis stereo vision was discussed and a non-contact measurement system for dynamic target's position and posture was established.In the measurement system,double CCDs were used to capture vibration images of the target,the target pixel position information was extracted to calculate the spatial coordinates of the target point,then according to the target pixel position changes during the whole process,the displacement variation in three dimensions was calculated and finally,the target's position and posture were solved. Verified by the static and dynamic experiments,the results show that the measurement accuracy is about 0.1mm and the relative error is less than 5%,meeting the engineering test requirements.The measurement system has the features of compactness,high accuracy and applicability.It can achieve the purposes of test intellectualization and data analysis automation.It can be widely used to measure objectives'three-dimensional space motion parameters and space gesture in engineering tests.
