基于双目视觉的空间脱靶量测量技术研究

Space Miss-Distance Measurement Based on Binocular Vision Model

为了测量飞行目标的空间脱靶量,采用在指定区域附近放置凝视等待式双目相机,测量飞行目标位置、速度等参数,得到空间脱靶量信息。在建立数学模型后,设计了运动目标测量系统,并对系统误差进行了分析。实验和结果分析表明,该系统对运动小球的测量相对误差小于2%,验证了系统设计的可行性。

In order to measure the space miss-distance, the binocular intersection system is set up near the designated spot to detect the location and speed parameters of flying target by photograph. After the mathematical model of the system is devel- oped, an experiment for measurement of moving object is designed. Moreover, the system error is analyzed. Experiments and theoretical analysis prove the measuring error for moving ball is less than 2% and the system to be effective.
