摘要
结合计算机视觉技术和CCD测量原理,给出了一种运动目标姿态参数的测量方法,并推导了目标姿态测量的数学模型。对可能存在的误差源进行了分析,并提出了解决方法。该方法通过三个与CCD相匹配的标定点测量,采用四元法描述姿态,使得系统结构简单、速度快;仿真结果表明,系统角测量精度可达到1′,系统可以广泛应用于运动目标姿态的近距离测量。
Optical measurement for attitude parameters of moving targets based on computer vision principle and CCD technology is presented. The attitude algorithm is deduced from the system model. Errors existed in the system are analyzed and their resolving methods are brought forward, As special frequency of three light points is matched to CCD camera and quaternion theory are used in the measurement, the system possesses the following advantages; simple configuration, rapid algorithm and high precision （1＇）. The system is worthwhile using for the attitude measurement of other dynamic targets.
