基于三目视觉的弹丸姿态测试

Projectile Attitude Measurement Based on Trinocular Vision

提出了一种三目视觉弹丸姿态测量方法,利用三个相机构建了三目立体视觉系统,采用投影面交线法重建弹丸中轴线的方向向量得出弹丸的姿态角,分析了相对双目检测系统的优势,并对搭建系统进行了验证。试验结果表明,三目姿态测量系统可以有效测出弹丸的姿态角,静态误差小于0.35°,相对于双目系统具有更高的稳定性与可靠性。

A three-eye visual projectile attitude measurement method was proposed.The three-eye stereo vision system was constructed by using three cameras.The direction vector of the projectile axis was reconstructed by the projection surface intersection method to obtain the attitude angle of the projectile.The advantages of the binocular detection system was analyzed and the system for experimental verification was built.Experiments were carried out indoors.Several experiments showed that the trinocular attitude measurement system can effectively measure the attitude angle of the projectile,and the static error is less than 0.35°,which has higher stability and reliability than the binocular system.
