论文总结了多光轴在空间旋转时形成的原因及其误差量,形成了兼顾安全和便捷的技术途径:首先以摄像机模拟非可见且对人眼有危害的激光器;其次设计加工出一种专用的回转基准调校基座和基准光源,通过转动基座,检测出摄像机光轴和可见光轴在空间不同相对位置的误差,采用双光楔方法进行调节;最后依托过渡工装使激光器光轴相对其安装面的精度与摄像机一致,由此保证了激光轴与可见光轴在任意方位角处均保持平行;其平行度误差不超过0。

性质:将图像(或分子)绕一定轴线转动一定角度后能使图像复原的一类对称动作。旋转据以进行的轴线称作旋转轴,使图像绕轴后复原的最小转角称作基转角α。设α=2π/n,显然,旋转角为α整数倍的角度均能使图像复原,不难论证,在2π角度范围内独立、不等同旋转对称动作的种数为n。
