成果介绍

本发明适用于光学测量技术领域，提供了一种大畸变镜头下的高精度圆形标志点中心定位方法及装置，首先，利用大畸变镜头的相机采集N个摆放姿态下的印制有圆形标志点图案的标靶图像，得到N个标靶图像；然后，对标靶图像进行椭圆中心坐标提取，并标定相机的固定内部参数和N个外部参数；然后，反向投影变换计算生成N幅平行于世界坐标系中XW‑OW‑YW平面的标靶图像；对N幅标靶图像分别进行圆心提取计算，并进行正向投影变换计算到相机的成像平面，得到N组坐标作为圆形标志点中心的图像坐标继续进行标定，并更新固定内部参数和N个外部参数；若圆形标志点中心的图像坐标趋于稳定，则完成定位；本发明的方法实现了高精度圆形标志点中心定位。
