摘要
给出了一种实用的摄像机标定方法。首先通过预标定过程确定摄像机光心坐标和感光单元的纵、横向间距,然后结合自定义的摄像机成像模型利用径向平行约束求解其余的摄像机内外参数,最后利用自制的平面模板对该方法进行了实验验证。结果表明,该方法不仅操作简便,在一般硬件条件下也可获得满意的精度,具有良好的实用价值。
It presents an applied calibration technique. Firstly, it seeks the optical centre of camera with precalibration, as well as horizontal and vertical distances between two sensor units. Then based on radio array constraints the other parameters are solved by constructing a new camera model. The experiment with this homemade planar template shows that the method is feasible, accuracy and has nicer practical value.
