| 摘 要： | 本文针对单摄像机成像特点,首先建立其实际成像数学模型,为快速高精度的标定摄像机参数,靶标采用平行网格线靶标,有效利用直线的平行性约束条件,可高效的求取目标点,此种方法先求解摄像机纵横比,然后利用参数分离的方法通过迭代求解其余模型参数,从而简化了求解过程,将标定结果与Tsai法相比较可知,标定精度相当。

| Abstract: | According to the characteristic of imaging by single camera, the actual math-model is established firstly.Because of parallel restriction of lines, targets are made of points of intersection of parallel lines, therefore object points can be obtained efficiently to calibrate camera parameters with high speed and high precision.Aspect ratio of camera is achieved and then iterative method is used to solve other model parameters based on parameters separation, which simplifies solution process. Experimental results convincingly show the high precision and ultra fast performance of our method compared with Tsai method. |
