| 摘 要： | 分析基于Mart算子的标定算法存在易受环境光及噪声影响、精度不够高的不足，根据计算机视觉标定的目标要求，通过动态阈值分割、边缘提取、轮廓跟踪和两步法标定算法等处理策略，克服了传统标定算法的缺点，并实现了计算机视觉摄像机标定的整个过程自动化．实验结果证明，该标定算法鲁棒性强，操作简便，抗噪声、抗环境光性能好，标定精度高而且稳定．

| Abstract: | According to the requirements of the calibration of computer vision, a series of effective steps including dynamic threshold dividing, contour picking, contour tracing, and two stage calibration algorithm; and the whole process automation of the calibration were achieved. The result showed that this calibration algorithm was characterized by high robustness, easy operation, non noisesensitivity, and high-accuracy. |
