Feature point extraction of spot array calibration target

  • 摘要: 在摄像机标定过程中,提取标定模板图像特征点的精度是影响摄像机内外参数标定精度的重要因素。本文根据条纹投影三维轮廓测量实验系统的要求制作了点阵列标定模板,在图像处理边缘理论的基础上,以圆的解析特性为依据,采用坐标转换思想,引进圆系描述点、圆对应关系,运用统计学理论,提出提取点阵列标定模板图像特征点的新方法,并通过实验验证了该方法的正确性和可行性。为下一步的摄像机内外参数求解做了铺垫。
    Abstract: The feature point extraction of calibration target during the camera calibration is crucial and may affect the precision of camera internal and external parameters. Based on several typical camera calibration targets, a spot array target is designed as required by the fringe projection 3D profile measurement system. According to the image edge processing theory, a new method for feature point extraction of the spot array target is introduced, which includes the analytical characteristic theory of circle, the coordinate transformation, the corresponding relation of spot and circle, and statistical theory. The validity of this method is verified by experiment. This work can be used to solve camera internal and external parameters.
