摘要

PPROBLEM TO BE SOLVED: To improve precision and efficiency of camera calibration. PSOLUTION: A planar board 1, on which a block pattern is printed, is imaged by a camera C1, C2. Feature points are extracted from captured image data A, B (S301). Initial blocks are selected from block patterns photographed in the image data A, B (S302) and the initial blocks are made correspondent to each other (S303). An initial plane transformation matrix is determined from correspondent point coordinates of the initial blocks (S304). A neighboring block of a previous block, in which feature points of the image data B have been made correspondent, is selected (S305) and correspondent positions, on the image data A, of the feature points in the neighboring block are determined from the plane transformation matrix calculated just before (S306). Near the correspondent positions, the feature points of the image data are searched and recorded (S307) and from the search result, the transformation matrix is calculated again (S308). The steps of S305-S309 are iteratively performed upon all the blocks. PCOPYRIGHT: (C)2009,JPO&INPIT

要解决的问题：提高相机校准的精度和效率。

解决方案：通过照相机C1，C2对上面印有块状图案的平板1进行成像。从捕获的图像数据A，B中提取特征点（S301）。从图像数据A，B中拍摄的块图案中选择初始块（S302），并使初始块彼此对应（S303）。从初始块的对应点坐标确定初始平面变换矩阵（S304）。选择已使图像数据B的特征点对应的先前块的相邻块（S305），并从平面确定相邻块中的特征点在图像数据A上的对应位置紧接在此之前计算的变换矩阵（S306）。在对应位置附近，搜索并记录图像数据的特征点（S307），并且根据搜索结果，再次计算变换矩阵（S308）。在所有块上迭代地执行S305-S309的步骤。
