Abstract: <P>PROBLEM TO BE SOLVED: To provide a camera calibration technique for estimating the external parameter of a camera on the basis of coordinate information of four feature points when the internal parameter of the camera is a given parameter.  <P>SOLUTION: In the case where a world coordinate system is identical to a camera coordinate system, on the basis of two angles formed by four feature points in the world coordinate system, coordinate positions of the feature points in the camera coordinate system are estimated. A distance T formed with a straight line obtained by extending a visual line vector A is divided into eight and it is estimated which one of eight divided points is closest to the coordinate position where a feature point A is present. In the estimation, points B', C' and D' equal to the length of sides AB, BC and DA are calculated from among points on visual line vectors B, C and D with the eight divided points as base points, differences of angles B' and D' formed by the base points and the points B', C' and D' from the angles B and D are calculated at the respective points, one of the eight divided points most approximate to the feature points A, B, C and D and points B', C' and D' corresponding to that point are calculated.  <P>COPYRIGHT: (C)2011,JPO&INPIT
