<P>PROBLEM TO BE SOLVED: To automatically form and display a two-dimensional image observed from an observation direction, regarding an object whose observation direction is defined. <P>SOLUTION: The same object is captured by a camera from imaging points Q1, Q2 to obtain captured images P1, P2. The image P1 is analyzed to recognize a reference plane R of interest on the object, and points S11-S14 corresponding to four points S31-S34 on the reference plane R are obtained on the image P1. Features of the images P1, P2 are compared to obtain points S21-S24 corresponding to the points S11-S14 on the image P2. Three-dimensional coordinate values of the points S31-S34 on the reference plane R are obtained from eight points S11-S24 on the images P1, P2 and information on the location and direction of the camera. Based on the coordinate values of the points S11-S24 and points S31-S34, a transformation formula for transforming the images P1, P2 on an xy coordinate system into images on a uv coordinate system is derived, and the transformation formula is used to obtain transformed images of the images P1, P2 on the uv coordinate system. These transformed images are composed to obtain a display image. <P>COPYRIGHT: (C)2011,JPO&INPIT |
