Title:
画像合成変換装置
Document Type and Number:
Japanese Patent JP4021685
Kind Code:
B2
Abstract:
A subject of the present invention is to form simply a mapping table, which transforms a picked-up image of a real camera into an image viewed from a virtual viewpoint, by a small amount of computation. An image transforming system of the present invention has an imaging means (10) for picking up a real image, a coordinate recording means (32) for recording a three-dimensional position on a projection model corresponding to a previously-computed pixel position of a virtual camera, a means for computing a positional relationship between the virtual camera and the imaging means (10), means (20)(30) for forming and recording a mapping table, which transforms the real image into an image viewed from the virtual camera, based on information of the positional relationship and information of the three-dimensional position recorded in the coordinate recording means (32), and a means (40) for mapping the real image by using the mapping table. The means for computing the positional relationship predicts the positional relationship from the installation position, and inputs it into the means (20) for forming the mapping table as a camera parameter when an installation position of the imaging means (10) is decided previously.
