Picture generating apparatus and picture generating method
First Claim
1. A picture generating apparatus, comprising:
- at least two image pick-up means, for picking up an image of an object to be imaged, respectively disposed at different positions;
correlation detecting means for comparing, with each other, on an epipolar line which is an intersection line of an image pick-up plane of the image pick-up means and a plane determined by a line of sight connecting a virtual position and the object to be imaged, and a line connecting an optical center of the virtual position and an optical center of a detection camera, respective picture data generated by the respective image pick-up means to detect correlation therebetween; and
distance picture generating means for generating distance picture indicating distance between a virtual position and the object to be imaged on the basis of the correlation detected by the correlation detecting means.

Abstract
A picture generating apparatus according to this invention comprises: two image pick-up devices 3a, 3b or more adapted for picking up image of an object 2 to be imaged to generate picture data and respectively disposed at different positions; a correlation detecting section 5 for comparing, with each other, respective picture data generated by the respective image pick-up devices 3a, 3b on epipolar line determined by connecting correspondence points of line of sight connecting virtual position A and the object 2 to be imaged and line of sight connecting position of each of the image pick-up devices 3a, 3b and the object 2 to be imaged to detect correlation therebetween; and a distance picture generating section 5 for generating distance picture indicating distance between virtual position and the object to be imaged on the basis of correlation detected by the correlation detecting section 5.
