## Abstract (Summary of the Work)

Determining camera location from image to space point correspondences (i.e., 2-D and 3-D correspondences) is a very basic problem in image analysis and cartography. It can be applied to aircraft location, robot calibration and so on. Roughly, this problem can be considered as estimatimg the three dimensional location from which an image was taken by a set of recognized landmark appearing in the image. The camera location determination problem is formally defined as follows: Given a set of m control points, whose three dimensional co-ordinates are known in some co-ordinate frame, and given an image in which some subseet of m control points is visible, determine the location (relative to the co-, ordinate system of the control points) from which the image was obtained. In solving this problem, we shall assume that the focal length of the camera is known and the 2-D to 3-D line or points correspondences are given.Here, not finding the absolute location of the we are camera, rather the location of one camera relative to an another camera, i.e. the relative orientation of two cameras.This report is organized as follows. A brief description of perspective projection, camera model and stereo imaging is sited in section 2. Camera calibration is defined in the section 3. Section 4 presents formal description of the problem and section 5 describes the algorithm used here. Section 6 will give some experimental results.
