摘要:
An image processing method and an apparatus therefor calculating the rotations and the magnifications of a plurality of image pick-up devices, which are located at different positions and rotations and rotates, and pick-up images of the same object in a three-dimensional space, from the following equation by matching the image picked-up by the two arbitrary image pick-up devices, extracting the corresponding points, and detecting the coordinates values thereof on each image, ##EQU1## where, {expression}.sub.y : y component of the expression,{expression}.sub.z : z component of the expression,x,y,z: coordinate values of a point in a three-dimensional space,X.sub.L ', Y.sub.L ', X.sub.R ', Y.sub.R ': coordinate values of x, y on both images,.theta..sub.L, .phi..sub.L, .alpha..sub.L, .phi..sub.R, .alpha..sub.R,: differences in the rotation from the x-, y-, and z-axes of both image pick-up devices from the state to become a reference,f.sub.L,f.sub.R : magnifications of both image pick-up devices.
