Abstract
An image processing system performs a position-matching operation on first and second images, which are obtained by photographing the same object a plurality of times. A plurality of shift points are detected in the second image. The shift points correspond to fixed points, which are dispersed throughout the whole of the first image. The second image is divided into a plurality of partial images, the vertices of which are positioned at the same coordinates as the fixed points in the first image. Each of the partial images are shifted to the shift points to transform the partial images so that corresponding transformed partial images are produced. The transformed partial images are combined to form a combined image.
Claims8
An image processing system performing a position-matching operation on first and second images, which are obtained by photographing the same object a plurality of times, so that said first and second images are composed, said image processing system comprising:
- a shift point detecting processor that detects a plurality of shift points in said second image, said plurality of shift points corresponding to a plurality of fixed points that are dispersed throughout the whole of said first image;
- an image dividing processor that divides said second image into a plurality of polygonal partial images, the vertices of which are positioned at the same coordinates as said fixed points in said first image;
- an image transforming processor that shifts the vertices of each of said partial images to said shift points to transform said partial images so that corresponding transformed partial images are produced;
- and
- an image combining processor that forms a combined image by combining all of said transformed partial images in such a manner that the common shift points remain in their same positions.
An image processing method performing a position-matching operation on first and second images, which are obtained by photographing the same object a plurality of times, so that said first and second images are composed, said image processing method comprising:
- a detecting step for detecting a plurality of shift points in said second image, said plurality of shift points corresponding to a plurality of fixed points that are dispersed throughout the whole of said first image;
- a dividing step for dividing said second image into a plurality of polygonal partial images, the vertices of which are positioned at the same coordinates as said fixed points in said first image;
- a shifting step for shifting the vertices of each of said partial images to said shift points to transform said partial images so that corresponding transformed partial images are produced;
- and
- a forming step for forming a combined image by combining all of said transformed partial images in such a manner that the common shift points remain in their same positions.
