Title:
画像撮影システム、画像撮影方法、および画像撮影プログラム
Document Type and Number:
Japanese Patent JP4779041
Kind Code:
B2
Abstract:
The present invention relates to segmented image taking and merging processing of segmented images with logical consistency with high efficiency at low cost and thereby enables easy formation of a high-definition merged image. An imaging system 10 includes a distance calculator 110 that calculates a distance from an imaging object to a fixed position of a digital camera by using a predetermined formula and stores the calculated distance; a resolution setting unit 111 that sets and stores hierarchal resolutions; a frame layout unit 112 that executes a process for each of the resolutions, the process including forming segment frames by dividing an angle of view of an image taking area by a predetermined angle, laying out the segment frames so that focus areas in respective segment frames overlap, and storing information on a layout of the segment frames and the corresponding resolution as a segmented image taking plan; a segmented image taking instruction unit 113 that sends the digital camera and a motor-driven pan head an instruction to take images of the segment frames from a single viewpoint for each of the resolutions, based on the segmented image taking plan, and acquires and stores a segmented image; and a segmented image merging unit 114 that executes a process for each of the segmented image taking plans, the process including forming a base image by enlarging each of captured images of a predetermined segmented image taking plan to a one-step-higher resolution, merging together segmented images obtained by a segmented image taking plan having the one-step-higher resolution by aligning each of the segmented images through pattern matching between the segmented image and the base image, and storing a merged image.
