Abstract

The invention discloses a camera auxiliary correcting method, device and system based on image fusion processing, so that efficiency and precision of geometric correction, color correction and / or fusion zone correction and relevant corrections are improved. The method comprises the steps that correction data are preset, and corresponding correction results are output and displayed on a projection screen through a projector; a camera is ordered to take a photo, and the essence characteristic parameters of the correction results on the photo are sampled and extracted; the correction data are adjusted according to the relationship between the essence characteristic parameters and target characteristic parameters, corresponding correction results are output and displayed on the projection screen through the projector, and then photo taking, comparison and adjustment are carried out, according to the loop, the process is over until the essence characteristic parameters and the target characteristic parameters are consistent or within a certain error range, and the final correction data are obtained.

Description

technical field [0001] The present invention relates to the technical field of image processing, in particular to a camera-assisted correction method, device and system for image fusion processing. Background technique [0002] Image fusion processing is a solution for image projection fusion processing, which is to overlap the edges of the pictures projected by a group of projectors, and display a brighter, super large, high-resolution entire picture without gaps through fusion technology , the effect of the picture is like a picture projected by a projector, which is widely used in command centers, video conferencing, multimedia multi-function halls, etc. [0003] The key technologies of image fusion processing are mainly geometric correction technology, color correction technology, fusion belt correction technology and other image processing technologies. The image fusion processor needs to send the pictures after various corrections to the corresponding projectors to ach...
