Multi-channel data fusion correction method

Abstract

The invention provides a multichannel data fusion correction method and belongs to the technical field of data processing. The method includes the following steps: arranging K projectors; dividing a projection screen into K areas; enabling one projector to be corresponding to one area so that each projector projects an equal-interval grid image; uniformly arranging (m+1)*(n+1) control points on the grid image and adjusting the coordinate of each control point so as to enable an observer to observe a normal perspective projection image on the projection image; recording an adjusted coordinate value of each control point and then constructing a deformation function Q (i,j) according to the adjusted coordinate values and then according to the function Q (i,j), carrying out deformation on a to-be-projected image; and carrying out data fusion on two adjacent images. The multichannel data fusion correction method is capable of enabling of a plurality of projectors to project one image to an irregular screen so as to obtain a seamlessly connected image.

Description

technical field [0001] The invention relates to a multi-channel data fusion correction method, which belongs to the technical field of data processing. Background technique [0002] Multi-channel projection is to realize the simultaneous and synchronous projection of multiple projectors. Each projector can project the content of different scenes, which greatly improves the amount of displayed information and expands the scope of vision. Multi-channel projection technology has a good application prospect in the fields of virtual geographical environment, digital city, urban or garden landscape planning and design, military battlefield simulation, visual forest management, dynamic simulation of soil erosion scenarios, etc. In order to improve the visual effect, irregular screens such as ring screens, arc screens, and ball screens are often used in multi-channel projection technology, but image splicing is the key technology for projection on irregular screens.

Problems solved by technology

Hard-edge splicing has obvious dividing lines (that is, the so-called physical splicing), which cannot realize integrated panoramic display; overlapping splicing means that the images projected by two projectors overlap in a superimposed manner at the splicing place, and there is a " "Bright band effect", the spliced ​​image does not have a sense of integration, but has an obvious "stitching feeling". Although there is no physical stitching seam in this overlapping splicing, there are optical bright bands, which cannot achieve a perfect "seamless" effect
