A projection picture adaptive fusion and splicing method and system

Abstract

The present application belongs to the technical field of image data processing, and discloses a projection picture adaptive fusion and splicing method and system, which comprises the following steps: acquiring preset calibration data and current frame overlapping images of an overlapping area of adjacent projectors, wherein the calibration data comprises a brightness distribution graph, a standard fusion weight graph and a normalized definition difference graph; performing texture analysis on the overlapping images to obtain image frequency characteristic values; combining the definition difference graph and the frequency characteristic values to determine a weight offset requirement value; applying an offset to the standard fusion weight under the constraint that the brightness variation does not exceed a preset tolerance, generating a dynamic fusion weight graph through spatial smoothing processing, and outputting the projection signals of the projectors according to the weighted rendering. According to the present application, the fusion weight is adaptively adjusted according to the image texture characteristics, the weight is biased towards the projector with higher definition in the high-frequency texture area, and the brightness uniformity is ensured through brightness constraint and spatial smoothing.
