Abstract:
    The invention discloses a correction method of large scale three-dimensional paste-up display wall, multi-bench projectors are driven by Linux trunked system, two projectors are a group, and it is separately connected with two outputs of the same trunked node, the images projected by projectors are geometry corrected, marginal anabranched and color corrected by method of computer sight, the projected images are montaged to a uniform three-dimensional display image with high distinguishability and large scale. The invention proceeds seamless geometry correction and color correction based on software and decrease hardware cost greatly; the correction data can be obtained by method of computer sight to decrease the maintenance cost of the display wall greatly; besides, the number of projectors, display size and distinguishability can be configured flexibly according to specific demand, the large scale view can be real-time plotted by adding trunked node.
