Abstract

The invention discloses a screen seamless display method based on distributed projection, which discretizes the overlapping area of ​​the distributed projection after geometric calibration into a plurality of spatial quadrilaterals, and uses the spatial quadrilateral as a unit to perform adjustment on the spatial quadrilateral to be adjusted. The color and / or brightness adjustment improves the refinement of edge fusion and helps to improve the color purity of overlapping areas; and the color and / or brightness adjustment algorithm used in the present invention is simple in principle and fast in calculation speed, which is conducive to greatly reducing noise The price of the seam splicing control software system meets the needs of small and medium-sized enterprises for splicing large screens. The invention also provides a screen seamless display system based on distributed projection.

Description

technical field [0001] The invention relates to the technical field of large-screen seamless display, in particular to a method and system for screen seamless display based on distributed projection. Background technique [0002] With the continuous integration and development of LCD splicing technology and control technology, in the field of high-end large-screen display system engineering, large-screen image display formed by multi-screen splicing has been widely used. Screen display and clear and realistic display effect have greatly improved the work efficiency in the fields of monitoring, security, conference, simulation and simulation, and promoted the rapid progress of the technical level of these industries. [0003] The so-called LCD seamless splicing screen display technology is a technology that adopts the splicing method of professional-grade ultra-narrow-edge LCD display units, or realizes the large-screen splicing display effect through a splicing control softw...
