Abstract

The invention discloses a screen seamless display method based on distributed projection. The method comprises the steps of dispersing an overlapping region of the distributed projection after geometric calibration into a plurality of spatial quadrangles, and carrying out the color and / or brightness adjustment of the spatial quadrangles to be adjusted through taking the spatial quadrangles as units, thereby improving the detailed degree of edge fusion, and improving the color purity of the overlapped region. The color and / or brightness adjusting algorithm applied in the method is simple in principle and high in calculation speed, the selling price of a seamless splicing control software system can be greatly reduced, and the use requirements of small and medium-sized enterprises for large splicing screens are met. The invention further 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 distributed projection-based screen seamless display method and system. 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 through multi-screen splicing has been widely used. Screen display and clear and realistic display effects have greatly improved the work efficiency in monitoring, security, conferences, simulation and other fields, and at the same time 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 uses professional-grade ultra-narrow-edge LCD display unit splicing, or through the splicing control software system to achieve a large-screen splicing display effect. At p...
