摘要：

Two anti-light interference algorithms of point to point algorithm and image enhancement anti-light interference algorithm were proposed to solve the problem of image quality reduction due to the light interference in multi-projector display system. The corresponding mapping relation between camera and projector was built firstly, then the luminance and saturation of output images would be promoted according to the mapping relation and experimental data. To offset the effect of light interference indirectly, the image quality on display wall was enhanced by using a combination of various image enhancement algorithms. The theoretical derivations of the two algorithms were provided and experimental verification was implemented in a dome display system which was composed of 24 projectors. Finally, the experimental results demonstrated the validity of the proposed algorithms. ©, 2015, Editorial Department of Journal of Sichuan University. All right reserved.
