Abstract
The performance of multi-projector display system is affected mainly by uneven projection screen brightness and anisotropic property of projection screen. A nonlinear optimization algorithm is proposed based on multi-view projector-camera system to solve these problems. By assigning different weights for each correction result, brightness differences of different view angles are balanced, and brightness adjustment is completed. For the overlapping region, double trigonometric function method is used to calculate the attenuation matrix of the projector. The light fusion is completed. Dual channel projection system is used to verify feasibility and effectiveness of the algorithm.
