Abstract:The inter-reflection phenomenon in immersive projection systems seriously affects the effect of projection, the projection compensation task can reduce the influence caused by the inter-reflection by modifying and compensating the input image so as to obtain a better imaging effect. In this paper，an inter-reflection prior is proposed, which means that the color effect of the region where inter-reflection occurs is very close to the maximum 256 due to the light superposition effect. Therefore, inter-reflection information can be obtained through the regional channel pixel of the image. The Inter-Reflection Compensation Network (IRCN) proposed in this paper generates an inter-reflection mask value through the inter-reflection prior, so that the IRCN can eliminate the excess interreflection in immersive projection environments. To verify the IRCN model, the erperiment were performed on more than 5000 pairs of projected image datasets and curved projection system, and fold projection system.Compared with the existing projection compensation methods, the experiment results show that IRCN has obvious advantages in objective evaluation indicators such as PSNR, RMSE, SSIM, mean and standard deviation analysis. The proposed IRCN can effectively utilize the inter-reflection prior information to compensate for the inter-reflection phenomenon in the immersive projection environment, and enhance the projection effect based on balancing the training time.
