In this paper, we present a system for real-time Diminished Reality using multiple smartphones. In this system, we assume multiple smartphones capture the same scene that is occluded by obstacles. Areas of the obstacles are extracted from each camera image replaced with image of the hidden areas which are captured using different viewpoint camera. In the proposed method, we suppose that the target scene can be approximated as a plane. Therefore, we compute Homography between each camera image by using natural features. Then, obstacle area which is not approximated as a plane can be removed by synthesizing the image warped with the Homography and the user viewpoint image. We can perform real-time processing because we send each camera image to PC which returns obstacle-removed images at every frame. We experimentally demonstrate the effectiveness of the proposed method using three viewpoint images.
