Construction of panoramic depth image

Abstract

We propose a method which constructs a panoramic depth image. We use a digital still camera and a panoramic lens. The lens has omnidirectional mirror that is pointed in the camera direction and the camera can shoot a horizontal panoramic image through it. We use two panoramic images to construct a panoramic depth image. Each image is photographed at different height and there is the parallax difference between these images. Our method seeks corresponding point between these images and calculates the depth value at each pixel. In addition, we had some experience to evaluate effectiveness of our method. The results shows that our method is useful for making three-dimensional contents form the real scenery.
