Paper Abstract

In this work, we present a novel concept to sense 3D surface profile of scenes along with their color images. The method for achieving this functionality includes two isotropic light sources placed at different geometric locations, an optic apparatus for aligning the light rays projected onto the scene, and a high precision camera. To determine the pixel-wise distance information, the system captures two sequential images during the stropping of each light source in sequence. Then, the intensity of each pixel location in these two images are utilized for calculating the distance information of object points corresponding to pixel locations in the image to generate a 3D surface profile of a scene. The approach is suitable for both capturing color information and sensing 3D distance information in high definition format synchronously.
