Abstract
Multiple cameras with different orientations capture images of an object positioned at a target position relative to the cameras. Images from each camera are processed in parallel to determine depth information from correspondences between different regions within an image captured by each image capture device in parallel. Depth information for images from each camera is modified in parallel based on shading information for the images and stereoscopic information from the images. In various embodiments, the depth information is refined by minimizing a total energy from intensities of portions of the images having a common depth and intensities of portions of the image from shading information from images captured by multiple cameras. The modified depth information from multiple images is combined to generate a reconstruction of the object positioned at the target position.
