APPARATUS AND METHOD FOR DYNAMICALLY ADJUSTING DEPTH RESOLUTION

摘要

An apparatus for dynamically adjusting depth resolution is provided. The apparatus includes a depth capture module, an image capture module and a computing unit. The depth capture module obtains a set of images for disparity computation. The image capture module obtains a high-resolution image. The computing unit computes a disparity map and a corresponding depth map using the set of images obtained by the depth capture module, and sets a 3D region of interest according to a pre-defined object feature, the high-resolution image and the depth map. The 3D region of interest can be dynamically adjusted by tracking the movement of the object. In the 3D region of interest, the computing unit re-computes the depth map in higher resolution along Z axis by re-computing the disparity map in appropriate sub-pixels and allocating the required number of bits to store the sub-pixel disparity values.
