内容紹介

Recent improvements in resolution, accuracy, and cost have made depth cameras a very popular alternative for 3D reconstruction and navigation. Thus, accurate depth camera calibration a very relevant aspect of many 3D pipelines. We explore what are the limits of a practical depth camera calibration algorithm: how to accurately calibrate a noisy depth camera without a precise calibration object and without using brightness or depth discontinuities. We present an algorithm that uses an external color camera to overcome the difficulties presented by a depth camera and show that a joint calibration obtains the best results. We apply this algorithm to calibrating the Kinect.
