We present an algorithm that simultaneously calibrates two color cameras, a depth camera, and the relative pose between them. The method is designed to have three key features: accurate, practical, and applicable to a wide range of sensors. The method requires only a planar surface to be imaged from various poses. The calibration does not use depth discontinuities in the depth image, which makes it flexible and robust to noise. We apply this calibration to a Kinect device and present a new depth distortion model for the depth sensor. We perform experiments that show an improved accuracy with respect to the manufacturer's calibration.
我们提出了一种同时校准两个彩色相机、一个深度相机以及它们之间相对姿态的算法。该方法旨在具有三个关键特性:准确、实用、适用于广泛的传感器。该方法仅需要一个平面从各种角度成像。校准不使用深度图像中的深度不连续,从而使其对噪声具有灵活性和鲁棒性。我们将这种校准应用于 Kinect 设备,并提出了一种新的深度传感器失真模型。我们进行的实验表明,与制造商的校准相比,精度有所提高。
