Abstract:

The novel view synthesis for traditional sparse light field camera arrays generally relies on an accurate depth approximation for a scene. To this end, it is preferable for such camera-array systems to integrate multiple depth cameras (e.g. Kinect V2), thereby requiring a precise registration for the integrated depth sensors. Methods based on special calibration objects have been proposed to solve the multi-Kinect V2 registration problem by using the prebuilt geometric relationships of several easily-detectable common point pairs. However, for registration tasks incapable of knowing these precise geometric relationships, this kind of method is prone to fail. To overcome this limitation, a novel Kinect V2 registration approach in a coarse-to-fine framework is proposed in this paper. Specifically, both local color and geometry information is extracted directly from a static scene to recover a rigid transformation from one Kinect V2 to the other. Besides, a 3D convolutional neural network (ConvNet), i.e. 3DMatch, is utilized to describe local geometries. Experimental results show that the proposed Kinect V2 registration method using both color and deep geometry descriptors outperforms the other coarse-to-fine baseline approaches.
