Fusion of Stereo Vision and Time-of-Flight Imaging for Improved 3D Estimation

Fusion of Stereo Vision and Time-of-Flight Imaging for Improved 3D Estimation

Abstract	In this paper the fusion of two 3D estimation techniques is suggested: Stereo vision and Time-of-Flight (TOF) imaging. By converting the TOF-depth measurements to stereo disparities the correspondence between images from a fast TOF-camera and standard high resolution camera pair are found so the TOF depth measurements can be linked to the image pairs. Also in the same framework a method is developed to initialize and constrain a hierarchical stereo matching algorithm. It is shown that in this way higher spatial resolution is obtained than by only using the TOF camera and higher quality dense stereo disparity maps are the results of this sensor fusion.
