Automatic Registration Of Fused Lidar/Digital Imagery (Texel Images) For Three-Dimensional Image Creation, Scott E. Budge, Neeraj S. Badamikar, Xuan Xie

Electrical and Computer Engineering Faculty Publications

Several photogrammetry-based methods have been proposed that the derive three-dimensional (3-D) information from digital images from different perspectives, and lidar-based methods have been proposed that merge lidar point clouds and texture the merged point clouds with digital imagery. Image registration alone has difficulty with smooth regions with low contrast, whereas point cloud merging alone has difficulty with outliers and a lack of proper convergence in the merging process. This paper presents a method to create 3-D images that uses the unique properties of texel images (pixel-fused lidar and digital imagery) to improve the quality and robustness of fused 3-D images. …
