Reconstructing a textured CAD model of an urban environment using vehicle-borne laser range scanners and line cameras

Huijing Zhao, Ryosuke Shibasaki
2003 Machine Vision and Applications  
The texture of the urban features is generated by projecting and resampling line images onto the geometric model.  ...  A geometric model is first generated using the geo-referenced laser range data, where urban features, such as buildings, ground surfaces, and trees are extracted in a hierarchical way.  ...  First, in data acquisition, successive range views have to keep a degree of overlay so that location and direction of view points can be traced (or refined) by registering range data.  ...
