1.acquire 3-D point cloud data directly by vehicular laser scanning

2.acquire airborne video or remote sensing(aerial) images

3.fuse multi-source data

4.reconstruct large scale scenes with high-precision

Here we show our tree reconstruction technique presented in Siggraph Asia 2010.

Here we show a semi-automatic and efficient method for producing full polygonal models of range scanned trees, which are initially represented as sparse point clouds.

Here we show the points cloud and 3D model of SIAT, the model is gengerated from the points.

Here we show the Scanning Of A Tunnel, the bottom part is the vedio got by camera and the top part is the point cloud got by sanner.

Here we show the scanning and 3D model of highway named Nanping in Shenzhen, the model is got from the point cloud.

Here we show the 3D model of a city.
