Research Project:

New Approach of Extraction 3D Modeling Processing from LIDAR Data

The major contributions of this research lie in three aspects:

1) Two algorithms are developed to perform LIDAR segmentation. Compared with the algorithms proposed by other researchers these two algorithms work well in urban and suburban areas.

2) An algorithm of building boundary regularization is proposed in this study. Compared with the commonly used Minimum Description Length (MDL) algorithm, it is simple to implement and fast in computation.

3) A new method of 3D building model reconstruction from LIDAR data is developed. It is comprised of constructing surface topology, calculating corners from surface intersection, and ordering points of a roof surface in their correct sequence.
