英文摘要	In this paper, a marked point process based method is used to extract buildings from airborne LIDAR data. At first, a Gibbs energy model is build according to the geometric feature of the object in the point cloud data. This model contains both a data coherence term which fits the objects to the data and a prior term which incorporates the prior knowledge of the object geometric properties. Then the previously defined model is optimized by the RJMCMC (Reverse Jump Markov Chain Monte Carlo) algorithm and simulated annealing algorithm. Finally, fine processing removes the terrestrial points, noise points and tree crown points of the extracted objects which are mistakenly extracted as buildings, while combining adjacent objects. The method was tested with three different aerial LiDAR data sets from ISPRS. The results show that our method is capable of efficient and robust building extraction.
