Taken Riegl LMS Z420i for instance, the site design of laser radar station and reflective pieces was introduced. Then, laser radar data and digital photo registration, data acquisition, data processing was given. After that, two method of 3D modeling were stated, one used the modeling method of 3D modeling software Phidias based on MicroStation; the other based on triangular mesh. At last, it took pottery house from Hepu Han tomb as an example, 3D model of pottery house was come true. The result showed, rule model reflect the structure and proportion of the pottery house well, but irregular model reflect the status of pottery house.
