摘要：3D scanning using laser scanners has been recognized as one of the most efficient and accurate way to record and reconstruct digitally large-scale cultural heritages. The authors report on 3D scanning survey of Roman monuments and remains in Tyre, Lebanon, which was conducted in September 2002, and on succeeded digital reconstruction and visualization of those monuments. During limited period of time for the survey, many Roman monuments and remains were scanned including the memorial gate on the paved road aligned by columns, a sarcophagus, and a stepped stand of the Hippodrome in Albaas area, as well as the whole excavation field in Ramali area and the interior space of underground tomb within the field, resulted in many sets of point cloud data. For 3D scanning, the authors combined two different types of laser scanners, one with coarser resolution with faster scanning speed and coverage, and the other with finer resolution with slower scanning speed. The former was mainly used to determine the location of individual remains or structures, while the latter was used to record the details of the monuments. By combining both scanners, larger areas were covered efficiently, while recording the details of important monuments. Then the data were automatically aligned and merged with a software, and the resulted polygon data were mapped with textures using digital photos obtained at the time of laser scanning. Finally, CG animation of those remains has been produced for providing photo-realistic spatial image of the remains to those who have never visited the place
