Chinese Ancient Architecture Image Database

The following datasets are currently available for non-commercial use. The datasets have two parts, one part consists of laser scan data and corresponding image data which used to compare the accuracy and completeness with the different reconstruction methods, the other consists of the image collections of the typical ancient architectures in the four Buddhist mountains (Mount Wutai, Mount Emei, Mount Jiuhua, Mount Putuo) and two Taoist mountains (Mount Wudang, Mount Qingcheng).Benchmark DatabaseWe use the Riegl-LMS-Z420i laser scanner to scan the 3 buildings in the Tsinghua University. The scanner’s accuracy is 10mm@50m, and the angular stepwidth is 0.0057degree. The 3 buildings are the old gate, the tsinghua school, and the life science building. You can download the groundtruth data from laser scanner, the image data and the camera projection matrix of each buildings. And you can also obtain the evaluation software which is used to evaluate the difference between your result and the groundtruth in Software section.Ancient Architecture Image DatabaseWe have captured typical ancient architectures in the four Buddhist mountains (Mount Wutai, Mount Emei, Mount Jiuhua, Mount Putuo) and two Taoist mountains (Mount Wudang, Mount Qingcheng). The camera is Canno EOS 5D.

当前可获取以下非商业使用的数据集。该数据集包含两个部分：其一为激光扫描数据与配套图像数据，用于对比不同重建方法的精度与完整性；其二为四大佛教名山（五台山、峨眉山、九华山、普陀山）与两座道教名山（武当山、青城山）的典型古建筑影像集。

基准数据库：我们采用Riegl-LMS-Z420i激光扫描仪（Riegl-LMS-Z420i laser scanner）对清华大学内的3栋建筑开展扫描作业。该扫描仪的测量精度为10mm@50m，角步距为0.0057°。这3栋建筑分别为老校门、清华学堂与生命科学楼。用户可下载各建筑的激光扫描真值数据、图像数据以及相机投影矩阵，此外还可在软件板块获取用于评估重建结果与真值之间差异的评测软件。

古建筑影像数据库：我们采集了四大佛教名山（五台山、峨眉山、九华山、普陀山）与两座道教名山（武当山、青城山）的典型古建筑影像。所用相机为佳能EOS 5D（Canon EOS 5D）。
