Precise 3D indoor models play an important role in applications ,such as ancient heritage protection ,meticulous management of public places and indoor navigation .The LiDAR has been gradually applied to the interior 3D reconstruction .In this paper ,high‐precision indoor point cloud data with CCD image color information is firstly obtained by means of mobile LiDAR .Then ,a complete technique process for indoor elements’ three‐dimensional reconstruction is proposed .Finally ,based on the proposed process , interior three‐dimensional model with high‐precision coordinates is realized on three‐dimensional modeling platform such as Autodesk CAD .The experimental results show that mobile LiDAR can be applied to high‐precision indoor 3D point cloud data’s acquisition .Moreover ,the technique process proposed is in favor of indoor whole elements’ true three‐dimensional reconstruction in real size and texture .
