During the building construction, contractors are required to measure the completed form and calculate the quantity and are increasingly employing point cloud data for this purpose. Using point cloud data is expected to perform higher productivity than the conventional manual measurement and taking pictures. This paper proposes a new pile center measurement method using point cloud data obtained by Structure from Motion (SfM) and Building Information Modeling (BIM). The efficiency, cost, and accuracy of the proposed a pproach were investigated compared to the conventional surveying method.
