In the construction industry, Construction based on precast concrete elements is attracting attention due to its various advantages. However, despite the many advantages of precast concrete elements, if quality control of precast concrete elements is not reliably performed, great loss will occur. In order to prevent this problem, many studies have recently been conducted on a system for measuring the dimension of precast concrete elements using a 3D laser scanner for quality control. However, there is a lack of studies that apply algorithms to the absence of real-size precast concrete elements. Therefore, the purpose of this study is to evaluate the performance of the algorithm based on the actual size precast concrete elements. Dimension measurement algorithm proceeds in the order of data acquisition, data preprocessing, mirror plane extraction and matching, edge line and corner point extraction, and measurement error evaluation. As a result of the experiment, measurement errors of 3 to 4 mm in the top surface of the precast concrete slab and 10 to 15 mm in the side surface were obtained.
