Abstract: Abstract With the advantage of efficiently obtaining high-precision data, Terrestrial Laser Scanning (TLS) has been increasingly applied in indoor wall measurement. However, the current quantity approach still depends on manual manipulation, and the existing use of TLS technology to assist wall flatness measurement also has limitations, which result in its inability to be fully utilized. Therefore, this study proposed a new method of wall flatness measurement that combines the advantages of TLS technology, which allows high-precision data collection, and the point cloud processing, which enables fast and efficient calculations. The proposed method also developed an algorithm that automatically removes noise inside the room and generates a wall distance deviation cloud map that can fully visualize the wall flatness information. To illustrate the proposed method, the flatness of typical building walls is tested and compared with the data manually measured by experienced workers. The comparison shows that the proposed method can efficiently measure the flatness of indoor wall with high accuracy.
