Measuring Sloping Floor of Heritage Building Using Point Cloud Data from LiDAR Survey

Abstract Heritage building restoration and preservation work relies heavily on a thorough inspection of condition survey. One the dilapidations that may occur in heritage building, is sloping floor defect where uneven, or slanting towards specific direction. In this case study, was identified at Ipoh Town Hall, Perak which require further investigation. Using conventional methods to survey surveying will more time manpower. Instead, paper explores LiDAR scanning measure identify defects. R programming techniques are applied analyse point cloud results from assess greater detail.
