Lessons Learned from Developing a 3D Point Cloud Model of a Modular House by Photogrammetric Approach
Publication: Computing in Civil Engineering 2023
ABSTRACT
There were some technical limitations, but there was an advancement in the photogrammetric approach for point cloud generation recently. Thus, the authors attempted to verify an advancement of the photogrammetric approach for the geometric quality assessment of a modular house and documented the challenges and lessons learned from developing a 3D point cloud model of an existing modular house using an existing commercially available software that uses photogrammetric approach. The documented lessons learned are: (1) obstructions by existing objects on the site; (2) insufficient overlapping of pictures; (3) low-quality GPS data; (4) movement of objects/workers; (5) different exposures; and (6) issues with combining photos taken by UAV and a handheld camera, and others. The findings will help practitioners to avoid the same mistakes/difficulties and service providers and scholars on the photogrammetric approach to conduct further research and improve the technology by resolving the raised issues.
