Construction Site Evaluation Employing 3D Models from UAV Imagery
Conference: Publication Date: 26 March 2018Testing Method:
Continuous monitoring of construction stages using traditional methods such as survey measurement is a laborintensive process. With the advancements in Unmanned Aerial Vehicles (UAV) and image processing techniques, monitoring procedures can be improved.
First, various flight parameters, mission planning applications and cameras for capturing aerial images will be compared. Second, the procedure for post-processing aerial images to create 3D models and orthomosaics will be reviewed including the impact of different ground sampling distances on the quality of the 3D models. Optimized 3D models will be analyzed further to achieve accurate measurements (length measurement and volume measurement). Finally, the effects of inclusion of manually surveyed ground control points on the final measurements will be reviewed and the accuracy of the measurements will be compared against manual and survey measurements.
