The as-built construction scenes can be represented in the format of the 3D point cloud by photogrammetry technique, enabling automated construction progress monitoring. To reduce the manual efforts in gathering visual data, the unmanned ground vehicle (UGV) has been recently introduced to autonomously navigate on-site and collect relevant data at...

... at 200. They were used as potential waypoints and needed to be further selected for UGV to conduct the visual data collection. At the randomly generated nodes, the rotation of the camera was set at intervals of 30 degrees to capture the BIM color and depth image as the preview results so that 12 images would be taken at each node. For example, Fig. 4 shows a sample of preview color and depth image on BIM. Elements were represented with distinct colors for computing coverage and resolution. One significant factor considered in this study is the level of progress criticality in the POWS method when designing the UGV data collection mission. The criticality can be represented by the ...
