4D Point Cloud (4DPC)-driven real-time monitoring of construction mobile cranes

However, the existing sensing or monitoring methods have limitations in mobile cranes on sites. Recently, advent of 4D point cloud (4DPC) technology with a unique spatial-temporal data structure has shown potential. In this paper, we present 4DPC approach, which includes set prototype devices and rule-based object detection method. A proof-of-concept test to monitored hoisting process two H-beams footbridge construction project. The method successfully detected target beams collected six-hour data.
