Conventional ICT construction vehicles have been developed to improve productivity. However, the conventional ICT construction vehicles have several technical issues in cooperated operations with workers. Therefore, we focus on a methodology to keep the safety in cooperated operations with workers and construction vehicles at a construction site. Our proposed methodology is based on 3D sensing from a construction. In 3D sensing, temporal point clouds are acquired for moving object tracking. Moreover, we develop an exterior-typed 3D measurement unit with low-price RTK-GNSS and LiDAR to provide lower-price ICT construction vehicles. In this research, we experimented excavation works using a backhoe at a simulated construction space. Through the experiment, we confirmed that our methodology can detect and track the bucket and workers using temporal point clouds acquired from a backhoe in drilling works.
