Development of Object Detection Technology Using Laser Sensor for Intelligent Excavation Work

The demand for the development of intelligent construction equipments is increasing gradually to deal with the current problems of construction technology such as lack of skilled workers, aging of engineers, safety issues, etc. Especially, earth work such as excavation is very machine-dependent, and there have been many researches on the development of intelligent excavator. This requires a great safety concern. Thus, the objective of this study is to develop the technology of enhancing the safety of intelligent excavation system by developing the essential technology of object detection for the intelligent excavator and applying it to a user-friendly system. Literature was reviewed, and the function of various sensor technologies was investigated and analyzed. Then, the best laser sensor was selected for an experiment to determine its effectiveness. Object detection algorithm was developed for a user interface program, and this can be used as the fundamental technology for the development of a safety management system for intelligent excavation work.
