There is an
increasing demand for an advanced safety assist device for construction




equipment that can prevent accidents in advance by detecting various blind




spots during work at construction sites. Various sensors like ultrasonic sensors,




RFID, lidar, cameras, and radar are being developed as advanced safety assist




devices used in construction equipment. Especially, radar is attractive as the




most competitive core parts because they provide the best and most reliable




performance in various adverse conditions at the construction site. However,




when the construction equipment moves, the radar mounted on the construction




equipment also has Doppler information generated from the movement by itself.




The Doppler information from motion should be removed before detecting of




targets of interest. To solve this problem, this paper proposes advanced safety




assist device based on combining an IMU(Inertial Measurement Unit) and multi-radar.




The IMU is utilized to know how tilted the direction of the sensor is. The




movement of construction equipment is measured using IMU sensors. The IMU




combined multi-radar can be used as dynamic safety assistant monitoring system




for construction heavy vehicles in a moving as well as stationary state.
