OBJECT DETECTION DEVICE

摘要

A reflective wave of a transmission signal of an ultrasonic wave from an obstacle (100) is acquired through direct and indirect transceiving; a candidate position for the point of reflection and amplitude data of the reflective wave from the candidate position are mapped in 3D, on the basis of propagation distance data for the transceiving of the ultrasonic wave signal and of amplitude data of the reflective wave, on a detection area of a distance sensor group (Sgn); and a position and shape of the obstacle (100) are determined and displayed on the basis of the 3-D mapping data.
