OBSTACLE DETECTION DEVICE

摘要

An obstacle detection device includes: an obstacle detection section (11) for successively emitting a beam having a predetermined spread angle to a plurality of different directions and receiving a reflected wave from an obstacle in each of the directions, thereby detecting an obstacle existing in the beam emission angle range of each direction; a distance calculation section (12) for calculating a value representing a distance between an obstacle in each direction and an automobile having the obstacle detection device according to the reception signal of reflected wave in each direction output from the obstacle detection section; an obstacle image creation section (14) for treating the distance for each direction calculated by the distance calculation section, as an image creation reference, thereby creating as an obstacle image a graphic spread in two-dimensional way in the emission angle range of the beam emitted in each direction, and creating and outputting image data for displaying the obstacle image; and a display section (15) for receiving image data created by the obstacle image creation section and displaying an image showing the positional relationship between the obstacle and the automobile.
