BIRD'S-EYE-VIEW VIDEO IMAGE GENERATION DEVICE, BIRD'S-EYE-VIEW VIDEO IMAGE GENERATION SYSTEM, BIRD'S-EYE-VIEW VIDEO IMAGE GENERATION METHOD, AND PROGRAM

摘要

The present invention is provided with: a video image data acquisition unit 42 for acquiring video images from a plurality of cameras for photographing to the front, rear, left, and right of a vehicle; an obstacle information acquisition unit 43 for acquiring information from a sensor group 20 for detecting obstacles around the vehicle; a bird's-eye-view video image generation unit 45 for performing a viewpoint conversion process on the video images acquired by the video image data acquisition unit 42 to synthesize the video images, whereby a bird's-eye-view video image as if viewed from above the vehicle is generated, and when the obstacle information acquisition unit 43 has detected an obstacle, the bird's-eye-view video image generation unit 45 reduces the display area in the bird's-eye-view video image from any direction differing from the direction in which the obstacle was detected, and generates a video image in which the display range is expanded in the direction in which the obstacle was detected; and a display control unit 48 for displaying on a display panel 30 the video image generated by the bird's-eye-view video image generation unit 45.
