Abstract:
1. A vehicle circumferential image providing device configured to provide an image at a circumference of a vehicle to a driver, the vehicle circumferential image providing device comprising: a plurality of imaging units configured to image the circumference of the vehicle, wherein the plurality of imaging units are configured to image in mutually different directions; a first image processing unit configured to coordinate convert images at the circumference of the vehicle imaged by the plurality of imaging units using a ground surface as a reference surface, and generate an overhead image by combining the coordinate-converted images; an edge detecting unit configured to detect edges in the overhead image generated by the first image processing unit; a determining unit configured to determine continuity of edge lines extending over connected parts of the coordinate-converted images, among edge lines detected by the edge detecting unit; and a second image processing unit configured to perform imaging processing by setting edge lines at a far side of the vehicle to match edge lines at a near side of the vehicle, thereby setting the edge lines to be continuous at the connected parts, when the edge lines extending over the connected parts of the coordinate-converted images are discontinuous.
