Patent Images
1. An apparatus for displaying a bird'"'"'s eye view image, comprising:
- a plurality of on-vehicle cameras photographing surrounding objects of a vehicle;
an image-converting means for processing images obtained by the on-vehicle cameras, the image-converting means including means for correcting lens distortion in each of images photographed by the on-vehicle cameras, means for converting a view point, means for trimming display areas, and means for synthesizing a bird'"'"'s eye view image around the vehicle by connecting the trimmed display areas; and
an on-vehicle display unit displaying the synthesized bird'"'"'s eye view image to a driver or an occupant,wherein the image-converting means further includes a reference height-converting means, which is required to produce first through n+1TH bird'"'"'s eye view images by sequentially drawing the second through n+1TH bird'"'"'s eye view images for second through n+1TH reference heights, which are sequentially higher than ground level indicated by a first reference height, where n is an integer greater than 0, in addition to drawing the bird'"'"'s eye view image for the ground level.
