Abstract

Official abstract text for this publication.

An image pickup device picks-up forward images, and a GPS information acquiring section acquires satellite information that includes Doppler frequencies. A position/velocity vector computing section computes a velocity vector by using the Doppler frequencies. A locus computing section computes a locus of positions of ones own vehicle. A projected image generating section generates, from the forward images, projected images that are projected onto a road surface. A local map generating section records road surface images, that are obtained for respective points on the locus of ones own vehicle, at respective regions of a local map that is determined on the basis of a traveling direction of a moving body at each point on the locus and a set position and a posture of the image pickup device. Due thereto, a local map generating device can, by a simple structure, generate a highly accurate map.

First claim

Opening claim text (preview).

The invention claimed is: 1. A local map generating device comprising: an environment information acquiring section that is installed in a moving body, and that acquires environment information of a periphery of the moving body as seen from a set position; a projected information generating section that generates projected information by projecting a position on the environment information acquired by the environment information acquiring section on a road surface based on a set…
