Title:
VEHICLE EXTERIOR RECOGNITION DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/065970
Kind Code:
A1
Abstract:
The present invention addresses the problem of acquiring a vehicle exterior recognition device that is able to improve the accuracy of a distance measurement method based on feature point tracking of a camera image. An on-vehicle exterior recognition device according to the present invention extracts a feature point from an image including the environment around a vehicle, measures a three-dimensional position of the feature point on the basis of movement in the image obtained by time-series tracking for the feature point, and calculates a footing position on the image from the three-dimensional position of the feature point. Then, the on-vehicle exterior recognition device extracts, from within the image, a road surface area in which the vehicle can travel by use of similarity in texture of the image, and determines that the feature point, for which the footing position of the feature point is determined not to be included in the road surface area, is highly reliable.
