Title:
IMAGE PROCESSING DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/090170
Kind Code:
A1
Abstract:
Provided is an image processing device that is capable of: storing three-dimensional information relating to a road surface (3D road surface information); transforming/converting the stored 3D road surface information into the current time by using the motion of a vehicle; using the three-dimensional information from the road surface together with a monocular-based distance estimation process; and increasing distance measurement accuracy without a special sensor being necessary while maintaining obstacle detection accuracy. In particular, the image processing device is capable of providing support in a case where an automobile is turning at an intersection potentially containing a pedestrian area (in other words, containing a difference in ground height relative to the roadway area) that requires accurate monocular-based distance measurement for a detection object. Used are: a monocular-based distance estimation process carried out by an obstacle ranging unit 161; and 3D road surface information that has been stored via a 3D road surface information acquisition unit 131 and converted to the current time by a 3D road surface information management unit 141.
