Scene understanding device
First Claim
1. A scene understanding device that determines a degree of risk at a specific spot where a vehicle would otherwise bump into a vehicle or a pedestrian caused by crossed roads, comprising a computer programmed to:
- obtain map data, on a scheduled traveling route, of a plurality of obstacle detection frames for detecting an obstacle, the plurality of obstacle detection frames set for both of the crossed roads in advance;
obtain route data on the scheduled traveling route of a host vehicle;
select a part of the obstacle detection frames to be determined depending on the scheduled traveling route from the plurality of obstacle detection frames set for the specific spot in advance;
determine whether there exists an obstacle in the selected part of the obstacle detection frames; and
calculate the degree of risk at the specific spot based on a result of determining whether an obstacle exists there.

Abstract
A scene understanding device obtains map data where one, two or more obstacle detection frames, shaped corresponding to a road structure, for detecting an obstacle are set in advance for a specific spot on a road where a vehicle would otherwise bump into a vehicle or a pedestrian. The scene understanding device determines whether there exists an obstacle in the obstacle detection frames set for the specific spot on a scheduled traveling route of a host vehicle, and calculates the degree of risk at the specific spot based on a result of determining whether there exists an obstacle therein.
