DRIVING ASSISTANCE SYSTEM AND DRIVING ASSISTANCE METHOD FOR VEHICLE

摘要

This invention provides a driving assistance system for a vehicle, with which an intersection having poor visibility can be detected with a high degree of precision and a driver can be alerted thereto while suppressing cost and time requirements. A sample determination unit identifies an image captured by a front camera as detection subject sample data relating to an intersection having poor visibility when the detection subject is detected by a stereo camera, a distance calculation unit, and a first object detection unit but the detection subject is not detected in a position of the detected detection subject by the front camera and a second object detection unit, and identifies the image captured by the front camera as non-detection subject sample data when the detection subject is detected in the position of the detected detection subject by the front camera and the second object detection unit.

主权项

1. A driving assistance system for a vehicle, comprising:
a stereo camera that captures an image of a view of a rear of the vehicle; a distance calculator that calculates a distance to a detection subject captured by the stereo camera; a first object detector that detects a direction of the detection subject captured by the stereo camera; a high-precision indicator that measures coordinates of the vehicle; a front camera that captures an image of a view of a front of the vehicle; a second object detector that detects a direction of the detection subject captured by the front camera; and a sample determiner that identifies the image captured by the front camera as detection subject sample data relating to an intersection having poor visibility when the detection subject is detected by the stereo camera, the distance calculator, and the first object detector but the detection subject is not detected in a position of the detected detection subject by the front camera and the second object detector, and identifies the image captured by the front camera as non-detection subject sample data when the detection subject is detected by the stereo camera, the distance calculator, and the first object detector and the detection subject is detected in the position of the detected detection subject by the front camera and the second object detector.
