Real-time detection of hazardous driving

摘要

A system is disclosed which provides real-time detection of hazardous driving behavior. The system collects information about the motion of a vehicle along a path, for example, using a global positioning satellite system receiver. Roadside signs along the path are detected and their content determined. That information is compared with information about the motion of the vehicle to provide information with regard to potentially hazardous driving behavior.

主权项

1. A method for real-time detection of hazardous driving comprising:
collecting first data about driver control signals applied to a vehicle moving along a path; collecting second data about the motion of the vehicle along the path; detecting roadside signs along the path as the vehicle moves toward them, by:
scanning the roadside along the path to detect roadside signs;capturing images of the roadside; andprocessing the captured images to identify roadside signs based on size and shape of the roadside signs; determining content of the roadside signs detected along the path; comparing the detected content of the roadside signs with the driver control signals and the motion of the vehicle; and in response to the step of comparing, providing information with regard to the operation of the vehicle.
