Road sign recognition device reduces image data to simplified representation by erasing regions containing class-specific attribute data

摘要

The device includes a digital image sensor and a processor which determines if the image contains road signs. Its memory contains a classifier which is generated from a representative sample of attribute data. The processor extracts real attribute data from image data determined to be a road sign, and classifies them using the classifier. The device includes a digital image sensor and a processor which determines if the image contains road signs. A memory contains a classifier which is generated from a representative sample of attribute data. The processor extracts real attribute data from image data determined to be a road sign, and classifies them using the classifier. The image data are separated into regions containing class-specific attribute data and regions containing sign-specific attribute data. The processor reduces the data to a simplified representation by erasing image regions containing class-specific attribute data, and replacing them with simplified representations of the class-specific attribute data of the class assigned to the road sign. A display displays the simplified road sign. A method of recognizing road signs is also claimed. Also claimed is the use of the device for reminding the driver of a vehicle.
