METHOD OF PREDETERMINED ROAD OBJECT RECOGNITION IN IMAGES AND VEHICLE DRIVING ASSISTANCE DEVICE

摘要

The invention relates to a method of predetermined road object recognition in images, including : - a first stage of detection (101), to detect predetermined road object-like regions in images, done by sliding a search window through an image and checking whether an image region is classified as said predetermined road object or non-predetermined road object, and - a second stage of validation (102), to classify said predetermined road object-like regions into predetermined road objects and non- predetermined road objects, characterized in that in said second stage of validation (102), first descriptors computed inside said predetermined road object-like region from extracting features based on histogram of oriented gradients (HOG), and second descriptors from a Fourier-Mellin transformation (FMT) on the predetermined road object-like region pixels, supplies both a classifier to classify said predetermined road object-like regions into predetermined road objects and non-predetermined road objects. The invention also relates to a vehicle driving assistance device to implement said method of predetermined road object recognition.
