VEHICLE HEADLIGHT DETECTING METHOD AND APPARATUS, AND REGION-OF-INTEREST SEGMENTING METHOD AND APPARATUS

摘要

A method and apparatus for detecting vehicle headlights and a region-of-interest (ROI) segmenting method and apparatus are disclosed. The ROI segmenting method includes: performing an edge extracting operation on a captured image to obtain edges of the captured image; selecting edges meeting predetermined criteria from the obtained edges, the predetermined criteria being the similarity between the region surrounded by the selected edges and the pattern formed by a vehicle headlight in physical reality at a position of the selected edges; determining the region surrounded by the selected edges within the captured image as a vehicle headlight pattern; and segmenting the ROI which potentially includes the vehicle pattern from the captured image based on the determined vehicle headlight pattern. With such a method and apparatus, the ROI of a vehicle may be acquired from the image without using the vehicle's bottom shadow.
