PASSENGER VEHICLE MAKE AND MODEL RECOGNITION SYSTEM
First Claim
Patent Images
1. A system for recognizing a passenger vehicle make and model, the system comprising:
- a make and model recognition (MMR) database, which is constructed from rear view videos of passenger vehicles;
a universal view, which is generated from the make and model recognition database by averaging images from the make and model recognition database, and wherein images generated are identified as “
UVaMMRDB”
;
a showcase view, which represent visually distinct types of vehicles, and wherein copies of the images aligned to their type specific showcase view and stored in the MMR database, and wherein the images are identified as “
SVaMMRDB”
;
a moving object detection system, which is configured to detect region of interest (ROI) of passenger vehicles for classification, and the ROI is registered with the universal view, which aligns landmarks in the ROI, the aligned ROI is identified as the universal view aligned ROI (“
UVaROI”
);
after illumination normalization, the UVaROI is compared to UVaMMRDB to find the nearest neighbors in the MMR database, and based on the nearest neighbors a type is assigned to the ROI, and the ROI is registered with the showcase view of the type to which it is assigned to and the registration process aligns landmarks in the ROI and the showcase view, and the showcase view aligned ROI is identified as “
SVaROI”
; and
wherein after illumination normalization, the SVaROI is compared to SVaMMRDB to find the nearest neighbors in the MMR database, and based on these neighbors a make and model is assigned to the ROI.
