Method and System for Collecting Information Relating to Identity Parameters of A Vehicle
First Claim
1. A computer-implemented method for identifying a vehicle, the method comprising:
- obtaining one or more images of the vehicle;
producing at least one sub-image, the at least one sub-image comprising an area of the one or more obtained images that contains one or more identity parameters of the vehicle, the at least one sub-image being enhanced based on the one or more obtained images;
detecting one or more interest points within the at least one sub-image, each interest point relating to at least one of the one or more identity parameters, and each interest point being substantially capable of detection as an interest point across a plurality of chan ing image capture conditions;
for each distinct interest point, processing the at least one sub-image to obtain one or more descriptors, the one or more descriptors comprising a corresponding numeric representation of the distinct interest point;
matching, with one or more processors, one or more of the descriptors to one or more templates, each template corresponding to at least one of (a) a known vehicle manufacturer and (b) a known vehicle make and each template comprising one or more predetermined descriptors representing interest points in previously obtained images that correspond to known identity parameters;
calculating a confidence measure of a match between one or more of the descriptors and one or more of the templates; and
identifying one or more identity parameters of the vehicle based on at least one match and at least one confidence measure.

Abstract
The present invention discloses methods and systems for collecting information relating to identity parameters of a vehicle. According to the invention an image of the vehicle is obtained. A sub-image within the image is identified, interest points within the sub-image are detected and the sub-image is processed so as to obtain descriptors representing the interest points. The descriptors are matched to predetermined descriptors representing interest points in previously obtained images respective of known identity parameters and the information is stored in a record representing an identity of the vehicle.

12. A system for identifying a vehicle, the system comprising one or more processors configured to interact with a computer-readable medium in order to perform operations comprising:
-
obtaining one or more images of the vehicle; producing at least one sub-image, the at least one sub-image comprising an area of the one or more obtained images that contains one or more identity parameters of the vehicle, the at least one sub-image being enhanced based on the one or more obtained images; detecting one or more interest points within the at least one sub-image, each interest point relating to at least one of the one or more identity parameters, and each interest point being substantially capable of detection as an interest point across a plurality of changing image capture conditions; for each distinct interest point, processing the at least one sub-image to obtain one or more descriptors, the one or more descriptors comprising a corresponding numeric representation of the distinct interest point; matching, with one or more processors, one or more of the descriptors to one or more templates, each template corresponding to at least one of (a) a known vehicle manufacturer and (b) a known vehicle make and each template comprising one or more predetermined descriptors representing interest points in previously obtained images that correspond to known identity parameters; calculating a confidence measure of a match between one or more of the descriptors and one or more of the templates; and identifying one or more identity parameters of the vehicle based on at least one match and at least one confidence measure. - View Dependent Claims (14)

15. A computer storage medium encoded with a computer program, the program comprising instructions that when executed by a data processing apparatus cause the data processing apparatus to perform operations comprising:
-
obtaining one or more images of the vehicle; producing at least one sub-image, the at least one sub-image comprising an area of the one or more obtained images that contains one or more identity parameters of the vehicle, the at least one sub-image being enhanced based on the one or more obtained images; detecting one or more interest points within the at least one sub-image, each interest point relating to at least one of the one or more identity parameters, and each interest point being substantially capable of detection as an interest point across a plurality of changing image capture conditions; for each distinct interest point, processing the at least one sub-image to obtain one or more descriptors, the one or more descriptors comprising a corresponding numeric representation of the distinct interest point; matching, with one or more processors, one or more of the descriptors to one or more templates, each template corresponding to at least one of (a) a known vehicle manufacturer and (b) a known vehicle make and each template comprising one or more predetermined descriptors representing interest points in previously obtained images that correspond to known identity parameters; calculating a confidence measure of a match between one or more of the descriptors and one or more of the templates; and identifying one or more identity parameters of the vehicle based on at least one match and at least one confidence measure. - View Dependent Claims (16)
