1. A system for determining a range of a vehicle, the system comprising:
- a camera configured to view a region of interest including the vehicle and generate an electrical image of the region;
a processor in electrical communication with the camera to receive the electrical image, wherein the processor is configured to perform a pattern matching algorithm to identify the vehicle, and wherein the processor is configured to perform a vehicle identification algorithm to identify the vehicle and construct the template for the pattern matching algorithm based on the vehicle identification algorithm; and
wherein the processor is configured to apply the pattern matching algorithm when the first algorithm produces a vehicle identity score below a score threshold.

Abstract
A system for determining range and lateral position of a vehicle is provided. The system includes a camera and a processor. The camera is configured to view a region of interest, including the vehicle, and generate an electrical image of the region. The processor is in electrical communication with the camera to receive the electrical image and analyzes the image by performing a pattern matching algorithm on the electrical image, based on a template. A score is determined based on the algorithm indicating the likelihood that certain characteristics of the electrical image actually correspond to the vehicle.

18. A method for determining a range of a vehicle, the method comprising:
-
performing a first algorithm to identify the vehicle constructing a template for a pattern matching algorithm based on the first algorithm; storing the template for use with subsequent images; generating an electrical image of a region including the vehicle; and performing the pattern matching algorithm to identify the vehicles; constructing a plurality of objects based on characteristics of the electrical image indicative of potential vehicle locations; calculating a score for each object of the plurality of objects; and wherein the step of performing the pattern matching algorithm is performed when the score for each object of the plurality of objects is lower than a score threshold.
