Abstract:
1. A vehicle identification system provides to identifying a plurality of vehicle body of vehicles to confirm an identity of the plurality of vehicles, the vehicle identification system includes: a vehicle database, storing a plurality of vehicle body image of vehicles; a model database, connecting to the vehicle database, the model database retrieving the vehicle body image from the vehicle database and through an algorithm to calculate the vehicle body image and a reference image to get a first feature point set and a second feature point set, and compare with the first feature point set and the second feature point set, the reference image calibrating each vehicle body image, and establishing a plurality of vehicle model images with a chamfer distance transform; an image capture unit, capturing a real-time vehicle body image of each vehicle, the image capture unit through the algorithm calculates the real-time vehicle body image and the reference image to get the third feature point set and the second feature point set, the reference image calibrating the real-time vehicle body image; and a process unit, connecting to the model database and the image capture unit, the process unit calculating the real-time base body image gradient for each pixel in each image with the plurality of vehicle models in a plurality of product between the gradient of each pixel of the substrate, and selecting a maximum value within the plurality of product to determine the real-time vehicle body image corresponding to one of the vehicle model images.
