| 摘 要： | 提出了一种新的车型识别技术.该技术分成两大部分,第一部分是如何准确地测量车辆的三维信息.首先需要从一系列图象中准确检测出车辆,然后从背景中将车辆完整的分割出来,再使用一个简单的透视变形模型,完成从二维信息到三维信息的转换,获得车辆的长度、宽度和高度特征.第二部分是将这些特征输入一个SVM分类器进行识别处理.实验证明,该方法在车型识别中,具有比较高的识别精度.

| Abstract: | Presents a new technology for vehicle type identification.This first part is how to get the three-dimensional characters of vehicle from image.First get the vehicle in sequences image and extract the vehicle from background.Then,we transform the two-dimensional image to three-dimensional image with a simple projection model for getting the real length and width of vehicle.At last we input these characters into a SVM classifier.This method have the more precision compared with other methods. |

| Keywords: | image processing projection model three-dimensional characters SVM |
