基于ＯｐｅｎＣＶ的车辆轮廓检测为了获得理想的车辆轮廓线，提出了一种基于开源计算机视觉库ＯｐｅｎＣＶ的轮廓检测新方法。首先对图像迸行形态 学去噪、平滑滤波处理和二值化阈值分割等预处理，获得二值化黑白图像。然后通过轮廓提取和跟踪检测到车辆外轮廓线。 在ＶＣ＋＋６．０环境下，利用Ｏｐｅｎｅｒ编程实现了此方法。-Proposed a new method of contour detection based on open source computer vision library OpenCV OpenCV-based vehicle contour detection in order to obtain the ideal vehicle contour. First image into line morphological denoising, filtering, processing and binarization threshold segmentation pretreatment, the binary black and white images. And contour extraction and tracking of detected vehicles contour. Opener programming in VC++6.0 environment, to achieve this.
