| 摘 要： | 首先利用道路边界信息限定车辆的存在范围,以提高识别的实时性.接着根据灰度图像上车辆底部的灰度特征、方差特征和下边界梯度特征构造车辆检测目标函数,以指导在车辆存在区检测前方车辆.最后利用区域增长方法剔除由噪声引起的误判.实验验证表明,在复杂环境下该目标函数能够有效地消除大量无规则噪声的影响,并能准确地识别出车辆目标.

| Abstract: | Firstly the presence area of vehicles is confined by road boundary information for improving the real-timeliness of identification.Then based on the features of grayscale,variance and lower edge gradient at the bottom of vehicle in a monochromatic image,the objective function for vehicle detection is constructed as a guide to detect front vehicles in their presence area.Finally some misjudgments caused by noises are rejected with the method of region-growing.Test verification shows that in complex condition... |
