中文摘要：

为了让智能车获取更为准确的道路信息，提出采用中值滤波对图像进行降噪处理，在一定的条件下可有效地克服线性滤波器所带来的图像细节模糊，对滤除脉冲干扰及图像扫描噪声最为有效。实验证明，中值滤波在智能车图像处理中具有很好的降噪效果。

英文摘要：

To obtain more accurate road infor-mation,the median filtering method is used in im-age noise reduction.Under certain conditions,the median filtering can effectively avoid the fuzzy phe-nomena of image detail in linear filter.It is the most effective method to filter out pulse interference and image scanning noise.Experiment resultsprove that median filtering in the intelligent car hasa good noise reduction effect in image processing.
