摘要
基于红外图像的视觉处理,提出了新的汽车夜视安全控制方法。通过对车载热像仪所拍摄的红外图像的一系列处理,包括图像滤噪、图像分割和图像分析,得到前方车辆的排气管的形心坐标。根据这个坐标和已知的参数,建立测距几何模型,可以实时得到本车与前车的距离。指出将这一控制识别方法可以用在汽车防撞系统中,具有一定的应用前景。
A new control method is presented.It is used on the vehicle ' s night-vision safety based on the processing of infrared images which are taken by thermal infrared imager on the vehicle. After a series of image processings including denoising, segmentation and analysis , the centroid of the front exhaust pipe is detected. The geometrical model of distance measurement is built on the basis of the centroid and other known parameters . It's indicated that this control method could be applied to the automotive anti-collision system and open the door widely for increased application.
