A passive infra-red guidance system and method for augmenting operation of an autonomous vehicle on a roadway includes at least one forward-looking infra-red imaging sensor mounted on the vehicle in operative communication with an image processor tied into the vehicle's operational system. The system determines the left and right edges of the roadway using thermal imaging, and then determines thecenterline of the travel lane in which the vehicle is travelling based on the determined left and right edges of the roadway. The system then compares the determined centerline of the travel lane withthe actual position of the vehicle and identifies any adjustment needed for the vehicle's position based on the comparison. The left and right edge determination may comprise identifying a differencebetween a thermal signature representative of the roadway and a thermal signature representative of a non-roadway portion that is located proximate to the roadway portion.

    一种被动红外线引导系统和方法,其用于增强自动驾驶车辆在道路上的操作的,包含至少一个安装在车辆上的前视红外线成像传感器,其与车辆操作系统绑定的图像处理器进行有效通信。所述系统使用热成像判定道路的左右边缘,然后根据所判定的道路左右边缘,判定车辆行驶所在的行车道的中心线。然后系统会将所判定的行车道中心线与车辆的实际位置进行比较,并根据比较结果决定车辆位置所需的任何调整。左边缘和右边缘判定可以包括辨识代表道路的热特征和代表非道路部分的热特征之间的差异,非道路部分紧邻的道路部分。
