The invention provides a vehicle tunnel early warning method and device. The method comprises the following steps: determining a growth direction of tunnel boundary pixels of each first image in an image according to a morphological edge shape; determining a predicted growth position where tunnel boundary pixels of the first image reach along the growth direction; filling discontinuous positions of boundary pixels of the second image according to the shape template; and according to the matching degree between the boundary pixels, determining whether to send an instruction of turning on the vehicle lamp to the target vehicle. According to the vehicle tunnel early warning method and device provided by the embodiment of the invention, the growth position of the tunnel boundary pixel in the first image in the image is estimated through a morphological method, and the complete tunnel boundary pixel in the second image is obtained through matching and supplementing based on the tunnel shape template; and the corresponding matching degree threshold value is flexibly adjusted based on the weather condition parameters when matching early warning is carried out, so that the high-precision identification of the tunnel scene is realized, and the driving safety of the vehicle at the tunnel entrance is ensured.

    本发明提供了一种车辆隧道预警方法和装置,所述方法包括:根据形态学边缘形状确定每个第一图像的隧道边界像素在图像内的生长方向;确定第一图像的隧道边界像素沿着生长方向到达的预计生长位置;根据形状模板对第二图像的边界像素的不连续位置进行填充;根据边界像素之间的匹配度,确定是否向目标车辆发送打开车灯的指令。本发明实施例提供的车辆隧道预警方法和装置,通过形态学方法估计第一图像中隧道边界像素在图像内的生长位置,并基于隧道形状模板匹配补充得到第二图像中完整的隧道边界像素,并在两者进行匹配预警时基于天气状况参数灵活调整对应的匹配度阈值,实现了隧道场景的高精度识别,保证了车辆在隧道入口的行车安全。
