The invention discloses a mountain road curve vehicle crossing early warning method based on videos, and belongs to the technical field of video images. The method includes the following steps of firstly, conducting infrared camera shooting through an infrared camera to obtain video image signals; secondly, conducting vehicle target detection through a self-adaptive Gaussian mixture modeling method to obtain vehicle characteristics; thirdly, calculating the average vehicle area of multiple frames, and judging the running directions of vehicles; fourthly, conducting vehicle tracking on vehicle targets entering the camera shooting range through the MeanShift algorithm; fifthly, measuring vehicle speeds through the angular point characteristic matching algorithm, comparing the vehicle speed with the maximum regulated vehicle speed at a curve, and conducting front road condition information display and real-time voice prompting or early warning on the two ends of the curve. By means of the infrared camera, the vehicle target detection can be completed under the conditions that the weather is bad and visibility is low, the curve vehicle crossing early warning is conducted through information display and real-time voice broadcasting, and the aim of comprehensive effective early warning in the running process is achieved.
