The invention discloses a vehicle speed prediction-based camera accurate triggering method and an image acquisition system, and the system comprises a speed measurement subsystem which is used for measuring the speed of a train; comprising a high-speed detection sensor group and a low-speed detection sensor group; the high-speed detection sensor group is used for detecting the speed of a train with the speed higher than a speed threshold value, and the low-speed detection sensor group is used for detecting the speed of a train with the speed smaller than or equal to the speed threshold value; the controller is used for predicting the arrival time of the train arriving at a preset acquisition position according to the train speed acquired by the speed measurement subsystem, and calculating the image acquisition triggering time of the image acquisition module according to the arrival time; issuing an instruction for carrying out image acquisition at the image acquisition triggering time to the shooting module; the system further comprises an image acquisition module. According to the invention, accurate speed measurement can be carried out on trains with different speeds so as to predict the time when the trains arrive at the preset shooting place, so that the cameras are accurately triggered to collect train wheel images.
