The invention relates to the technical field of traffic safety, in particular to a road safety early warning method based on multi-sensor fusion and a computer vision technology. The method comprises the following steps: respectively generating a position initial Boolean value and a speed initial Boolean value based on data of a current target object, and obtaining a weighted Boolean value by the position initial Boolean value and the speed initial Boolean value through a weighting algorithm; object and lane line detection is carried out on the current target object image, obstacles and lane lines are identified, and the driving direction and speed of the current target object at the next moment are predicted; obtaining a final fusion speed of the current target object based on the measurement speed, the simulation speed and the prediction speed at the next moment; and generating a standard driving Boolean value according to the type of the target object, the final fusion speed, the predicted driving direction and the positioning and position information, evaluating the collision danger level through the standard driving Boolean value and the weighted Boolean value, and generating a corresponding early warning signal. The road safety early warning comprehensiveness and accuracy are improved.
