A vehicle pre-warning system comprises a camera device, a processing device and a warning device. The camera device is used for shooting a scene to acquire image frames corresponding to the scene; the processing device judges whether moving articles exist in the scene or not according to the image frames; if yes, the processing device calculates speeds of the moving articles according to positions of the articles and the scene shooting frequency of the camera device; the processing device further sets corresponding pre-warning levels according to the positions and the speeds of the moving articles; the warning device outputs corresponding warning messages according to the pre-warning levels. The invention further provides a vehicle pre-warning method.
