The invention discloses a vehicle collision early warning method based on multi-sensor fusion, and the method comprises the steps: carrying out the preprocessing of original data collected based on a millimeter wave radar, and obtaining a target data set; acquiring image data based on a camera, and performing enhancement processing in an image preprocessing stage based on an image enhancement algorithm to obtain an image data set; performing data fusion processing according to the obtained target data set and the image data set; when a front obstacle target is detected in real time, a decision is made according to a collision early warning control strategy, and a driver is assisted in recognizing front dangers in real time in a proper mode. According to the invention, obstacle identification and distance sensing are carried out through the camera and the millimeter wave radar, collision early warning based on multi-sensor fusion is more sensitive and efficient, early warning can be carried out before collision, and the development period is shortened while the development cost and false alarm are effectively reduced.
