The invention discloses an infrared and visible light image fused automobile anti-blooming video image processing method, solving the traffic safety problem caused by automobile blooming at night from the view of collision object avoidance. The method includes acquiring an infrared image and a visible light image of a night road; performing image registering by taking the infrared image as a reference, enhancing the infrared image and the visible light image; extracting the brightness signal component Y and two chrominance signal components U and V of the enhanced visible light image; fusing Y and the enhanced infrared image wavelet to obtain a new brightness signal component Y'; and subjecting Y' and U and V to YUV inverse transformation to obtain a final color fusion image. The image enhancement processing is added after registration, and the parameters are optimized, the brightness and dark detail information of the fused image are greatly retained and improved while the blooming is eliminated. The method can effectively prevent the collision caused by blooming and is applicable to the automobile anti-blooming filed.
