The invention relates to the technical field of real-time video image processing, in particular to an expressway-oriented full-road-domain video image visual display method, and aims to solve the technical problems that information fusion work among multiple subjects needs to spend a lot of time for manual registration, and the display effect of video fusion is not real and ideal enough. The method comprises the following steps: acquiring video information of each camera device; the acquired video information is preprocessed; acquiring internal parameters, external parameters and distortion parameters of a camera of the camera equipment, establishing a distortion model based on the distortion parameters, and converting the deformed video into a normal video to obtain third video information; performing registration to obtain fourth video information; performing image fusion on the fourth video information by adopting an optimal suture line method to form an integral video for projection; in the projection of
