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 the whole video, video frame textures are displayed at places where the video can be displayed, and original textures of the three-dimensional model are displayed at places where the video frame textures cannot be displayed.

    本发明涉及实时视频图像处理技术领域,具体涉及一种面向高速公路的全路域视频图像可视化展示方法,为解决多个主体之间的信息融合工作需要花费大量时间进行人工配准,视频融合的显示效果不够真实、理想的技术问题。本申请方法包括:获取各个摄像设备的视频信息;对获取的视频信息进行预处理;获取摄像设备的摄像头内部参数、外部参数和畸变参数,基于畸变参数建立畸变模型,将变形的视频转换为正常的视频,得到第三视频信息;配准得到第四视频信息;采用最佳缝合线方法对第四视频信息进行图像融合,形成一个整体视频进行投影;整体视频进行投影中能够显示视频的地方显示视频帧纹理,不能显示视频帧纹理的地方显示三维模型的原有纹理。
