The invention provides a visual data input method based on intersection information holographic perception, and the method comprises the steps: firstly obtaining the information of a plurality of images collected by a plurality of pieces of video equipment in an intersection, and enabling the information to comprise intersection images and the images of a plurality of types of target objects, suchas motor vehicle, non-motor vehicle and pedestrian information; in order to effectively extract information related to traffic control in an intersection and avoid repeated images and redundant images (such as green belts and buildings), target objects are subjected to duplicate removal and combination, the target objects are subjected to duplicate removal through virtual grids in multiple images, information of useful objects at the intersection is recovered, and the information of the useful objects at the intersection is recovered. Then the intersection and the target object are convertedinto an electronic graph form, and redundant information irrelevant to traffic control in the electronic graph form is removed so that the traffic information of the intersection can be displayed in areal-time electronic graph form, and the intersection information is effectively restored; the problem that repeated images and redundant image information exist in image information collected by a plurality of cameras is solved.
本发明提供基于路口信息全息感知的可视化数据输入方法,首先获取路口内由多个视频设备采集的多幅图像信息,在这些信息中包括了路口图像以及机动车、非机动车和行人信息等多种目标对象的图像,为了有效提取路口中的交通控制有关的信息,避免重复的图像和冗余的图像(如绿化带、建筑物等),先将目标对象进行去重合并,在多幅图像中通过虚拟网格将目标对象去重,恢复出路口的有用的对象的信息,然后将路口和目标对象转化为电子图的形式,去除其中的与交通控制不相关的冗余信息,这样就可以通过实时的电子图的方式来显示路口的交通信息,使得路口信息有效还原,解决了多个摄像头采集的图像信息中存在重复图像以及冗余图像信息的问题。
