Visual data input method based on intersection information holographic perception

Abstract

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.

Description

technical field [0001] The invention relates to the technical field of intelligent traffic control, in particular to a visual data input method based on holographic perception of intersection information. Background technique [0002] The intersection traffic signal control system is the key to improve the efficiency of intersection traffic, the current intersection signal control mode can be divided into timing control and adaptive control. The timing control mode does not require detection equipment. The traffic engineer only needs to configure the corresponding cycle, green signal ratio, and phase difference parameter scheme according to different time periods. The signal machine will automatically execute it at the specified time regardless of any changes in the traffic flow at the current moment. Pre-configured by traffic engineers, the biggest feature of this mode is low cost, but the crossing efficiency is low. When a motor vehicle encounters a red light, no motor veh...
