Problems solved by technology

However, the existing traffic management system only establishes a visually realistic traffic environment through 3D modeling and rendering technology, and lacks various dynamic factors in the more important traffic environment, such as cars on the road, traffic signals, roads, etc. Induction information, detector information, etc.
In addition, the establishment of traffic environment through 3D modeling software is a process that requires a lot of manpower and material resources, which cannot meet the requirements of rapid implementation

Embodiment Construction

[0164] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0165] Such as figure 1 Shown, the present invention comprises the steps:

[0166] Step 1, establish a static model; the static model includes a road model, a building model, a plant model and a terrain model;

[0167] Step 2, establishing a dynamic model;

[0168] Step three, state control, decision analysis and vehicle tracking are carried out according to the static model and the dynamic model.

[0169] As shown in Figure 2, the establishment of the road model adopts the following steps:

[0170] (1) Read the electronic map data, detect the image format of the map data, the image format is RGB and RGBA; read the range data of the electronic map;

[0171] (2) (2) According to the pixel grayscale formula: Y=0.299R+0.597G+0.114B, grayscale the electronic map data; divide the electronic map data into two regions according to the grayscale representat...

Abstract

The invention discloses a method for quickly establishing an intelligent traffic three-dimensional field. The method comprises the following steps: step 1, establishing a static model which comprises a road model, a building model, a plant model and a terrain model; step 2, establishing a dynamic model; step 3, performing state control, decision analysis and vehicle tracking according to the static model and the dynamic model. According to the method for quickly establishing the intelligent traffic three-dimension field, a three-dimensional scene is quickly established; besides, dynamic factors are introduced into the road traffic environment, so that the vividness of the virtual traffic environment is improved, and the real state of the road traffic environment is effectively and vividly reproduced.

Description

technical field [0001] The invention relates to the field of intelligent transportation, in particular to a method for quickly establishing a three-dimensional field of intelligent transportation. Background technique [0002] With the continuous advancement of the urbanization process, the appearance of the city has undergone tremendous changes. At the same time, the flow of people, vehicles, and logistics have brought huge pressure on urban road traffic management, such as traffic jams, deterioration of the traffic environment, and frequent traffic accidents. Common problems faced by countries all over the world. The traditional solution to traffic problems is to build or expand roads, but as the population grows, the per capita living space in cities decreases, leaving less and less space for road construction. At the same time, the traffic system is a complex and comprehensive system, and it is difficult to solve traffic problems from the perspective of roads or vehicle...
