Vehicle dynamic path navigation method and device for obtaining road condition video information in real time

Abstract

The invention discloses a vehicle dynamic path navigation method for obtaining road condition video information in real time. The method comprises a navigation device firstly calculating at least one navigation path from the starting point to the destination according to the topological relation of the road nodes in navigation data; then, matching traffic camera information to the navigation path, calculating the path distance from each traffic camera point to vehicle current point, and meanwhile, carrying out ranking based on the path distance from each traffic camera point to the vehicle current point; and at last, obtaining and displaying real-time dynamic traffic video pictures. The invention also discloses a vehicle dynamic path navigation device for obtaining the road condition video information in real time. The device comprises a path programming module, a traffic camera data matching module, a dynamic traffic video displaying module and a comprehensive control module. Therefore, the traffic circulation efficiency of a road network can be effectively improved, and the problem of traffic jam is greatly improved.

Description

technical field [0001] The invention relates to a navigation system, in particular to a vehicle navigation system. Background technique [0002] With the sustained and rapid growth of the national economy, cars have gradually become popular, the number of civilian cars has continued to increase, passenger cars and trucks have grown in an all-round way, private cars have quickly entered ordinary families, and traffic congestion has become more and more more serious. [0003] In the prior art, the traffic navigation system cannot provide real-time traffic dynamic information, and the positioning electronic map data provided by the system is static and does not really reflect the current road traffic conditions. The user can only rely on dialing a mobile phone and listening to the traffic radio station to inquire about the real-time traffic conditions of each interval on the driving route or each crossing during driving. When you are on a high-speed vehicle, making a phone ...

AI Technical Summary

Problems solved by technology

This system solves the above problems to a certain extent, but the system also has the following defects: first, the system is complex in technology, requires a lot of equipment, and the project cost is expensive, so it cannot be widely promoted in the market; second, the system can only be passively The collected data is calculated according to the established algorithm, and the obtained data are all data under the same weather conditions. Once the weather conditions change, such as heavy rain, heavy snow, etc., even under the same traffic flow, the traffic conditions will change greatly. , and the system cannot handle the
