Embodiment Construction

[0044] The invention provides a real-time traffic road network perception system. The real-time traffic road network perception system converts a large amount of image data provided by vehicles into data points that can be used by the system through image analysis, and then generates real-time traffic information through statistical methods and artificial intelligence learning methods. The traffic road condition information generated by the system can be fed back to the car navigator for the car navigator to judge the travel time of the road section, judge the road condition (such as one-way street), or other real-time information (such as road maintenance). In addition, the positioning information provided by the global positioning system (global positioning system) may cause poor reception due to obstacles in the metropolitan area (such as tunnels, viaducts), and the traffic road condition information generated by this system can also provide positioning correction informatio...

Abstract

The disclosure provides a real-time traffic situation awareness system. In one embodiment, the real-time traffic situation awareness system receives driving data from a car, wherein the driving data comprises an image, GPS data, and gyroscope sensor data. The real-time traffic situation awareness system comprises an image processing unit, a feature extraction unit, a feature matrix database, a data grouping unit, and a situation awareness unit. The image processing unit processes the image to generate a processed image. The feature extraction unit generates a data point according to the processed image, the GPS data, and the gyroscope sensor data. The data grouping unit searches the feature matrix database for a plurality of feature groups of an optimal feature matrix corresponding to a geographic area according to the GPS data of the data point. The situation awareness unit analyzes the feature groups to generate traffic information.

Description

technical field [0001] The invention relates to a computer system, in particular to a computer system for traffic road condition perception. Background technique [0002] The latest trend in vehicle navigation is to provide real-time road condition information, such as vehicle speed, construction, accidents, and road changes, for drivers' reference. Generally speaking, manufacturers of vehicle navigators mostly integrate public information provided by public entities, and the sources of information include: 1. Vehicle detectors are installed under the road surface to calculate the number of vehicles passing the road to obtain real-time traffic information. However, it is necessary to excavate the road surface to install the vehicle detectors under the road surface, which consumes too high cost, resulting in uneconomical deployment of the vehicle detectors. 2. Monitor and judge through road cameras, and cameras are currently limited to important roads and intersections, and ...
