Problems solved by technology

[0003] In the prior art, the detection of the congestion level of a certain road section generally relies on a single-factor detection model, such as satellite remote sensing images, on-site vehicle speed or on-site camera images, but single-factor detection is easily interfered by its own detection system, such as Satellite remote sensing is easily interfered by the thickness of atmospheric clouds, resulting in low detection accuracy

Embodiment Construction

[0014] The following will describe in detail the implementation of the system for detecting road section congestion level based on remote sensing communication according to the present invention with reference to the accompanying drawings.

[0015] With the development of the automobile industry, people rely on automobiles to travel more and more frequently. On unfamiliar roads, people often need to rely on navigation to avoid congested roads and improve traffic efficiency. Therefore, the congestion situation of each road section is particularly important in car navigation.

[0016] The current navigation equipment generally relies on a single-factor model for the detection of road congestion. This model is easily disturbed, resulting in the improved reference data having no reference value or even misleading, which brings inconvenience to people's travel.

[0017] In order to overcome the above-mentioned shortcomings, the present invention builds a road section congestion deg...

Abstract

The invention relates to a road segment congestion degree detection system based on remote sensing communication. The detection system comprises a satellite remote sensing image receiving device, a vehicle terminal data receiving device and a computer control device. The satellite remote sensing image receiving device receives road segment remote sensing images of a target road segment sent by a remote sensing satellite. The vehicle terminal data receiving device receives a vehicle real-time speed of a vehicle terminal on the target road segment. The computer control device is used for determining the congestion degree of the target road segment according to the road segment remote sensing images and the real-time speed of the vehicle. According to the invention, the road segment remote sensing images and the vehicle real-time speed are combined for determining the congestion degree, and the weight of each factor for the congestion degree determining is set according to the magnitude of cloud layer thickness.

Description

[0001] The present invention is a divisional application of a patent with the application number 201510307548.5, the application date is June 6, 2015, and the invention name is "Road Section Congestion Level Detection System Based on Remote Sensing Communication". technical field [0002] The invention relates to the field of remote sensing communication, in particular to a detection system for road section congestion level based on remote sensing communication. Background technique [0003] In the prior art, the detection of the congestion level of a certain road section generally relies on a single-factor detection model, such as satellite remote sensing images, on-site vehicle speed or on-site camera images, but single-factor detection is easily interfered by its own detection system, such as Satellite remote sensing is easily interfered by the thickness of atmospheric clouds, resulting in low detection accuracy. [0004] For this reason, the present invention proposes a ...
