Real-time subway carriage prompting system based on visual analysis and identification method

Abstract

The invention relates to a real-time subway carriage prompting system based on visual analysis. The system comprises an image acquisition unit, a sensor unit, an image storage and transformation unit, an image processing unit, a transfer unit and a prompting unit, wherein the sensor unit is used for sending out shooting signals; the image processing unit is used for receiving digital image signals from the image storage and transformation unit, judging the number of the passengers who transfer into a carriage from another carriage according to images taken by a first CCD camera, judging the number of the passengers who get on the carriage according to images taken by second CCD cameras, and transmitting the real-time number of the passengers in the carriage to the transfer unit; the transfer unit is used for transmitting data from the image processing unit to the prompting unit; and the prompting unit is used for displaying the data from the transfer unit through a display screen in a passenger waiting area in next subway station. Through the system, the numbers of passengers in carriages can be judged in real time, so that passengers can obtain the information of relatively uncrowded carriages, and unnecessary crowding and passenger pick-up time are reduced.

Description

technical field [0001] The invention relates to the technical field of real-time prompting of subway cars, in particular to a real-time prompting system and recognition method for subway cars based on visual analysis. Background technique [0002] In recent years, my country's urban rail transit has developed rapidly, and major cities are carrying out a large number of urban subway construction projects. In the case of increasing traffic congestion, subway travel has gradually become a travel choice for more and more people. The comfort and intelligence of the subway have also become the needs of the society. When taking the subway, it often happens that some cars have fewer people and some cars have more people, but the passengers at the next stop do not know the situation when they line up to get on the train, which will cause a waste of space and congestion on the train, causing boarding. Extended driving time, reduced safety factor, etc. At present, there is no method...

AI Technical Summary

Problems solved by technology

At present, there are many methods of counting the number of people in buses, counting the number of people in subways, and preventing fare evasion. Traditional methods include photoelectric switches, pressure sensors, etc. These methods are not accurate in detecting the number of people, and the response is relatively slow. The processing technology is also aimed at counting the number of people, but the subway has a huge flow of people, the situation is complicated, and the method of counting the number of people is also more complicated
