Method and system for achieving intelligent bus stop board

Abstract

The invention relates to a method and a system for achieving an intelligent bus stop board. The method comprises the steps of locating images obtained by a camera and obtaining a locating picture of a bus license board, carrying bus license board cutting to the locating picture to obtain a character binary picture, obtaining a character grey-scale picture from the locating picture of the bus license board according to the boundary location of the character binary picture, filtering the character grey-scale picture through a Gabor filter set to obtain Gabor characteristics, obtaining a digital group by the Gabor characteristics through a corresponding batch processing (BP) neural network, when the largest numerical value of the digit group is larger than a threshold value, obtaining a character, corresponding to the largest numerical value, in a recognition network as a recognition result, when the largest numerical value of the digit group is smaller than or equal to the threshold value, recognizing and processing the character binary picture corresponding to the Gabor characteristics, obtaining average moving speed of a corresponding bus according to the character recognition result of the bus license board and multiple frames of images obtained by the camera, and obtaining the shortest waiting time of all bus stations according to the average moving speed and displaying the shortest waiting time to passengers waiting for the bus through the bus stop board.

Description

technical field [0001] The invention relates to the technical field of public transportation, in particular to a method and system for realizing an intelligent bus stop board. Background technique [0002] With the acceleration of the urbanization process, the traffic congestion in the city is becoming more and more serious, and people's travel is becoming more and more inconvenient. Taking the bus is one of the important ways for people to travel, but because of the inaccurate arrival time, in many cases, it takes a long time to wait for a bus, which makes most people have to change other modes of travel. [0003] At present, the data transmission channels used by existing smart bus stop signs on the market are generally wired optical cables and wireless telecommunication networks. However, wired optical cables have problems such as expensive construction, high operating costs, and difficult maintenance. Based on this background, the application number is 201010042852.9 w...

AI Technical Summary

Problems solved by technology

However, this technical solution has a big disadvantage that it is impossible to know the estimated time from the bus traveling on the road to each platform of the traveling route.

Even if the reliability of the time obtained by combining this technical solution with the existing technology is not high, it cannot make the user's travel and life more convenient
