Automatic public transport passenger flow counting method and system

Abstract

The invention discloses an automatic public transport passenger flow counting method and system. The method comprises the following steps: I. acquiring a video; II. acquiring a current background edge image; III. acquiring a current video frame edge image and a gradient direction angle of each pixel point; IV. acquiring a target edge image; V. acquiring a candidate circle center linked list; VI. acquiring the contours of the head parts of passengers; and VII. grouping and combining candidate circles to obtain the circular contour corresponding to the head part of each passenger; and VIII. tracing the contours of the head parts of all passengers to obtain the number of the passengers. The method has high counting precision and strong practicability, solves the difficult problem of counting the public transport passenger flow and provides technical support for achieving reasonable distribution, effectively utilizing the limited public transport resource and improving the public transport operating efficiency.

Description

technical field [0001] The invention belongs to the field of image processing, and in particular relates to an automatic counting method and an automatic counting system for bus passenger flow. Background technique [0002] In recent years, with the continuous increase of the number of motor vehicles in our country, as well as the lagging construction of urban driving infrastructure and many problems in urban management, the urban traffic situation in our country is not optimistic. As a public transportation facility with large passenger capacity, high loading rate and low pollution, bus is an effective and direct way to solve urban traffic congestion. However, in my country's public transport system, the statistics of passenger flow are basically done manually, and there are big problems in intelligence, service level and passenger satisfaction, which makes managers unable to know the current passenger flow, while the real-time dispatch of vehicles Completely empty talk.

Problems solved by technology

[0003] Video image automatic passenger flow counting technology has been widely used in urban buses, trains and subways. However, the application of this technology in public transportation systems is not as ideal as that of trains and subways, especially in developing countries with large populations such as China and India. The large population density makes the order of passengers getting on and off the bus more chaotic, which greatly increases the difficulty of realizing the automatic passenger counting algorithm. research focus

[0004] The bus passenger flow counting technologies that have been used abroad include pedal systems, automatic ticketing and collection devices, and thermal infrared counting devices. Although these technologies have been used to a large extent, these devices generally have high costs and the counting accuracy under certain circumstances will be affected
