Binocular infrared photography-based bus passenger flow counting device and method

Abstract

The invention discloses a binocular infrared photography-based bus passenger flow counting device and method. The binocular infrared photography-based bus passenger flow counting device comprises a calculation apparatus, an infrared camera A, an infrared camera B and a counting display apparatus, wherein the infrared camera A and the infrared camera B are located in two different positions above a photographed point respectively; and the calculation apparatus collects videos from the infrared camera A and the infrared camera B in real time. The method comprises the steps of running a binocular vision algorithm by the calculation apparatus; calculating depth information of points on images from the two different cameras; drawing a contour line; extracting a human head quantity contained in the image in combination with human head shapes and priori knowledge of a distribution law of the contour line, wherein the extracted human head quantity is within a predetermined time; and tracking the human head quantity by the infrared camera A or the infrared camera B. According to the counting device, the statistical precision is improved and the situations that human head identification rate is low and children are shielded due to insufficient light are avoided.

Description

technical field [0001] The invention relates to the technical field, in particular to a bus passenger flow counting device based on binocular infrared imaging and a method thereof. Background technique [0002] Passenger flow is usually also referred to as the number of people, and it is an indispensable data for management and decision-making in public places such as buses, airports, large shopping malls, shopping centers, and exhibition halls. Passenger flow statistics are an important part of the Intelligent Transportation System (ITS). The accuracy of passenger flow statistics directly affects the operation and efficiency of intelligent bus dispatching. The main purpose of the bus passenger flow statistics system is to realize real-time automatic statistics of the number of people getting on and off the bus, and to send the data to the back-end system management platform in real time for storage, forming data reports and data analysis. As a result, the monitoring center...

Problems solved by technology

However, due to uneven intensity and insufficient light at night, this method often leads to a low head recognition rate.

In addition, when the number of passengers on and off is dense, occlusion will occur; especially children are more likely to be occluded and cannot be recognized
