Method for analyzing number of people and system thereof

Abstract

A method for analyzing a number of people includes an image shooting step and a front-end analyzing step. In the image shooting step, a first image and a second image are obtained. In the front-end analyzing step, a foreground object analysis is operated, and a plurality of foreground objects located at a region of interest in the first image are obtained. A human body detection is operated, and at least one human body and a location thereof of the second image are obtained. An intersection analysis is operated, and the location of the human body is matched to the first image. A number of people estimation is operated to estimate the number of the people according to the first covering ratio, a number of the human body, and a second covering ratio of all the foreground objects to the region of interest.

Description

BACKGROUNDTechnical Field[0001]The present disclosure relates to an analyzing method and a system thereof. More particularly, the present disclosure relates to a method for analyzing a number of people and the system thereof at a single site.Description of Related Art[0002]Pedestrian counting is a key factor in transportation systems. Through counting the number of the people standing outside the gateway of an automated shuttle or standing at the waiting station, analyzing efficiency of a service strategy can be improved. For example, the analysis of the number of the people is helpful for the practitioners to conduct dynamic bus dispatching.[0003]In order to count the people, a method that checking the number of the people by checking the number of the connections of a wifi system is developed. By defining the flow rate of a wireless signal from a cell phone or a portable device of a pedestrian in a specific range, the number of the people can be obtained. However, the wireless sig...

Benefits of technology

This patent describes a method and system for analyzing the number of people in an image. The method involves capturing images of a shot zone from both a top-down and side angle, and using foreground object analysis to identify human bodies and their location in the image. The system includes cameras placed at the shot zone and a controlling unit to process the images and calculate the number of people in the shot zone based on the size and location of foreground objects. The technical effects of this invention include improved accuracy in analyzing the number of people in an image and useful information for various applications such as security and sports arenavisioning.

Problems solved by technology

However, the wireless signal is non-directional, and the transmitting terminals all around will be received; as a result, the counting result cannot be focused in a specific area.

However, the error of a commercial type GPS is up to 10 m; therefore, an accurate flow rate of the people has to be constructed by the movement and the historical data, and there has disadvantages of complex calculation and large dataset.

Moreover, the connected articles which pass through the system together cannot be identified; as a result, the counting result is not accurate.

However, the objects may be seriously covered or interfered.
