Abstract

The invention relates to a multiple target tracking-based passenger flow statistics method which comprises the following steps: a deformable part model is used for subjecting a marked human shape sample to off line training operation, and a human shape part model can be obtained; the human shape part model comprises a root filter, a part filter and a space model for positions of parts relative to a root; the human shape part model is used for subjecting each image frame in a video to human shape object detection operation, a two stage track association method is adopted for tracking pedestrian objects in image scenes, movement tracks of pedestrians being detected are obtained, and the pedestrian objects can be counted in real time according to the movement tracks and movement directions in a camera-covered zone. Front end cameras adopted in the multiple target tracking-based passenger flow statistics method are deployed above entries and exits of indoor environments such as supermarkets, supermarkets and the like; vertical or overlooking sampling operation can be performed; tilting sampling scenes can be optimized in a specific manner, the objects can be detected in the camera-covered zone, the number of people going in and out can be counted in real time while the pedestrians are detected and tracked, and correct rates of pedestrian object statistics exceed 90%.

Description

technical field

[0001] The invention relates to the field of counting and counting pedestrian targets in video surveillance, in particular to a method for counting passenger flow based on multi-target tracking. Background technique

[0002] The main purpose of people flow statistics is to make accurate and real-time statistics on the number of pedestrians in the video surveillance system. It is mainly used in various places of activity, such as supermarkets, restaurants, shopping malls, etc. By grasping the information of the number of people in real time, it is possible to rationally dispatch manpower and material resources to improve service quality. Therefore, people counting technology is of great significance in the field of intelligent video surveillance and computer vision, and it is a research topic with practical application value and urgent development.

[0003] The applicability of a people counting system refers to whether the system can operate normally under ...
