Problems solved by technology

Among them, the method based on bottom-level feature fitting has low passenger flow counting accuracy, and the tracking method based on feature points has high computational complexity, which is difficult to meet the real-time counting requirements of the system. The method based on target detection and tracking can ensure the real-time and large-scale counting of the system. Counting accuracy in most cases, but it still needs to overcome the problem of low tracking rate and tracking performance degradation caused by changes in the lighting environment at the entrance of the business hall, which affects the counting accuracy of the system

Embodiment 1

[0088] like figure 1 As shown, Embodiment 1 of the present disclosure provides a method for passenger flow statistics in an electric power business hall based on dynamic target tracking, including:

[0089] A: The camera collects the video stream information at the entrance of the electric power business hall, and decodes the video stream information into several video frames at a frame rate of 25FPS;

[0090] B: Input continuous video frames, perform image denoising preprocessing on each frame of video image, and set a counting line for judging pedestrians entering and leaving in the image at the same time;

[0091] In the image denoising preprocessing, in order to ensure that the edge details of the detection target are not blurred, Gaussian filtering is performed on the video frame image to remove the image noise introduced by the video during acquisition, and at the same time, the image is parallel to the entrance of the business hall and Pointing to the right is the posi...

Embodiment 2

[0141] Embodiment 2 of the present disclosure provides a system for statistics on passenger flow in an electric power business hall based on target dynamic tracking, including:

[0142] The image preprocessing module is configured to: decode the video data stream information obtained by the camera into several continuous video frames at a preset frame rate, use a Gaussian filter to perform image preprocessing on the continuous video frame images, and set a coordinate system and perform image preprocessing. Counting lines for people counting;

[0143] The pedestrian target detection module is configured to: extract the moving foreground image of the video sequence by using the inter-frame difference method on the preprocessed continuous video frame images, and use the integrated learning Adaboost algorithm and the directional gradient histogram feature combination method for the moving foreground image. Perform pedestrian detection to obtain pedestrian targets existing in the v...

Embodiment 3

[0149] Embodiment 3 of the present disclosure provides a medium on which a program is stored, and when the program is executed by a processor, implements the steps in the method for counting passengers in an electric power business hall based on dynamic target tracking described in Embodiment 1 of the present disclosure.

Abstract

The invention provides an electric power business hall passenger flow statistics method and system based on target dynamic tracking. The method includes detecting a pedestrian target in the video frame image after image preprocessing; performing de-duplication processing on the detected targets existing in the tracking target list; tracking targets in the tracking target list by using a KCF algorithm and updating target parameters; obtaining the average moving speed of the pedestrian target in the video by analyzing the target parameters; predicting a video frame number and a specific positionwhen the pedestrian target arrives at the counting line according to the average moving speed; using a target detection model of a KCF algorithm to verify the position of the video frame and the pedestrian target existence condition in the neighborhood range of the video frame, and performing counting statistics on the business hall passenger flow according to the verification result and the initial position of the target; according to the invention, the target tracking process is reduced, the calculated amount of the system is reduced, the target tracking performance of the system is improved, and the high execution rate of the system is ensured.

Description

technical field [0001] The present disclosure relates to the technical field of electric power systems, and in particular, to a method and system for passenger flow statistics in an electric power business hall based on dynamic target tracking. Background technique [0002] The statements in this section merely provide background related to the present disclosure and do not necessarily constitute prior art. [0003] The passenger flow statistics of the electric power business hall refers to the accurate statistics of the number of passengers entering and leaving the entrance through the equipment installed in the operating area, so as to provide a data basis for the scientific management and auxiliary decision-making of the electric power business hall based on the passenger flow information. With the advancement of power reform and the market-oriented competition in the power industry, the power business hall is an important place for power grid companies to provide custome...
