Abstract

The present application provides a people counting method and device, the method is applied to a server equipped with a people counting model including an image feature extraction sub-model based on a convolutional neural network and an SSD classification regression sub-model, specifically including: inputting an image frame into an image The feature extraction sub-model generates an image feature map; based on the SSD classification regression sub-model, a default box is generated for each pixel in the image feature map, and the position coordinates and probability scores of each default box are obtained, and the maximum probability score is used as the primary confidence; The top K default boxes with the highest confidence are used as target candidate boxes; based on the position coordinates and probability scores of each target candidate box, bounding box regression analysis and softxmax classification are performed to obtain the coordinate position and final confidence of each target candidate box; based on non- The maximum value suppression algorithm obtains the target frame, and counts the number of people in the monitoring area based on the number of target frames. Using this method can effectively improve the real-time performance of people counting.

Description

technical field [0001] The present application relates to the technical field of image processing, in particular to a method and device for counting people. Background technique [0002] With the development of computer vision, video surveillance technology is becoming more and more important in ensuring public safety and maintaining social stability. People counting is an important part of the video surveillance field. Real-time and effective people counting provides basic data for crowd behavior analysis and plays an important role in preventing crowd congestion and illegal gatherings. [0003] However, most of the existing neural network-based people counting methods use the target detection idea of ​​"area proposal box and classifier". real-time. Contents of the invention [0004] In view of this, the present application provides a method and device for counting people to improve the real-time performance of counting people. [0005] Specifically, this application i...
