Embodiment Construction

[0045] In order to make the purposes, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments It is a part of the embodiments of the present application, but not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the protection scope of the present application.

[0046] Currently, one of the methods for predicting the number of people in dense crowds is based on the detection method, which mainly detects the head and shoulders of the human body, and obtains the number of people through the number of detection frames. The other is to directly predict the number of people by regression, whic...

Abstract

The present application provides a method, device, device and storage medium for predicting the number of people in a dense crowd, including: converting a first image of the number of people to be determined into a corresponding first heat map according to a heat map conversion model, and according to the first heat map Determine the number of people in the first image, wherein the heat map conversion model is a model trained according to the pre-calibrated second image and the heat map corresponding to each second image, which realizes the prediction of the number of dense crowds, and improves the The accuracy of the prediction of the number of dense populations improves the management efficiency.

Description

technical field [0001] The embodiments of the present application relate to the technical field of artificial intelligence, and in particular, to a method, apparatus, device, and storage medium for predicting the number of people in a dense crowd. Background technique [0002] With the rapid economic development and population growth, the flow of people in public areas such as offline retail, airports, and subways is increasing. Early warning and people flow prediction have become one of the basic means necessary for managers in various regions. [0003] There are currently two methods for predicting the number of people. One is based on the detection method, which mainly detects the head and shoulders of the human body. Specifically, the number of people is obtained through the number of detection frames. The other is to directly predict the number of people by regression. Specifically, the number of people or the density level is directly obtained through the Convolutiona...
