Problems solved by technology

However, users' usage environments vary greatly, and it is difficult to collect heat maps of users in various scenarios
In addition, access control is an embedded device with limited computing power. If the face detection model is used to detect faces on the heat map in the existing functions, the CPU load will be overloaded, causing the screen to freeze

Abstract

The invention relates to a method and system for determining face coordinates on thermal imaging, equipment and a storage medium, and belongs to the technical field of face recognition. The method comprises the following steps: acquiring an imaging picture shot by an access control camera and a thermodynamic diagram shot by a thermal imaging camera; obtaining a first face coordinate of a field angle overlapping area of the thermal imaging camera and the access control camera, wherein the first face coordinate is obtained by recognition of an imaging picture by the access control equipment; and substituting the first face coordinate into a preset formula to calculate a second face coordinate on the thermodynamic diagram. According to the embodiment of the invention, the face coordinates on the thermodynamic diagram can be quickly positioned through small computing power, the CPU load is very small in the computing process, the recognition picture of the access control equipment is smooth, and good user experience can be guaranteed.

Description

technical field [0001] This application relates to the technical field of face recognition, in particular to a method, system, electronic device and storage medium for determining the coordinates of a face on a thermal image in an access control scene. Background technique [0002] Using infrared thermal imaging method to measure body temperature has the advantages of fast, convenient and unattended. Every pixel on a thermal image contains temperature information. The process of temperature measurement is to retrieve the temperature of the person on the heat map, but since the entire heat map contains the entire environment, there may be interference factors such as high-temperature objects, other people around, etc., so if the entire heat map is used for retrieval, affected by these disturbances. In order to accurately measure the temperature of a person, it is necessary to identify the position and size of the person in the heat map. [0003] In related technologies, th...
