Design of Infrared Face Recognition Temperature Measurement System Based on Harris Algorithm
This paper points out that human body temperature is an important indicator to reflect the health of human body.Therefore,in this paper,a set of access control system based on infrared detection and face recognition technology is designed.In this system,STM32F103C8T6 microcontroller is used as the main control module,and OpenMv4 H7 is used as the camera acquisition module to collect face pictures,and Harris feature extraction algorithm is used to extract feature points to realize the function of face learning and recognition;MLX90614 infrared temperature sensor is used to measure the temperature of the human body or object,and the temperature is compared with the threshold,and the voice and light alarm can be realized when the threshold is exceeded.Through the test,the system to the human body and object temperature measurement error control is within 0.5℃,the accuracy of face recognition is 98%,the system is simple to operate,reliable to run,and the function is better realized.
