摘要
为了进行身份识别和无接触式测温,设计基于32位系列微控制器芯片(STMicroelectronics 32 bit,STM32)的测温与身份识别系统。采用开源机器视觉(open machine vision,OpenMV)进行身份识别,使用红外温度传感器进行无接触温度测量。OpenMV准确识别人脸并将数据传给单片机,使其控制发光二极管(light emitting diode,LED)灯和蜂鸣器进行相应输出。红外温度传感器测量温度,数据通过单片机准确地输出在有机发光二极管(organic light emitting diode,OLED)屏幕上。实验数据表明,温度控制精度在±0.7℃,总体识别成功率高于80%。系统识别准确,温度测量以及身份识别效果明显。
In order to carry out identification and contactless temperature measurement, a temperature measurement and identification system based on STMicroelectronics 32 bit(STM32) is designed. Open machine vision(OpenMV) is used for identification and infrared temperature sensor is used for non-contact temperature measurement. OpenMV can recognize the face accurately and transmit the data to the microcontroller unit(MCU) to control the light emitting diode(LED) lamp and buzzer for corresponding output. The infrared temperature sensor measures the tempera-ture, and the data is accurately output on the organic light emitting diode(OLED) screen through the MCU. The experimental data show that the temperature control accuracy is ±0.7 ℃, the overall recognition success rate is higher than 80%, the system identification effect is obvious.
