Abstract
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.
