摘　　要：为了对物体表面温度实时在线测量并能实时获得红外热图像,论文设计了一种低成本的红外热成像系统。该系统以微处理器为控制核心,通过IIC接口接收MLX90640所采集到的温度数据,并实时显示测量区域的红外热图像,针对红外传感器分辨率低的问题,提出了一种基于边缘保护的新插值算法,可有效提高红外热图像的分辨率。实验结果表明,该系统可以实时获得高分辨率、高质量的热力图,准确定位发热点位置,具有良好的工程应用前景。In order to measure the surface temperature online and obtain infrared thermal image in real time,a low-cost infrared thermal imaging system is designed.The system uses a microprocessor as the control core,receives the temperature data collected by MLX90640 through the IIC interface,and displays the infrared thermal image of the measurement area in real time.Aiming at the low resolution of the infrared sensor,a new interpolation algorithm based on edge protection is proposed,which can effectively improve the resolution of the infrared thermal image.The experimental results show that the system can obtain high resolution and high quality thermal map in real time and locate hot spots accurately,which has a good engineering application prospect.
