In recent years based on security, quality supervision, inspection and medical for the urgent need of infrared temperature
measurement and infrared display technology, coupled with embedded system to achieve rapid development, which is
widely used in the electronic products and the field of intelligent instruments and industrial control, this paper has
designed a kind of more comprehensive, more efficient and more intuitive infrared thermometer. Unlike previous
handheld infrared thermometer, we regard an embedded Linux system as the system, with its open source code, support
most mainstream hardware platforms, unified peripheral interface and can be customized, to build an embedded infrared
system that has provided strong system support; the pseudocolor techniques and Qt interface display technology make
the image more colorful and the picture function more diverse; With ARM microprocessor as the display and
temperature measuring platform, it costs reduction and reduce volume and power consumption; the FrameBuffer
interface technology and multithreading technology realize the smooth real-time display. And ultimately the display size
of real-time infrared image is 640 * 480 at a speed of 25 frames / sec. What is more, display is equipped with the menu
option so that thermometer can be required to complete the operation through the button. The temperature display system
aims at small volume, easy to use and flexible. I believe this thermometer will have a good application prospect.
