The Design, Based On The Dm642 Infrared Thermometry

In recent years, the development of DSP technology has put the theory achievement of digital signal processing field into practical systems, and pushed the progress of new theory and application. At the same time, it plays an important role in the field of image processing. With the development of infrared imaging technology and infrared focal plane array (IRFPA) solid image detectors, IRFPA is widely used in various imaging system in the military, industrial and commercial fields. This paper designed and implemented a module for the real-time processing of the image based on the TMS320DM642, with the linking of the infrared thermal imaging technology and the digital signal processing (DSP) technology, based on the project called "the development of the instrument for the measuring of the temperature using the un-cooled infrared focal plane". This paper researched the technology of the processing of the infrared image deeply, on the base of the character of the infrared image and the requirement of the application. Many experiments have been done to the temperature calibration of the un-cooled infrared focal plane detector, using the high accuracy blackbody, according to the experimental data. At the aspect of image enhancement technique, this paper proposed the adaptive gray-scale extension and enhanced the higher temperature region, which is important to this system. Through analyzing the design methods of many multimedia real-time processing platforms and the design theory and principle of the high-speed electronic system, the design of main frame of video processing module has been completed.
