EMCCD图像处理系统及应用技术研究
|
摘要
EMCCD能够在微光条件下,获得高质量的图像。我们开发出基于EMCCD的图像采集和处理软件,并把它应用到X射线数字成像系统,能够提高成像的速度并获得高清晰图像。该项技术目前在国内还处于发展的初级阶段。
在论文中,深入地研究了EMCCD的工作原理和结构,以及对型号为TC285SPD的EMCCD做了详细的分析研究;分析了EMCCD图像采集卡的一些相关特性,在此基础上编制一套与EMCCD相匹配的图像采集与处理软件,研究了图像缩放、边缘检测、去噪等图像算法,并编写了相关程序;详细地介绍了基于EMCCD的X射线数字成像系统的系统构成以及工作原理;另外,为了满足射线检测的要求,在Andor公司数字相机基础上设计开发了图像远距离传输技术,详细设计了具体方案与接口电路,满足了实时性图像和远距离传输的要求。在课题组的帮助下,初步完成了一套基于单晶转换屏与EMCCD探测器的射线成像系统。图像处理软件与射线成像系统还有待于进一步研究。
EMCCD can get high quality image on the condition of low light. It can enhance imaging speed and obtain high clear image .we finish the software of collecting image and image processing basing on EMCCD,and EMCCD can been used in X-Ray digital imaging system. This technology has been in the primary stage recently in our country.
In this text,we research the work principle and configuration of EMCCD and the model TC285SPD of EMCCD have been research deeply. We also research the related characteristics about the imaging block based on EMCCD and finish the software of collecting image and image processing suited with EMCCD.In image processing aspect, we work over some processing image methods, such as zoom, edge inspect and getting rid of noise. Meanwhile, we compile related program.And introduced the X-Ray digital imaging system based on EMCCD in detail, including system composing and the work principle. For sake of the requiring of radio inspecting, we design and develop image long distance transmission technology on the basis of Andor company digital cameral. We design particular project and interface circuit in order to getting the requiring of real time imaging and long distance transmission. On the help of task group, we have finished a suit of radio imaging system based on single scintilla and EMCCD detector. Image processing and radio imaging system will been more researched.
