The traditional way of limitations, has been unable to meet the applicationrequirements, therefore, need to be more efficient, more accurate, low cost, convenientoperation, easy analysis and conservation methods, realize the beam parametersmeasurement and analysis. With the CCD technology and the continuous developmentof computer technology, has been based on the CCD detector is a foundation, use ofimaging modalities in indirect measurement spot characteristic system.Based on the spot detection and analysis applications in the background, designCCD imaging equipment as the basis, the use of digital image processing algorithm ofintensity distribution of imaging spot data, spot centroid position and other relatedparameters estimation and measurement.In this paper, in accordance with the norms of software engineering, using theUML unified modeling language integrated design system. From the business needs toextract the functional modules of the system, including CCD correction, acquisition andcontrol, image denoising, enhancement display, parameter calculation, in the light ofeach module are designed in detail, including the specific algorithm and activitydiagram, finally in Visual C++2005platform for the realization of each functionmodule and unit and system testing.The main work of this thesis includes:1, Based on the analysis of the non-uniformity of the CCD sensor in the imagingprocess, the CCD calibration algorithm are designed and implemented to improve theimage quality.2, Using SDK Software Development Kit, the spot image acquisition functions aredesigned and implemented, which are able to complete the continuous, pulsed lightsource complete capture and provide real-time display function.3, Because of spot in the acquisition, transmission in the process of noisecharacteristics, the system contains corresponding denoising algorithm, the spot imagepreprocessing, that data for subsequent analysis to provide more realistic spot for spot.4, Different two-dimensional pseudo-color enhancement algorithms are implemented, those provides to the user a high resolution observation mode. In addition,using3D modeling, comprehensive and three-dimensional display spot each dimensiondistribution.5, based on the processed image data, calculating the characteristic parameters ofspot, is convenient for the user to quantitative analysis of spot characteristics.The system can realize the continuous light or pulse light source collection, andbased on CCD correction and denoising pretreatment, access to truly reflect the spotcharacteristics of image data, carried on the corresponding analysis, and to the twodimensional or three dimensional pseudo color transformation way, is convenient forthe user from the aspects of observation spot characteristics.This system is in good working condition, the test module can meet the designrequirements, to meet the needs of users, the system can be safe, reliable, stableoperation.
