Design Of Real-time Mosaic System For Large Field Image

The construction of the large field of view image mosaic system is an important research contents in the field of image drawing,which involves image processing,information processing,embedded system,electronic circuit and so on.it is difficult for one frame to obtain all the scene information that the Practical application required,however,the large field of view and high resolution image which composed by some small field of view images can display a wide range of scene information,and reserve the information of the original scene maximally.The large field of view image mosaic system has a broad application prospects in the civilian and military field.In this paper,the real-time large field image mosaic system has been analyzed and designed.Firstly,the functional requirements of real-time large field image mosaic system has been analyzed,and the design scheme of the system and the structure of the system logic level has been determined.Then,analyzed the function of the computer software in the large field of view image mosaic system,and completed the modular design and interface module of the computer software and the realized some functional modules.Finally,the target Localization based on the coordinates is realized by mathematical modeling and error analysis.The Monte Carlo method is used to analyze the mathematical model accurately,and the error range of the mathematical model is obtained。Through the system integration,testing and performance analysis,the overall analysis,design of the real-time large field image mosaic system and the modular design of the system software on the PC have been completed,and the realization of the software interface module and some functional modules,including the computer The real-time control of the high-resolution digital video,the real-time control of the computer on the stitching computer,real-time display and storage function of the large field of view image obtained by mosaic,and the backtracking function of the large field of view image Based on the UAV attitude information of the ground target location method,and error analysis.the semi-physical simulation of the airborne photoelectric system has been realized in the laboratory simulation environment.
