Design And Implementation Of Electronic Image Stabilization Module In An Optical Device

In recent years,optical measurement has been widely used in the field of spaceflight.With the development of science and technology,optical equipment has been constantly updated,which makes it play an important role in the field of aerospace applications.The optical equipment is mainly responsible for the measurement of the target scene in the spaceflight experiment.The main task is to calculate the flight trajectory of the target and to output the real-time target real-time.In the process of use,due to the defects of the optical equipment itself(such as large volume,insufficient hardware level and so on),which are easily affected by the environmental factors,the ability of the optical equipment to track the target stably and continuously cannot meet the requirements of the test task.Especially,the quality of the outgoing image is not high,so the optical equipment can not fully play its unique characteristics in some mission-critical activities.In recent years,with the rapid development of electronic image stabilization technology,its characteristics of high speed,high accuracy and low power loss are especially obvious,and it has been gradually applied in various fields,mainly in real-time monitoring,real-time display of exterior scene in vehicle and ship.Weapon equipment aiming system is widely used.Some domestic scientific research institutions have also begun to apply image stabilization technology to optical equipment.On the basis of full research on image stabilization technology both at home and abroad,and in combination with the needs of experimental activities,the research work of electronic image stabilization module in optical equipment is carried out in this paper.In the tracking process,the optical equipment can output stable and clear images in real time,play the essential advantages of the optical equipment,and more adapt to the requirements of target scene measurement in space missions.In the research and development system,the thesis mainly carried out the following work:(1)To investigate the use of electronic image stabilization in China,especially in weapon equipment and optical measurement equipment,in order to reduce the detours in the follow-up research process;(2)Study the principle of electronic image stabilization algorithm,compare the advantages and disadvantages of various algorithms,find the image stabilization technology suitable for modern large aperture optical equipment,analyze the key points and difficulties encountered in the process of implementation;(3)According to the actual application,on the basis of fully combining the characteristics and functions of the equipment,this paper puts forward the requirement analysis,and compiles the function module on this basis,so that it can be better embedded in the equipment software.In the process of operation,it does not conflict with the software of the equipment itself,and combines with the task to observe the change of image quality before and after image stabilization to achieve the image stabilization effect;(4)Function debugging combined with tasks,real-time monitoring of image stabilization effect and software operation,analysis of its reliability and security,find out the deficiencies,find out the parts that need to be improved At the end of this paper,the paper summarizes the work of the paper,puts forward the shortcomings of the system,and puts forward some suggestions for the follow-up work;(5)At the end of this paper,the full text work is summarized,aiming at the deficiency of the system put forward in the pre-test,some suggestions are put forward for the follow-up work.
