In recent years,integral image can display a true three-dimensional(3D)color image with full parallax and continuous viewing.without incoherent and ambient light.Its system is simple and convenient.Capture the image is two-dimensional(2D)images which can be optimized by using the existing 2D image processing technology.Integral image have been extensively researched for many applications in the fields of military aerospace,aerial photography,industrial inspection,security,surveillance,defense entertainment due to their diverse and significant benefits.However,in the field of military aviation the medium because of the presence of disturbed media such as atmosphere can make the wavefront distortion of the target occurs during the imaging process and the image on the CCD target is distorted and blurred.Atmospheric disturbance is the key factors influencing the integrated 3D imaging.So how to reduce the influence of atmospheric turbulence on the quality of integral stereoscopic image,it is of great practical significance to explore an integral stereoscopic imaging method suitable for atmospheric turbulence.In this paper,it combines advantages of integral image and lucky image,and the lucky integrated imaging model is proposed,firstly.A series of work has been done around the lucky integrated imaging technology:First,in order to solve the phase distortion are caused by the phase and amplitude changes by atmospheric turbulence.On the basis of integrated imaging,we introduced the lucky imaging technology and first proposed the lucky integrated imaging model.The phase fluctuation of atmospheric turbulence is simulated with phase screen in von-Karman power spectrum.Next,computer simulation experiments are carried out around the lucky integrated imaging model.To established the lucky integral imaging capture system in atmospheric turbulence,and capture a lot of image acquisition.Then,to process these image to select "lucky image" using phase evaluation methodology.Using these "lucky image" under different angles to reconstruct 3D image.The simulation res results show that the proposed method is feasible and effective.Last,on the basis of the lucky integral imaging technology,the model is further optimized.The reconstruction results have a better effect.And you can choose different processing methods according to the requirements of different applications.
