Computation of microimages for plenoptic display. We report a new algorithm for the generation of the microimages ready for their projection into an integral imaging monitor. The algorithm is based in the transformation properties of the plenoptic field captured with an array of digital cameras.

According to the Nyquist sampling criteria, the tracks should be evenly spaced and the number of the tracks is large, however they are hard to achieve in real situation. Simulation of signal reconstruction based sparse flight downward-looking 3D imaging SAR.
Aimed at continuous scene imaging, this paper utilizes signal reconstruction method to eliminate random phases of scatter cells and reduce signal bandwidth, to achieve downward-looking 3D imaging in the condition of sparse flight for array SAR. With the sampling method of repeat flight such as 7 dense flights and 4 sparse flights with sampling criteria of [1 1 1 Two test systems are developed and present, with architecture explanations. Xilinx development tool ISE These methods can effectively reduce the antenna elements in 3D imaging systems. Compared to the conventional methods, the proposed method requires a smaller number of antenna elements.
It is demonstrated through simulations and experience. We show that a small number of cameras can produce the microimages for displaying 3D scenes with resolution and parallax fully adapted to the monitor features. It can realize 3D imaging with unevenly spaced passes, and the spaces of adjacent tracks can be exceed the Nyquist sampling distance, and the number of passes is reduced. First we analyze the spectrum estimation method for MB-SAR 3D imaging, and obtain the sampling requirement for the passes according to Nyquist sampling criteria.

Chirp stepped-frequency signal is transmitted in the interferometric inverse synthetic aperture radar system. Before the processing of 3D imaging, the strong ground clutter has been removed by using a new chirp stepped-frequency signal format. Then the 3D images of the ground moving targets can be achieved according to the principle of the interferometric 3D imaging. An improved IDW method for linear array 3D imaging sensor. The linear array 3D imaging sensor uses a common optical path system to acquire image and point cloud data at the same time. The registration of these two types of data is realized by the common optical axis alignment and time synchronous control system.
Since the image and point cloud data have different sampling frequencies; the process of generating colored point cloud needs to interpolate the point cloud. According to the principle of IDW method and the characteristics of the data acquired by the linear array 3D imaging sensor, this article proposes an improved IDW method by selecting the power parameter adaptive to the topography and designing a topographic factor in the weight calculating.
The experiment results show that the improved IDW method improves the interpolation accuracy.
