[Other] 论文基于图像恢复在无人机领域的应用与研究 (2) DL : 0: 由于无人机在航拍时会受到相对运动、姿态变化、光学环境、机械振动等因素的影响，导致所拍图像退化。本文使用MATLAB对无人机航拍图像退化过程进行了仿真实验，根据图像退化的原因建立相应的图像退化模型，把清晰的原图像进行退化处理,然后将模拟出来的退化图像分别使用维纳滤波、约束最小二乘（正则）滤波、Lucy-Richardson迭代非线性和盲解卷积4种不同的复原算法进行恢复，达到复原模糊图像的目的。(The application of UAV aerial photography became more and more widely. As the UAV in the aerial photography would be subject to relative movement, posture changes, optical environment, mechanical vibration and other factors which had resulted in the image degradation. In this paper, I used MATLAB to simulate the degradation process of UAV aerial image. According to the reason of image degradation, I established the corresponding image degradation model and the original image was degraded. Then simulated degraded images respectively used the wiener filter, constrained least squares (regular) filtering, Lucy - Richardson iterative nonlinear and blind convolution four different restoration algorithms for recovery, achieved the goal of restoring blurred image.)

[Other] 大气湍流 DL : 0: 在多层共轭自适应光学中，采用相位屏模拟湍流的大气，用以研究湍流大气的最佳分层，确定层边界位置。文中提出了湍流大气的实验室相位屏模拟原理及相位屏个数与边界确定的仿真算法。仿真结果表明。可使用较少的相位屏模拟多层大气湍流，从而使系统结构简化。(In the multi-layer conjugate adaptive optics, the phase screen is used to simulate the turbulent atmosphere, so as to study the optimal stratification of the turbulent atmosphere and determine the boundary position of the layer. In this paper, the principle of phase screen simulation in turbulent atmosphere and the simulation algorithm of the number and boundary of phase screens are proposed. The simulation results show that. A few phase screens can be used to simulate multi-layer atmospheric turbulence, thus simplifying the system structure.)
