衍射光学光束整形元件设计
目标:在透镜后焦面上实现图形的光强分布
实现:
1、波长、衍射光学元件口径、形状、入射波前、二维目标分布及尺寸等都可自行设定;
2、对相位进行8台阶量化,重新计算;
3、更换输出面的采样间隔,重新计算。(Design of Diffraction Optical Beam Shaping Element
Objective: To realize the intensity distribution of the pattern on the focal plane behind the lens.
Realization:
1. Wavelength, aperture, shape, incident wavefront, two-dimensional target distribution and size of diffractive optical elements can be set by themselves.
2. The phase is quantized by 8 steps and recalculated.
3. Replace the sampling interval of the output surface and recalculate it.)

Advanced_extracting_algorithm_for_edge_feature_poi
: 对一种基于图像几何重心的特征点提取算法进行了改进 改进后的算法可以提取任何边缘线上凹凸处的特征点 其基本
思想是,首先提取图像的边缘轮廓线,计算封闭边缘线和非封闭边缘线的几何重心 然后以重心为极点,对边缘点极坐标化,形成
幅角-极径曲线,在该曲线上寻找局部极大极小值点 最后根据局部非极大(小)抑制原则对极大(小)值点进行取舍获得特征点 模
拟结果表明算法计算简单 稳定性好 该方法提取的特征点能准确地反映目标的形状,对目标的识别 跟踪以及三维表面重建等都
具有重要的价值(This paper modifiesakindoffeatureextractingalgorithmbasedonimageedge.First, imageedgeoutlineisextracted.
