The key problem of the optical design of f - theta lens is to achieve the flat field image with high performance as its working area becomes large 随着工作面积的增大,设计f - theta镜头的关键是要在大的像平面内获得高质量的平场像点。
First , the elements of the image navigation are analyzed and the coordinate systems are defined . with projection relation of perspective projection and epipolar geometry considered , essential matrix is derived 考虑导航相机采用透视投影模型时的空间点在像平面上的投影关系,结合极线几何的性质,给出了本质矩阵的定义式。
We designed the beacons plane , used proper infrared ccd and designed real hardware circuite based on the dsp , which can be used to simulate and experiment on precision positioning algorithm by computer 设计了适当摄影测量算法的信标点平面,采用了红外波段的ccd ,以dsp为核心器件设计了信标点像平面位置坐标提取的硬件电路。
( 7 ) the experiment of the hot - image from phase scatterer in n31 nd - glass is carried out . the experimental results are found to be in good agreement with previous analytical and numerical results ( 7 )开展了n31钕玻璃介质中位相型衍射物形成热像规律的实验研究,得到了热像的位置、强度及像平面的能流分布等结果,结论与理论模拟结果吻合较好。
The fundamental of this model is assuming that the change of the projection of moving objects on the image plane can be modeled by an affine transformation . then these parameters of regions " motion will be obtained from this model 建立模型的主要根据是假设所分析的目标在像平面上的投影随着时间的推移所发生的演化过程可以用一个仿射运动模型来模拟。
