point image meaning in English
点像
点象
Examples
- Meanwhile , we put forward symmetric correction to resolve inherent error cumulation of point - by - point imaging modality
同时进一步提出对称校正的方法以解决逐点成像法固有的误差累积。 - Since the starry heaven is rotating from east to west , exposure time has to be limited in order to obtain a point image . the limiting exposures are as follows
由于星空不断由东向西转动，若要保持星点在底片上呈点状，最长曝光时间如下： - The comparision of monte carlo simulation result and macro statistic simulation result shows the superiority of the former . then , an improved point - by - point imaging method based on the line - scanning energy spectral data is proposed
并通过蒙特卡罗法模拟结果与宏观统计法模拟结果的比较，表明了该方法的优越性。 - Regular point images of lcd are projected to the measured surface . the images modulated by the surface are received by binocular vision sensor . a special image processing software is developed to deal with the lcd images
系统利用液晶投射空间规则编码点图案到被测曲面，由双目传感器接收经曲面调制的测量图像，经专用设计的图像处理软件，采用粗、细匹配技术精确获得特征匹配点，利用视觉技术得到三维数据点阵。 - On this basis , the error theorem is obtained which divides the hausdorff distance between the original image and reconstructed image into two control parts . the fixed point of each contraction mapping is introduced , the fixed - point image ( which is tiled by all the fixed points ) is selected as an initial image when decoding , and is proved to be a good estimation of the attractor of the ifs
在此基础上，得到误差定理，将原始图像与迭代图像间的hausdorff距离分为两个控制项，并提出基于选择初始图像的分形图像压缩方法，引入不动点图像，解码时选择不动点图像为初始图像，并证明不动点图像是迭代函数系统的吸引子的一个较好的近似。
