二维像 meaning in Chinese
two-dimensional image
Examples
- In computer stereo vision , the primary problem to solve is the relations between the 3d points and the 2d image points
计算机立体视觉中，首先必须解决的都是三维物点与二维像点的对应关系问题。 - In this paper , to probe into key problems of feature extraction , a systematic study is performed not only about understanding and processing radar target image , but also parametric modeling of 2 - d target scattering centers and parameter estimation
围绕这一课题，本文研究了雷达目标二维像的理解与处理，及二维散射中心的建模与参数估计问题。 - Under the high - resolution imaging radar background , extracting electromagnetic scattering features of target from 2 - d radar data , is a task valuable for both theoretical research and practical usage in field of radar target recognition
在高分辨成像雷达体制下，基于雷达目标二维像的散射特征提取，是雷达目标识别领域中一项理论意义与实用价值兼备的课题。 - According to scattering phenomenology , we point out that the commonly used point scattering models fails to accurately describe the complex scattering behavior of real target . for that reason , based on the theory of effective scattering centers , researches are taken on more accurately physical - relevant description of target scattering and on approach that is more effective to characterizing and extracting target scattering features by means of time - frequency analysis and scattering centers modeling
全文以此为线索，以光学区散射中心理论为基础，分别从目标二维像的散焦效应、二维像的时频分析、以及二维散射中心的模型化这三个角度，探讨对目标复杂散射特性进行更为合理的描述和分析，并提取可用于识别的目标结构特征。
