1) parallactic restriction
视差约束
1.
Feature point matching based on bidirectional maximal correlation and parallactic restriction;
基于双向最大相关与视差约束的特征点匹配
2) constraints on disparity distribution
视差分布约束
1.
The constraints on disparity distribution and correlations among disparity vectors were first analyzed, including the temporal correlation among intra-frame disparity vectors and spatial correlation among inter-frame disparity vectors.
基于视差分布约束和视差矢量的相关性,给出了视差估计快速算法。
3) three-view constraint
三视约束
4) projective constrain
透视约束
1.
In this paper, a novel algorithm based on projective constrain for automatic generation of 3D surface model is proposed.
提出了一种基于透视约束利用离散三维空间点重建三维表面模型的方法,该方法充分利用摄影测量 以及激光扫描等三维测量技术中隐含的透视关系,将离散点划分到不同的投影面,在局部利用二维三角网构 网技术构建三角网,然后在考虑局部三角网边缘一致性的基础上组合成整体三维表面模型。
5) constraint adjustment
约束平差
1.
In GPS control survey,as if relevant definition parameter of local independent coordination system were unknown,the constraint adjustment couldn′t adjust,and that can do nothing but can apply coordinate translation method to solve the local coordinate of unknown points;in TGO system,the point calibration is used to solve this problem.
在GPS控制测量中,若未知地方独立坐标系的相关定义参数时,便不能进行约束平差而只能用坐标转换的方法来求取未知点的地方坐标,在TGO系统中用点校正来解决问题。
2.
Hereby,this paper introduced three kinds of known points\' reliability check methods,such as regression analysis,actual measurement baseline comparison and constraint adjustment method.
据此,介绍了GPS控制网已知点可靠性检验的几种方法,主要包括:回归分析法,实测基线比较法和约束平差分析法3种。
6) restrained adjustment
约束平差
1.
A study on the influence of datum points on the precision of restrained adjustment results of GPS engineering networks has been carried out on the basis of examples.
通过实例研究了基准点点位误差对ＧＰＳ工程网约束平差结果精度的影响规律，提出了一种检验基准点可靠性的简便可行的方法。
补充资料：电视差转台
利用外差法改变接收到的电视信号的载频并经放大再转发出去的装置。可使电视覆盖面增大，在山顶设差转台，可使山背后能收到电视节目。设备简单，能几次差转，起到中继接力作用。
