photographic measurement meaning in English

照相测量

Examples

For photographic measurement purposes, a strip of material having a transparency which varies in steps along its length is often used .
在摄影测量中，经常用到一种测试条，它的透明度沿长度方向逐级变化。
The improvement on the process of automatically measuring city buildings is one of the most important problems in the current aerial photographic measurement . an approach to measuring a city building based on its structure information is presented . a city building ' s ideal model is first represented by some independent parameters according to its structure information and some image variants which can induce model parameters are defined , and then the initial value of image variants are acquired by combining all kinds of information in the left and right images . finally the optimal location of the building is found for some certain criteria . an implementation of this method is illustrated on flat - roof and rectangular buildings in detail . the experimental results show that not only the method is more automatic than existing methods but also the precision of measurement can satisfy the acquirement of the current aerial photographic measurement , and confirm the method has a good developmental and applied potential
提高城市建筑物测量过程的自动化程度是目前航空摄影测量研究的主要问题之一.文中提出了一种基于结构信息的城市建筑物测量方法.首先根据城市建筑物的结构信息，用几个相互独立的参数来描述建筑物的理想模型，并定义能推导出模型参数的图像变量，然后组合利用左右图像中各种信息获得图像变量的初始值，最后在一定准则下寻求城市建筑物的最佳测量位置.该文以平顶矩形建筑物为例详细讨论了它的一种实现算法.实验结果表明，这种方法与传统方法相比较，有较高的自动化程度，且测量精度能满足现有航空摄影测量的要求，有较大的发展和应用潜力
Firstly , the expansive soils fissures at test field in zaoyang , hubei province , are observed and counted by sketch and photograph , and expansive samples are by continuous photographic measurement using long - distance - microscope - system in laboratory . generalized model of fissures distribution for unsaturated expansive soils is put forward
首先，在湖北枣阳试验现场，通过手工素描与拍照的方法对膨胀土裂隙进行了观察统计；在室内，利用远距光学显微镜系统对膨胀土裂隙进行了连续拍照观测，建立了非饱和膨胀土的裂隙概化模型。
