放样

The method use was appropriate both simplifies the lofting procedure and to be possible to increase the lofting accurate and the reliability.

方法使用得当既简化了放样程序又可增加放样的准确和可靠性。

The measuring data after pre-processing was fitted with NURBS curve with constructing the non-uniform node vector using the method of cumulating chord length and optimizing the rights of NURBS curve restrictively. The formula of surface skinning which can be realized by programming was proposed on the basis of the foundation formulas in existence, then NURBS curves was skinned to gain the corresponding NURBS surface.

对经过预处理后的测量点数据，通过采用累积弦长法构造非均匀节点矢量和对权因子的约束优化，进行测量点数据的NURBS 曲线拟合，在现有基本公式的基础上推导出了可以编程实现的曲面放样公式，对得到的NURBS 曲线进行放样处理，最终得到了测量点数据的NURBS 曲面。

According to road designing data of mileage,coordinate,azimuth angle of tangent or straight line,curve radius,the length of spiral line from main point of curve or straight line starting point,we can calculate the coordinates of center line points and boundary line point s in any form of road under the same coordinate system.

The calculation method commonly used for positioning and setting-out angle of piling survey of high-piled wharf is briefly introduced.

简述了高桩码头沉桩施工测量定位及其放样角度常用的计算方法，探讨了用Excel电子表格完成放样角度计算的新途径。

Various construction processes and setting-out aspect is closely linked with the construction, it works if it is a guiding beacon and the people, must therefore to protect the accuracy and the accuracy of setting out, otherwise you will miss does make a lot to thousands of miles to work with it is difficult to assess the economic, quality and credibility of the loss.

工程施工的各个工序和环节都与施工放样息息相关，它好像是工程施工的灯塔和指路人，所以一定要保障放样的精确性和准确性，否则就会失之毫厘，谬以千里，给工程带来难以估量的经济、质量和信誉损失。

After the introduction of S750, only the standard linear design documents through the SD card or USB data cable into the S750, make lofting lines can accurately indicate the location of lines in the field, but also in the setting-out data interface Acquisition of high-precision.

在采用S750后，只需将标准的线型设计文件通过SD卡或USB数据线导入到S750中，进行线路放样，既可精确地指示出线路在实地的位置，还可在放样界面进行数据的高精度采集。
