缩短

the digitized mapping technique is to combine the field data collection system with the computer assisted mapping system in surveys by computer technology.it aims to realize the information collected and processed digitally and automaticaity.the digitized mapping technique can cut short the working time,lighten the labor intensity and enhance the precision of the productions.the system consists of three parts,such as data input,data processing and data output.the survey-record digitized mapping technique is widely used in the digitized mapping working pattern.for its superiority over traditional plane-table mapping in accuracy and efficiency,the large scale digital mapping is becoming more and more popular.compared with traditional analogue mapping,digital mapping has more quality control pivotai points,and its contents and methods are more complex.with the appearance of new technology gps ,the coordinate of different levels controlling points may be surveyed in high precision and it has been applied widely in topographic survey.the operation process of gps electronic tachometer is introduced and its application in topographic survey is br

计算机应用论文，计算机论文， rtk ，全站仪，数字测图，地形测量， gps论文摘要：数字测图是在测量工作中利用电子计算机技术将野外数据采集系统与内业机助制图系统相结合，其目标是实现信息采集处理的数字化、自动化、信息化。数字测图可以缩短作业时间，减轻劳动强度，提高成果精度。数字测图系统主要由数据输入、数据处理和数据输出3部分组成，数字测图作业模式中测记式数字测图应用最为广泛。大比例尺数字测图正以其测图精度高，成图速度快等优势逐步的取代传统的，以平板仪为主的模拟测图。与传统的模拟测图相比，数字测图的质量控制关键点更多、内容与方法更为复杂。gps 新技术的出现，可以高精度并快速地测定各级控制点的坐标，在地形测量中已得到广泛地应用。本文介绍了gps 配合全站仪的作业流程，简要阐明了其在地形测量中的应用。在利用实测数据成图的过程中，解决一些常见的问题，并给出解决的办法及依据，同时给出一些有益的结论，以适应实际使用的需要。

The adoption of CTP technology not only greatly simplifies platemaking process short seihan time (a set of color plate time required for conventional seihan time only 1/3), and reduce the phenomenon of dot gain, so that hihglights and darkened parts of mesh point loss and a significant reduction in the power grid, which improves the ability to copy from.

采用CTp技术，不仅大大简化了制版工艺，缩短了制版时间（出一套彩色版材所需时间仅为传统制版时间的1/3），而且减少了网点增大现象，使高光与暗调部位的网点丢失与并网大为减少，提高了印版的复制能力。

In the field of the CAD application, have already exceeded the junior stage throwing away drawing board , two-dimensional plotting, 3 D design that the application having already reached 70 ? G-- 89 ? G , softwares such as PRO/E , UG , CIMATRON is very common at present. Adopt the quick-cutting processing technology commonly 2, for shortening a manufacturing cycle , improving marketplace competition. 3, the fleetness molding technology and the fleetness moulding technology gain common application.

在CAD的应用方面，已经超越了甩掉图板、二维绘图的初级阶段，目前3D设计已达到了70℅--89℅，PRO/E、UG、CIMATRON等软件的应用很普遍。2）、为了缩短制造周期，提高市场竞争力，普遍采用高速切削加工技术。3）、快速成型技术与快速制模技术获得普遍应用。

It first choose a mask with a suitable size in the edge image, the local PCA is performed to obtain the principal direction of the mask. The chosen polar angle in Hough transform is limited in a small range emphasizing particularly on the statistical disciplinarian of all principal directions, so it speed up the search time by reducing the range of .

首先在边缘图像范围中选取合适大小的掩膜，通过局部PCA获得支持集内像素点的主元方向；侧重依据所有掩膜内主元方向信息的统计规律来约束Hough变换的极角选择范围，通过缩小参数选择范围大大缩短搜索时间。
