基于计算机视觉图像精密测量的关键技术分析

Precision measurement based on computer vision image analysis of the key technologies

随着国家基础建设的不断深入,建筑物在尺寸方面的精度要求也是越来越高,这样就给测量工程带来了很多的要求。在以往的测量中,大多采用是人工测量的方式,在误差的控制上选择的是多次测量,反复操作,再将多次测量的结果进行加权,最终得到相对准确的测量数值。这种方法在一定程度上是操作十分复杂,精度还很难达到设计要求,所以我们在测量工程中引进了计算机视觉图像精密测量这样的一个概念,下面我们就如何通过计算机视觉图像的关键技术进行有效的观测测量来进行讨论。

With the deepening of national infrastructure,buildings in size precision requirements are getting higher and higher,so give Surveying Engineering brings a lot of requirements.In the conventional measurement,they use a manual measurement mode,the error is selected on the control of several measurements,repeated operation,and then weighting the results of several measure ments,to obtain relatively accurate measurement of the final value.This approach is to some extent a very complicated operation,accuracy is difficult to meet the design requirements,so we introduced the measurement engineering computer vision image preci sion measuring such a concept,let on how visual images via a computer key technologies the observational measurements dis cussed.
