一种用于BIM模型坐标系转换至工程坐标系的方法

A method for converting a BIM model coordinate system to an engineering coordinate system

在工程测量技术无法突破既有发展模式的情况下,BIM技术的出现使得测量技术的发展发生了质的改变。BIM模型中包含大量的测量信息,但由于建模时所选轴网位置具有随机性,模型特征点数据读取后还需要进行坐标系转换。本文基于BIM技术的特点及对传统坐标系转换方法的研究,研发了一种用于BIM模型坐标系转换至工程坐标系的方法。

Under the circumstance that engineering surveying technology cannot break through the existing development mode,the emergence of BIM technology makes the development of surveying technology change qualItatively.BIM model contains a large amount of measurement information,but due to the randomness of the selected axis network position during modeling,the coordinate system transformation is also needed after the data of the model feature points are read.Based on the characteristics of BIM technology and the research on the traditional coordinate system conversion method,this paper develops a method for converting the BIM model coordinate system to the engineering coordinate system.
