Mounting and positioning method for prefabricated structure incapable of intervisibility
The invention discloses a method for installing and positioning a prefabricated structure incapable of intervisibility, which comprises the following steps of: 1, before installation, finding at least three visual points D1, D2 and D3 for a hidden point P in a prefabricated structure finished product in a backfield, and respectively acquiring the spatial distances L (D1-P), L (D2-P), L (D3-P) and L (D4-P) between the visual points and the hidden point; and 2, in the field structure installation and positioning process, observing the visual points D1, D2 and D3 to obtain three-dimensional coordinates, and calculating to obtain real-time three-dimensional coordinates (Xp, Yp and Zp) in the hidden point installation process according to the spatial distance between the visual points collected in the backfield and the hidden point. According to the invention, the real-time three-dimensional coordinate of the hidden point can be accurately obtained under the condition that measurement cannot be carried out.
本发明公开了一种用于无法通视的预制结构安装定位方法，包括以下步骤：步骤一、安装前，在后场对预制结构成品中隐蔽点P找到至少3个可视点D1、D2、和D3，并分别采集可视点与隐蔽点的空间距离L(D1‑P)、L(D2‑P)、L(D3‑P)、L(D4‑P)；步骤二、在现场结构安装定位过程中，通过对可视点D1、D2、和D3进行观测，得出三维坐标，并根据后场采集的可视点与隐蔽点的空间距离，计算得到隐蔽点安装过程中的实时三维坐标(Xp,Yp,Zp)。本发明实现了无法测量条件下准确得出隐蔽点的实时三维坐标。
