Description

The measurement of large scale structure abnormity body construction and accuracy control method

Technical field

The present invention relates to the realm of building construction, the measurement of specifically a kind of special-shaped body construction of large scale structure and accuracy control method.

Background technology

Traditional large scale special-shaped body construction surveying setting-out mainly uses AutoCAD softwares to contour curve progress etc. point segmentation, by the positioning of each extreme coordinates, is attached using rounding off curve.This method is easy to operate, it is easy to which scene realizes that shortcoming is exactly that the radian of contour line is difficult to control to, and requires higher in large scale special-shaped body construction profile, is difficult to popularization and application in high-rise, Super High opposite sex building, quality control, Cost Control Target are difficult to.

The content of the invention

It is an object of the present invention to convenience of calculation, the measurement of the special-shaped body construction of large scale structure of strong applicability and accuracy control method.

In order to achieve the above object, the present invention is realized in:

A kind of measurement of the special-shaped body construction of large scale structure and accuracy control method;Including

Step 1, measured building structure outline is surveyed and drawn, one group of original coordinates point data of acquisition;

Step 2, measured building structure outline, which is carried out curve fitting, using common least square method or Orthogonal Least Square principle by Matlab softwares calculates and obtains each coordinate points gross data of measured building structure outline;Wherein, by the requirement of control accuracy, common least square method is to make the residual sum of squares (RSS) of curve in the Y direction minimum, and Orthogonal Least Square make it that the residual distance error quadratic sum for prolonging orthogonal direction is minimum;

Step 3, using two original coordinates point datas obtained by step 1, curvature estimation is carried out by curve equation, the actual curvature and actual curvature radius of measured building structure outline is obtained, and is contrasted with step 2 the data obtained;

Step 4, using total powerstation, multifunctional calculator the arbitrary coordinate for being measured building structure outline is selected, calculated and setting-out;

Step 5, obtain using step 2 data that curve matching obtained curvature estimation is carried out by curve equation and standard curvature radius is obtained, precision check, control are carried out to the surveying setting-out of building outline by standard curvature radius.

This accuracy control method its measurement, calculate easy, a curve matching is the coordinate data that can obtain arbitrfary point, and this measuring method is practical, and any obform body structure can all be promoted the use of;And curve precision controlling is on good grounds, very high precision can be obtained.

Embodiment

The present invention is further illustrated below by way of specific embodiment.

A kind of measurement of the special-shaped body construction of large scale structure and accuracy control method;Including
