Quantitative evaluation method for perpendicularity of building structure

Abstract

The invention provides a quantitative evaluation method for perpendicularity of a building structure and aims to solve the technical problems of complex measurement process and low measurement efficiency in the prior art. The method comprises the following steps of: firstly, acquiring a building image by using a mobile terminal device; secondly, performing outer contour line sharpening processing on the building image by utilizing Image-J software to obtain a building outer contour line; then, acquiring coordinates of the outer contour line of the building through the Image-J software, and outputting coordinate values of sampling points; finally, calculating the vertical length of the outer contour line of the building and the horizontal coordinate difference value of the outer contour line of the building in the same vertical direction , and calculating the perpendicularity of the building according to the vertical length and the maximum horizontal coordinate difference value. According to the invention, the perpendicularity measurement of the building structure is converted into mobile phone terminal measurement, so that the limitation of a field actual environment is reduced; according to the method of the invention, image statistical analysis is carried out by means of image processing software, the perpendicularity of the building structure is quantitatively evaluated in real time, the labor cost is saved, the efficiency is high, and the precision is good.
