Embodiment Construction

[0016] A specific embodiment of the present invention will be described in detail below in conjunction with the accompanying drawings, but it should be understood that the protection scope of the present invention is not limited by the specific embodiment.

[0017] In this application document, unspecified component models and structures are all prior art known to those skilled in the art, and those skilled in the art can set them according to the needs of the actual situation. In the embodiments of this application document No specific restrictions are made.

[0018] Specifically, such as figure 1 As shown, the embodiment of the present invention provides a method for measuring civil engineering buildings, including the following steps:

[0019] First, set the panoramic camera at any point on a plane with a set height in the room. A room is a space, which can be regarded as composed of multiple horizontal planes stacked in the longitudinal direction. Therefore, each horizon...

Abstract

The invention discloses a civil engineering house measurement method, which comprises the steps that a panoramic camera performs circumferential rotation and shoots a panoramic image of the point in the circumferential direction, and the midpoint of the panoramic image is used as the coordinate of a shooting point in the panoramic image; extracting all intersection lines of the wall surface and the ground from the panoramic image, obtaining coordinates of each pixel point of each intersection line in the panoramic image, and obtaining the length of each intersection line in the panoramic imageaccording to the coordinates of each pixel point of each intersection line in the panoramic image; respectively calculating the coordinates of the shooting point in the panoramic image and the coordinates of each pixel point of each intersection line in the panoramic image, and calculating the distance from the shooting point to each intersection line; searching a proportion corresponding to eachintersection line in a database according to the distance from the shooting point to each intersection line; obtaining the actual length of each intersection line according to the length of each intersection line in the panoramic image and the corresponding proportion; according to the actual length of each intersecting line, the area of the room is obtained through calculation.

Description

technical field [0001] The invention relates to the field of building measurement, in particular to a civil engineering building measurement method. Background technique [0002] After the construction of the house is completed, the area of ​​the house is usually measured. The usual method of measurement is to measure the area of ​​each room separately, and then add the areas of each room to get the area of ​​the house. When measuring the area of ​​a room, the size of the wall is usually measured with a measuring ruler, and then the area of ​​the house is calculated through a mathematical formula. Although such a measurement method is very simple, easy to operate, and has the lowest cost, there are often certain errors when using a measuring ruler for measurement. The error of the actual area is larger. Contents of the invention [0003] The purpose of the present invention is to overcome the problems existing in the above-mentioned prior art, and to provide a method for...
