Problems solved by technology

However, due to the complexity of the construction site and the large number of building structures, it is difficult to rely on a single reference point to complete the measurement work. In the actual operation process, it is often necessary to perform multiple reference transformations, resulting in low measurement efficiency. Transformation will lead to significant error accumulation, resulting in a decrease in the final measurement accuracy, which is not conducive to accurately grasping the real data of the building

Embodiment 1

[0046] This embodiment provides a building size measurement system for measuring building 3 size data, such as Figures 1 to 3 As shown, it includes a target 2 and a visual detection device 1 corresponding to the target 2, the target 2 is set on the point to be detected of the building 3, the target 2 is a polyhedral structure, and / or the direction of the target 2 in each direction The shape is different, the size of each direction of the target 2 is different, and each direction of the target 2 has prominent marks that are easy to determine. The visual detection device 1 is set on any reference point far away from the building 3. The visual detection device 1-1 in the figure , The visual detection device 1-2 is a visual detection device 1 arranged at different positions. It should be noted that, in the installation process, the center of gravity of the target 2 can be, but not limited to, correspond to the point to be detected of the building 3, and the signal emission point ...

Embodiment 2

[0056] This embodiment provides a measurement method based on the building size measurement system in Embodiment 1, comprising the following steps:

[0057] S1. Make the target 2 correspond to the point to be detected of the building 3, that is, set the target 2 at the point to be detected of the building 3, preset multiple feature points on the target 2, and obtain each feature point of the target 2 the distance between;

[0058] Specifically, such as Figure 5 As shown, when the target 2 is set as a cube, the position of the target 2 is adjusted so that the bottom surface of the target 2 is parallel to the horizontal plane; multiple feature points are preset on the target 2. In this embodiment, the target 2 is set A plurality of vertices of is a feature point (A point, B point, C point, D point, E point, F point), and the distance k between the adjacent feature points of the target 2 is obtained;

[0059] S2. Make the visual detection device 1 correspond to any reference p...

Embodiment 3

[0090] On the basis of embodiment 2, a kind of building dimension measurement method also comprises the following steps:

[0091] S5. Move the target 2 so that the target 2 corresponds to another point to be detected of the building 3, that is, the target 2 is set on the point to be detected of the building 3;

[0092] Assuming that in Example 2, the target 2 is set at the point O to be detected in the building 3 1 , at this time, the point to be measured is O 1 A Cartesian coordinate system O is established for the origin 1 -XYZ, in the present embodiment, the target 2 is successively arranged at the to-be-detected point O of the building 3 2 and the point to be detected O 3 on, and respectively with the point O to be detected 2 and the point to be detected O 3 As the origin, establish a rectangular coordinate system O 2 -XYZ and O 3 -XYZ, at this time, the point to be detected is O 1 where the coordinate system O 1 -XYZ is used as the reference coordinate system, th...

Abstract

The invention relates to the technical field of building detection, and aims to provide a building size measurement system and a measurement method. The invention discloses a building size measurement system, which comprises a target and a visual detection device. The target is set on a point to be detected of the building, the target is a polyhedron structure, and the visual detection device is set on a reference point. The invention also discloses a method for measuring the size of a building, which includes: making the target correspond to the points to be detected of the building, preset a plurality of feature points on the target, and obtain the distance between each feature point of the target; Make the visual detection device correspond to the reference point; the visual detection device measures the orientation information of each feature point of the target; obtain the first pose of the target relative to the visual detection device. The building size measurement system of the present invention has high measurement efficiency, and can simultaneously realize the measurement of the position and attitude of a certain point of the building to be measured; the building size measurement method can improve the measurement efficiency of the building.

Description

technical field [0001] The invention relates to the technical field of building detection, in particular to a building size measuring system and a measuring method. Background technique [0002] In construction engineering, in order to ensure the quality and dimensional accuracy of the building, it is necessary to measure various geometric dimensions of the building at regular intervals. According to the measurement results, it is determined whether the completed work is qualified, and corresponding adjustments are made to the subsequent stage of the project. The efficiency of its measurement directly affects the construction period of the project, and the accuracy of the measurement determines the quality of the project. [0003] In the prior art, a theodolite is generally used for measurement, and during measurement, other key dimensions of the building structure are measured using a fixed reference point. However, due to the complexity of the construction site and the l...
