Problems solved by technology

In order to restore the real situation of the construction site as much as possible, it is necessary to take as many photos as possible each time, and to standardize the naming of the photos in the later stage, for example, it is necessary to clearly indicate which time, which area, which building, which floor, which room And which direction to face, which is very labor-intensive and time-consuming
[0007] 2) It is difficult to restore the same perspective as the photo in the 3D architectural model
The process is quite cumbersome. First, you need to find the nearest saved position point in the 3D model according to the naming convention of the photo, then use the API of the 3D model to switch to the p

Embodiment 1

[0062] A method for comparing a three-dimensional building model with a real scene in the construction engineering industry, see figure 1 , including the following steps:

[0063] S1: Acquiring three-dimensional 360-degree real scene image data;

[0064] Described 360 degree real scene image data comprises 360 degree real scene video and 360 degree real scene photo;

[0065] The 360-degree real-scene video is shot by a user wearing a safety helmet walking on a construction site, and the safety helmet is provided with a 360-degree camera.

[0066] Specifically, the 360-degree real-scene video of this method is captured by a safety helmet + a 360-degree camera. The user needs to wear a safety helmet and walk around each floor of the construction site. As long as the path can cover all areas of the construction site, the details of the entire construction site can be photographed. This minimizes the number of fixed-point photoshoots and reduces the amount of positioning requir...

Embodiment 2

[0099] A kind of 3D building model and real scene comparison system in construction engineering industry, see Figure 5 ,include:

[0100] Acquisition unit: used to acquire three-dimensional 360-degree real scene image data;

[0101] Alignment unit: used to align the 360-degree real-scene image data with the preset three-dimensional building model;

[0102] Linkage unit: used to establish the linkage relationship between the aligned 360-degree real-scene image data and the 3D building model, so that the 360-degree real-scene image data and the perspective of the 3D building model are consistent;

[0103] Comparison unit: it is used to compare the 360-degree real scene image data with the 3D building model under the same viewing angle.

[0104] Preferably, the 360-degree real-scene image data includes a 360-degree real-scene video and a 360-degree real-scene photo;

[0105] Wherein, the 360-degree real-scene video is shot by the user wearing a safety helmet walking on the cons...

Abstract

The invention provides a three-dimensional building model and live-action comparison method and system in the constructional engineering industry. The method comprises the following steps: obtaining three-dimensional 360-degree live-action image data; aligning the 360-degree live-action image data with a preset three-dimensional building model; establishing a linkage relationship between the aligned 360-degree live-action image data and the three-dimensional building model to enable the 360-degree live-action image data to be consistent with the visual angle of the three-dimensional building model; and comparing the 360-degree live-action image data with the three-dimensional building model at the same visual angle. According to the method, the three-dimensional 360-degree live-action image data is compared with the three-dimensional building model, so that the problem of high comparison difficulty caused by different dimensions when the two-dimensional picture is compared with the three-dimensional building model in the prior art is solved, the comparison workload is reduced, and the analysis efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of engineering management, and in particular relates to a method and a system for comparing a three-dimensional building model with a real scene in the construction engineering industry.
