Problems solved by technology

At present, most systems only focus on the reconstruction of 3D scenes based on point cloud data, but after reconstruction, it is rare to reprocess and roam the key objects in the scene
In addition, most 3D scene roaming systems cannot be automated, and many require special processing software such as Photoshop for scene processing, or require staff to write scripts to set paths, which greatly increases the workload of staff. and extremely difficult to operate
In order to achieve a better roaming effect, the staff needs to spend a lot of time on early learning

Embodiment Construction

[0018] The present invention will be described in detail below in conjunction with the accompanying drawings. However, it should be understood that the accompanying drawings are provided only for better understanding of the present invention, and they should not be construed as limiting the present invention.

[0019] Such as figure 1 As shown, the establishment method of the point cloud-based three-dimensional scene roaming system provided by the present invention includes the following contents:

[0020] 1. Scene control: read the 3D scene point cloud data as the input data of the scene control, and draw the 3D scene based on the input data.

[0021] After obtaining the point cloud data of the Leica ScanStation C10 3D laser scanner, the scene can be calibrated using LeicaCyclone, so that the final 3D scene point cloud data can be obtained. The 3D scene point cloud data is used as the input data for scene control. The point cloud data file is in .pts format, and each line c...

Abstract

The present invention relates to a method for establishing a point cloud-based three-dimensional scene roaming system, which is characterized in that it includes the following contents: step 1) reading three-dimensional scene point cloud data as input data, and performing three-dimensional scene rendering based on the input data; step 2) Add and edit hotspot information in the 3D scene; step 3) interact with the drawn 3D scene and the top view of the 3D scene corresponding to the drone aerial photography, set the roaming path, and realize the 3D scene roaming. The invention can help people intuitively understand the three-dimensional scene, and the staff only need to set a simple path to roam the scene.

Description

technical field [0001] The invention relates to a method for establishing a point cloud-based three-dimensional scene roaming system, and relates to the technical fields of point cloud-based three-dimensional reconstruction technology and computer graphics. Background technique [0002] We live in a three-dimensional world, and each object has attributes such as its position, shape, and color in three-dimensional space. The traditional methods of recording 3D world information include drawing, taking pictures, etc., but these methods of recording 3D scenes are slow, the information that can be recorded is limited, and they are all 2D data, which is not intuitive enough. With the rapid development of 3D laser scanning technology, 3D scene reconstruction based on point cloud data has received more and more attention. Three-dimensional laser scanning equipment can scan objects of any shape, and has the characteristics of high speed, high precision, full automation, and digitiz...
