Description

Technical Field

[0001] The present invention relates to the technical field of karst cave landscape design, and particularly to a karst cave landscape design method, system, device and storage medium based on three-dimensional scanning. Background Art

[0002] As a unique natural landscape, karst caves have complex geological structures and rich ornamental values.

[0003] However, since traditional karst cave landscape design mainly relies on manual measurement and drawing, the following problems exist:

[0004] 1) Difficult measurement: This method is time-consuming and laborious, and the internal environment of karst caves is complex. Especially for northern karst caves, with diverse topographies and landforms, it is difficult for manual measurement to comprehensively and accurately obtain the spatial data inside the karst cave, and errors are likely to occur; 2) High safety risks: The inside of karst caves is dimly lit, the ground is slippery, and there are dangers such as cave-ins. Manual measurement poses significant safety hazards; 3) Low design efficiency: The data obtained by traditional methods has low accuracy and is difficult to meet the requirements of refined design. The design process is time-consuming and laborious. Therefore, designing karst cave landscapes based on the karst cave data obtained in this way will cause problems with the inaccuracy of karst cave landscape data, and in actual construction, it will lead to problems with the precise matching of karst caves and karst cave landscape designs.

[0005] In summary, the existing methods for measuring the inside of karst caves are prone to large errors in the measurement data of the inside of karst caves, which will lead to problems with the precise matching of karst cave landscapes and karst caves during actual construction. When the karst cave and the karst cave landscape cannot be precisely matched, it will seriously affect the overall perception of tourists of the karst cave landscape. Summary of the Invention

If they match, the design of the original karst cave landscape is completed; otherwise, the operations of steps S3 to S6 are executed.

[0023] Further, in an embodiment of the present invention, in step S4, for the karst cave images of the landscape design of multiple independent regions, numbering and positioning are specifically performed as follows:

[0024] After numbering the karst cave images of the landscape design of multiple independent regions in sequence, based on the numbering sequence, positioning is performed at the edges of the karst cave images of the landscape design of multiple independent regions.

[0035] The present invention solves the problem that the existing measurement methods may cause inaccurate matching between karst caves and karst cave landscapes. The specific beneficial effects include:

[0036] 1. A method for karst cave landscape design based on 3D scanning. In the existing methods for measuring the interior of karst caves, the measurement data of the cave interior is prone to large errors, which may lead to problems in the accurate matching of karst cave landscapes during actual construction. To solve the above technical problems, the present invention uses a data acquisition method suitable for karst caves with complex internal environments, especially those with diverse terrains and landforms. After landscape design based on the constructed 3D digital model of the karst cave and splitting the 3D digital model of the karst cave with landscape designs for each region, the 3D digital models of the karst cave landscape designs for multiple independent regions obtained after splitting are all converted into 2D images of the karst cave landscape designs for multiple independent regions. Then, numbers and fixed points are assigned to the 2D images of the karst cave landscape designs for multiple independent regions. During the actual construction process, accurate registration of the karst cave and the karst cave landscape can be completed;

[0037] 2. A method for karst cave landscape design based on 3D scanning. In the prior art, when converting the 3D digital model of the karst cave with landscape designs for each region into 2D images of the karst cave with landscape designs for each region, due to the limited resolution of 2D images, the problem of being unable to fully restore the details of the 3D model may occur, and the converted 2D images are prone to losing the original accuracy and details of the 3D model. To overcome the above technical problems, the present invention first splits the 3D digital model of the karst cave with landscape designs for each region into 3D digital models of the karst cave landscape designs for multiple independent regions, and then converts the 3D digital models of the karst cave landscape designs for multiple independent regions into 2D images of the karst cave landscape designs for multiple independent regions. In this way, as many details as possible can be retained when converting the 3D model into a 2D image;

[0038] 3. A method for karst cave landscape design based on 3D scanning. In the prior art, when directly referring to the 2D images of the karst cave landscape designs for multiple independent regions for construction, due to possible errors or noises in the 2D data from different perspectives, the alignment and registration of 2D data in 3D space may be inaccurate. To overcome the above technical problems, the present invention assigns numbers and fixed points to the 2D images of the karst cave landscape designs for multiple independent regions, and performs landscape construction on the original karst cave based on the 2D images of the karst cave landscape designs for multiple independent regions after numbering and fixing points. It can achieve accurate alignment and registration of 2D data from multiple perspectives, thereby completing the design of the original karst cave landscape;

[0039] A method for karst cave landscape design based on 3D scanning according to the present invention obtains high-precision spatial data by performing 3D scanning on the interior of the karst cave, constructs a 3D model of the karst cave, and performs landscape design on this basis, improving the efficiency and accuracy of the design and reducing safety risks.

[0040] The above and / or additional aspects and advantages of the present invention will become apparent and be readily understood from the following description of embodiments in conjunction with the accompanying drawings, wherein:

[0043] Figure 3 is the flowchart of the landscape design based on the three-dimensional model described in Embodiment 1. Specific Embodiments

[0044] The following will clearly and completely describe various embodiments of the present invention in conjunction with the accompanying drawings. The embodiments described by referring to the accompanying drawings are exemplary and are intended to explain the present invention, and should not be construed as limiting the present invention.

[0045] Embodiment 1. A method for karst cave landscape design based on three-dimensional scanning according to this embodiment includes the following steps:

[0046] Step S1, perform three-dimensional scanning on the interior of the original karst cave to obtain a point cloud data set;

[0047] Step S2, after preprocessing the point cloud data set, use the preprocessed point cloud data set to construct a three-dimensional digital model of the karst cave;

[0048] Step S3, perform landscape design on each area based on the constructed three-dimensional digital model of the karst cave. Based on each area of the landscape design, split the three-dimensional digital model of the karst cave with the landscape design of each area into three-dimensional digital models of the landscape design of multiple independent areas;

[0049] Step S4, convert the three-dimensional digital models of the landscape design of multiple independent areas into three-dimensional digital models of the landscape design of multiple independent areas, and number and fix points for the three-dimensional digital models of the landscape design of multiple independent areas;

[0050] Step S5, perform landscape construction on the original karst cave based on the three-dimensional digital models of the landscape design of multiple independent areas after numbering and fixing points, thereby completing the design of the original karst cave landscape.

[0051] In the prior art, manual measurement of the internal data of karst caves is usually adopted, which often easily causes errors in the measurement data, resulting in errors in the karst cave landscape design. During the actual construction process, it is easy to cause the problem that the karst cave does not match the karst cave landscape.

[0052] To solve the above technical problems, as Figure 3As shown in the figure, this embodiment proposes a karst cave landscape design method based on 3D scanning. This design method uses a data acquisition method suitable for karst caves with complex internal environments, especially those with diverse terrains and landforms. After landscape design based on the constructed 3D digital model of the karst cave and splitting the 3D digital model of the karst cave with landscape design for each area, the 3D digital model of the karst cave with landscape design for multiple independent areas obtained after splitting is converted into karst cave images with landscape design for multiple independent areas. And the karst cave images with landscape design for multiple independent areas are numbered and fixed-pointed. During the actual construction process, accurate registration of the karst cave and the karst cave landscape can be completed.

[0053] It should be noted that if the 3D digital model of the karst cave with landscape design for each area is directly converted into a karst cave image with landscape design for each area, during the conversion process, due to the limited resolution of the 2D image and the problem of being unable to fully restore the details of the 3D model, it is easy for the converted 2D image to lose the original accuracy and details of the 3D model. To solve the above technical problems, in this embodiment, the 3D digital model of the karst cave with landscape design for each area is first split into 3D digital models of the karst cave with landscape design for multiple independent areas, and then the 3D digital models of the karst cave with landscape design for multiple independent areas are all converted into karst cave images with landscape design for multiple independent areas. In this way, it can be realized that the 3D model is converted into a 2D image while retaining as many details as possible.

[0054] The processes of splitting the 3D model into multiple independent 3D models and converting multiple independent 3D models into multiple independent 2D images in this embodiment are all existing technical means, and will not be elaborated here.

[0055] In addition, if the construction is directly carried out with reference to the karst cave images with landscape design for multiple independent areas, due to the possible errors or noises in the 2D data from different perspectives and the problem that the alignment and registration of the 2D data in the 3D space may be inaccurate. To solve the above technical problems, in this embodiment, the karst cave images with landscape design for multiple independent areas are numbered and fixed-pointed, and based on the karst cave images with landscape design for multiple independent areas after numbering and fixed-pointing, landscape construction is carried out on the original karst cave, which can realize the accurate alignment and registration of 2D data from multiple perspectives, so as to complete the design of the original karst cave landscape.

[0056] The technical means of numbering and fixed-pointing in this embodiment are all existing technical means, and will not be elaborated here.

[0058] In this embodiment, the three-dimensional data acquisition of the karst cave: Use a three-dimensional scanning device suitable for the karst cave environment to scan the interior of the karst cave to obtain the original point cloud data set.

[0059] Due to the complex internal environment of the karst cave and the changeable terrain and landform, in order to obtain the data inside the karst cave comprehensively, a handheld laser scanner is selected, which is more compact and convenient and can better be applied to the scanning of narrow spaces inside the karst cave.

[0060] Scan point by point inside the karst cave according to the planned path to ensure that the scanning coverage rate reaches 100%, and record the scanning parameters.

[0061] Embodiment 3. This embodiment further limits a method for karst cave landscape design based on three-dimensional scanning described in Embodiment 1. In step S2, the preprocessing of the point cloud data set includes the following steps:

[0062] Step S201, respectively remove the noise and outliers in the point cloud data set;

[0063] Step S202, register the point cloud data set after removing the noise and outliers respectively;

[0064] Step S203, after simplifying the registered point cloud data set, the preprocessing of the point cloud data set is completed.

[0065] In this embodiment, as Figure 2 shown, the preprocessing of the point cloud data set includes the following steps:

[0066] Step S201, data import: Import the collected point cloud data into the data processing software.

[0067] Step S202, denoising processing: Use a filtering algorithm to remove the noise and outliers in the point cloud.

[0068] Step S203, data registration: Adopt the ICP (Iterative Closest Point) algorithm to accurately register the data of multiple scanning stations to generate a consistent overall model.

[0069] Step S204, model simplification: Simplify the point cloud data to reduce the data volume, improve the subsequent processing efficiency, and retain the key spatial features at the same time.

[0070] Therefore, in this embodiment, by processing the original point cloud data set, including denoising, alignment, stitching and simplification, a complete three-dimensional model of the karst cave is generated.
