Description

Technical Field

[0001] The present disclosure relates to the field of intelligent surveying and mapping technology, and in particular to a method, application system and electronic device for creating a three-dimensional garden model based on intelligent three-dimensional surveying and mapping technology. Background Art

[0002] A garden 3D model is a digital model created using 3D software that can be used to simulate the design and layout of a garden landscape. Through this model, designers can preview and adjust the garden in 3D visualization on the computer, thereby improving design efficiency.

[0003] When making a 3D garden model, you usually need to use 3D modeling software, such as SketchUp, AutoCAD, 3dsMax, etc. These software provide a wealth of modeling tools and material libraries to help designers create realistic garden models.

[0004] When creating a 3D garden model, the designer needs to first plan and design the garden, determine the location and size of each element. Then use modeling software to create a 3D model of each element, and arrange and adjust it according to the design requirements. Finally, add effects such as materials, lighting and shadows to complete the production of the entire garden 3D model.

[0005] The 3D garden model has the following advantages:

[0006] 1. Good visualization effect: Through the 3D model, designers can intuitively see the design effect of the garden, which is convenient for modification and optimization.

[0007] 2. Improve design efficiency: The use of garden 3D models can reduce the workload of manual drawing and calculation in traditional design methods, thereby shortening the design cycle.

[0008] 3. Strong reproducibility: 3D models can be easily copied and modified, making it convenient to compare and select multiple options.

[0009] 4. Environmental protection and energy saving: Through the three-dimensional model of the garden, designers can better control the use of materials and resources, thereby reducing energy consumption and reducing waste.

[0010] In the existing technology, there are three main ways to build a garden 3D model: 3D laser scanning technology, stereo mapping satellite technology, and panoramic true 3D imaging technology. However, these types of technology require too much hardware facilities, need to transport a lot of equipment to the site for assembly, and need to be completed by multiple people, which is inefficient.

[0011] In addition, the existing garden three-dimensional model collects garden three-dimensional data basically at one time, and does not take into account that the garden will be affected by outdoor parameters. Therefore, the garden three-dimensional model is not practical enough. Summary of the invention

[0012] In order to solve the above problems, the present application proposes a garden three-dimensional model creation method, application system and electronic equipment based on intelligent three-dimensional surveying and mapping technology.

[0013] On the one hand, the present application proposes a method for creating a garden 3D model based on intelligent 3D mapping technology, comprising the following steps:

[0014] According to the default flight trajectory, the drone is used to perform three-dimensional oblique photography of the garden area at the same altitude. At the same time, the infrared ranging equipment is used to measure the vertical distance between the drone and the garden below to obtain the three-dimensional mapping data S of the garden:

[0015] S={M,L},

[0016] Where: M is the three-dimensional oblique photography data, L is the vertical height distance between the drone and the garden;

[0017] The three-dimensional mapping data S is transmitted back to the control center through the 5G communication module on the drone based on 5G base station communication;

[0024] The drone follows the flight control route and starts the camera at each flight control point p2 at a vertical height of L2 from the garden below to perform three-dimensional oblique photography of the garden area, and obtains a three-dimensional oblique photography data set Mp of each flight control point p2:

[0025] Mp={Mp1, Mp2, Mp3...},

[0026] Among them, Mp1, Mp2, Mp3.....are the three-dimensional oblique photography data at each flight control point p2;

[0031] The control center monitors in real time and determines whether the vertical height distance L2 between the drone and the garden below at each flight control point p2 satisfies the requirement that the vertical height distance L2 between the drone and the garden below at each flight control point p2 is the same height:

[0032] If not, the corresponding flight control command is issued to correct the flight altitude of the drone at the corresponding flight control point p2;

[0033] If so, give up.

[0034] As an optional implementation scheme of the present application, optionally, when the drone starts to shoot at each flight control point p2 at a vertical height of L2 from the garden below according to the flight control route, and performs three-dimensional oblique photography of the garden area, it also includes:

[0039] As an optional implementation scheme of the present application, optionally, the three-dimensional local model of each relative flight control point p2 includes several:

[0040] At each flight control point p2, a three-dimensional local model is constructed by simulating the three-dimensional oblique photography data acquired at the second level.

[0044] The three-dimensional local models of each relative flight control point p2 are composited at the corresponding flight control point p2 on the three-dimensional garden model to complete the dynamic correction of the three-dimensional garden model;

[0045] After the correction is completed, the garden three-dimensional model is updated and saved in the database.

[0046] On the other hand, the present application proposes an application system for implementing the method for creating a garden 3D model based on the intelligent 3D mapping technology, comprising:

[0047] The drone is used to fly according to the preset flight trajectory and flight control route and the corresponding altitude;

It should be understood by those skilled in the art that the present disclosure can also be implemented without certain specific details. In some examples, means, components and circuits well known to those skilled in the art are not described in detail in order to highlight the main purpose of the present disclosure.

[0078] Example 1

[0079] like Figure 1 As shown, on the one hand, the present application proposes a method for creating a garden 3D model based on intelligent 3D mapping technology, comprising the following steps:

[0080] S1. According to the default flight trajectory, use the drone to perform three-dimensional oblique photography of the garden area at the same altitude, and use infrared ranging equipment to measure the vertical distance between the drone and the garden below to obtain the three-dimensional mapping data S of the garden:

[0081] S={M,L},

[0082] Where: M is the three-dimensional oblique photography data, L is the vertical height distance between the drone and the garden;

[0083] S2, transmitting the three-dimensional mapping data S back to the control center through the 5G communication module on the drone based on 5G base station communication;

[0084] S3, the control center receives and analyzes the three-dimensional surveying and mapping data S, and constructs a three-dimensional model of the garden based on the three-dimensional oblique photography data M of the garden through a three-dimensional simulation modeling application, and saves the three-dimensional model of the garden into a database;

[0085] S4, simulating and constructing a flight plane k of a drone flying at the same altitude on the three-dimensional model of the garden;

[0086] S5, identifying and marking a position point p1 with garden features on the three-dimensional model of the garden, and setting a flight control point p2 corresponding to the position point p1 at a corresponding position on the flight surface k, and marking a vertical height distance L1 between the UAV at the flight control point p2 and the garden below;

[0087] S6. Obtain real-time outdoor flight parameters, lower the vertical height distance L1 between the drone and the garden below at each flight control point to L2, and ensure that the vertical height distance L2 between the drone and the garden below at each flight control point p2 is the same height;

[0088] S7. According to the parameters (p2, L2), the flight control route is regenerated and the corresponding flight control command is sent to the UAV, and the three-dimensional model of the garden is rephotographed and corrected.

[0089] This solution uses drones to capture three-dimensional data of the garden and simulate and construct a corresponding three-dimensional model of the garden. Subsequently, it combines outdoor parameters to perform flight control relative to the garden, reconstructs three-dimensional locations with garden characteristics and uses them to adjust the model of the corresponding location, thereby obtaining a three-dimensional model with garden characteristics, allowing users to better understand the true situation of the garden.

[0090] The 3D garden mapping technology based on drones is an efficient and accurate measurement method. It uses the sensors and equipment carried by drones to quickly obtain oblique images with time and space information, thereby producing a 3D real-life model of the park. By carrying a variety of advanced sensors and equipment such as high-precision positioning and attitude systems and oblique photography cameras on drones, the survey area is measured in all directions without control, and vertical images and oblique images that can be measured on four sides are obtained. The oblique images obtained have the characteristics of full texture, real environment, visualization, browsing, and measurability.

[0091] Based on these oblique images, corresponding software is used for preprocessing, including color adjustment, correction, calibration, mosaic, fusion and other series of processing, to form 3D real-life map data that meets application requirements. This technology provides an effective basic geographic spatial framework for smart parks, with the characteristics of fast, accurate, comprehensive and real-time, which helps to improve measurement efficiency, reduce measurement costs, and provide strong support for garden planning, design, construction, etc.

[0092] In this embodiment, the composition and flight control of the drone are not described in detail, and reference may be made to the flight control operation manual of the existing drone.

[0093] like Figure 2 The following is a schematic diagram of the application system of the present invention. The application process of the system will be described in conjunction with specific embodiments.

[0094] like Figure 3 and 4 As shown, for the garden area that needs to be three-dimensionally mapped, this solution controls the drone to perform three-dimensional oblique photography of the garden area on the flight plane k at the same altitude. The flight trajectory of the three-dimensional oblique photography on the flight plane k is not limited in this solution. The flight trajectory from outside to inside or from inside to outside can be used to obtain the three-dimensional flight measurement data of the garden. At the same time, the infrared ranging equipment carried by the drone is used to measure the vertical height distance of the drone relative to the garden below, and obtain the vertical height distance data of the drone from the garden below.

[0095] The drone uses a 5G communication module to transmit the data collected by the drone back to the control center based on the 5G communication network, including 5G communication base stations and operators.

[0096] Before the drone flies, it is necessary to activate the drone and establish management and communication between the drone and the drone management module in the background. The administrator can manage the flight control of the drone through the management center and monitor the flight status of the drone on the drone management module. The specific implementation and understanding can be combined with the existing flight control of the drone, and this solution will not be elaborated.

[0097] After receiving the 3D data sent back by the drone, the control center can call the 3D simulation system deployed in the background to analyze the 3D mapping data and build the corresponding 3D model of the garden. The specific 3D simulation system deployed is not limited in this solution.

[0098] Using the three-dimensional simulation system, according to the three-dimensional oblique photography data of the garden, the corresponding three-dimensional model of the garden is simulated and constructed. Specifically, the three-dimensional simulation modeling technology can be combined to obtain the three-dimensional model of the garden through simulation modeling and save it in the database to obtain the three-dimensional model of the garden.

[0099] The three-dimensional model of the garden at this time may have differences in local model characteristics, which is different from the actual garden. The local form of the garden may change due to outdoor flight parameters.

[0100] Therefore, the three-dimensional model of the garden has some morphological errors.

[0101] This solution readjusts the flight control data in combination with outdoor flight parameters, re-photographs the location points in the garden that can represent the garden characteristics, and reconstructs the three-dimensional local model of the location point based on the captured three-dimensional photographic data (the three-dimensional local model simulated and constructed at each flight control point p2 is actually a photograph and construction of the location point p1 with garden characteristics in the garden, except that the drone is used to take the photo at the flight control point p2 here), and uses the three-dimensional local model to reconstruct the model at the location point p1 on the original model, so as to obtain a three-dimensional garden model that is fused and adjusted in combination with outdoor parameters.

[0102] The garden 3D model reconstructed with outdoor parameters can better describe the garden characteristics at each location point with garden characteristics based on the corresponding 3D local model, which is convenient for administrators to obtain the characteristic model of each location point with garden characteristics through the garden 3D model. According to the description of garden characteristics and understanding of the garden morphological changes at each location point p1 in the garden, real-time supervision is carried out.

[0103] The location point p1 may be, for example, a location with key protected trees, a location with high mountain scenery features, or other locations with garden features, which may be specifically set by an administrator.

[0104] As an optional implementation scheme of the present application, optionally, according to the parameters (p2, L2), the flight control route is regenerated and the corresponding flight control command is issued to the UAV, and the garden three-dimensional model is re-photographed and corrected, including:

[0105] The drone follows the flight control route and starts the camera at each flight control point p2 at a vertical height of L2 from the garden below to perform three-dimensional oblique photography of the garden area, and obtains a three-dimensional oblique photography data set Mp of each flight control point p2:

[0106] Mp={Mp1, Mp2, Mp3...},

[0107] Among them, Mp1, Mp2, Mp3.....are the three-dimensional oblique photography data at each flight control point p2;

[0108] The three-dimensional oblique photography dataset Mp is transmitted back to the control center through the 5G communication module on the drone based on 5G base station communication.

[0109] Please refer to the above description of flight control for details.

[0110] As an optional embodiment of the present application, optionally, when performing three-dimensional oblique photography of the garden area, it also includes:

[0111] Use infrared ranging equipment to measure the vertical height distance L2 between the drone and the garden below at each flight control point p2;

[0112] The vertical height distance L2 between the drone and the garden below at each flight control point p2 is transmitted back to the control center through the 5G communication module on the drone based on 5G base station communication;

[0113] The control center monitors in real time and determines whether the vertical height distance L2 between the drone and the garden below at each flight control point p2 satisfies the requirement that the vertical height distance L2 between the drone and the garden below at each flight control point p2 is the same height:

[0114] If not, the corresponding flight control command is issued to correct the flight altitude of the drone at the corresponding flight control point p2;

[0115] If so, give up.

[0116] As an optional implementation scheme of the present application, optionally, when the drone starts to shoot at each flight control point p2 at a vertical height of L2 from the garden below according to the flight control route, and performs three-dimensional oblique photography of the garden area, it also includes:

[0117] The drone stays at each flight control point p2 for a period of time, which is limited to 3 to 20 seconds;

[0118] Perform three-dimensional oblique photography at the second level.

[0119] When reconstructing the 3D local model at each location point p1 with garden features, this solution reduces the flight altitude of the drone at each flight control point to L2 in order to avoid data errors caused by drone photography at different altitudes.

[0120] The drone flies according to the flight control command, flies to each flight control point, and descends to a uniform vertical height L2, and starts photographing at each position point p1 relative to the flight control point at a uniform height. When the drone takes photos at each flight control point, it will stay in place for 3 to 20 seconds according to the flight control command, and take three-dimensional photos at the second level. For example, it starts taking photos after staying for three seconds, and takes photos every second to record the dynamic three-dimensional oblique photography data of the garden location points at different second levels.

[0121] Subsequently, the three-dimensional local model of the corresponding location point can be reconstructed on a second-by-second basis based on the three-dimensional data photographed at that moment. In this way, the changes in the garden model at each location point can be dynamically reflected through the three-dimensional local model at the second level, allowing the administrator to better and more flexibly understand the changes in the garden model at each location point with garden characteristics.

[0122] The method for processing the three-dimensional model data by the backend server is not limited or described in this embodiment.

[0123] As an optional embodiment of the present application, optionally, re-photographing and correcting the garden three-dimensional model includes:

[0124] The control center receives and parses the three-dimensional oblique photography data set Mp, and through a three-dimensional simulation modeling application, simulates and constructs a three-dimensional local model at each flight control point p2 based on the three-dimensional oblique photography data at each flight control point p2 in the three-dimensional oblique photography data set Mp, and saves the three-dimensional local model of each relative flight control point p2 into a database.

[0125] As an optional implementation scheme of the present application, optionally, the three-dimensional local model of each relative flight control point p2 includes several:

[0126] At each flight control point p2, a three-dimensional local model is constructed by simulating the three-dimensional oblique photography data acquired at the second level.

[0127] As an optional embodiment of the present application, optionally, re-photographing and correcting the garden three-dimensional model further includes:

[0128] The administrator inputs the photography time of each flight control point p2;

[0129] Dispatching the three-dimensional local model of each relative flight control point p2 at the corresponding photography time;

[0130] The three-dimensional local models of each relative flight control point p2 are composited at the corresponding flight control point p2 on the three-dimensional garden model to complete the dynamic correction of the three-dimensional garden model;

[0131] After the correction is completed, the garden three-dimensional model is updated and saved in the database.

[0132] like Figure 4 As shown, after the drone takes three-dimensional photos of various points in the garden at various flight control points, the background reconstructs the three-dimensional local model of the corresponding garden point p1 based on the three-dimensional data of the corresponding point p1, and composites the three-dimensional local models at each point p1 at the corresponding position on the garden three-dimensional model according to the coordinates of the point p1, thereby realizing model correction and replacement.

[0133] Model correction mainly involves replacing and correcting the local model at the original model location point p1, so that the model at each location point p1 with garden characteristics can be dynamically adjusted, so that the administrator can dynamically understand and control the garden characteristics at each location point p1.

[0134] Therefore, this application does not require a lot of manpower and material resources, can be operated remotely, greatly saves hardware and transportation costs, and is more flexible and efficient to use. It can more flexibly use the flight control points with garden characteristics to monitor and correct the garden three-dimensional model, making it easier for administrators to use the garden three-dimensional model to conduct real-time dynamic supervision of the garden characteristics at each flight control point.
