Description

Technical Field

[0001] This invention belongs to the field of traditional settlement landscape surveying technology, and in particular relates to a surveying method and system for the spatial area of ​​water system landscape in traditional Huizhou settlements. Background Technology

[0002] Hui-style traditional settlements are among the most typical existing traditional settlements in my country. Within these settlements, water features are integrated into all other traditional landscape elements. Furthermore, the water features significantly influence the overall appearance of these other landscape elements.

[0003] As part of traditional settlement spaces, water system landscape spaces exhibit their unique cultural and humanistic characteristics through their own geographical and historical environment and cultural traditions. Studying the features of water system landscapes within traditional settlement areas is of great significance for studying the features of other landscapes within traditional settlement areas.

[0004] Due to the diversity and complexity of various landscape features within traditional Huizhou settlements, the water system landscape spaces within these settlements are also quite diverse. Systematically organizing and planning the water system landscape within these traditional settlement areas in a high-definition manner has become a problem that needs to be solved. Summary of the Invention

[0005] The purpose of this invention is to provide a method and system for surveying the water system landscape of traditional Huizhou settlements. This involves establishing a signal base station and linking it with a drone signal. The entire spatial area is then divided into zones according to its characteristics, and a surveying route is designed. Marker points are evenly placed along the surveying route, and water system depth information is collected at these points. Water system depth information markers and signal transmission devices are then installed, allowing the drone to collect terrain images and receive water system depth information along the surveying route. Finally, the collected terrain images and water system depth information are used to create 3D models of independent areas, which are then stitched together to complete the 3D modeling of the water system landscape within the entire traditional settlement area. This solves the existing problem of systematically and accurately organizing and planning the water system landscape within traditional settlement areas.

[0006] To solve the above-mentioned technical problems, the present invention is achieved through the following technical solution: This invention provides a method for surveying the water system landscape space area of ​​traditional Huizhou settlements, comprising the following steps: S1: Establishing a ground reference signal station, connecting the UAV's onboard positioning system to the ground reference signal station, and calibrating the coordinate position; S2: Dividing the boundaries of different water system areas, and designing multiple sets of different surveying routes according to the water system landscape space area boundaries of different traditional settlements, and inputting the designed surveying routes into the UAV; S3: Setting several marker points along the designed multiple sets of surveying routes, pre-measuring the water system depth at the marker points, and fixing a water system depth marker pole at each marker point, and fixing an information transmission device on the top of the water system depth marker pole to transmit the measured water system depth information to the UAV's onboard signal receiving device; S4: Flying the UAV according to the designed surveying routes in the water system landscape space area of ​​different traditional settlements, and during the flight, when the UAV is above each marker point, performing a survey of the water system landform pattern at that location. S5: During the surveying process, the drone simultaneously receives water system depth information while flying along a surveying route and saves the water system depth information emitted by each marker point; S6: After a single survey is completed, the captured images are matched with the water system depth information and transmitted to the ground signal base station for storage and archiving; S7: The drone completes the next set of surveying routes for the water system landscape space area of ​​the same traditional settlement, collecting the next set of information until all surveying routes for the water system landscape space area of ​​the same traditional settlement are completed, and the water system landscape space area information of all traditional settlements is collected in this way; S8: Based on the collected image information of the water system landscape space area of ​​the same traditional settlement and the matching water system depth information, a three-dimensional model of the water system geomorphology of a single independent water system landscape space area is created, and the three-dimensional models of different areas are stitched together. Finally, the three-dimensional geomorphological models of multiple independent water system landscape space areas are stitched together to form a three-dimensional map of the water system landscape space geomorphology of the entire traditional settlement.

[0007] As a preferred technical solution of the present invention, the water system landscape space area of ​​the traditional settlement in S2 includes the water system landscape of the traditional settlement courtyard, the water system landscape of the traditional settlement street and alley, and the natural water system landscape other than the water system landscape of the traditional settlement.

[0008] As a preferred technical solution of the present invention, the traditional settlement courtyard water system landscape includes private wells in the courtyard, as well as water systems where streams outside the houses are introduced into the courtyard; the traditional settlement street and alley water system landscape includes street and alley water systems and pond water systems within the traditional community; the natural water system landscape other than the traditional settlement water system landscape includes farmland water systems and natural river systems.

[0009] As a preferred embodiment of the present invention, the individual surveying routes in S2 are set with different flight altitudes.

[0010] As a preferred embodiment of the present invention, the UAV mapping route in S2 is set in 2-3 groups.

[0011] As a preferred embodiment of the present invention, the water system depth information markers in S3 are uniformly set along the surveying route.

[0012] A mapping system for the water system landscape space area of ​​traditional Huizhou settlements includes the following modules: a data collection module, which collects images taken by drones and water system depth information received by drones from the information transmission device at the top of the depth marker pole, and archives the collected images and water system depth information according to the mapping route; and a data processing module, which uses the archived images and water system depth information to draw a three-dimensional model of the water system landscape space area of ​​a traditional settlement to which a single marker point belongs, according to the mapping route, and compares and stitches together the three-dimensional models of the water system landscape space areas of traditional settlements of the same type to obtain a three-dimensional model map of the water system landform of a single independent water system landscape space area.

[0013] As a preferred technical solution of the present invention, it also includes a correction output module, which is used to correct the three-dimensional geomorphological models of multiple independent water system landscape spatial areas along the regional boundaries and stitch them together into a three-dimensional geomorphological model of the water system landscape space of the entire traditional settlement and output it.

[0014] The present invention has the following beneficial effects: This invention establishes a base station to connect drones, and plans reasonable surveying routes for different water system landscape areas according to their characteristics. Water system depth markers are pre-set evenly along each surveying route to collect water system depth information. A depth information marker pole is also set at each marker point to transmit the water system depth information to the drone. The drone collects surveying information and water system depth information. The collected information is then processed by a data processing module to complete a 3D model of the water system landscape within the entire traditional settlement area. In designing the surveying routes, the characteristics of different water system landscape areas were taken into account, and the drone's flight altitude was designed to allow the drone to clearly capture and collect the desired information. Furthermore, by combining image information and water system depth information, the model's proportions are maintained, improving the reliability of the established 3D model.

[0015] Of course, any product implementing this invention does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

Obviously, the drawings described below are only some embodiments of the present invention. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort.

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. Example

[0019] Please see Figs. 1-3 As shown, this invention provides a method for surveying and mapping the water system landscape area of ​​traditional Huizhou settlements, comprising the following steps: S1: Establish a ground reference signal station as a static reference point for the UAV, and connect the UAV's onboard positioning system to the ground reference signal station. Using the ground reference signal station as a fixed spatial coordinate system, the position signal of the UAV can be measured more accurately. The ground reference signal station can be constructed using global navigation satellite systems such as GNSS.

[0020] S2: Divide the boundaries of different water system areas, and design multiple sets of different surveying routes according to the water system landscape space boundaries of different traditional settlements. Set 2-3 sets of UAV surveying routes to obtain more accurate surveying data. Each surveying route has a different flight altitude according to the water system landscape space of different traditional settlements, and input the designed surveying routes into the UAV.

[0021] The water system landscape area of ​​traditional settlements includes the water system landscape of traditional settlement courtyards, the water system landscape of traditional settlement streets and alleys, and the natural water system landscape other than the water system landscape of traditional settlements.

[0022] Traditional settlement courtyard water features include private wells within the courtyard, as well as water systems where streams flow into the courtyard from outside the house.

[0023] The water system landscape of traditional settlements includes street and alley water systems (such as public wells) as well as pond water systems within the traditional community (such as the main rivers and canals on both sides of the main road).

[0024] Natural water system landscapes, in addition to traditional settlement water system landscapes, include farmland water systems (paddy fields) and natural river systems (water depressions and ponds formed by the terrain).

[0025] S3: Set up several marker points evenly along the designed multiple sets of surveying routes. The specific number of marker points is defined according to the corresponding water system area. Measure the water system depth at each marker point in advance, and fix a water system depth marker pole at each marker point. Fix an information transmission device on the top of the water system depth marker pole to transmit the measured water system depth information to the UAV's onboard signal receiving device. When the UAV subsequently performs surveying work along the surveying route, it can accurately receive the water system depth information at the corresponding water system depth marker pole.

[0026] S4: Fly the drone along the designed mapping route in the water system landscape space area of ​​different traditional settlements, and take pictures of the water system landform pattern when the drone is above each marker point during the flight.

[0027] When the drone is filming along the courtyard water system, the planned flight altitude should be appropriately lowered when encountering a private well in the courtyard so that the drone can clearly film the state of the well. When encountering a stream outside the house that flows into the courtyard, the planned flight altitude should be appropriately increased, and the planned surveying route should include the main stream so that the drone can fully include the stream outside the house into the courtyard within the filming range.

[0028] When using drones to photograph ponds and waterways within traditional communities, the first step should be to plan a surveying route along the boundaries of the main rivers and canals on both sides of the main road. This surveying route should be able to clearly capture the details of the boundary waterways, and the flight altitude should be lowered. Then, a surveying route should be planned to map the overall flow direction of the main rivers and canals on both sides of the main road. This surveying route should be able to clearly capture the overall flow direction of the main rivers and canals on both sides of the main road, and the flight altitude should be increased.

[0029] When using drones to photograph farmland water systems, the surveying route should be planned according to the different gradients of the paddy fields, and a local-to-global approach should be adopted. When taking pictures, the natural landscape around the paddy fields should be included, and the drone's flight altitude should be lowered. When taking pictures of the overall landscape, the drone's flight altitude should be raised.

[0030] While flying along a surveying route, the drone simultaneously receives water system depth information and saves the water system depth information transmitted by each marker point. This provides corresponding water system depth information for subsequent modeling, preventing modeling scale imbalance. After a single surveying flight is completed, the water system depth information transmitted by the marker points evenly set along the route is combined with the captured images to support subsequent data matching and 3D modeling processes.

[0031] S5: After a single survey is completed, the captured images are matched with the altitude data information and transmitted to the ground signal base station for storage and archiving.

[0032] S6: Enable the UAV to complete the next set of surveying routes for the water system landscape space area of ​​the same traditional settlement, collect the next set of information until all surveying routes for the water system landscape space area of ​​the same traditional settlement are completed, and complete the collection of information on the water system landscape space area of ​​all traditional settlements in this way, thus completing all data collection work.

[0033] S7: Based on the collected image information of the water system landscape space area of ​​the same traditional settlement and the matching water system depth information, create a three-dimensional model of the water system landform of a single independent water system landscape space area, correct and stitch the boundaries of the three-dimensional models of different areas, and finally stitch the three-dimensional models of the landform of multiple independent water system landscape space areas into a three-dimensional model of the water system landscape space of the entire traditional settlement.

[0034] In the specific implementation process, a GNSS signal base station is first established, and coordinates are established using the signal base station as the base point. The UAV's onboard system is then linked to the signal base station. The survey area is divided according to the boundaries of different water system regions. Two to three matching survey routes are designed for the characteristics of different water system regions, and water system depth markers are evenly set on the survey routes according to the characteristics of different water system regions. The water system depth at each water system depth marker is measured, and water system depth marker poles are fixedly set at the water system depth markers. A signal transmitting device is set on the top of the water system depth marker poles. The UAV is launched and flies multiple times to complete all survey routes. During the survey, water system depth information at each water system depth marker is collected, and topographic images of the corresponding water system regions are obtained and stored. By combining the captured images and the collected water system depth information, the scale of the captured topographic images can be confirmed, and a 3D model of the corresponding water system region can be created. By cropping and adjusting the scale of the boundary areas of all the 3D models of the water system regions and splicing them together, a complete 3D map of the water system landscape space of the traditional settlement can be created, thus completing the entire survey process. Example

[0035] Please see Fig. 3 As shown. This invention is a mapping system for the water system landscape space of traditional Huizhou settlements, comprising the following modules: The data collection module is used to collect images taken by the UAV and water system depth information received by the UAV from the information transmitting device at the top of the depth marker pole, and to archive the collected images and water system depth information according to the survey route.

[0036] The data processing module is used to draw archived images and water system depth information into a three-dimensional model of the water system landscape space area of ​​a traditional settlement to which a single marker point belongs, according to the surveying route. The three-dimensional models of the water system landscape space area of ​​the same type of traditional settlement are compared and stitched together to obtain a three-dimensional model map of the water system landform of a single independent water system landscape space area.

[0037] The correction output module is used to correct the 3D geomorphological models of multiple independent water system landscape areas along the regional boundaries and stitch them together into a 3D geomorphological model of the water system landscape of a traditional settlement and output it.
