[0002] In the complex system of land and resources management, land surveying and mapping occupies a core position. Whether it is scientifically planning land use, closely monitoring the dynamic changes of land resources, or clarifying land ownership, accurate surveying and mapping data is an indispensable key support. However, the surveying and mapping equipment currently on the market has revealed many insurmountable drawbacks in practical applications, which seriously restricts the improvement of the quality and efficiency of land and resources management.

[0003] Traditional surveying equipment, such as theodolites and levels, has cumbersome operating procedures, placing extremely high demands on the professional skills and operational abilities of surveyors. In large-scale land and resources surveying operations, it not only consumes a significant amount of time and manpower but is also severely limited by terrain and visibility conditions. In mountainous and forested areas with complex terrain, obstructed visibility often hinders surveying work and makes smooth progress difficult. While some advanced surveying technologies, such as satellite remote sensing, can quickly acquire large-scale geographic information, their image resolution is relatively low, failing to meet the stringent requirements of refined land and resources management. Furthermore, the high cost of satellite remote sensing equipment and the substantial financial and technical resources required for data processing place a heavy economic burden on grassroots land and resources management departments. More importantly, existing surveying equipment suffers from serious deficiencies in data integration and sharing.

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.

[0036] The purpose of this invention is to provide a surveying device and method that is easy to operate, highly adaptable, provides accurate data, and integrates data efficiently.

[0037] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0038] refer to Figures 1-3 The surveying device disclosed in this embodiment of the invention includes at least a surveying box 1. The surveying box 1 is equipped with a surveying component 8. The surveying component 8 includes a laser ranging module 82, an image acquisition module, a data processing module 85, a positioning and navigation module 84, and a power supply and communication module 2.

[0039] It should be noted that the image acquisition module includes a high-definition camera 83 and a panoramic camera 831.

[0040] The working principle of this embodiment is as follows: When the surveying box 1 is in actual operation, the laser ranging module 82, the high-definition camera 83, and the panoramic camera 831 are exposed. The laser ranging module 82, the high-definition camera 83, the panoramic camera 831, the positioning and navigation module 84, the data processing module 85, and the power supply and communication module 2 installed inside the surveying box 1 have the following functions:

[0041] The laser ranging module 82 is located on the top of the device and adopts advanced pulsed laser ranging technology, which can measure the distance to the target point at extremely high speed and with extremely high accuracy. The module is equipped with high-precision optical components, which greatly improves the accuracy and stability of the ranging. Its ranging range can reach up to 500 meters, and the accuracy error is strictly controlled within ±10 mm. The laser ranging module 82 is equipped with a rotating gimbal. With the help of the 360-degree rotating gimbal, the laser ranging module 82 can perform all-round scanning of the target area, quickly and comprehensively acquire three-dimensional spatial information, and provide accurate data support for subsequent surveying and mapping work.

[0042] The device is equipped with a high-definition camera 83 and a panoramic camera 831 mounted on the front.

[0043] The positioning and navigation module 84 integrates multiple advanced satellite positioning systems such as GPS and Beidou, which can quickly and accurately determine the geographical location of the device with a positioning accuracy of sub-meter level, fully meeting the stringent requirements of land and resources surveying for position accuracy. This module not only has positioning function, but also supports real-time navigation. Through intelligent algorithms, it plans the optimal path to the target surveying point for surveyors and provides dual navigation guidance in voice and image, which greatly improves the efficiency of surveying work and reduces the difficulty of the work.

[0044] The data processing module 85, serving as the core brain of the entire device, employs a high-performance embedded processor. It is capable of real-time and efficient processing and analysis of data acquired by modules such as laser ranging, image acquisition, and positioning navigation. The module incorporates self-developed professional surveying data processing software with powerful functions, enabling complex operations such as automatic data stitching, 3D modeling, and area and volume calculation.

[0048] Innovative Adaptability to Complex Environments: Equipped with an adjustable tripod and multiple functional modules, the device possesses strong environmental adaptability, enabling it to conduct surveying and mapping work smoothly in mountainous areas, forests, or densely populated urban areas. Meanwhile, the infrared night vision function and all-weather operation of the image acquisition module further broaden the application scenarios of the device.

[0049] Data accuracy is greatly improved: the application of laser ranging module 82 and high-precision positioning and navigation module 84 ensures the high accuracy of surveying and mapping data; the high-definition and panoramic images acquired by the image acquisition module provide strong support for data analysis and verification, further improving the reliability of the data;

[0050] Efficient and convenient data integration: The data processing module 85 supports the output of multiple data formats, has powerful data processing and analysis capabilities, and can seamlessly connect with other land and resources management systems, facilitating data sharing and integration, and effectively improving the coordination and efficiency of land and resources management.

[0051] It should be noted that, in this embodiment, "top" refers to an appendix. Figure 1 The top of the text refers to the side facing the reader, and the terms "up," "down," "left," "right," and "front" are all relative to the text above. Figure 1 The indicated direction is the basis.

[0052] refer to Figures 1-3 In one implementation, the surveying box 1 is equipped with a mounting base 81, which has an 8-shaped structure. The laser ranging module 82 is installed in the upper mounting hole of the 8-shaped structure, the image acquisition module is installed in the lower mounting hole of the 8-shaped structure, the data acquisition module and the positioning and navigation module 84 are respectively installed on the left and right sides of the mounting base 81. One end of the power supply and communication module 2 is connected to the inner wall of the surveying box 1, and the other end is connected to the positioning and navigation module 84. By reasonably allocating the installation positions of each module, the compactness of the device can be improved and the space occupation can be reduced.

[0053] It should be noted that the mounting base 81 is made of plastic.

[0054] refer to Figures 1-3 In one embodiment, the bottom of the surveying box 1 is provided with a tripod fixing plate 5 connected to the tripod. Four sets of connecting columns are evenly installed on the lower surface of the bottom plate 3 of the surveying box 1. The bottom plate 3 is fixedly connected to the mounting platform 4 through the bottom connecting columns. The bottom of the mounting platform 4 is fixedly provided with a tripod fixing plate 5. Multiple sets of screw holes are evenly opened on the tripod fixing plate 5 for installing outdoor tripods. The tripod can flexibly adjust its height and angle to ensure that it can be quickly and stably positioned under any terrain conditions, laying the foundation for the smooth progress of surveying work.

[0055] refer to Figures 1-3 As a preferred method, a positioning plate 31 is provided on the bottom plate 3 of the surveying box 1. The positioning plate 31 has a docking groove 32. A docking strip 33 is snapped into the docking groove 32. The end of the docking strip 33 away from the docking groove 32 is fixedly connected to the bottom of the fixed seat 34. The top of the fixed seat 34 cooperates with the mounting seat 81 to support the mounting seat 81, so as to ensure stable support for the mounting seat 81.

[0056] It should be noted that the docking groove 32 is set in two sets, and the docking groove 32 extends towards the inside of the surveying box 1. The dimensions of the docking groove 32 and the docking strip 33 are compatible. The two sets of docking strips 33 are respectively inserted into the two sets of docking grooves 32. The cross-section of the docking groove 32 and the docking strip 33 is set as an isosceles trapezoid to realize the snap-fit ​​of the docking strip 33. The surveying component 8 is positioned and installed inside the surveying box 1 through the docking groove 32 and the docking strip 33. The docking strip 33 has a through hole, and the bottom of the docking groove 32 has a screw hole. At the same time, the through hole and the screw hole are set opposite to each other. The long bolt passes through the through hole and is screwed into the inside of the screw hole. The docking groove 32 and the docking strip 33 are fixed together by the screw bolt.

[0057] The cross-section of the fixed seat 34 is an isosceles trapezoid, and the mating surface between the fixed seat 34 and the mounting seat 81 is an arc surface that mates with the bottom surface of the mounting seat 81.

[0058] refer to Figures 4-8 In one implementation, the surveying box 1 is provided with a door 6, and an opening and closing mechanism is provided between the surveying box 1 and the door 6 to realize the opening and closing of the door 6. A sealing gasket for sealing the surveying box 1 is provided on the outer circumference of the door 6. By providing a door 6 on the surveying box 1 and providing a sealing gasket on the outer circumference of the door 6, the opening, closing and sealing of the surveying box 1 can be realized.

[0059] refer to Figures 4-8 In one embodiment, a receiving cavity is provided between the positioning disk 31 and the base plate 3. The opening and closing mechanism includes a C-shaped guide groove 70 opened on the base plate 3, a guide post 75 that passes through the C-shaped guide groove 70 and can slide along the C-shaped guide groove 70, and a Z-shaped crank 76 that is set between the positioning disk 31 and the base plate 3, with one end connected to the guide post 75 and the other end connected to the door body 6. The Z-shaped crank 76 can enter and exit the receiving cavity. When it is necessary to open or close the door body 6, the door body 6 can be opened or closed by manually pushing the door body 6 so that the guide post 75 slides in the C-shaped guide groove 70. Since the Z-shaped crank 76 is set with a Z-shaped structure, when the door body 6 is in the fully open state, it can fit against the side wall of the surveying box 1 to ensure the compactness of the device.

[0060] It should be noted that the C-shaped guide groove 70 and the guide post 75 are matched in size. The guide post 75 is inserted inside the C-shaped guide groove 70. After the guide post 75 passes through the C-shaped guide groove 70, a limiting piece 77 is fixedly installed at the bottom. The limiting piece 77 is circular and its diameter is larger than the width of the guide groove to prevent the guide post 75 from coming out of the C-shaped guide groove 70.

[0061] A support leg is provided between the positioning plate 31 and the base plate 3 to form a receiving cavity.

[0062] refer to Figures 4-8As a preferred method, the end of the C-shaped guide groove 70 extending into the box body is connected to a sealing interference groove 701. The direction of the sealing interference groove 701 is perpendicular to the plane where the door 6 is located after it is closed. By setting the sealing interference groove 701, when the door 6 is closed, the door 6 can move into the surveying box 1 through the guidance of the sealing interference groove 701, so that the sealing gasket set around the door 6 fits into the surveying box 1, thereby achieving the sealing of the surveying box 1.

[0063] It should be noted that the Z-shaped crank 76 is made of plastic.

[0064] refer to Figures 4-8 As a preferred embodiment, the system also includes a drive mechanism 7 for opening and closing the door 6. The drive mechanism 7 includes a mating seat 74 disposed on a Z-shaped crank 76 at the end that mates with the C-shaped guide groove 70. The mating seat 74 has a connecting groove 741, which is a dovetail groove opening away from the end of the Z-shaped crank 76. A transmission plate 71 is disposed at the open end of the connecting groove 741. The rotation of the transmission plate 71 is used to move the guide post 75 to slide within the C-shaped guide groove 70. The end of the transmission plate 71 away from the connecting groove 741 is provided with a feature that allows the transmission plate 71 to rotate. The rotating shaft 72 has a drive rotation assembly 78 at the end away from the transmission plate 71, which enables the rotating shaft 72 to rotate. The rotating shaft 72 is fixedly connected to the drive rotation assembly 78 through the base plate 3 via a bearing. The rotation arc of the transmission plate 71 is consistent with the arc of the C-shaped guide groove 70. When the door 6 needs to be opened or closed, the rotating shaft 72 is driven to rotate by the drive rotation assembly 78, which in turn drives the transmission plate 71 to rotate, thereby actuating the guide post 75 and making the guide post 75 slide in the C-shaped guide groove 70 to complete the opening and closing of the door 6.

[0065] refer to Figures 4-8 As one implementation method, the rotary drive component is a knob or a drive motor.

[0066] refer to Figures 4-8 As one implementation method, the connecting piece and the connecting groove 741 are provided with a circular mating piece 73 that mates with the connecting groove 741. The circular mating piece 73 facilitates the guidance of the connecting groove 741.

[0067] The usage process in this embodiment is as follows:

[0068] When the device is no longer used outdoors, the door 6 at the front of the surveying box 1 closes by rotating the drive rotating assembly 78, causing the rotating shaft 72 connected to the drive rotating assembly 78 to drive the transmission plate 71 to rotate. At this time, the transmission plate 71 drives the Z-shaped crank 76 to deflect through the docking seat 74. The guide post 75 at the bottom of the Z-shaped crank 76 is slidably disposed inside the C-shaped guide groove 70. The door 6, which is fixedly connected to the end of the Z-shaped crank 76, moves towards the side closer to the opening of the surveying box 1 until the guide post 75 moves to the connection position between the C-shaped guide groove 70 and the sealing interference groove 701. At this time, the door 6 and the surveying box... With the openings facing each other, and the sealing interference groove 701 perpendicular to the plane where the door 6 is closed, the door 6 can move vertically in the direction of its extension into the surveying box 1 until the guide post 75 moves to the end of the sealing interference groove 701. At this point, the sealing gasket on the outer circumferential direction of the door 6 is just engaged inside the opening of the surveying box 1, providing tight windproof, dustproof, and rainproof protection for the interior of the surveying box 1. The door 6 is driven by a Z-shaped crank 76, replacing the traditional hinged installation method. The Z-shaped crank 76 rotates the door 6 around the rotation center of the pivot 72. When opened, the door 6 rotates outwards, unlike hinged doors. The design leaves a relatively large space on one side of the door 6 for the door's opening and closing swing, making it particularly suitable for the compact installation environment of the surveying box 1, effectively saving installation space. The Z-shaped crank 76 rotating door 6 achieves a tighter fit when closed through the Z-shaped crank 76, guide post 75, C-shaped guide groove 70, and sealing interference groove 701 mechanism, allowing for a smaller gap between the door 6 and the surveying box 1. In contrast, hinged doors may have slightly poorer sealing performance between the door 6 and the surveying box 1 due to the hinge's structural characteristics. Better sealing performance helps protect the surveying components 8 inside the surveying box 1 from external dust, moisture, rain, and snow when the door is not in use outdoors. To prevent contamination and enhance protection levels, the surveying component 8 operates in a favorable environment. The opening and closing of the Z-shaped crank 76 rotating door 6 can be easily achieved through a well-designed Z-shaped crank 76 with appropriate length and rotation angle. The installation method of the Z-shaped crank 76 rotating door 6 is simpler and smoother in appearance, without the obvious exposed structure of hinges, making the surveying box 1 look neater and more aesthetically pleasing. For some application scenarios with high requirements for appearance, such as the surveying equipment surveying box 1 in urban public environments or exhibition venues, the Z-shaped crank 76 rotating door 6 can better integrate into the surrounding environment and enhance the overall visual effect.

[0069] The present invention also discloses a surveying method using the surveying apparatus described above, comprising the following steps:

[0070] Step A: Before heading to the surveying site, surveyors must carefully check whether the device has sufficient power and whether each functional module is working properly. The device should be mounted on a tripod, and the height and angle of the device should be flexibly adjusted according to the actual terrain. The device power should be turned on, and the system should be allowed to start and complete its self-test to ensure that the device is in the best working condition.

[0071] Step B: Obtain the current location information through the positioning and navigation module 84, and input the coordinates of the target surveying point into the system. The system will use intelligent algorithms to automatically plan the optimal path to the target point, and guide the surveyors in the direction of progress through voice and image prompts, ensuring that the surveyors can reach the target surveying point quickly and accurately.

[0072] Step C: After arriving at the target survey point, activate the laser ranging module 82 and the image acquisition module. The image acquisition module includes a panoramic camera 831 and a high-definition camera 83. The surveyor uses the gimbal on the tripod to perform a full-range scan of the target area to acquire distance data and image information. During the acquisition process, the parameters of laser ranging and image acquisition can be flexibly adjusted according to actual needs to ensure that the acquired data is accurate and comprehensive.

[0073] Step D: After data collection is completed, the data processing module 85 will process and analyze the collected data in real time. Using professional data processing software, it will automatically stitch together laser ranging data and image data to generate a three-dimensional model of the target area and calculate relevant parameters such as area and volume, providing intuitive and accurate data support for subsequent land and resources management work.

[0074] Step E: Through power supply and communication module 2, the processed surveying data is uploaded to the server of the land and resources management department in real time; at the same time, surveyors can also save the data to local storage devices for later review and analysis; in addition, surveyors can also operate the device through the remote control function to realize remote data acquisition and processing.
