[0024] Figure 1 This is a system diagram of a boundary survey and marking application system based on RTK UAV laser radar of the present invention. DETAILED DESCRIPTION

[0025] like Figure 1 As shown, a boundary survey and marking application system based on RTK UAV laser radar includes:

[0026] RTK UAV Platform

[0027] This is the aerial carrier of the entire system, used to carry the LiDAR equipment and perform high-precision positioning. It is equipped with a high-precision GNSS receiver that can achieve real-time dynamic positioning at the centimeter or millimeter level, providing a guarantee for the precise position determination of the drone during flight; it is also equipped with an inertial navigation system, which assists the attitude control and position update of the drone during flight. Even in complex airflow environments or when the signal is temporarily blocked, it can ensure the stable flight of the drone, maintain positioning accuracy, and ensure the accuracy of LiDAR mapping.

[0028] LiDAR Mapping Module

[0029] Installed on the RTK UAV platform, it is a key part for obtaining spatial information of surface targets. It mainly includes a laser scanner, which emits laser pulses and receives reflected signals; a signal processor, which is responsible for processing the received reflected signals and calculating the distance and angle information through a series of complex algorithms; and a point cloud generator, which generates three-dimensional point cloud data of surface targets based on the distance and angle information obtained by the signal processor. These data lay the foundation for the subsequent generation of high-precision maps.

[0030] Data processing module

[0031] It is used to receive, process and analyze the data collected by the LiDAR mapping module. It has a data preprocessing unit inside, which first performs preprocessing operations such as filtering and denoising on the collected raw data to remove invalid data caused by environmental interference, equipment errors and other factors, and improve data quality; the map generation unit uses professional map construction algorithms to generate high-precision maps based on the preprocessed data, clearly presenting the topography of the survey area; the boundary marker position calculation unit combines map information and pre-set boundary survey requirements to calculate the precise position of the boundary marker through an accurate mathematical model, providing key coordinate basis for boundary survey and marker establishment.

[0032] Boundary Survey and Marking Module

[0033] According to the information generated by the data processing module, the boundary markers are automatically or semi-automatically set at the specified location. The boundary marker selector selects the most suitable boundary marker from the preset multiple boundary marker types based on the precise location information provided by the boundary marker location calculation unit, combined with the surrounding environment, boundary marker specifications and other factors; the boundary marker installation device installs the selected boundary marker at the specified location after receiving the boundary marker selection instruction, ensuring that the boundary marker is firmly established and completing the boundary survey and marking task.

[0034] User interface module

[0035] This module is an interactive window between the operator and the entire system. It is used to display the progress of boundary survey and landmark setting, so that the operator can understand the progress of the work in real time; display the results, including the generated high-precision map, the location of the established boundary markers and other information, so as to facilitate the intuitive evaluation of the work results; and can also display detailed map information to assist the operator in further analysis. At the same time, it provides a wealth of user interaction functions. The operator can input boundary survey requirements, adjust system parameters, control the flight path of the drone, etc. through this interface to achieve human-machine collaborative operation.

[0036] System workflow

[0037] First, the operator sets the boundary survey task parameters through the user interface module, starts the RTK UAV platform, takes off with the LiDAR mapping module, and flies according to the predetermined route. During the flight, the LiDAR mapping module continuously emits laser pulses and receives reflected signals, generates three-dimensional point cloud data and transmits it to the data processing module in real time. The data processing module pre-processes the received data, generates maps, and calculates the position of boundary markers, and transmits the calculation results to the boundary survey and marking module. Based on the information received, the boundary survey and marking module selects appropriate boundary markers and marks them at the designated location through the boundary marker installation device. During the whole process, the user interface module displays the work progress and results in real time, and the operator can intervene and adjust at any time according to the situation.

[0039] High precision: With the high-precision positioning of the RTK UAV platform and the precise mapping of the LiDAR, the high-precision requirements of boundary surveying and marking are achieved, greatly improving the accuracy compared to traditional methods.
