DETAILED DESCRIPTION OF THE EMBODIMENTS

[0026] With the rapid development of technology and the continuous growth of engineering surveying and mapping requirements, the application of unmanned aerial vehicle (UAV) remote sensing devices in surveying and mapping engineering is becoming increasingly widespread. This device combines advanced computer technology, GPS navigation systems, information technology, and data processing systems, providing efficient, accurate, and real-time data acquisition and processing capabilities for surveying and mapping engineering.

[0027] UAV flight platform: The UAV flight platform is the foundation of the remote sensing device, carrying key equipment such as remote sensing sensors and control systems. According to mission requirements, UAV flight platforms can be divided into two major categories: fixed-wing and rotary-wing. Fixed-wing UAVs have the advantages of long endurance, high flight speed, and suitability for large-area operations. However, their operation is relatively complex, they have high requirements for the site during takeoff and landing, and the risk factor is relatively large. The fuselage of fixed-wing UAVs is usually made of high-strength and low-quality materials such as expanded polypropylene plastic (EPP), expanded polystyrene polyethylene mixture (EPO), fiberglass, wood, etc., to ensure flight stability and safety. The power device of fixed-wing UAVs usually includes an aviation engine and a thrust propeller to provide sufficient thrust to maintain flight. In addition, the flight control system is the core part of fixed-wing UAVs, consisting of a flight control board, inertial navigation system (IMU), air pressure and airspeed sensors, GPS receivers, etc. These devices work together to achieve precise control of the aircraft's attitude, altitude, speed, and heading, ensuring that the UAV can fly along the planned route. Rotary-wing UAVs are widely used for their simple operation process, no need for a specific site to take off, vertical takeoff and landing, and high safety. However, their flight time is relatively short, and the efficiency is low, making them suitable for surveying tasks in small areas or complex terrains. The fuselage of rotary-wing UAVs is usually made of carbon fiber materials to reduce weight and improve flight performance. The power device of rotary-wing UAVs is usually provided by lithium batteries. Although the storage capacity of lithium batteries is limited, it is sufficient to support the short-time flight of rotary-wing UAVs. The flight control system also consists of a flight control board, IMU, air pressure and airspeed sensors, GPS receivers, etc., to achieve precise control of the flight trajectory. In addition, rotary-wing UAVs are also equipped with a remote controller, enabling operators to remotely control their flight direction and altitude.

[0028] Remote Sensing Sensors: Remote sensing sensors are the core components of UAV remote sensing devices, used to collect required data such as images and videos of the target area. According to the needs of mapping tasks, remote sensing sensors can be divided into various types, such as high-resolution digital cameras, optical film cameras, imaging spectrometers, etc. High-resolution digital cameras are one of the commonly used remote sensing sensors in surveying and mapping projects. It has characteristics such as high resolution, high sensitivity, and high dynamic range, and can capture the fine texture and detailed features of the target area. The lens of the digital camera is usually made of high-quality optical glass to ensure the clarity and accuracy of the image. In addition, the digital camera is also equipped with an image processor and a storage device for preliminary processing and storage of the collected images. Although with the popularization of digital technology, the application of optical film cameras in surveying and mapping projects has gradually decreased, but in some specific cases, it still has certain advantages. Optical film cameras capture images through film, with relatively high image quality and stability. However, its processing process is relatively cumbersome, requiring film developing and printing, and the cost is relatively high. Imaging spectrometers are remote sensing sensors that can simultaneously obtain the spatial information and spectral information of the target area. It uses spectral analysis technology to perform multi-band imaging on the target area, thereby obtaining spectral characteristics in different bands. Imaging spectrometers have wide application value in fields such as geological exploration and environmental monitoring.

[0029] Control System: The control system is an important part of the UAV remote sensing device, responsible for tasks such as controlling the flight trajectory of the UAV, data acquisition of remote sensing sensors, and data transmission. The control system usually consists of a flight control system, a mission equipment control computer, a radio telemetry and remote control system, etc. The flight control system is the core part of the UAV, responsible for realizing the flight control and mission equipment management of the UAV. It consists of sensors, actuators, and a flight control computer, etc. The sensors are used to monitor the attitude, altitude, speed, heading, etc. of the UAV in real time; the actuators adjust the flight attitude and altitude of the UAV according to the instructions of the flight control computer; the flight control computer calculates the flight trajectory of the UAV based on the information feedback by the sensors and the preset flight route, and issues corresponding instructions to the actuators. The mission equipment control computer is used to control the data acquisition and processing of remote sensing sensors. It automatically calculates and controls the exposure interval of the camera and the drift angle correction of the stable platform according to data such as the position, ground speed, altitude, heading, attitude angle of the UAV, as well as the set aerial photography scale and overlap degree. The mission equipment control computer has two control modes: program control and remote control, enabling the operator to flexibly adjust the parameters of data acquisition as needed. The radio telemetry and remote control system is used to transmit the status parameters of the UAV and remote sensing equipment as well as the instructions of ground operators. It includes two parts: a radio telemetry system and a radio remote control system. The radio telemetry system is used to measure and display the attitude, altitude, speed, heading, etc. of the UAV in real time for ground personnel to master the flight status of the UAV. The radio remote control system is used to transmit the instructions of ground operators to guide the UAV to fly according to the will of ground personnel. The data transmission device is responsible for transmitting the data collected by the remote sensing sensors to the ground control station or data processing center in real time. The data transmission device usually consists of a wireless communication module, a data storage device, and a data processing module, etc. The wireless communication module is the key device for realizing data transmission between the UAV and the ground control station. It uses advanced wireless communication technologies such as Wi-Fi, 4G / 5G, etc. to achieve high-speed and stable data transmission. The wireless communication module has strong anti-interference ability and data transmission ability, and can maintain a stable communication connection in complex environments. The data storage device is used to store the original data collected by the remote sensing sensors. It usually uses high-performance solid-state drives or mechanical hard drives, with a large storage capacity and high read and write speeds. The data storage device is also equipped with data backup and recovery functions to ensure the security and reliability of the data. The data processing module is responsible for the preliminary processing and analysis of the collected data. It uses advanced data processing algorithms and technologies to perform denoising, calibration, enhancement, etc. on the original data to improve the quality and usability of the data. The data processing module can also further analyze and process the processed data according to the requirements of the mapping task, such as generating a digital orthophoto map (DOM), a digital elevation model (DEM), etc.

[0030] Ground Control Station: The ground control station is an important part of the UAV remote sensing device, which is used for tasks such as real-time monitoring of the UAV's flight status, controlling the UAV's flight trajectory, receiving and processing data collected by remote sensing sensors, etc. The ground control station usually consists of three parts: a display system, a control system, and a data transmission system. The display system is used to display the UAV's flight status in real time, including information such as attitude, altitude, speed, and heading. The display system usually adopts a high-resolution display screen and an intuitive operation interface, enabling the operator to clearly understand the UAV's flight status. The control system is used to control the UAV's flight trajectory and the data collection of remote sensing sensors. The operator can input flight instructions and data collection parameters through the control system to achieve remote control of the UAV and management of data collection tasks. The control system also has an automatic fault diagnosis and display function. Once the remote control fails or other faults occur, it can automatically take emergency measures to ensure the safety of the UAV. The data transmission system is used to transmit the instructions and data of the ground control station to the UAV and transmit the data collected by the UAV back to the ground control station in real time. The data transmission system usually adopts high-speed and stable communication technologies, such as optical fiber communication, satellite communication, etc., to ensure the real-time and accuracy of data.

[0031] Workflow of UAV Remote Sensing Device: The workflow of the UAV remote sensing device usually includes three stages: flight preparation, flight execution, and data post-processing. In the flight preparation stage, the operator needs to assemble and debug the UAV to ensure that its various performance indicators are normal. At the same time, it is also necessary to plan the flight route, set data collection parameters, and check the equipment and network connection of the ground control station. In addition, a pre-flight safety check of the UAV is required to ensure that it can take off and perform tasks safely. In the flight execution stage, the operator sends flight instructions and data collection instructions to the UAV through the ground control station. The UAV automatically flies according to the planned route, and at the same time, the remote sensing sensor starts to collect the required data such as images and videos of the target area. During the flight, the operator can monitor the UAV's flight status and data collection situation in real time through the ground control station and make adjustments and optimizations as needed. In the data post-processing stage, the operator needs to process and analyze the collected data. First, it is necessary to perform processing such as denoising, calibration, and enhancement on the original data to improve the quality and usability of the data. Then, according to the requirements of the mapping task, further analysis and processing are carried out on the processed data, such as generating a digital orthophoto map (DOM), a digital elevation model (DEM), etc. Finally, the processed data is stored in a specified location for subsequent use and analysis.

In addition, technologies such as cloud computing and big data can be used to realize real-time data transmission and processing, further improving operation efficiency. As the requirements for accuracy in surveying and mapping engineering continue to increase, future UAV remote sensing devices will place more emphasis on breakthroughs in precise measurement technologies. By introducing higher-precision remote sensing sensors and optimizing data processing algorithms, more accurate and detailed measurements of the target area can be achieved. This will help improve the accuracy and reliability of surveying and mapping engineering and provide more accurate data support for the development of related fields. Future UAV remote sensing devices will place more emphasis on the integration of multi-source data and the expansion of application areas. By integrating data resources from different sources and of different types, data complementarity and enhancement can be achieved, improving the comprehensive application value of the data. At the same time, UAV remote sensing technology can also be combined with other advanced technologies, such as geographic information system (GIS) and global positioning system (GPS), to expand its application fields and scope and provide strong support for the development of more fields.
