Description
Technical Field
[0001] The present invention relates to the technical field of remote sensing imaging UAVs, and more particularly to a remote sensing imaging UAV for three-dimensional map production. Background Art
[0002] Remote sensing drones for 3D mapping are high-tech devices that combine advanced aviation technology with precise remote sensing and mapping capabilities. They feature a lightweight, durable, and aerodynamic airframe, equipped with a high-precision flight control system. Integrating multiple positioning and navigation technologies, such as GPS and differential GPS, they achieve centimeter-level positioning and fly precisely along pre-set routes. Their image acquisition module, equipped with a high-resolution digital camera, multispectral camera, or infrared camera, allows flexible adjustment of capture parameters to meet specific needs, ensuring an optimal overlap between adjacent images. The data transmission and storage module utilizes wireless and high-capacity storage media to ensure real-time data transmission and complete storage. From mission planning to flight mapping and data processing, they can efficiently generate detailed 3D map models for a variety of fields, including urban planning, topographic mapping, and agricultural and forestry monitoring. They are a key force driving changes in the acquisition and application of geographic information.
[0003] In related technologies, existing remote sensing drones typically have built-in attitude adjustment functions. When encountering strong winds, they adaptively adjust the rotational speed of the corresponding rotor to stabilize the drone's attitude, allowing for stable flight. However, when drones collect image data in relatively open scenes such as the sea or the surface of large lakes, vast grasslands, and desert areas, these scenes lack terrain or buildings and are windy areas where wind flows more freely and strongly. In strong crosswinds, even if the rotors generate restoring torque by changing their rotational speed and angle, the drone may still experience significant attitude deviations due to the strong wind. Relying solely on rotor adjustment may not be able to completely offset the impact of wind on the drone's attitude. Summary of the Invention

[0018] The subject matter described herein will now be discussed with reference to exemplary embodiments. It should be understood that these embodiments are discussed solely to enable those skilled in the art to better understand and implement the subject matter described herein, and that the functions and arrangements of the elements discussed may be varied without departing from the scope of this specification. Various examples may omit, substitute, or add various processes or components as needed. In addition, features described with respect to some examples may also be combined in other examples.
[0019] Please refer to Figures 1 to 2 In an embodiment of the present invention, a remote sensing imaging drone for three-dimensional map production is provided, comprising: a drone body 1, an image acquisition module, a wind direction measurement module, a center of gravity adjustment mechanism, a wind force measurement module, a posture adjustment module, and a control module; Among them, the drone body 1 has the appearance design of a conventional drone, and is also equipped with relevant functional components such as a positioning module, an information storage module, and a power module. Since they belong to the existing technology, they will not be described here in detail.
[0020] The image acquisition module, mounted on one side of the drone body 1, is used to photograph the target area and acquire the required image data. This module can be a high-resolution camera, a multispectral camera, or an infrared camera, typically located at the bottom of the drone body 1. It can be used to acquire image information in different wavelength bands to meet specialized surveying and mapping needs, such as vegetation analysis and thermal imaging. Furthermore, the image acquisition module's data storage and transmission capabilities allow it to store captured image data. High-capacity storage media (such as memory cards) are typically used to store large numbers of image files. Furthermore, the module also features data transmission capabilities, allowing it to transmit image data in real time back to the ground control station via wireless communication (such as Wi-Fi, 4G / 5G, etc.), allowing operators to promptly review image quality and conduct preliminary analysis. After the mission is complete, the stored data can also be fully exported for subsequent processing.
[0021] The wind direction measurement module is set on the top of the drone body 1 and is used to obtain real-time wind direction data of the current position of the drone body 1. The wind direction measurement module is a wind direction sensor. The wind direction sensor is installed on the top of the drone body 1. The wind direction sensor is electrically connected to the control module. Specifically, the types of wind direction sensors that can be used include mechanical wind vane sensors, ultrasonic wind direction sensors, etc.
[0022] The wind force measurement module is arranged on the outside of the drone body 1 and is used to obtain the wind force data of the current position of the drone body 1; specifically, the wind force measurement module includes at least four wind sensors, and the four wind sensors are respectively installed on the front, back, left and right sides of the drone body 1. The wind sensors are electrically connected to the control module, and the specific types of the sensors can be three-cup wind speed sensors, hot wire wind speed sensors, etc.
[0023] The attitude adjustment module is installed in the main body of the drone, which is used to stabilize the flight attitude of the drone and assist in judging the attitude changes caused by changes in the center of gravity. Specifically, the inertial measurement module can be an accelerometer and a gyroscope. The accelerometer can measure the acceleration of the drone in all directions, thereby detecting the linear acceleration change of the center of gravity and judging whether the center of gravity has shifted. The gyroscope measures the angular velocity of the drone, which is used to stabilize the flight attitude and assist in judging the attitude changes caused by changes in the center of gravity. Through real-time data collection and processing, the flight control system can quickly sense changes in the center of gravity position and adjust the rotor speed accordingly, so as to maintain the rotor speed after the center of gravity changes, so as to ensure that the entire drone maintains a stable flight state.
[0024] The center of gravity adjustment mechanism 2 is provided at a position corresponding to the center of gravity inside the drone body 1 and is used to adjust the center of gravity of the entire drone to maintain the balance of the drone.
[0025] The control module is used to receive the wind direction data from the wind direction measurement module, the wind force F from the wind force measurement module, and the vertical distance L in the horizontal direction measured by the distance measurement module. x and the vertical distance L in the longitudinal direction y ; The control module calculates the torque generated by the longitudinal (pitch direction) wind force of the drone body 1 , the torque generated by the longitudinal wind ,judge 、 Is it greater than a preset torque threshold T? or When the control module starts to control the center of gravity adjustment mechanism activity, and calculates the rotation angle of the center of gravity adjustment mechanism 2 , calculate the vertical adjustment distance of the center of gravity adjustment mechanism 2 , where m is the mass of the center of gravity adjustment mechanism 2, is the acceleration due to gravity , X is the displacement of the lateral movement of the center of gravity adjustment mechanism 2, and Y is the displacement of the longitudinal movement of the center of gravity adjustment mechanism 2. The control module calculates and L values, respectively control the center of gravity adjustment mechanism 2 to rotate and move, so that the center of gravity adjustment mechanism 2 moves to a preset position to maintain the stability of the drone body 1 when subjected to wind force. When , the control module controls the center of gravity adjustment mechanism 2 to move and reset.
[0026] Among them, the derivation process for X and Y is: For the derivation of the moment balance formula in the pitch direction (longitudinal), the moment generated by the wind in the longitudinal direction , the torque generated by the longitudinal movement of the center of gravity adjustment mechanism 2 , is the acceleration due to gravity , according to the moment balance principle, ,Right now: , solve for the longitudinal displacement , similarly, solve the longitudinal displacement This is a relatively complex equation, which can be solved by simplification (the specific simplification process is omitted). However, in practical applications, in order to simplify the calculation, we can make some assumptions (such as assuming that X and Y are relative to L) x and L y Small, ignore high-order small quantities) further simplify the equation, for example, if we ignore the effect of X in the denominator (when X is small), we can get: , substitute the X value into the Y expression to get the simplified .
[0027] The process of the control module determining the wind direction action point is as follows: S1. Establish a three-dimensional rectangular coordinate system with the center of gravity of the drone as the origin, with the x-axis along the longitudinal direction of the fuselage (the nose is the positive direction), the y-axis along the lateral direction of the fuselage (the right side of the fuselage is the positive direction), and the z-axis perpendicular to the plane of the fuselage. S2. The wind vector in the received wind information data Decomposed into components in the x, y, and z directions , , ,in is the angle between the projection of the wind vector on the horizontal plane and the x-axis, is the angle between the wind vector and the horizontal plane; S3, through the formula , , , calculate the resultant force in the x, y, and z directions, and the resultant force vector , the magnitude of the resultant force ; S4. Calculate the position coordinates of the action point. Taking the xy plane as an example, the component force in the z direction is Generates a moment about the xy plane , according to the moment balance principle, ,but Similarly, the coordinates of the points of action in the x and y directions are obtained by calculating the moment balance of the yz plane and the zx plane. , ; The control module determines the horizontal and vertical distances between the wind direction point and the center of gravity of the drone body as follows: S1. Establish a coordinate system with the center of gravity of the drone as the origin, with the x-axis along the longitudinal direction of the drone (the direction of flight) (positive direction forward) and the y-axis along the transverse direction (left and right) (positive direction rightward). S2, according to the calculated coordinates of the action point ( , , ), determine the longitudinal distance = , lateral distance = , if 、 If it is positive, it means the wind force point is in front of the center of gravity; if it is negative, it means it is behind the center of gravity.
[0028] It should be noted that by adopting the above solution, when collecting image data in windy areas, the gravity adjustment system captures wind data in real time. After precise analysis and complex calculations, the adjustment parameters required for the center of gravity of the drone are accurately parsed. The control module drives the center of gravity adjustment mechanism to perform precise displacement operations based on these precise parameters, and can coordinate with the attitude adjustment module to adjust the flight attitude of the drone to solve the problem of limited adjustment ability of the attitude adjustment module in strong wind conditions, further improve the drone's ability to resist wind interference and adapt, and ensure that the drone can still maintain a highly stable flight attitude in strong wind environments, greatly improving the accuracy and continuity of image acquisition, and significantly reducing the difficulty of operation, so that the drone can complete image acquisition work efficiently and stably in such extremely challenging operating environments.
[0029] In addition, the drone's flight control system can set different priorities for rotor adjustment and center of gravity adjustment, and dynamically adjust them according to the flight status. In low wind conditions, rotor adjustment is given a higher priority to quickly correct the attitude; while in the stable flight phase, center of gravity adjustment can be optimized according to mission requirements and environmental changes to ensure the best overall performance of the drone. For example, when performing aerial photography missions, the flight control system will prioritize ensuring the stability of the drone's attitude to ensure clear images. At the same time, it will adjust the center of gravity in a timely manner according to the position and weight changes of the camera to improve flight efficiency and endurance. In strong wind conditions, rotor adjustment and center of gravity adjustment will work together to adjust the drone's flight attitude by adjusting both the rotor and the center of gravity simultaneously, improving the drone's ability to resist wind interference and ensuring that the drone can still maintain a highly stable flight attitude in strong wind environments.
[0030] Please refer to Figures 2 to 4 A circular cavity is provided inside the drone body 1, and a center of gravity adjustment mechanism 2 is provided in the circular cavity. The center of gravity adjustment mechanism 2 includes a counterweight, a rotary drive component and a linear telescopic component. The counterweight is located inside the drone body 1 at a position corresponding to its center of gravity. The rotary drive component is used to drive the counterweight to rotate horizontally relative to the inside of the drone body 1 by a preset angle, and the linear telescopic component is used to drive the counterweight to move linearly relative to the inside of the drone body 1.
[0031] Specifically, the counterweight is a power supply device. The reason for using the power supply device as a counterweight is that the power supply device itself has a certain mass, and without further increasing the original mass of the drone, it is used as a counterweight. The power supply device includes a protective housing 21, a battery 22, and a retractable connecting wire 23. The battery 22 is removably installed in the protective housing 21, and the two ends of the connecting wire 23 are respectively connected to the battery 22 and the conductive connection terminal of the drone body 1. The rotary drive element includes a rotary motor 24, which can be a reduction motor. The rotary motor 24 is fixedly installed in the drone body 1 at a position corresponding to the center of gravity. The rotating end of the rotary motor 24 is connected to the top of the protective housing 21 via a linear telescopic member. The linear telescopic part includes a rocker arm 25, an electric push rod 26 and a connecting slide 27. One end of the rocker arm 25 is fixedly connected to the rotating end of the rotating motor 24. The connecting slide 27 is slidably installed on the rocker arm 25. The connecting slide 27 is fixedly connected to the top of the protective shell 21. The electric push rod 26 is fixedly installed on one side of the rocker arm 25, and its telescopic end is fixedly connected to one side of the connecting slide 27. An annular limit guide groove 29 is provided on the inner side of the circular cavity. The support pulley 28 is rotatably installed on the end of the rocker arm 25 away from the rotating motor 24, and the support pulley 28 is in rolling contact with the annular limit guide groove 29.
[0032] It should be noted that when the above-mentioned center of gravity adjustment mechanism 2 is in use, the motor is rotated to drive the connecting slide 27, the rocker arm 25, the electric push rod 26 and the power supply device to rotate together. During the rotation of the rocker arm 25, the support pulley 28 and the annular limit guide groove 29 are rolled together to limit the rocker arm 25 so that it can move smoothly. At the same time, the electric push rod 26 contracts, which can drive the counterweight to move synchronously along the rocker arm 25. The counterweight stops contracting after moving a preset displacement. In this way, the counterweight can be driven to move quickly to the preset position to adjust the center of gravity of the drone body 1 so that the drone can still maintain a stable state when affected by wind.
[0033] The above describes an embodiment of this specific implementation method, but this embodiment is not limited to the above specific implementation method. The above specific implementation method is merely illustrative and not restrictive. Ordinary technicians in this field can also make many forms based on the inspiration of this embodiment, all of which are protected by this embodiment.
