[0040] To make the technical problems, technical solutions, and beneficial effects to be solved by this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and are not intended to limit the scope of this application.
[0041] It should be noted that when an element is referred to as being "fixed to" or "set on" another element, it can be directly or indirectly on that other element. When an element is referred to as being "connected to" another element, it can be directly or indirectly connected to that other element. Unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.
[0042] It should be understood that the terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.
[0043] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.
[0044] As described in the background section, in practical applications, thermal infrared imaging technology is easily affected by the environment and prone to errors. Light spot, net radiation, atmospheric transmittance, wind speed, air humidity, distance, and emissivity are important reasons for temperature errors in thermal infrared imaging and are key factors affecting the accuracy of thermal infrared imaging temperature.
[0045] Among the factors affecting the accuracy of infrared camera temperature measurement, the distance from the object being measured is one of the key factors. The greater the measurement distance, the greater the error. Dust, water mist, and other media in the air can also affect the radiation temperature measurement results, leading to lower readings. Uneven surfaces of the object also cause differences in the distance between the infrared camera and different locations and areas. For example, the measurement accuracy of infrared camera temperature measurement is generally ±5%, while the error range for infrared imaging temperature measurement of three-dimensional concave and convex objects is much higher.
[0046] Based on this, the present application provides a plant canopy temperature measurement device. By integrating a lidar device and utilizing the lidar device's long effective detection range, it is possible to achieve real-time correction of the infrared camera's temperature measurement results, thereby improving the measurement accuracy of plant canopy temperature over long distances.
[0047] Figure 1 A schematic diagram of a plant canopy temperature measuring device provided in an embodiment of this application is shown below. Figure 1 As shown, the plant canopy temperature measurement device includes a data acquisition box 1, and may also include:
[0048] Infrared camera 2, installed in acquisition box 1, is used to acquire the original temperature at different target locations in the canopy of the plant to be monitored;
[0049] The lidar device 3 is installed in the acquisition box 1 and is used to acquire distance data between the infrared camera 2 and each target position.
[0050] Electronic compass 4, installed in data acquisition box 1, is used to acquire the camera shooting angle of infrared camera 2;
[0051] The processing device 5 is installed in the acquisition box 1 and has communication connections with the electronic compass 4, the infrared camera 2 and the lidar device 3 respectively. It is used to adjust the setting position of the infrared camera 2 when the distance data exceeds the predetermined distance range, and / or to adjust the camera shooting angle of the infrared camera 2 when the camera shooting angle exceeds the predetermined distance range.
[0052] In this embodiment, the size and structure of the acquisition box 1 are not limited and can be configured according to actual needs. Multiple devices can be integrated inside the acquisition box 1 to achieve the function of multi-source data fusion. For example, the acquisition box 1 can integrate an infrared camera 2, a lidar device 3, an electronic compass 4, and a processing device 5. Other devices can also be integrated on the basis of the above. This embodiment does not limit the installation position and connection relationship of each device inside the acquisition box 1. It can be configured according to the actual working principle of each device. For example, the processing device 5 can establish communication connections with the electronic compass 4, the infrared camera 2, and the lidar device 3 respectively.
[0053] Among them, infrared camera 2 can be used to collect the raw temperature at different target locations in the canopy of the plant to be monitored. The canopy of the plant to be monitored can refer to a certain canopy of the plant to be monitored for temperature. Different target locations can be understood as multiple points on the surface of the canopy of the plant to be monitored. By monitoring the temperature at multiple points on the surface of the canopy of the plant to be monitored, the impact of climate change on plant growth and ecosystem function can be observed. This is crucial for formulating strategies and measures to address climate change. At the same time, it can be used to assess the stability and resilience of the ecosystem, providing a scientific basis for the protection of biodiversity and the sustainable management of ecosystems.
[0054] The lidar device 3 can be used to collect distance data between the infrared camera 2 and each target position; the electronic compass 4 can be used to collect the camera shooting angle of the infrared camera 2. Furthermore, the infrared camera 2, lidar device 3, and electronic compass 4 can send their respective collected data to the processing device 5 for processing through a communication connection.
[0055] The processing device 5 can correct the original temperature at different target locations in the canopy of the plant to be monitored through a series of processing operations. For example, since the effective monitoring range of infrared thermal imaging technology is limited, the processing device 5 can adjust the setting position of the infrared camera 2 when the distance between the infrared camera 2 and the target location exceeds a predetermined distance range, and / or adjust the camera shooting angle of the infrared camera 2 when the camera shooting angle exceeds a predetermined distance range. This improves the accuracy of temperature monitoring at long distances by adjusting the setting position and / or shooting angle of the infrared camera 2, thus obtaining the corrected temperature corresponding to different target locations in the canopy of the plant to be monitored. The predetermined distance range can be set by relevant personnel according to actual conditions; for example, the predetermined distance range may include 0-2m. Building upon this foundation, the highly integrated lens makes the plant canopy temperature measurement device compact, lightweight, and easy to carry. Leveraging the effective detection range of the lidar device, which extends to within 25m, the device provides real-time correction to the infrared camera's temperature measurement results, improving the accuracy of temperature measurements within this 25m range. For example, compared to the measurement accuracy of a typical infrared camera, the plant canopy temperature measurement device in this embodiment achieves a 1.5% improvement in accuracy. Furthermore, the integrated electronic compass facilitates the measurement and selection of photographic angles during fieldwork, allowing for accurate acquisition of the target temperature at the desired angle.
[0056] This application provides a plant canopy temperature measurement device. By setting up an electronic compass and a lidar device, it can correct the infrared camera temperature measurement results when the distance data exceeds a predetermined distance range by adjusting the setting position of the infrared camera, and / or when the camera shooting angle exceeds a predetermined distance range by adjusting the camera shooting angle, thereby improving the measurement accuracy of plant canopy temperature at long distances.
[0057] In some embodiments, the plant canopy temperature measuring device further includes a mechanical motion device connected to the collection box for controlling the movement of the collection box.
[0058] The specific structure of the mechanical motion device is not limited. It can simply include a mechanical arm and a mechanical base to support the movement of the collection box, or it can include a more complex motion device, as long as it can control the movement of the collection box.
[0059] As one feasible embodiment, the mechanical motion device includes: a pitch axis motor, connected to one end of the acquisition box, for controlling the acquisition box to perform a first rotational action in a vertical plane by rotation, the first rotational action including an upward rotational action or a downward rotational action; a roll axis motor, connected to the pitch axis motor via a robotic arm, for indirectly controlling the acquisition box to perform a second rotational action in a horizontal plane by rotation, the first rotational action including a leftward rotational action or a rightward rotational action; and a translation axis motor, connected to the roll axis motor via a robotic arm, for indirectly controlling the acquisition box to perform translational motion along a straight line by rotation.
[0060] Among them, the pitch axis motor can make the acquisition box rotate around a horizontal axis (similar to an axis from left to right). For example, in some robotic arms or equipment, the rotation of the pitch axis motor can realize the up and down movement of the acquisition box in the vertical plane. For example, the rotation of the pitch axis motor can realize the adjustment of the up and down angle of the camera inside the acquisition box.
[0061] A roll axis motor allows the acquisition box to rotate around its own longitudinal axis (similar to an axis running from head to tail). For example, the rotation of the roll axis can enable the camera inside the acquisition box to perform left and right tilting movements in the horizontal plane. In some gimbal devices, the roll axis motor can enable the gimbal to perform left and right tumbling movements in the horizontal direction.
[0062] Translation axis motors primarily drive the data acquisition unit to move along a straight line. For example, in some linear guide rail systems, translation axis motors, through a transmission mechanism, can convert the motor's rotational motion into linear motion, allowing objects mounted on the guide rail to move linearly forward, backward, left, or right. Furthermore, by incorporating pitch axis motors, roll axis motors, and translation axis motors, multi-angle control of the data acquisition unit can be ensured, and anti-shake stability during operation is improved.
[0063] Furthermore, the rotation of the pitch axis motor, roll axis motor, and translation axis motor in the mechanical motion device can be autonomously and adaptively controlled through its own internal control logic according to the shooting requirements; or the mechanical motion device can be manually controlled according to the actual captured image of the acquisition box.
[0064] In some embodiments, a control device is also provided inside the acquisition box, and the plant canopy temperature measurement device further includes a wireless remote controller; the wireless remote controller establishes a wireless communication connection with the control device and is used to send action commands to the control device; the control device establishes a communication connection with the mechanical motion device and is used to control at least one of the pitch axis motor, roll axis motor, and translation axis motor in the mechanical motion device to rotate according to the action commands. Based on this, by using a wireless remote controller for motion control, the connection cable problem is solved, facilitating the use of the plant canopy temperature measurement device.
[0065] As one feasible embodiment, the wireless remote controller is equipped with a joystick; the joystick is used to send a first action command to the control device, the first action command being used to control the rotation of the pitch axis motor to adjust the pitch shooting angle of the infrared camera, and / or send a second action command to the control device, the second action command being used to control the rotation of the roll axis motor to adjust the horizontal shooting angle of the infrared camera.
[0066] As one possible embodiment, the wireless remote controller is equipped with a tactile sensor; the tactile sensor is used to send a third action command to the control device, the third action command being used to control the rotation of the translation axis motor to adjust the orientation data of the infrared camera.
[0067] Figure 2 This is a schematic diagram of the structure of a wireless remote controller provided in an embodiment of this application, as shown below. Figure 2 As shown, the wireless remote control can be configured with a joystick, a tactile sensor, an imaging area, a photo button, and a charging port. The shooting angle of the infrared camera can be controlled by the joystick to rotate the roll and pitch motors. Specifically, the user can send a first action command via the joystick to control the pitch motor, causing the infrared camera to rotate vertically, thus flexibly adjusting the camera's tilt angle. The user can also send a second action command via the joystick to control the roll motor, causing the infrared camera to rotate horizontally, thus flexibly adjusting the horizontal shooting angle. The orientation of the infrared camera can be controlled by the tactile sensor to control the translation motor. For example, the user can send a third action command via the tactile sensor to control the translation motor, causing the infrared camera to translate along a straight line, thus flexibly adjusting the camera's orientation data.
[0068] In addition, the imaging area can display the original temperature of different target locations in the canopy of the plant to be monitored, as captured by the infrared camera, and the photo button can be used by relevant personnel to trigger the infrared camera to take pictures.
[0069] In some embodiments, the plant canopy temperature measurement device further includes: a visible light camera, disposed in the acquisition box, and having a communication connection with the processing device, for acquiring coordinate data of different target locations in the canopy of the plant to be monitored.
[0070] Among them, the visible light camera can be used for target determination, so that the processing device can perform position calibration of the infrared camera and lidar equipment according to the coordinate data of different target positions, and realize the position registration and collaborative operation of the visible light camera, infrared camera and lidar.
[0071] In some embodiments, the plant canopy temperature measurement device further includes: a universal standard interface, one end of which is connected to a translation axis motor, and the other end of which is communicatively connected to a selfie stick or a drone, the selfie stick or drone being used to control the height of the data collection box.
[0072] For example, when dealing with large areas of contiguous planted vegetation, the plant canopy temperature measurement device can be configured with a universal standard interface and a retractable selfie stick can be connected to the universal standard interface for image acquisition. This solves the problem of the target being far away or difficult to reach due to obstacles, or the measurement results being affected by the surrounding background environment. Alternatively, the plant canopy temperature measurement device can also be equipped with a drone. By connecting the drone to the universal standard interface, it can be used to measure the canopy temperature of ultra-high or ultra-far-reaching plant targets.
[0073] In some embodiments, the plant canopy temperature measurement device further includes: a storage device for storing the corrected temperatures corresponding to different target locations in the plant canopy to be monitored; and a power supply device for electrically connecting to the acquisition box.
[0074] In some embodiments, the plant canopy temperature measurement device further includes: a wireless transmission device, which establishes a communication connection with a mobile terminal, for transmitting the corrected temperature corresponding to different target positions in the plant canopy to the mobile terminal.
[0075] Figure 3 A schematic diagram of another plant canopy temperature measuring device provided in this application embodiment is shown below. Figure 3 As shown, the data acquisition box can integrate a visible light camera, an infrared camera, and a lidar. A pitch axis motor can be connected to the outer side of the box. The other end of the pitch axis motor can be connected to a roll axis motor via a robotic arm, and the other end of the roll axis motor can be connected to a translation axis motor via the same robotic arm. A gimbal interface (i.e., a universal standard interface) can be configured on one side of the translation axis motor, allowing it to communicate with a selfie stick or drone.
[0076] Additionally, the plant canopy temperature measurement device can be equipped with an SD card slot, which can be used to store the corrected temperature corresponding to different target positions in the plant canopy to be monitored using an inserted SD card.
[0077] Figure 4 A schematic diagram of another plant canopy temperature measuring device provided in this application embodiment is shown below. Figure 4 As shown, the plant canopy temperature measurement device can be divided into a temperature correction system and a power supply module (i.e., power supply device) according to its function. The temperature correction system can be further subdivided into a data acquisition module, a high-performance computing board and a wireless communication module (i.e., wireless transmission device). The wireless communication module can establish a communication connection with a mobile terminal.
[0078] The data acquisition module integrates a visible light camera, an infrared camera, a lidar, and an electronic compass. The high-performance computing board may include a shooting mode configuration module, a shooting control module (i.e., a control device), a decoding module, a data preprocessing module, an algorithm calling unit (i.e., a processing device), a data compression module, a storage module (i.e., a storage device), and a data transmission module. The specific data processing process includes acquiring information through the data acquisition module, decoding the acquired information through the decoding module, and then performing data preprocessing through the data preprocessing module. This preprocessing includes positioning between different sensors, reading angles from the electronic compass, initial temperature measurement from the infrared camera, and format conversion, with the converted data displayed in pixels. The algorithm calling unit can perform temperature calculations and corrections on the read angle and distance data. The processed results can then pass through the data compression module, storage module, and data transmission module sequentially, and are transmitted to the mobile terminal via a wireless communication module. The final processed results may include infrared images before and after correction, with each pixel representing the temperature at different target locations. The mobile terminal can be a wireless remote control, a cloud-based device, or another receiving device. Based on this, by equipping high-performance computing boards and wireless communication modules, it is beneficial to quickly process, analyze, and store data.
[0079] Furthermore, this embodiment can also control the infrared camera to shoot based on the information collected by the data acquisition module through the shooting control module and the shooting mode configuration module. For example, the setting position of the infrared camera can be adjusted according to the distance data collected by the lidar device, and / or the camera shooting angle of the infrared camera can be adjusted according to the camera shooting angle collected by the electronic compass, thereby achieving the effect of temperature correction of the infrared camera.
[0080] Alternatively, target calibration can be performed based on the coordinate data collected by the visible light camera, achieving the effect of position calibration, registration, and collaborative operation among the visible light camera, infrared camera, and lidar.
[0081] Figure 5 This is a schematic diagram of the structure of a selfie stick provided in an embodiment of this application, as shown below. Figure 5 As shown, the selfie stick can be equipped with a gimbal interface, a telescopic rod, a fixing clip, a remote control bracket, a handle containing a rechargeable battery, and a charging port. The gimbal interface can be used to connect to a universal standard interface for plant canopy temperature measurement equipment. The telescopic rod can be used to adjust the length of the selfie stick, thereby flexibly adjusting the shooting height of the plant canopy temperature measurement equipment, solving the problems of targets being far away or difficult to reach due to obstacles, or the surrounding background environment being damaged and affecting the measurement results. The fixing clip can be used to fix the length of the selfie stick. The remote control bracket can be used to carry a wireless remote control that establishes a wireless communication connection with the control device inside the plant canopy temperature measurement equipment.
