Description

Technical Field

[0001] The utility model belongs to the field of UAV aerial surveying, and particularly relates to a surface correction device for UAV aerial surveying in mining areas Background Technique

[0002] In view of the requirements of UAV aerial surveying in mining areas, it is particularly important to develop a special surface correction device. When conducting UAV aerial surveying in mining areas, common problems include deformation of the established phase control devices due to uneven ground, which affects the measurement accuracy. Since the UAV captures orthophotos during flight, the uneven ground will affect the ground phase control devices, especially in mining areas with large slopes or complex terrains

[0003] To effectively solve this problem, a one-meter by one-meter surface correction device is proposed. This device is designed to be placed on uneven ground, and through its stable and standardized surface, it ensures the accuracy and stability of the phase control device during UAV shooting. The core design of the device includes a flat square base, so that no matter how uneven the ground is, the phase control points above can be ensured not to deform

[0004] In addition, this device also takes into account the requirements of in-office correction. After the UAV finishes shooting and returns to the office for in-office processing, this standardized phase control device can be used as a correction reference to correct the images captured by the UAV according to its exact size in reality. This not only improves the accuracy of data processing, but also simplifies the in-office correction process and improves work efficiency

[0005] By deploying this surface correction device, the data quality and accuracy of UAV aerial surveying in mining areas can be significantly improved, providing more reliable support for mining area management and planning. This technology is suitable for both vast open-pit mining areas and areas with complex terrains that are difficult to access, enhancing the application ability of UAVs in mining surveying Content of the Utility Model

[0006] The utility model provides a surface correction device for UAV aerial surveying in mining areas to solve problems such as uneven terrain and unstable control point setting when using ground phase control devices in traditional UAV aerial surveying in mining areas

[0007] To achieve the above technical effects, the utility model is realized through the following technical solutions

[0008] A surface correction device for UAV aerial surveying in mining areas includes: fine adjustment screw, spirit level bubble, adjustment platform screw, horizontal arm, phase control point, adjustable platform, base, vertical column, coarse adjustment button

[0009] The center position of the adjustable platform is the phase control point, and vertical columns and fine adjustment buttons are respectively arranged at the four corners of the adjustable platform from the inside to the outside, and a level bubble is arranged in the middle of the vertical column and the fine adjustment button on one side; horizontal arms are arranged on the four sides of the adjustable platform, and an adjustment platform screw is arranged on the horizontal arm;

[0010] Furthermore, the adjustable platform is provided with a fine adjustment screw and an adjustment platform screw to precisely adjust the size and height of the adjustable platform, and a level bubble is also provided to ensure that the platform remains level on any terrain;

[0011] Furthermore, the lower part of the vertical column is fixedly connected to the base, and a coarse adjustment button is provided on the vertical column. The surface correction device used for drone aerial survey in mining areas is supported by four vertical columns to ensure that the device can be safely and stably deployed even on unstable ground;

[0012] Furthermore, the phase control points are precisely positioned using RTK measurement technology, ensuring the correction accuracy of subsequent drone shooting data.

[0013] The beneficial effects of the utility model are:

[0014] The surface correction device adopted by the utility model can automatically adjust the size and level correction without manual fine operation, which greatly improves the correction efficiency of UAV aerial survey. The automated correction operation not only saves human resources, but also completes the accurate setting of ground control points in a short time, speeding up the progress of UAV aerial survey operations.

[0015] The level bubble and fine adjustment screw equipped in the calibration device can monitor and adjust the horizontal state of the platform in real time, so that the equipment can be calibrated quickly and accurately in complex terrain. This ensures the accuracy of the calibration points, avoids data errors caused by uneven terrain, and improves the quality and reliability of aerial survey data.

[0016] The adjustable design of the surface correction device allows it to adapt to different terrains without direct human operation, reducing the risk of contact for operators in complex terrains. At the same time, the automated operation during the correction process reduces the working time of personnel in harsh environments, reducing the workload and operational risks of operators.

[0017] The device's highly automated technology and precise sensing capabilities enable it to respond to terrain changes in a timely manner, avoiding calibration errors or other operational accidents. Therefore, the calibration process is safer and more reliable, ensuring the safety of operators and aerial survey equipment, while ensuring high-quality aerial survey data.

[0026] Embodiment 1

[0027] In this embodiment, before starting the UAV aerial survey operation, the engineering team used a special surface correction device to set up detailed ground control points in the mining area, ensuring the accuracy and reliability of the UAV shooting data. First, they determined the key areas where ground control points needed to be set according to the pre-obtained terrain data. Then, they input this information into the control system of the surface correction device to formulate the optimal location setting path and operation plan.

[0028] The surface calibration device activates its precise positioning system, equipped with a spirit level bubble 2 and fine adjustment screws, and starts moving forward along the preset path. The spirit level bubble continuously monitors the horizontal state of the platform to ensure that the device can work stably on uneven ground. At the same time, RTK technology is used to accurately measure the position of the phased points 5 to provide accurate ground reference points for the UAV.

[0029] When the surface calibration device reaches each predetermined control point position, the adjustment system accurately adjusts the platform to ensure it is completely horizontal. The adjustable platform 6 is designed with variable dimensions for easy adjustment according to specific requirements, and the adjustment platform screw 3 allows the operator to finely adjust the size of the platform.

[0030] Once the set position and horizontal state are confirmed, the phased points are precisely set in the center of the platform. Throughout the process, the operator can maintain real-time communication with the control center through the communication module on the device (similar to communication device 5), providing the position and operation progress of the surface calibration device. The operator can remotely monitor the operation of the device at any time and make adjustments when necessary.

[0031] Embodiment 2

[0032] In this embodiment, before starting the UAV aerial survey, the engineering team used a surface calibration device designed specifically for mining areas to perform surface calibration work to ensure the orthophoto image accuracy of the UAV. First, the engineering team deployed the surface calibration device at the designated positions in the mining area, which were obtained through prior topographic analysis and UAV pre-survey. The adjustable platform 6 of the calibration device was set to the default size of 1m×1m and accurately placed on the ground to ensure the stability of the base 7 on the uneven ground.

[0033] Then, the operator used the fine adjustment screw and the coarse adjustment button 9 to precisely adjust the calibration device horizontally and vertically to ensure that the spirit level bubble 2 indicates that the platform is completely horizontal. RTK equipment was used to accurately measure the coordinates of the phased points 5 for precise correction of the UAV images during the later in-house processing.

[0034] When everything is set up, the UAV equipped with high-precision photography equipment starts the aerial survey according to the preset flight path. During the process, the ultrasonic radar 1 and the camera 3 continuously monitor the flight state of the UAV and the ground conditions. After the aerial survey is completed, the obtained image data will be compared with the phased point data on the surface calibration device, and the control board 2 is used to process and correct any errors in the images to ensure the accuracy and usability of the data.
