Breakthrough in New Frontiers！5mm Orthophotos Achieved at 100m Flight Altitude – Ushering in a New Era of Areal Control for AI Databases！

Recently, Meshdynamics (Beijing)  Information Technology Co., Ltd., in collaboration with Shanghai Kanrong Information Technology Development Co., Ltd. and Beijing Suce Technology Co., Ltd., has successfully delivered a project. Leveraging the Fengjiang Intelligent FJD Trion AM150A 90mm integrated drone system, the initiative achieved aerial orthophoto capture with a resolution exceeding 5mm at a 100-meter safe flight altitude, using a multirotor UAV platform.

       This test was conducted using the DJI M300RTK UAV, the 150-megapixel medium-format camera of the FJD Trion AM150A, Bentley iTwin Capture Modeler software, and Racurs PhotoMod software. In future practical applications, safe flight operations can be carried out 50 meters away from the centerlines of railways, highways, and power lines. With two flight routes, full coverage of the target area can be achieved via their overlapping area—not only does this keep operations away from the centerlines to ensure safer flights, but it also enables the capture of high-precision stereoscopic imagery directly above the centerlines. This surpasses the resolution limits of existing remote sensing imagery, allowing clear visualization of micro-details.

       Notably, the 5mm ultra-high-resolution image data can serve as "reference control images" for AI database development. Its high-precision, high-density spatial information extends the role of traditional point-based control to areal control, enabling the creation of large-scale, high-precision areal control image data. This provides highly accurate training samples for AI deep learning, effectively enhancing the generalization ability and robustness of AI models.
