The LD491 used high-resolution cameras and GPS-RTK technology to perform aerial orthophoto mapping. By flying multiple routes and capturing images from various angles, it overcame ground obstacles. After processing, the data produced detailed orthophoto maps and 3D models of the mine. These outputs provided managers with a clear view of the terrain and dependable data for planning.

The Jinghong LD491 revolutionized inspections. It offered complete aerial coverage, capturing high-resolution images of the entire mining site. With its extended endurance and precise GPS positioning, it produced accurate orthophoto maps that matched engineering drawings. The drone eliminated the need for workers to climb hazardous slopes, reduced human error, and shortened inspection time from 24 hours to just 4 hours. Simultaneously, it reduced costs by 70%, demonstrating its value as a safer, quicker, and more cost-efficient inspection tool.

With the LD491, inspections became 10 times more efficient and significantly safer. Managers could now depend on clear digital maps instead of manual reports. The drone not only boosted productivity but also established a new standard for modern mine inspection.
