AI Technical Summary

Technical Problem

Existing technologies lack a unified mathematical foundation for drone-based painting operations on spherical or quasi-spherical buildings, resulting in severe distortions in pattern mapping, reliance on manual intervention, fragmented workflows, and an inability to achieve industrialization and high-precision control.

Method used

By integrating real-scene 3D modeling, map projection, and UAV trajectory control, a spherical reference standard body is fitted using the least squares method to establish an auxiliary latitude and longitude spatial positioning system. Forward and inverse calculations of spherical-to-plane projection are performed to generate the coordinates of UAV spraying points, thus realizing a complete mathematical logic system.

Benefits of technology

It achieves high precision, automation, and consistency in drone spraying operations, eliminates pattern distortion, improves operational efficiency and safety, adapts to various building forms, and meets industrial standards.
