GeoDrone
UAV 2D/3D orthomosaic stitching, DSM/DTM generation, dense point clouds, 3D mesh & flight planning software for Windows
Key Features of GeoDrone
Fast 2D & Accurate 3D UAV Orthomosaic Stitching
Supports both high-speed 2D planar stitching and full 3D Structure-from-Motion (Schur Complement Levenberg-Marquardt Bundle Adjustment, Brown-Conrady lens calibration, automatic QR/ArUco Ground Control Point detection) with Cloud-Optimized GeoTIFF (.tif) export.
DSM, Bare-Earth DTM & Contour Line Generation
Reconstructs dense Digital Surface Models (DSM) via 4-directional plane-sweep SGM and oblique MVS, automatically flattens water bodies via Otsu thresholding, filters buildings and vegetation into bare-earth DTMs, and exports .GeoJSON and AutoCAD .DXF contours.
Graph-Cut Seamline Optimization & Multi-Band Color Balancing
Computes optimal seamlines via Graph-Cut (α-expansion) to route around roofs and tall structures, supports interactive QGIS seamline editing (seamlines.geojson), and applies global gain/vignetting/gamma compensation with 4-level Laplacian pyramid blending.
Multi-GPU OpenCL Dense Point Clouds (LAS) & Textured 3D Meshes
Accelerates processing across multiple GPUs via OpenCL (NVIDIA, AMD, Intel) to generate dense .LAS point clouds with PatchMatch MVS, TSDF volumetric fusion + TGV/TV regularization (with 3D tree-canopy priors), and .PLY / Wavefront .OBJ meshes with 4096 px UV texture atlases.
Intelligent UAV Survey Flight Planner
Decomposes complex survey polygons into optimal flight blocks, plans single-grid, crosshatch, or 5-pass oblique (30° facade) missions with DEM terrain following, validates wind and shutter limits, and exports DJI Pilot 2 WPML (.KMZ) and Litchi (.CSV) missions.
VN-2000 Coordinate Systems & Offline 3D Web Viewer
Built-in VN-2000 (3° and 6° zones across all 63 Vietnamese provinces), WGS84, and UTM projections, paired with an interactive 3D viewer (MapLibre GL & Three.js) for distance, area, elevation profile, and cut/fill volume measurement plus standalone 3D viewer export.
