Overview
Constructing large-scale urban 3DGS assets remains constrained by equipment costs and delayed quality feedback. Preset surveys can leave complex surfaces insufficiently observed, with defects discovered only after reconstruction. OpenFlyScan is a quality-guided aerial reconstruction system for consumer drones that integrates a GS quality model, a reacquisition planner, and a custom-designed mobile app.
The model learns from GS rendering errors to predict regional quality before target-scene reconstruction. These predictions guide complementary reacquisition strips, executed through the app, which also supports automated oblique surveys and data transfer without additional onboard hardware. Initial-survey and additional images are jointly reconstructed.
Reconstructed Scenes
Field captures and reconstructions of real-world datasets. Simulation scenes are excluded.
Method
The mobile app manages capture and mission execution, while a remote workstation predicts regional reconstruction quality and plans targeted reacquisition.
GS quality model
The GS quality model consists of a frozen pretrained Pi3X backbone and a trainable cross-modal Quality Predictor. It combines multi-view image features, feed-forward geometry, and relative camera geometry to predict regional reconstruction quality.
Base supervision uses measured regional GS rendering errors; Sparse supervision uses weak targets constructed by removing supporting observations.
