}Five steps, fully automated — from raw video to an interactive 3D scene.
RunSplat is the 3D reconstruction engine behind future SaaS platforms serving drone operators, surveyors, and inspectors across multiple countries.
Convert survey flights into accurate 3D Gaussian scenes for stockpile volume estimation, earthwork progress tracking, and site documentation — without LiDAR costs.
Inspect bridges, towers, wind turbines, and facades. Share a navigable 3D model with remote engineers — timestamped for damage progression comparison.
Produce photorealistic 3D maps of construction zones, agricultural land, or coastal areas — richer than orthophotos, embeddable in any web platform.
Turn a single drone flight into an immersive 3DGS scene for real estate, tourism, or media — embeddable in websites with one script tag.
Building a drone SaaS platform? RunSplat is designed to be your 3D reconstruction backend.
