🔧 Kalibrate: Camera Calibration to Unreal Lens Made Simple
Kalibate is a two-part tool designed for creators, VFX artists, and virtual production teams who need precise camera calibration for Unreal Engine.
Part 1: Calibrate with Confidence
Simply feed your camera video into the app—Kalibrate automatically detects and tracks checkerboards across frames, extracting the necessary lens distortion and camera intrinsics. The result: a clean, structured JSON file containing everything needed for lens calibration.
Part 2: Convert for Unreal
Run the included script to transform the JSON data into a native Unreal Engine Lens File (.uasset), ready for use in your virtual production pipeline. No guesswork, no manual editing—just plug-and-play precision.
🚀 Key Features:
-
✅ Automatic checkerboard tracking from camera footage
-
✅ JSON export of calibrated lens data
-
✅ Scripted conversion to Unreal Lens .uasset
-
✅ Supports both nodal and distortion parameters
-
✅ Compatible with Unreal Engine’s Lens Calibration System
Whether you're building virtual sets or matching CG to plate, KALIBRATE brings real-world optics into Unreal with accuracy and ease.
Software runs live from PC connected to any camera such as Blackmagic, Webcam or USB.
No tracking system required!
Print a checkerboard and the software automatically detects the board using industry leading algorithms and automatically takes the photos.
Takes only 1 person to operate!
A simple Python scripts executed in Unreal converts the JSON file into a Unreal Engine capable lens file
Use it for VFX or Virtual Production!
