In order to create precise integrations of computer-generated (CG) imagery with live-action video, it’s essential to have a virtual camera within Unreal Engine that mirrors the real-world camera used for capturing the video footage. This requires the virtual camera to not only emulate the position and orientation of the physical camera but also to synchronize its movement with the exact timing of the video feed. This synchronization is crucial for ensuring each frame of the video is perfectly aligned with the camera’s position at every moment.

At Geotech, we’re enhancing the capabilities of our Lens Calibration Plugin to make this process smoother and more accurate. The Camera Calibration plugin is designed to simplify the camera and lens calibration process in the Editor. This process produces the data needed to precisely align the virtual camera with the physical camera’s spatial position and to accurately replicate the lens distortion of the physical camera. The plugin features the new Lens File asset type, which stores all the calibration data for the camera and lens.
Additionally, the Camera Calibration plugin boasts a comprehensive lens-distortion pipeline. This feature takes the calibrated distortion data and applies it as a highly accurate post-process effect to the CG render. This effect can be directly added to a Cinecamera Actor for use in the Movie Render Queue, or it can be applied to the CG layers in Composure.
The tools and framework provided by the plugin are designed to be extensible and adaptable, accommodating a broad spectrum of lenses and workflows. This extension of the Lens Calibration Plugin by Geotech underscores our commitment to providing advanced and flexible tooling solutions for professionals in the field.
