Introduction

When working in the 3D workflow, OnlyView can automatically perform 3D calibration of the position, rotation, and lens of the projectors. For this, additional hardware is required: specific cameras that will analyze the scene.

What AutoCal does:

  • It guesses the position of the 3D cameras and projectors

  • It provides a 3D scan of the scene, as a point cloud

  • It re-aligns the cameras, the projectors and the point cloud so that it matches the real scene

  • The end-result is that each Media Server automatically outputs the correctly-deformed image. No manual deformation (for instance, with WarpNet) is required, except for optional fine-tuning.

What AutoCal doesn't do:

  • It does not provide a 3D mesh. You can take the output point cloud and model the scene based on it, but it is a manual process.

  • It is not a tracking system. Auto-calibration takes some time, with very visible light patterns being projected, so it is not something you can do during the show.
