First came Katan, then came CamSchnappr. What's next? How can you calibrate even more devices together like cameras, projectors, and VIVE Trackers? Over the past few years Harvey Moon has been working on a number of different ways to calibrate faster and more easily using TouchDesigner. At the beginning of this talk Moon will explain how he calibrated a projector to the VIVE world coordinates by re-building CamSchnappr for single point input. After this, he will deconstruct CamSchnappr and add the Ret Error output. Moon will lead a discussion about the function of OpenCV’s calibrateCamera and how it can be used in different contexts.
Moon will also present a project that uses fiber optics to automatically calibrate a scale city model, with a live demo of four corner calibration on a fiber sensor array. In closing Moon will briefly describe how to calibrate the intrinsics of a camera lens using OpenCV in TouchDesigner in addition to showing a system that uses cameras and structured light to calibrate three projectors. Attendees will be invited to ask questions at the end of the presentation.
