Astra + Projector for Interactive Systems

Hi has anyone worked on interactive systems using an Astra and a projector? For example, the Astra detects a box, and the projector would project patterns on the box? I am wondering how to calibrate the projector to get its lens distortions, as well as to get the extrinsic parameters between the projector and the camera.

Hello, a few years later… Yes I worked with Astra for a few years, and now trying to port Astra plus cameras for my AR projection framework : GitHub - natar-io/PapARt: Paper Augmented Reality Toolkit - interactive projection for Processing
