Tracking to project interactive content with one video projector

KineMotion is a real-time tracking solution fully developped by Modulo Pi. It can be used to perform dynamic projection mapping, interactive video effects, automatic follow spot, spatial audio, and more.
For more information, please check the KineMotion specification sheet .

In this tutorial, we will use KineMotion to achieve the following:

• Track a hand in which a LED stands
• Track a rectangular surface such as a board
  

Requirements for these exercises

• 3 x OptiTrack cameras – at least – that can see the Beacon
• 1 x KineMotion tracking system with:
  - 1 x Beacon emetter: The LEDs are connected to this device
  - 1 x Wand: To get the cameras information (Pitch, Yaw, Roll), its XYZ position, its lens information (Shift, optic ratio, field of view) and place it in a 3D space
  - 1 x Square: To calibrate the ground position in the Kinetic Designer’s 3D environment
  - 1 x Active synchro RF box: To synchronise both cameras and Kinetic Designer
• 1 x Kinetic Designer workstation
• 1 x Kinetic V-Node server
• 1 x RJ45 Switch PoE to power the cameras

*For this project, we chose a basic setup with 3 OptiTrack cameras only. However, the number of cameras required depends of your scenography size, and how far you need to track the LED in this area.
