Overview

BlackTrax Overview

BlackTrax (BT) is a vision based tracking system available from CAST, capable of tracking both objects and people. Tracking data from BT can be input into and mapped to objects or props within the Disguise visualiser.

The BT system uses an array of cameras placed on the stage rig to observe IR markers (small LEDs) placed on the talent or prop. These active markers generate rigid body information that is sent to Disguise as they are observed by an array of cameras mounted on the truss/staging. As long as the marker is observable by two cameras an accurate positional fix is possible

The markers are attached to a small BT Beacon unit (usually attached to the talents belt). This unit provides power and control to the IR markers.

BlackTrax can integrate with in two ways:

  • Actor/talent tracking

  • Prop/screen tracking (used for movable scenic pieces)

A BlackTrax server contains the software programs required for configuring a BT system including BTwyg, BlackTrax, and Motive.
