3D Video Tracking System

February 1, 2012

Specialised Imaging Ltd. (Tring, Hertfordshire, UK) has announced a new version of its Trajectory Tracker video tracking system that correlates high-speed video data with 3D visualization and measurement information. Designed to enable engineers to understand the flight behavior of high-speed objects, the SI Tracker 2 adds full, motorized 3-axis remote control and pseudo-real-time scan correction. The lightweight system tracks objects in flight using a computer-controlled, triggered rotating mirror positioned in front of a high-speed video camera.

The SI Tracker 2 observes the inflight behavior of high-speed objects over more than 100 meters, and with a tracking accuracy of better than 0.2 degrees. The resulting slow-motion record of the test object in-flight allows accurate diagnosis of events such as fin deployment and motor burn time, as well as calculation of pitch, yaw, and spin rate.
