Camera motion tracking

May 10th, 2009

There will be an infrared camera looking at part of the stage from the top. Using the software MotionTrackOSC, we can do blob-tracking, resulting in a number of tracked areas, as movement occurs in them.
The camera feed will also be available for use with other software.

Infrared motion detector

May 8th, 2009

From Wikipedia:

A Passive InfraRed sensor (PIR sensor) is an electronic device that measures infrared (IR) light radiating from objects in its field of view. PIR sensors are often used in the construction of PIR-based motion detectors (see below). Apparent motion is detected when an infrared source with one temperature, such as a human, passes in front of an infrared source with another temperature, such as a wall.
All objects emit what is known as black body radiation. It is usually infrared radiation that is invisible to the human eye but can be detected by electronic devices designed for such a purpose. The term passive in this instance means that the PIR device does not emit an infrared beam but merely passively accepts incoming infrared radiation.

Amount in workshop: 4 (as part of the “environmental unit”).
