CODA

Codamotion Industrial system is a motion capture system that delivers accurate 3D real time data to solve challenges involving automated manufacture and the control of repetitive production movements.

Applications:

Crash testing dynamics Vibration analysis Ergonomics research Sports research Training techniques Injury prevention

How it works

LED markers and the drive boxes that power them are attached to the body. The drive boxes receive infrared synchronising pulses from the CODA sensor unit. Circuitry in the drive box then flashes the markers at a specific time sequence. Each drive box and marker is individually numbered and can easily be tracked at the computer. As they move at each sensor a shadow is cast by a mask on a linear detector array and is cross correlated with the same pattern in real time using a DSP processor.

Setting up

It is important before the system works that the marker origins are set. This is to determine the x, y and z coordinates. This will provide more accurate 3D motion video at the computer.
