Oqus Camera series

Oqus – Qualisys' workhorse

Motion Capture

The core of the Oqus marker-based cameras is the ability to calculate marker positions with highest accuracy and speed. Hundreds of markers can be measured at thousands of frames per second with ten, fifty of even more cameras - and everything run off an ordinary laptop! No workstations needed. No external hub needed. The system becomes truly mobile and very easy to setup.

Speed

Speed comes in many shapes in an Oqus based system. An extreme data reduction and fast marker calculations lays the ground to achieve a total system latency of under 4ms, this includes both in-camera processing and 3D/6DOF reconstruction. Camera models with high-speed mode featuring sub-sampling to enable higher frame rates while keeping the entire field-of-view. Add true high-speed video functionality and with just a click of the mouse, turn the motion capture camera into a high-speed video camera.

Flexibility

Add WiFi to your Oqus camera and the system can be run off a laptop without cables attached. Having difficulties choosing between a passive or an active motion capture system? Look no further, the Oqus cameras can use either! Passive markers are hard to beat when it comes to ease of use and flexibility. But in some applications sequence coded active markers are the best choice. Go Oqus and don't worry about making the wrong decision.
