Product Overview

Underwater

The world's most versatile underwater motion capture cameras
Qualisys underwater cameras are the world’s only commercially available optical motion capture cameras for underwater use and are designed for mobility, robustness and trouble-free operation. All cameras are pressure tested to a depth of 40m and is corrosion-protected for use in salt water tanks or chlorinated swimming pools. Weight and volume is balanced to give the camera neutral buoyancy for easy handling in water.

Miqus Underwater
At just over 2kg, the Miqus is almost four times lighter and four times smaller than the 7+u, making it easier to deploy in small tanks or pools where you are closer to your subject and measurement distance is shorter.

Miqus Underwater is available in the marker cameras  M3u and M5u and as a video camera. The widest field-of-view option is 45% wider than the 7+u, making it much easier to deploy at close quarters when wide angle is needed to cover the volume effectively.

7+ Underwater
Qualisys 7+ Underwater is a robust, high resolution camera for long range measurements suitable for a wide range of applications including vessel design, naval research, fishing industry and sports science.

The camera’s strobe consists of 12 high power deep blue LEDs that can illuminate markers at more than 30m distance. The custom-designed housing is made of hard anodized aluminum and pressure tested to 40m depth. The powerful LEDs are thermally connected to the housing to get the most efficient cooling for best performance.

Miqus Video Underwater
Miqus Video Underwater is available in color and monochrome, and can be used together with the motion capture cameras to enable 3D video overlay as reference for your captures.

The Underwater Video cameras may also be used as a standalone video solution, bridging the gap between small, handheld consumer devices and more expensive cameras that are typically used in industrial settings. The Miqus underwater video-cameras stream MJPEG compressed full-HD video in 85 fps over standard gigabit Ethernet.

Underwater Human Motion
Qualisys underwater cameras has many use cases within underwater biomechanics such as lower body gait analysis or studying the kinematics of swimmers.

Combine Qualisys underwater cameras with our skeleton solving software to capture underwater motions performed by actors, to be used in games and film.

Marine
An underwater motion capture system is an essential tool in the development and testing of underwater vehicles and equipment. Examples of use include the tracking of free-running AUVs, underwater objects towed in a towing tank, mooring lines, fish net trawl doors and oil pipeline motions, just to mention a few.

Combining above and underwater
By combining Qualisys groundbreaking underwater cameras with an above water camera system, in what is known as a ‘Twin system’ setup, above- and underwater movement can be merged together into a single capture.

Integrations
Qualisys Track Manager takes full advantage of the features of the camera, such as the ability to stream 6DOF data to 3rd party applications in real-time. Synchronization with external equipment is also possible.
