Vicon

Advanced

A British optical motion-capture company, a common source of ground-truth pose in robotics labs.

Vicon is a British optical motion-capture company based in Oxford, part of the listed company Oxford Metrics. The first Vicon product launched in 1979 out of a subsidiary of Oxford Instruments, becoming independent after a 1984 management buyout. Its systems surround a capture area with multiple infrared cameras that track reflective markers attached to a person or object, computing millimeter-accurate 3D position and orientation in real time. Beyond film animation and sports biomechanics, robotics labs commonly use it to supply external ground-truth pose for quadrupeds, drones, and robot arms — for evaluating state-estimation error — or to record human motion that is later retargeted onto humanoid robots. It competes directly with OptiTrack and is generally priced higher.

ExampleWhen training a quadruped to run, researchers record the body's true position with Vicon and compare it against the robot's own estimated odometry to see how much it has drifted.
