WheelWatch

Measure wheel position and posture while moving

Product Description

WheelWatch

WheelWatch can monitor and analyze wheel behavior while the vehicle is moving or on a test bench using a camera to measure at high speed marker information attached on the wheels. The actual wheel behavior can be measured due to non-contact 6 DOF measurement.
Not only for wheel movement measurement, it can also be used for wheel test on test bench with shaker. It can also synchronize with an external device using a trigger signal from the synchronization box. when real-time mechanical control on test bench is required, digital to analog output is also possible. WheelWatch can integrate with various information relating to testing, output the results and analyze it.
