Open the CIPO recordAbstract From the Canadian patent
A calibration system is provided for calibrating a sensor with respect to an external reference frame associated with manufacturing gauging station (200). A target calibration device (600) is positioned at a vantage point to detect and calibrate its reference frame in relation to the external reference frame. A reference target having at least three non-coplanar reflective surfaces (406) is illuminated by the structured light emanating from the sensor.

Why it's free to use
- Filed January 15, 2002. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended January 15, 2022.

- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
