Abstract
A method of locating a tool or device uses vision driven navigation augmented by inertial guidance. The vision navigation is in reference to fiducial markers in a room viewed by cameras mounted on the tool or device. The cameras calculate the location of the tool or device based on the fiducial markers. The combination of a camera fiducial location and inertial guidance assures knowing the tool's location and orientation regardless of interruption of line-of-sight. Using combined guidance provides a more robust and precise tool or device location and pointing. MEMS sensors and smart phone cameras can be used to make compact tools or devices.
