Abstract:
A measuring device ( 10 ) for determining the location of one or more measurement points relative to the measuring device. The measuring device is arranged to be coupled to a non-contact distance measuring device or EDM ( 12 ) and one or more sensors ( 16 ) for determining the orientation of the EDM. The measuring device comprises an image capture device or ICD ( 20 ) operable to output digital images and being arranged to be coupled to the EDM such that the ICD moves in known registration with respect to the EDM. A controller ( 28 ) is arranged to receive data from the one or more sensors and the ICD. The controller is configured to: a) associate an image with the orientation of the EDM during exposure of the image; b) locate one of the measurement points within the image; and c) use the location of the measurement point within the image in combination with the EDM orientation to establish the direction of the measurement point with respect to the measuring device.

Claim (Index 7):
A measuring device according to  claim 5 , wherein the optical axis of the ICD is not coaxial with EDM measurement axis and the controller is configured to perform an EDM alignment function comprising:\n (d) use intrinsic and extrinsic parameters of the ICD together with the orientation of the EDM during exposure of the image to project a measurement point in the image out as a three dimensional ICD ray in world coordinates; (e) control the drive system to align the EDM with a point on the ICD ray and then perform a distance measurement; (f) obtain an EDM target point corresponding to the measured distance and the current EDM direction; (g) calculate the perpendicular distance of the EDM target point from the ICD ray; and (h) perform an optimisation procedure that repeats steps (e) to (g) one or more times in order to find an EDM direction that reduces and in some cases minimises the distance of the EDM target point from the ICD ray.
