Abstract
A measuring device 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 (EDM) and one or more sensors for determining the EDM's orientation. The measuring device comprises an image capture device (ICD) 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 is arranged to receive data from the one or more sensors and the ICD. The controller can associate an image with the orientation of the EDM during exposure of the image, locate one of the measurement points within the image, and use the location of the measurement point within the image and the EDM's orientation to establish the direction of the measurement point with respect to the measuring device.
