Claim One:
1. An apparatus comprising: a measurement unit having a laser ranging device and a camera; and a controller configured to calibrate the measurement unit with respect to a coordinate system of an object; the controller is configured to capture an image of a damaged region on the object with the camera, to select target points around a boundary of the damaged region on the image, and to determine two-dimensional image coordinates for the target points on the image; the controller is configured to determine angles for aiming the laser ranging device at each of the target points based on the two-dimensional image coordinates, to measure a distance to each of the target points with the laser ranging device based on the angles, and to calculate three-dimensional coordinates for each of the target points in the coordinate system of the object based on the distance measurement and the two-dimensional image coordinates for each of the target points.
