Claim One:
1. An apparatus comprising: a measurement unit having a laser ranging device and a camera mounted on a gimbal assembly; and a controller configured to calibrate the measurement unit with respect to a coordinate system of an object by controlling the measurement unit to perform measurements on reference points at known locations in the coordinate system of the 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 aiming angles for aiming the laser ranging device at each of the target points based on the two-dimensional image coordinates; the controller is configured to control motors of the gimbal assembly to aim the laser ranging device at the target points, to measure a distance to the target points with the laser ranging device, and to calculate three-dimensional coordinates for the target points in the coordinate system of the object based on the distance measurement and the two-dimensional image coordinates for the target points.
