Abstract
A method and device for determining position coordinates of a target object is disclosed. The method includes positioning a target device on the target object, transmitting a laser beam onto the target device, reflecting the laser beam off of the target device, recording an image of the target device by a camera device with the reflected laser beam as a light reflection in the image, and determining a focus of the light reflection in the image. The reflected laser beam is received and a distance to the target object is calculated from the received beam. A first offset is calculated from a focal length of the camera device, the calculated distance to the target object, and a first image coordinate of the focus of the light reflection in the image. The position coordinates of the target object are calculated from the distance and the first offset.
