ELECTRONIC LEVELING APPARATUS AND METHOD |
摘要 |
<p>An electronic leveling apparatus for optically measuring a height difference relative to a leveling staff comprises a telescope, a camera fixed to the telescope, a first actuator for rotating both said telescope and said camera in a horizontal plane about a fixed vertical axis of the apparatus, and a controller. The camera has a depth of focus that is at least twice a depth of focus of the telescope. The controller uses a first output signal from said telescope to output a leveling signal representing a detected height difference. The controller uses a second output signal from said camera to identify a representation of a leveling staff and to control the first actuator based on the identified representation of the leveling staff . Furthermore, a method for optically measuring a height difference of an electronic leveling apparatus relative to a leveling staff is provided.</p> |
