<p>To facilitate the use of a crane, an angle feedback information on a rope angle (theta)of the crane is received, the angle feedback information being measured by means of a sensor at or adjacent to a trolley; and the angle feedback information is corrected by compensating an error caused by a speed change, and processed to provide movement instructions or other control information relating to the crane on the basis of real-time corrected angle information.</p> |
