Method for lifting steel coil to fixed saddle truck by unmanned travelling crane

The invention discloses a method for hoisting a steel coil to a truck with a fixed saddle by an unmanned travelling crane, which comprises the following steps of: 1) installing a scanner on the unmanned travelling crane, continuously scanning the truck by the scanner, and calculating the coordinates and the height value of the head of the truck to form a height value curve; 2) according to the height value curve, identifying the height value of the truck plate of the truck; (3) identifying the feature points of the saddle by taking the height value of the sweeping board as a reference; 4) on the basis of the saddle feature points, identifying and calculating center coordinates of available saddles; 5) feeding back a calculation result to a library management system; and (6) the warehouse management system starts the unmanned travelling crane to carry out warehouse-out hoisting of the steel coil according to the center coordinates of the saddle. The scanner is used for scanning the contour line of the truck, t
