Method for lifting and transporting a load using an autonomous forklift truck

A method for lifting and transporting a load using an autonomous forklift comprising a vertically movable fork provided with at least one arm, the method comprising:

• a step of the forklift receiving an assigned mission to move the load to be lifted and transported that comprises a theoretical value of at least one dimension of the load;
• a step of moving the autonomous forklift so that the autonomous forklift is in front of the load to be lifted and transported;
• a step of acquiring at least one image of the load by means of at least one camera fastened to the autonomous forklift centered relative to the vertically movable fork and having a line of sight oriented forward along a longitudinal axis of the forklift;
• a step of determining an actual value of the dimension of the load on a basis of the image obtained in the acquisition step;
• a step of comparing the actual value of the dimension of the load determined in the determination step and the theoretical value of the dimension of the load received in the receiving step;
• and
• a step of stopping the forklift if a difference between the actual value of the dimension and the theoretical value of the dimension is greater, as an absolute value, than a predefined limit value, or
• a step of lifting and transporting the load if the difference between the actual value of the dimension and the theoretical value of the dimension is less than or equal to, as an absolute value, the predefined limit value.
