Optical detection system for lift crane

A method of determining a condition of a crane component of a crane, the crane comprising a carrier unit, a superstructure mounted on the carrier unit and including a boom, a cable extending from a free end of the boom, a lifting appliance coupled to the cable, and an optical detection system comprising an image capture device mounted on the superstructure and positioned to have a field of view in which the lifting appliance is disposed, and configured to capture an image, and an optical detection computer comprising a processor and a computer-readable storage medium, the method comprising:

• detecting, with the optical detection computer, one or more objects in the captured image, the one or more objects selected from:
• the lifting appliance, the cable, a load coupled to lifting appliance, an object remote from the crane and a marker;
• analyzing, with the optical detection computer, the one or more detected objects;
• and
• determining, with the optical detection computer, a condition of a crane component based on the analysis of the one or more detected objects.

A method of controlling a crane operation, the crane comprising a carrier unit, a superstructure mounted on the carrier unit and including a boom, a cable extending from a free end of the boom, a lifting appliance coupled to the cable, an optical detection system comprising an image capture device mounted on the superstructure and positioned to have a field of view in which the lifting appliance is disposed, and configured to capture an image, and an optical detection computer comprising a processor and a computer-readable storage medium, and a crane control system operably coupled to the optical detection system, the method comprising:

• detecting, with the optical detection computer, one or more objects in the captured image, the one or more objects selected from:
• the lifting appliance, the cable, a load coupled to lifting appliance, an object remote from the crane and a marker;
• analyzing, with the optical detection computer, the one or more detected objects;
• determining, with the optical detection computer, a condition of a crane component based on the analysis of the one or more detected objects;
• and
• controlling, with the crane control system, a crane operation based on the determined condition.
