  • Publication number: 20190119080
    Abstract: Provided is a crane capable of allowing an operator to recognize an error in work information or in a number of windings set in a safety device. A main tension of a main wire rope is calculated from a main output torque of a main winch, a sub output torque of a sub winch, a main drum winding radius of the main winch, and a sub drum winding radius of the sub winch. An estimated hanging load, which is calculated from the main tension, a sub tension of a sub wire rope and the number of windings of the wire rope set in a safety device, is compared with an actual hanging load calculated from fluctuating thrust force and boom information. Thus, the suitability of a work kind or a winding number set in the safety device is determined.

  • Patent number: 9934563
    Abstract: Technologies are generally described for 3D object recognition through 2D image processing based on white balancing and object-rotation in machine vision systems. According to some examples, image recognition of an object captured with a camera under insufficient lighting may be achieved through white balancing. Processing cost reduction may be achieved in the learning process for image recognition through automatic generation of rotated 2D images of target objects to be detected, such as machine parts, from a small number of 2D images of a target object and generation of a 3D image of the target object from the rotated 2D images. Image recognition may thus be ensured even under insufficient lighting through execution of the image recognition process for multiple images and learning the successful recognition results. Some examples may be implemented in mechanical parts selection, where 2D images of the parts may be available beforehand.
