Abstract: In order to be able to detect a three-dimensional relative position on a container load cargo with respect to a hoisting accessory, a detecting system for a container's location is provided with a plurality of CCD cameras disposed vertically downward on the hoisting accessory, which is mounted on a crane for conveying containers, and photographing a plurality of corner fittings mounted on the upper surface of the container load cargo, respectively; a distance finder for determining a distance between the hoisting accessory and the container load cargo; an image processor for image-processing video signals from the CCD cameras to detect two-dimensional coordinates of the corner fittings on the upper surface of the container load cargo; and an arithmetic and control unit for performing an arithmetical operation of the three-dimensional relative position on the surface of the container load cargo with respect to the hoisting accessory on the basis of the two-dimensional coordinates of the plurality of corner fit

Abstract: An apparatus for recognizing a position, a diameter and a width of a cylindrical object such as a coil made of thin steel plate being wound while observed by a TV camera in unmanned manner. The coil is irradiated with laser light while the laser light is moved in the direction perpendicular to an axial direction of the coil. An image data by the laser light is obtained from a difference of image data in the case where the coil is irradiated with the laser light and in the case where the coil is not irradiated with the laser light. The image data is analyzed to obtain data such as the position and the like. In order to improve an S/N ratio of the image data, the difference signal is binarized and then integrated for a frame. Influence of the background light can be minimized and a memory capacity for the image data can be reduced.
