Abstract

See full text

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.
