Abstract: A device for touchless measuring of thickness and width of an object travelling along a straight path, based on the use of CCD video camera and laser. The device, by means of installed cameras, laser(s) and two parabola-shaped mirrors, measures both thickness and width of an object as the center line thereof passes directly below the width measuring camera. The device is intended to be coupled to a computer or PC or PLS. Communicating equipment does not become "stuck", occupied with reading measuring values even if the object to be measured comes to rest within the measuring area. Parabola-shaped mirrors are mounted parallel in the longitudinal direction, and with the concave and mirror-coated sides angled 90.degree.

Abstract: A device for automatic, contactless and optical video measuring of the dimension of one or more objects at rest or being conveyed parallel along a straight path. In the measuring system a CCD video camera (5) through two parabola-shaped mirrors (3, 4), in the course of 6 to 12 lines, senses a section of the objects (7) to be measured, perpendicular to the direction of motion thereof. The parabola-shaped mirrors contribute to avoiding erroneous measurements, which otherwise arise due to camera optics and the varying distance to the objects to be measured. The object to be measured is illuminated obliquely by means of two elongated light sources (1, 2). Camera and mirrors are mounted in a dust-tight cabinet, allowing the contrast information of the object to be measured to pass only through an elongated aperture (8), covered by a glass adapted to shut out light of unfavorable wave length. The video information is electronically converted into TTL levels and digitized.
