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° to each
other in the plane of the short sides, (short dimensions); further, these are
positioned with the longitudinal direction parallel with the transport
direction of the object to be measured and above the same, such that light and
contrast transitions are mirrored in these and recorded by the camera. The
device may be used for e.g. measuring thickness and width of laterally
conveyed timber in adjusting works.
