The testing machine further comprises a wrapping station provided with a testing drum to be wrapped by the film coming out from the pre-stretching station, a plurality of measuring groups to perform measurements of dimensional and/or physical parameters of the reel and of the film, and a plurality of testing groups to perform respective tests and measurements on the film in order to determine mechanical and physical properties thereof.

The disclosure relates to a method for controlling a glass sheet heating furnace using information describing a glass load including a plurality of glass sheets. The method includes transporting the glass sheets toward a heating furnace, before thermal treatment, photographing the glass load by a camera to obtain a camera image, sending first information of the camera image to a computer, on the basis of which the computer determines a first value of a dimension of the glass load and selects a value of at least one adjustment parameter of the heating furnace on the basis of the first value before the glass load has been transferred into the heating furnace, and reading second information by a line scanner, which is sent to the computer, on the basis of which the computer determines a second value of the dimension of the glass load.

There is provided an operating method of an optical positioning system including: capturing an image frame of a detected surface, which has interleaved bright regions and dark regions, using a field of view and a shutter time of an optical sensor counting a number of edge pairs between the bright regions and the dark regions that the field of view passes; calculating an average value of the image frame; calculating a ratio between the calculated average value and the shutter time; determining that the field of view is aligned with one of the dark regions when the ratio is smaller than a ratio threshold; and determining that the field of view is aligned with one of the bright regions when the ratio is larger than the ratio threshold.

A method for determining a dimension between the back and the cutting edge of a vibrating blade mounted on a cutting head includes successively of acquiring a digital image of the blade mounted on the cutting tool so a line corresponding to a cutting edge of the blade and a line corresponding to a back of the blade are visible in the image, determining on the digital image along a straight line perpendicular to the line corresponding to the cutting edge of the blade the pixels comprised between the line corresponding to the cutting edge of the blade and the line corresponding to the back of the blade, and calculating a filtered dimension between the back and the cutting edge of the blade from the number of pixels comprised between the line corresponding to the cutting edge of the blade and the line corresponding to the back of the blade.

A device to monitor and analyze physical properties of moving web of slit plastic film tapes moving over a rotating roller. The device has an optical sensor and camera box having an optical source which emits a beam of homogeneous light transmitter, and a receiver having a line scan camera to receive light sent by transmitter. The device also has an initial measurement unit, a PLC controller, a central processing unit (CPU) and a display monitor. The device moves end to end over the rotating roller to capture images of tapes and data on light beam and sends them to PLC and CPU and then to the display monitor. The images sent by camera and the light beam data sent by the receiver are analysed to determine the physical properties such as edge fibrillation and colour, thickness, width, and the uniformity of spacing of the tapes.

An image processing apparatus, an image processing method and a recording medium capable of detecting a plurality of breaks in a coating material and an inclined break of the coating material are provided. The image processing apparatus includes a grouping unit for extracting coating areas representing a coating material from an input image acquired by imaging an inspection object linearly coated with the coating material and grouping the coating areas for each sequence of linear parts, a calculation unit for calculating a line width in an orthogonal direction of a linear part for each of the linear parts in a plurality of portions of the coating area including end portions of the linear parts, a break detecting unit for detecting a break in the coating material based on the calculated line widths, and an output unit for outputting an indication representing occurrence of the break when the break is detected.

A vehicular trailer assist system includes a control that includes an image processor for processing image data captured by the camera representative of at least a portion of a trailer hitched to the vehicle. The control determines whether the trailer has been previously hitched to the vehicle. Responsive to the trailer not being previously hitched, the control operates in a trailer initial calibration mode. Responsive to the control recognizing the trailer, the control operates in a recognized trailer calibration mode. The control obtains calibration data unique to the hitched trailer. The control, responsive to obtaining the calibration data, processes image data captured by the camera using the calibration data to locate the current position of the trailer relative to the vehicle. The control, responsive to locating the current position of the trailer relative to the vehicle, determines a trailer angle based on the located current position.

An apparatus for inspecting or observing a material web, a process of inspecting the material web and a method for operating the apparatus for inspecting or observing the material web are provided. The apparatus has a guiding device through which the material web is guided and a camera including a field of view and configured to record an image of the front side within the field of view. An incident light transmitter is configured to illuminate the front side with incident light, and a background panel is arranged on the rear side of the material web within the field of view. The background panel includes a diffuser plate, a light guide plate, a reflecting surface, and a light source configured to couple light into the light guide plate which is configured to uncouple the light to illuminate the rear side of the material web with transmitted light.
