An arrangement of a 3D measurement device according to the invention comprises an image source in order to produce consecutive images on a surface of an object, a camera to take pictures of the surface, and a processor unit in order to compare the pictures of the camera with said images. The arrangement comprises also a first area and a second area on the images. The arrangement further comprises at least one double detector in order to detect the illuminated first area and the illuminated second area, and a drive unit in order to trigger at least one camera. The drive unit is arranged to trigger the camera if the double detector indicates that a state of the first area changes and a state of the second area changes.

Methods, devices and systems describe compact and simple deflectometry configurations that can measure complex shapes of freeform surfaces. One deflectometry system includes a first panel and a second panel positioned at an offset position from each other to provide illumination for an object. The second panel, positioned closer to the object, is operable as a substantially transparent panel, and as a pixelated panel to provide structured light patterns. The system also includes two or more cameras positioned on the second panel an is operable in a first mode where the first panel provides a first structured illumination and the second panel is configured as a substantially transparent panel that allows the first structured illumination from the first panel to transmit toward the object. The system is also operable in a second mode where the second panel is configured to provide a second structured illumination for illuminating the object.

A system and method for finding dents on an automobile is described herein. The system, in one embodiment, can be a booth that has a support structure, a plurality of wall sections, a roof, and interior surface defined at least in part by the wall sections and the roof, and a first geometric repeating pattern on a first region of the interior space.

The present disclosure relates to an inspection apparatus for visually inspecting a substantially dark area. The inspection apparatus includes an inspection casing having a sidewall extending between a casing inspection end and a connecting end, an omnidirectional video camera mounted to the casing inspection end of the inspection casing; and a light-emitting assembly at least partially contained in the inspection casing. The sidewall of the inspection casing has a light-permeable section extending along 360 degrees and the light-emitting assembly is configured to emit light through the light-permeable section and from the casing inspection end, and away therefrom. An inspection system is also described.

In one aspect, there is provided a system including at least one processor; and at least one memory including program code which when executed by the at least one processor causes operations including capturing an image of at least a portion of a surface of an object; generating, from the captured image, pixel intensity data; in response to generating the pixel intensity data, determining, based on a height error model, height error data, wherein the height error data indicates an uncertainty of at least one height measurement of the object; and determining, based on the height error data, whether the object satisfies a threshold criteria for acceptance of the object. Related system, methods, and articles of manufacture are also disclosed.

A computer-implemented method for measuring the three-dimensional geometry of a mineral glass-based glazing during or just after a temperature shaping operation. The method implements digital processing and calculations, based on the principles of stereocorrelation, of digital images of a random light pattern projected onto the surface of a transparent glazing. It makes it possible in particular to determine the shape or the three-dimensional geometry of a transparent glazing, the surface of which not be totally opacified and/or which radiates under the effect of temperature.

A method for measuring the optical quality of a delineated region of a glazing, the delineated region being intended to be placed in front of an acquiring or measuring device such as a camera. The method is particularly suitable for measuring the optical quality of a delineated region of a transportation-vehicle glazing, such as an airplane or automobile windshield, in front of which an optical device for recording images or a device for measuring the environment outside the vehicle is placed with a view to enabling operation of an advanced driver-assistance system of the vehicle.

An embodiment provides an inspection apparatus for a display device, including: a light supplier that supplies light to a surface of the display device; an inspection pattern portion positioned between the display device and the light supplier; a measurement portion that measures reflected light reflected from the surface of the display device; and a processor that processes data of the reflected light measured by the measurement portion, wherein the processor includes a calibration data portion including calibration data and a calibrator calibrating the data using the calibration data of the calibration data portion.

A device for detecting defects on at least one painted surface may include: a source configured to emit electromagnetic radiation, in at least one first spectral band, in order to project a beam of the radiation onto the at least one painted surface; a video camera sensitive in at least one second spectral band and configured to obtain images of the at least one painted surface in a zone where the beam of the radiation emitted by the source is projected; and a diffuser configured to intercept at least part of the radiation emitted by the source and to make more homogeneous a spatial distribution of radiation intensity over the at least one painted surface. A spectral working band of the device is the at least one first spectral band, the at least one second spectral band, or an intersection of the at least one first and second spectral bands.

According to an embodiment, an optical apparatus includes an illumination unit, a light-receiving unit and a processing unit. The illumination unit can illuminate an object with a plurality of pattern rays including rays with different wavelengths simultaneously. The light-receiving unit includes a pixel that can receive the rays from the object to disperse at least two of the different wavelengths included in the pattern rays. The processing unit acquires information on the object based on a result of the pixel of the light-receiving unit receiving the pattern rays with which the illumination unit illuminates the object simultaneously.
