A laser scanner and a system with a laser scanner for measuring an environment. The laser scanner includes an optical distance measuring device, a support, a beam steering unit rotatably fixed to the support which rotates around a beam axis of rotation. The beam steering unit includes a mirrored surface which deflects radiation used in the optical distance measurement and an angle encoder for recording angle data. The optical distance measurement is performed by a progressive rotation of the beam steering unit about the beam axis of rotation and the continuous emission of a distance measurement radiation, the emission being made through an outlet area arranged in the direction of the mirrored surface on the support, the receiving optics for receiving radiation are 10 arranged on the support, and wherein the outlet area has a lateral offset with respect to the optical axis of the receiving optics.

An inspection device for contactless three-dimensional inspection of a circular, mechanical component with toothing having a main axis of rotation. The device is configured to scan the teeth by at least one first pair of laser measurement modules and rotationally drive the component about the main axis relative to the laser measurement modules. The device then rebuilds a virtual three-dimensional representation of the component using data coming from said scanning and performs a dimensional inspection using the three-dimensional representation. Each pair of modules includes a first module oriented towards a first face of a tooth and a second module oriented towards a second face of a tooth. The modules are oriented relative to the component so that during a rotation of the component, the laser measurement modules scan the first and second faces of each tooth throughout their thickness and depth.

A nut measuring device that is configured to be surroundably mounted a nut so as to measure and subsequently display the size thereof. The nut measuring device includes a body having a first end and a second end. The first end of the body includes an opening wherein the opening is contiguous with a channel. The channel extends inward into said body and includes a hollow passage. A plurality of sensors are circumferentially mounted to the channel and extend the entire length thereof. The sensors are configured to detect and provide measurement of a nut adjacent thereto. A processor is operably coupled to the plurality of sensors and receives data signals therefrom. A display screen is formed in the outer surface of the body and is operably connected to the processor. The display screen displays the size of the nut disposed in the channel.

A dimensioning system that analyzes a distance map for null-data pixels to provide feedback is disclosed. Null-data pixels correspond to missing range data and having too many in a distance map may lead to dimensioning errors. Providing feedback based on the number of null-data pixels helps a user understand and adapt to different dimensioning conditions, promotes accuracy, and facilitates handheld applications.

A system to digitally scan an object in three dimensions is disclosed. The system includes a server system, a memory system, a website and a scanner that scans an object and transfers any number of scanner data to the memory system, the scanner data resides on the digitally scan an object in three dimensions non-transitory storage media and includes any number of object dimensions such as length, width and height of the object, a three-dimensional object file and any number of raw video or any number of images of the object. The system includes a corresponding method for digitally scanning an object in three dimensions and a non-transitory computer storage media having instructions stored thereon which, when executed, execute the method for digitally scanning an object in three dimensions.

Spaced-apart light spots are projected in a light pattern on a target surface lying in a target plane. A range spot is projected at a position on the target surface to find a target distance to the target surface. An image of the target surface, light pattern, and range spot is captured along an imaging axis that is perpendicular to an imager plane of an imager. A controller determines an angular relationship between the imager and target planes based on the light pattern in the captured image, determines a scale relationship between the target surface and the imager based on the position of the range spot in the captured image, displays a compensated image of the target surface that is corrected in tilt by the angular relationship and in scale by the scale relationship, and determines dimensions of the target surface based on dimensions of the displayed compensated image.

The attenuation and other optical properties of a medium are exploited to measure a thickness of the medium between a sensor and a target surface. Disclosed herein are various mediums, arrangements of hardware, and processing techniques that can be used to capture these thickness measurements and obtain three-dimensional images of the target surface in a variety of imaging contexts. This includes general techniques for imaging interior/concave surfaces as well as exterior/convex surfaces, as well as specific adaptations of these techniques to imaging ear canals, human dentition, and so forth.
