THREE-DIMENSIONAL INFORMATION DETECTION DEVICE
Provided is a three-dimensional information detection device having a configuration in which detection accuracy of three-dimensional information of a measurement target object is not lowered even in a case where an optical system that includes a projection unit, a first imaging unit and a second imaging unit is covered with a light transmissive cover so that the optical system is not exposed to the outside. The three-dimensional information detection device includes the projection unit that projects an image pattern onto a measurement target object, the first imaging unit and the second imaging unit that respectively image the image pattern, a transmissive cover that covers the optical system that includes the projection unit, the first imaging unit, and the second imaging unit, and a calculation unit that calculates three-dimensional information of the measurement target object on the basis of the image pattern that is imaged using the first imaging unit and the second imaging unit. At least a part of a mounting surface of the optical system is formed by a light absorbing member, and the first imaging unit and the second imaging unit are disposed out of a region to which reflected light that is regularly reflected from the cover in projection light of the image pattern is directly incident.
Two-camera triangulation scanner with detachable coupling mechanism
A three-dimensional (3D) scanner having two cameras and a projector is detachably coupled to a device selected from the group consisting of: an articulated arm coordinate measuring machine, a camera assembly, a six degree-of-freedom (six-DOF) tracker target assembly, and a six-DOF light point target assembly.
Broken wheel detection system

Systems and method for filling apparel with gases, fluids, or fluid-like solids to enable the accurate three-dimensional capture of apparel by three-dimensional scanning and stereo photogrammetry
The present invention provides a system for accurate three-dimensional (3D) capture of apparel by 3D scanning and stereo photogrammetry. One or more flexible deflated bladders are inserted into an apparel and inflated by a filling media source. The bladder is inflated to measure at least one of size of the apparel, tensile strength of the fabric of the apparel, or cross section perimeter of the apparel. A rotating structure is anchored onto the stable structure to uniformly rotate all the fixed points of the apparel. One or more 3D scanners are configured to scan the inflated apparel on the stable structure and export the scanned data to one or more software applications. The processor retrieves the 3D scanned dimensional data from a searchable database and compares the given apparel's dimensions with one or more apparels' dimensions in the database to provide the customer with size recommendation via a display.
IMAGING APPARATUS AND IMAGING METHOD
An imaging apparatus includes a circuitry configured to perform depth analysis of a scene by time-of-flight imaging and to perform motion analysis in the scene by structured light imaging, wherein identical sensor data is used for both, the depth analysis and the motion analysis.
SYSTEM AND METHOD FOR 3D SCANNING
A system for capturing a 3D image of a subject includes a detection device which is structured to capture images of the subject and surrounding environment, a projection device which is structured to provide a source of structured light, and a processing unit in communication with the detection device and the projection device. The processing unit is programmed to: analyze an image of the subject captured by the detection device; modify one or more of: the output of the projection device or the intensity of a source of environmental lighting illuminating the subject based on the analysis of the image; and capture a 3D image of the subject with the detection device and the projection device using the modified one or more of the output of the projection device or the intensity of the source of environmental lighting illuminating the subject.
THREE-DIMENSIONAL ADDITIVE MANUFACTURING APPARATUS
A three-dimensional additive manufacturing apparatus for additive manufacturing by irradiating a powder bed placed in a build surface area with is configured to project a fringe pattern over the build surface area and detect unevenness in the build surface area, based on image data obtained by capturing an image of the fringe pattern. The projection unit and the imaging unit are disposed so as to avoid an irradiation region of the beam.
DISTANCE MEASURING DEVICE, IMAGING APPARATUS, MOVING DEVICE, ROBOT DEVICE, AND RECORDING MEDIUM
A distance measuring device includes an imaging optical system having an optical filter and an imaging element in which a plurality of pixel portions is arranged. The optical filter is divided into three regions, the first region has a first spectral transmittance characteristic, and the second region and the third region a second spectral transmittance characteristic in which light having a longer wavelength compared to the first spectral transmittance characteristic is transmitted. The first pixel portion that configures the imaging element includes a first photoelectric conversion unit and receives light that has passing through the first region. The second pixel portion that configures the imaging element includes second and third photoelectric conversion units, and receives light that has passed through each of the second region and the third region. A distance information acquiring unit acquires distance information corresponding to parallax of image data based on each of the output signals from the second and third photoelectric conversion units.
Camera system, animal related system therewith, and method to create 3D camera images
A camera system, an animal related system therewith, and a method for creating a 3D image of an object, the camera device including a 3D camera device to capture images of the object, a processing device to determine a 3D image from the captured images, and a mover device to move at least a part of the 3D camera device with a reciprocating movement. Providing a movement to the camera device provides a less noisy and more accurate 3D image of the object, in particular in a case of a soiled camera device.
RANGING OBJECTS EXTERNAL TO AN AIRCRAFT USING MULTI-CAMERA TRIANGULATION
Apparatus and associated methods relate to ranging an object nearby an aircraft by triangulation using two simultaneously-captured images of the object. The two images are simultaneously captured from two distinct vantage points on the aircraft. Because the two images are captured from distinct vantage points, the object can be imaged at different pixel-coordinate locations in the two images. The two images are correlated with one another so as to determine the pixel-coordinate locations corresponding to the object. Range to the object is calculated based on the determined pixel-coordinate locations and the two vantage points from which the two images are captured. Only a subset of each image is used for the correlation. The subset used for correlation includes pixel data from pixels upon which spatially-patterned light that is projected onto the object by a light projector and reflected by the object.
