  • Patent number: 11215711
    Abstract: Detecting material properties such reflectivity, true color and other properties of surfaces in a real world environment is described in various examples using a single hand-held device. For example, the detected material properties are calculated using a photometric stereo system which exploits known relationships between lighting conditions, surface normals, true color and image intensity. In examples, a user moves around in an environment capturing color images of surfaces in the scene from different orientations under known lighting conditions. In various examples, surfaces normals of patches of surfaces are calculated using the captured data to enable fine detail such as human hair, netting, textured surfaces to be modeled. In examples, the modeled data is used to render images depicting the scene with realism or to superimpose virtual graphics on the real world in a realistic manner.

  • Patent number: 10830850
    Abstract: A method includes capturing a first set of optical images of the subject while a subject is lying on a table of a Magnetic Resonance (MR) scanner. This first set of optical images is acquired without any MR phased-array coils placed on the subject. While the subject continues to lie on the table of the MR scanner, a second set of optical images of the subject is acquired with the MR phased-array coils placed on the subject. Aside from the optical images, a set of MR images of the subject is acquired using the MR scanner. The first and second set of optical images are registered to the MR images. Following registration, the first and second set of optical images are used to determine element positioning of the MR phased-array coils in the set of MR images.

    Abstract: A 3D measurement method including; projecting a pattern sequence onto a moving object; capturing a first image sequence with a first camera and a second image sequence synchronously to the first image sequence with a second camera; determining corresponding image points in the two sequences; computing a trajectory of a potential object point from imaging parameters and from known movement data for each pair of image points that is to be checked for correspondence. The potential object point is imaged by both image points in case they correspond. Imaging object positions derived therefrom at each of the capture points in time into image planes respectively of the two cameras.

  • Patent number: 10788318
    Abstract: A three-dimensional shape measurement apparatus includes main pattern illumination parts, main image-capturing parts and a control part. The main pattern illumination parts obliquely illuminate grating pattern light in different directions toward a measurement target. The main image-capturing parts obtain a grating pattern image of the measurement target by receiving reflection light of the grating pattern light illuminated from the main pattern illumination parts and obliquely reflected by the measurement target. The control part produces height data of the measurement target using grating pattern images of the measurement target, or produces height data of the measurement target using image positions of plane images for the measurement target and texture information of the measurement target. The control part employs a grating pattern illuminated on the measurement target as the texture information to produce height data of the measurement target.

  • Patent number: 10787115
    Abstract: The angle-adjusting vehicular headlights comprise a housing, a swivel bracket, a distance checker, a tilt mechanism, a controller, and a headlight socket. The angle-adjusting vehicular headlights may change an elevation angle of a headlight responsive to a determination by the controller that an inclination angle of a vehicle has changed. As non-limiting examples, the inclination angle may have changed due to a cargo load that has been placed into the vehicle thus compressing the vehicle suspension or the inclination angle may have changed due to the cargo load being removed from the vehicle and the resulting decompression of the vehicle suspension. angle-adjusting vehicular headlights may generally be deployed in pairs.

  • Patent number: 10772173
    Abstract: A light fixture including an array of LED light sources corresponding to a color channel of the light fixture, a driver circuit configured to drive the array of LED light sources, and a controller. The controller controls the operation of the light fixture to receive a direct drive signal related to a direct drive signal value for the array of LED light sources, determine an output of a reference light fixture based on the direct drive signal, determine a value for a color channel drive signal based on the output of the reference light fixture, and provide a control signal to the driver circuit to cause the driver circuit to apply the color channel drive signal having the value to the array of LED light sources. The value for the color channel drive signal results in an output of the light fixture that matches the output of the reference light fixture.
