摘要： A method of recognizing a shape using a multizone time-of-flight (ToF) sensor includes receiving, by a processor, ToF data indicating an object located within a field of view of the multizone ToF sensor, the field of view being divided into zones. The ToF data includes signal information corresponding to each zone of the field of view of the multizone ToF sensor. The ToF data may include a two-dimensional array of zone data, each of the zone data including distance information and additional signal information. The method further includes recognizing, by the processor, the object as the shape using the signal information. Recognizing the shape may include filtering, by the processor, the ToF data through an artificial intelligence (AI) model to create AI output data and recognizing the shape using the AI output data.

摘要： The method, apparatus and computer program product estimate the depth to objects within a scene that is captured by first and second cameras of a mobile terminal. A method includes determining, based upon an image including an eye of a user captured by a first camera of a mobile terminal and an image of a scene captured by a second camera of the mobile terminal, two or more angles of a geometric shape defined by the eye, the mobile terminal and an object of the scene. Based upon the image captured by the first camera, the method also determines a first distance from the first camera to the eye. The method further estimates the depth to the object in the scene relative to the mobile terminal based upon the first distance and one or more angles of the geometric shape defined by the eye, the mobile terminal and the object.

摘要： Systems and methods for sensing depth may utilize a baseline matrix for correlating different baselines with their corresponding centers of diffraction. In one particular example, a depth sensing system includes: a projector including: a light source and a metasurface, where the light source illuminates the metasurface at different transverse locations such that the metasurface projects light in different transverse locations onto an object; a receiver including an image sensor configured to receive light that is reflected from off the object, where the projector and the receiver are a fixed distance apart such that the light in different transverse locations has a plurality of centers of diffraction which correspond to different baselines which are the distance between the centers of diffraction and a fixed point of the receiver, and where the light received by the image sensor corresponds to different disparities based upon the depth of the object.

摘要： A system for inspecting a reflective surface includes a first imaging assembly configured to take a first image of the reflective surface. The first image includes depth information. The system also includes a second imaging assembly configured to take a second image of the reflective surface. The second image includes contrast information. The system further includes a processor configured to acquire the first image and the second image, estimate a depth profile of the surface based on the depth information, correlate the depth profile with the second image, and identify a feature of the reflective surface based on the correlation.

摘要： A method for characterizing structures etched in a substrate, such as a wafer is disclosed. A bottom of the structure is embedded in the substrate, the substrate having a top side in which the structures are etched and a bottom side opposite to the top side. The method includes the following steps: illuminating the bottom of at least one structure with an illumination beam issued from a light source emitting light with a wavelength adapted to be transmitted through the substrate, acquiring, with an imaging device positioned on the bottom side of said substrate, at least one image of a bottom of the at least one structure through the substrate, and measuring at least one data, called lateral data, relating to a lateral dimension of the bottom of the at least one HAR structure from the at least one acquired image. A system implementing such a method is also disclosed.

摘要： 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 arranged on the support, and wherein the outlet area has a lateral offset with respect to the optical axis of the receiving optics.

摘要： Eyewear including a sensor integrated into frame of eyewear. In one example, the sensor comprises a strain gauge, such as a metallic foil gauge, that is configured to sense and measure distortion of the frame when worn by a user and under different force profiles, by measuring a strain in the frame when bent. The measured strain by strain gauge is sensed by a processor, and the processor performs dynamic calibration of image processing based on the measured strain. The distortion measured by the strain gauge is used by the processor to correct calibration of the cameras, and the displays.
