Abstract: A camera system includes two or more sensor arrays and an optical path. The sensor arrays are on the same sensor chip. Each sensor array includes the same field of view (FOV) as each other sensor array. The optical path includes a main lens and a metalens that are shared by each sensor array, and a microlens associated with each sensor array. The metalens splits incident light into different spectrums of light and directs each respective spectrum to a corresponding sensor array. The different spectrums of light include at least two of visible light, near infrared light, shortwave infrared and longwave infrared, and at least one sensor array includes single-photon avalanche diodes. The image processor that provides image processing, object recognition and object tracking and/or image fusion functionality may be on the same sensor chip as the sensor arrays.

Abstract: A range sensor and a method thereof. The range sensor includes a light source configured to project a plurality of sheets of light at an angle within a field of view (FOV); an image sensor, wherein the image sensor is offset from the light source; collection optics; and a controller connected to the light source, the image sensor, and the collection optics, and configured to simultaneously determine a range of a distant object based on direct time-of-flight (TOF) and a range of a near object based on triangulation.

Abstract: Using the same image sensor to capture both a two-dimensional (2D) image of a three-dimensional (3D) object and 3D depth measurements for the object. A laser point-scans the surface of the object with light spots, which are detected by a pixel array in the image sensor to generate the 3D depth profile of the object using triangulation. Each row of pixels in the pixel array forms an epipolar line of the corresponding laser scan line. Timestamping provides a correspondence between the pixel location of a captured light spot and the respective scan angle of the laser to remove any ambiguity in triangulation. An Analog-to-Digital Converter (ADC) in the image sensor generates a multi-bit output in the 2D mode and a binary output in the 3D mode to generate timestamps. Strong ambient light is rejected by switching the image sensor to a 3D logarithmic mode from a 3D linear mode.

Abstract: A system for calculating. A scratch memory is connected to a plurality of configurable processing elements by a communication fabric including a plurality of configurable nodes. The scratch memory sends out a plurality of streams of data words. Each data word is either a configuration word used to set the configuration of a node or of a processing element, or a data word carrying an operand or a result of a calculation. Each processing element performs operations according to its current configuration and returns the results to the communication fabric, which conveys them back to the scratch memory.

Abstract: A structured-light pattern for a structured-light system includes a base light pattern that includes a row of a plurality of sub-patterns extending in a first direction. Each sub-pattern is adjacent to at least one other sub-pattern, and each sub-pattern is different from each other sub-pattern. Each sub-pattern includes a first number of portions in a sub-row and a second number of portions in a sub-column. Each sub-row extends in the first direction and each sub-column extends in a second direction that is substantially orthogonal to the first direction. Each portion may be a first-type portion or a second-type portion. A size of a first-type portion is larger in the first direction and in the second direction than a size of a second-type portion in the first direction and in the second direction. In one embodiment, a first-type portion is a black portion and the second-type portion is a white portion.

Abstract: An imaging unit includes a light source and a pixel array. The light source projects a line of light that is scanned in a first direction across a field of view of the light source. The line of light oriented in a second direction that is substantially perpendicular to the first direction. The pixel array is arranged in at least one row of pixels that extends in a direction that is substantially parallel to the second direction. At least one pixel in a row is capable of generating two-dimensional color information of an object in the field of view based on a first light reflected from the object and is capable of generating three-dimensional (3D) depth information of the object based on the line of light reflecting from the object. The 3D-depth information includes time-of-flight information.
