    Abstract: A method operational on a receiver device for decoding a codeword is provided. At least a portion of a composite code mask is obtained, via a receiver sensor, and projected on the surface of a target object. The composite code mask may be defined by a code layer and a carrier layer. A code layer of uniquely identifiable spatially-coded codewords may be defined by a plurality of symbols. A carrier layer may be independently ascertainable and distinct from the code layer and may include a plurality of reference objects that are robust to distortion upon projection. At least one of the code layer and carrier layer may have been pre-shaped by a synthetic point spread function prior to projection. The code layer may be adjusted, at a processing circuit, for distortion based on the reference objects within the portion of the composite code mask.

    Abstract translation: 提供了一种在用于解码码字的接收机设备上运行的方法。 经由接收器传感器获得复合码屏蔽的至少一部分，并且投射在目标对象的表面上。 复合代码掩码可以由代码层和载体层来定义。 唯一可识别的空间编码码字的码层可以由多个符号来定义。 载体层可以独立地确定并且不同于代码层，并且可以包括多个参考对象，其在投影时对于失真是鲁棒的。 代码层和载体层中的至少一个可以在投影之前通过合成点扩散函数预先形成。 可以在处理电路处根据复合代码掩码的部分内的参考对象来调整代码层的失真。

    Abstract: Aspects of the present disclosure relate to systems and methods for determining a resampler for resampling or converting non-Bayer patter color filter array image data to Bayer pattern image data. An example device may include a camera having an image sensor with a non-Bayer pattern color filter array configured to capture non-Bayer pattern image data for an image. The example device also may include a memory and a processor coupled to the memory. The processor may be configured to receive the non-Bayer pattern image data from the image sensor, divide the non-Bayer pattern image data into portions, determine a sampling filter corresponding to the portions, and determine, based on the determined sampling filter, a resampler for converting non-Bayer pattern image data to Bayer-pattern image data.

    Abstract: A device includes a first camera and a processor configured to detect one or more first keypoints within a first image captured by the first camera at a first time, detect one or more second keypoints within a second image captured by a second camera at the first time, and detect the one or more first keypoints within a third image captured by the first camera at a second time. The processor is configured to determine a pose estimation based on coordinates of the one or more first keypoints of the first image relative to a common coordinate system, coordinates of the one or more second keypoints of the second image relative to the common coordinate system, and coordinates of the one or more first keypoints of the third image relative to the common coordinate system. The first coordinate system is different than the common coordinate system.

    Abstract: Aspects of the present disclosure relate to systems and methods for structured light depth systems. An example active depth system may include a receiver to receive reflections of transmitted light and a transmitter including one or more light sources to transmit light in a spatial distribution. The spatial distribution of transmitted light may include a first region of a first plurality of light points and a second region of a second plurality of light points. A first density of the first plurality of light points is greater than a second density of the second plurality of light points when a first distance between a center of the spatial distribution and a center of the first region is less than a second distance between the center of the spatial distribution and the center of the second region.

    Abstract: An electronic device for generating a corrected depth map is described. The electronic device includes a processor. The processor is configured to obtain a first depth map. The first depth map includes first depth information of a first portion of a scene sampled by the depth sensor at a first sampling. The processor is also configured to obtain a second depth map. The second depth map includes second depth information of a second portion of the scene sampled by the depth sensor at a second sampling. The processor is additionally configured to obtain displacement information indicative of a displacement of the depth sensor between the first sampling and the second sampling. The processor is also configured to generate a corrected depth map by correcting erroneous depth information based on the first depth information, the second depth information, and the displacement information.
