摘要： Systems and techniques are described for determining disparity information. For instance, a method for determining disparity information is provided. The method including: obtaining a plurality of cost functions; determining a first disparity for a center pixel of a first region of pixels at least in part by comparing one or more minima of a cost function of the center pixel to one or more minima of cost functions of other pixels in the first region; determining a second disparity for the center pixel at least in part by comparing one or more minima of a cost function of a center pixel of a second region to one or more minima of cost functions of other pixels in the second region, including the center pixel of the first region; and determining a third disparity for the center pixel of the first region based on the first disparity and the second disparity.

摘要： An electronic imaging device and method for image capture are described. The imaging device includes a camera configured to obtain image information of a scene and that may be focused on a region of interest in the scene. The imaging device also includes a LIDAR unit configured to obtain depth information of at least a portion of the scene at specified scan locations of the scene. The imaging device is configured to detect an object in the scene and provides specified scan locations to the LIDAR unit. The camera is configured to capture an image with an adjusted focus based on depth information, obtained by the LIDAR unit, associated with the detected object.

摘要： Techniques and systems are provided for generating one or more depth maps. For example, a process can include transmitting a pattern of light using a structured light source, the pattern of light including at least a first sub-pattern group of a primitive pattern and a second sub-pattern group of the primitive pattern. The process can include generating an overlapped pattern of light, the overlapped pattern of light including at least the first sub-pattern group of the primitive pattern overlapped with the second sub-pattern group of the primitive pattern. The process can include receiving one or more return signals based on the overlapped pattern of light. The process can include generating a depth map based on the one or more return signals.

摘要： A method and electronic device for selectively obtaining depth information at locations within a scene are described. Image content analysis is performed on a received image of the scene. Locations within the image to obtain depth information within the scene are determined based on the image analysis. The locations are provided to a LIDAR (light+radar) unit to selectively obtain depth information at the scene locations. The depth information is received from the LIDAR unit and a second image analysis is performed on a second image. The second image analysis is based on the image content of the second image and the received depth information. Updated locations based on the second image analysis may be provided to the LIDAR unit to obtain updated depth information.

摘要： Aspects disclosed herein relate to aggregating functionality of computer machine instructions to generate additional computer machine instructions and including the additional computer machine instructions in an instruction set architecture (ISA). An exemplary method includes selecting at least first and second computer machine instructions from an instruction set, aggregating functionality of the first and second computer machine instructions to generate a third computer machine instruction, and adding the third computer machine instruction to the instruction set.
