Abstract: An electronic device is described. The electronic device includes a camera configured to capture an image of a scene. The electronic device also includes an image segmentation mapper configured to perform segmentation of the image based on image content to generate a plurality of image segments, each of the plurality of image segments associated with spatial coordinates indicative of a location of each segment in the scene. The electronic device further includes a memory configured to store the image and the spatial coordinates. The electronic device additionally includes a LIDAR (light+radar) unit, the LIDAR unit steerable to selectively obtain depth values corresponding to at least a subset of the spatial coordinates. The electronic device further includes a depth mapper configured to generate a depth map of the scene based on the depth values and the spatial coordinates.

Abstract: Solid-state electronic light detection and ranging (LIDAR) is disclosed. In one aspect, an electronic device for use in a LIDAR system is provided. The electronic device includes a plurality of electrically controllable light-direction-changing elements. The electronic device is configured to receive, from a laser, a beam of light. The electronic device also receives, from a controller, a series of signals that control the electrically controllable light-direction-changing elements to generate a successive series of different diffraction grating patterns configured to move at least one intensity maxima to a corresponding successive series of locations across a field of view (FOV).

Abstract: Methods and apparatus for providing dynamically adjusted radiated signals are disclosed. In one aspect, a method of detecting one or more objects in a path of travel of a vehicle may include generating a laser with radiated power. The method may further include emitting the laser in a direction of travel of the vehicle and receiving one or more reflections of the emitted laser reflected from the one or more objects located in the direction of travel of the vehicle. The method may also further include generating a signal indicating that the one or more objects are in a path of the vehicle based on the received one or more reflections. The method may also include dynamically adjusting the radiated power of the laser based on an input corresponding to one or more of (i) a current speed of the vehicle or (ii) a current position of the vehicle.

Abstract: Disclosed herein are techniques for light beam scanning in a light detection and ranging (LIDAR) system. The LIDAR system includes a beam shaping subsystem configured to generate an illumination pattern elongated in a first direction, and a scanning subsystem configured to direct the elongated illumination pattern towards a plurality of positions along a second direction different from the first direction. The LIDAR system further includes a sensor configured to generate a detection signal in response to detecting light reflected by a target object illuminated by the elongated illumination pattern, and a processor configured to determine a characteristic of the target object based on the detection signal.
