  • Patent number: 10718857
    Abstract: A LIDAR system emits laser pulses, wherein each pulse is associated with a power level. A laser emitter is adjusted during operation of a LIDAR system using power profile data associated with the laser. The power profile data is obtained during a calibration procedure and includes information that associates charge duration for a laser power supply with the actual power output by laser. The power profiles can be used during operation of the LIDAR system. A laser pulse can be emitted, the reflected light from the pulse received and analyzed, and the power of the next pulse can be adjusted based on a lookup within the power profile for the laser. For instance, if the power returned from a pulse is too high (e.g., above some specified threshold), the power of the next pulse is reduced to a specific value based on the power profile.

    Abstract: An HD map system represents landmarks on a high definition map for autonomous vehicle navigation, including describing spatial location of lanes of a road and semantic information about each lane, and along with traffic signs and landmarks. The system generates lane lines designating lanes of roads based on, for example, mapping of camera image pixels with high probability of being on lane lines into a three-dimensional space, and locating/connecting center lines of the lane lines. The system builds a large connected network of lane elements and their connections as a lane element graph. The system also represents traffic signs based on camera images and detection and ranging sensor depth maps. These landmarks are used in building a high definition map that allows autonomous vehicles to safely navigate through their environments.

  • Patent number: 10663586
    Abstract: Embodiments describe optical imagers that include one or more micro-optic components. Some imagers can be passive imagers that include a light detection system for receiving ambient light from a field. Some imagers can be active imagers that include a light emission system in addition to the light detection system. The light emission system can be configured to emit light into the field such that emitted light is reflected off surfaces of an object in the field and received by the light detection system. In some embodiments, the light detection system and/or the light emission system includes micro-optic components for improving operational performance.

  • Patent number: 10656275
    Abstract: Aspects of the present disclosure involve example systems and methods for remote sensing of objects. In one example, a system includes a light source, a camera, a light radar (lidar) system, a region of interest identification circuit, and a range refining circuit. The region of interest identification circuit identifies a region of interest corresponding to an object and a first range of distance to the region of interest using the camera and the light source. The range refining circuit probes the region of interest to refine the first range to a second range of distance to the region of interest using the lidar system, the second range having a lower uncertainty than the first range.

  • Patent number: 10650342
    Abstract: A user requests a package delivery from a package delivery system. The package delivery system provides the user with a machine-readable code for display at the delivery location. An aerial delivery device receives, from the package delivery system computing device, information associated with the delivery location of the package. The information comprises information matching the information in the machine-readable code associated with the delivery location and a delivery address. The delivery device secures the package for transporting to the delivery location and transports the package to the delivery address. The delivery device locates the machine-readable code on a display at the delivery address and verifies that the information from the machine-readable code is associated with the package. The delivery device deposits the package on the display.

  • Patent number: 10641870
    Abstract: A LIDAR system and a method for operating a LIDAR system are disclosed. The LIDAR system broadly includes a transmitter that that emits a light pulse in response to a launch signal, a receiver that detects light pulses and determines a time of arrival for each detected light pulse; and a controller that generates an ordered sequence of frames. The controller generates a launch signal at the start of each frame and records information specifying a time of arrival relative to the start time for all light pulses received by the receiver until a stop time. After the stop time, the controller waits for the interframe delay time before generating another launch signal. The interframe delay time is different for each frame in the sequence of frames. The controller determines a distance between the transmitter and an object from the recorded information.

  • Patent number: 10634790
    Abstract: An optical imaging system and method for use in a degraded visual environment is provided. A wideband modulated laser pulse is transmitted from a first location through a medium toward a target object. An input of the transmitted wideband modulated laser pulse is detected by an optical receiver. A target modulated laser pulse, reflected from the target object is detected by the optical receiver. The transmitted and reflected laser pulses are filtered by a bandpass filter, based on a predetermined modulated frequency range. The filtered transmitted and reflected laser pulses are digitized by an analog-digital converter. The digitized transmitted laser pulse is correlated with digitized reflected laser pulse by a digital matched filter, wherein the matched filter produces a passband matched filter output. A range of the target object is determined based on the matched filter output.
