    摘要： A method for detecting objects using a LIDAR system may include controlling a light emission assembly comprising a light source in a manner enabling spatial light modulation to a field of view (FOV) of the LIDAR system to vary during different flash light emissions of the light emission assembly. The method may also include controlling a sensor to detect first reflection signals indicative of reflections of first flash light emissions from objects in the FOV. The method may further include determining a nonuniform spatial light modulation for the light emission assembly based on at least one of the first reflection signals. The method may also include instructing the light emission assembly to emit to the FOV a second flash light emission in accordance with the nonuniform spatial light modulation, and detecting an object in the FOV based on second reflection signals of the second flash light emission.

    摘要： A pulsed laser diode driver may include at least one low side switching circuit connected to at least one laser diode. The at least one laser diode may generate at least one light pulse. The low side switching circuit may include an input for receiving energy. The low side switching circuit may also include an inductor configured to store at least a portion of the received energy. Further, the low side switching circuit may include a trigger switch. The trigger switch may cause the inductor to store the portion of the received energy when the trigger switch is closed, and the trigger switch may cause the portion of the received energy stored in the inductor to be delivered to the at least one laser diode after the trigger switch is opened.

    摘要： Systems and methods may detect an object within a minimum predetermined distance of a LIDAR system. The LIDAR system may comprise a processor configured to control a light source and a light deflector to illuminate objects located in a space illuminated by the light source; determine a distance to a first object based located within a field of view of a LIDAR sensor; receive, from a supplementary sensor, reflection signals indicative of light reflected from a second object outside the field of view; determine, based on the second reflection signals that the second object is located within a predetermined distance; and regulate, based on the determination, at least one of the light source and the light deflector to prevent an accumulated energy density of light emitted by the light source from exceeding a maximum permissible exposure level.

    摘要： A vehicle-assistance system for classifying objects in a vehicle's surroundings is provided. The system may include at least one memory configured to store classification information for classifying a plurality of objects and at least one processor configured to receive, on a pixel-by-pixel basis, a plurality of measurements associated with LIDAR detection results. The measurements may include at least one of: a presence indication, a surface angle, object surface physical composition, and a reflectivity level. The at least one processor may also be configured to receive, on the pixel-by-pixel basis, at least one confidence level associated with each received measurement, and access the classification information. The at least one processor may further be configured to, based on the classification information and the received measurements with the at least one associated confidence level plurality, identify a of pixels as being associated with a particular object.

    摘要： A LIDAR system is provided. The LIDAR system comprises at least one processor configured to: control at least one light source in a manner enabling light flux of at least one light source to vary over a plurality of scans of a field of view, the field of view including a near-field portion and a far-field portion; control at least one light deflector to deflect light from the at least one light source in a manner scanning the field of view; implement a first scanning rate for first frames associated with scanning cycles that cover the near-field portion and a second scanning rate for second frames associated with scanning cycles that cover the far-field portion; and control the at least one light source to alter a light source parameter and thereby project light in a manner enabling detection of objects in the second frames associated with the far-field portion.
