摘要： Perception sensors of a vehicle can be used for various operating functions of the vehicle. A computing device may receive sensor data from the perception sensors, and may calibrate the perception sensors using the sensor data, to enable effective operation of the vehicle. To calibrate the sensors, the computing device may project the sensor data into a voxel space, and determine a voxel score comprising an occupancy score and a residual value for each voxel. The computing device may then adjust an estimated position and/or orientation of the sensors, and associated sensor data, from at least one perception sensor to minimize the voxel score. The computing device may calibrate the sensor using the adjustments corresponding to the minimized voxel score. Additionally, the computing device may be configured to calculate an error in a position associated with the vehicle by calibrating data corresponding to a same point captured at different times.

摘要： Apparatus and associated methods relate to detecting jams when an intensity of a reflected signal exceeds a predetermined intensity threshold and an intensity window metric based on historic intensity value(s) fails to exceed an intensity window threshold for more than a predetermined time threshold. In an illustrative example, a jam detection unit (JDU) may emit a signal and detect a reflection of the signal. The JDU may, for example, compare intensity of the reflected signal to the intensity threshold. The JDU, for example, may compare the intensity threshold with at least one historic intensity value to determine the intensity window metric. If the intensity value exceeds the intensity threshold and the intensity window metric has not exceeded the intensity window threshold for longer than the time threshold, then the JDU may, for example, generate a jam signal. Various embodiments may advantageously detect jams based on intensity of a reflected signal.

摘要： A LiDAR system and method of detecting objects using same includes a plurality of coaxially arranged LiDAR transmitters and detectors. A movable optical element redirects optical signals between the LiDAR transmitters and an external region and reference optical element. The detectors receive returning optical signals after they have deflected off objects in the surrounding environment to generate an electrical signal. A reference signal is generated from the optical signals directed towards the reference optical element. The system determines the position of an object in the external region by adjusting the electrical signal using the reference signal.

摘要： A measurement of the rotation speed of an object is made using a time-of-flight sensor configured to detect a passing of one or more of elements of the object through a given position. The time-of-flight sensor is further mounted on a one-person vehicle configured to protect the one-person vehicle against collisions through the making a time-of-flight measurement of a relative speed between the one-person vehicle and an obstacle.

摘要： In some embodiments, a LIDAR system may include at least one processor configured to control at least one light source for projecting light toward a field of view and receive from at least one first sensor first signals associated with light projected by the at least one light source and reflected from an object in the field of view, wherein the light impinging on the at least one first sensor is in a form of a light spot having an outer boundary. The processor may further be configured to receive from at least one second sensor second signals associated with light noise, wherein the at least one second sensor is located outside the outer boundary; determine, based on the second signals received from the at least one second sensor, an indicator of a magnitude of the light noise; and determine, based on the indicator the first signals received from the at least one first sensor and, a distance to the object.

摘要： Techniques are described for compensating for movements of sensors. A method includes receiving two sets of sensor data from two sets of sensors, where a first set of sensors are located on a roof of a cab of a semi-trailer truck and a second set of sensor data are located on a hood of the semi-trailer truck. The method also receives from a height sensor a measured value indicative of a height of the rear of a rear portion of the cab of the semi-trailer truck relative to a chassis of the semi-trailer truck, determines two correction values, one for each of the two sets of sensor data, and compensates for the movement of the two sets of sensors by generating two sets of compensated sensor data. The two sets of compensated sensor data are generated by adjusting the two sets of sensor data based on the two correction values.

摘要： A LIDAR system includes a LIDAR unit. The LIDAR unit includes a housing defining a cavity. The LIDAR unit further include a plurality of emitters disposed on a circuit board within the cavity. Each of the emitters emits a laser beam along a transmit path. The LIDAR system further includes a first optic rotatable about a first axis at a first rotational speed and a second optic rotatable about a second axis at a second rotational speed that is faster than the first rotational speed. The first optic is positioned relative to the LIDAR unit such that a plurality of laser beams exiting the LIDAR unit pass through the first optic. The second optic is positioned relative to the first optic such that each of a plurality of refracted laser beams exiting the prism disk reflect off of the second optic.
