摘要： A method of calibrating a LiDAR sensor mounted on a vehicle includes storing a reference three-dimensional image acquired by the LiDAR sensor while the LiDAR sensor is in an expected alignment with respect to the vehicle. The reference three-dimensional image includes a first image of a fixed feature on the vehicle. The method further includes, acquiring, using the LiDAR sensor, a three-dimensional image including a second image of the fixed feature, and determining a deviation from the expected alignment of the LiDAR sensor with respect to the vehicle by comparing the second image of the fixed feature in the three-dimensional image to the first image of the fixed feature in the reference three-dimensional image.

摘要： A system and method include scanning a light detection and ranging (LIDAR) device through a range of orientations corresponding to a scanning zone while emitting light pulses from the LIDAR device. The method also includes receiving returning light pulses corresponding to the light pulses emitted from the LIDAR device and determining initial point cloud data based on time delays between emitting the light pulses and receiving the corresponding returning light pulses and the orientations of the LIDAR device. The initial point cloud data has an initial angular resolution. The method includes identifying, based on the initial point cloud data, a reflective feature in the scanning zone and determining an enhancement region and an enhanced angular resolution for a subsequent scan to provide a higher spatial resolution in at least a portion of subsequent point cloud data from the subsequent scan corresponding to the reflective feature.

摘要： The light source device includes a light emitting unit, a scanning unit, and a controller. In the light emitting unit, a plurality of light emitting elements is arranged along a first direction. The scanning unit scans light emitted from the plurality of light emitting elements along the second direction orthogonal to the first direction. The controller performs control to make the number of times of light emission of the first light emitting element group included in the plurality of light emitting elements larger than the number of times of light emission of the second light emitting element group not included in the first light emitting element group.

摘要： A vehicle upper structure includes a roof member of a vehicle, a sensor, a sensor cover, and an external cover. The sensor is mounted on an upper part of the vehicle such that at least part of the sensor is located above the roof member. The sensor is configured to emit and receive electromagnetic waves to recognize the external environment of the vehicle. The sensor cover covers at least the part of the sensor that is above the roof member. The external cover covers the sensor cover from outside with a gap between the external cover and the sensor cover.
