    Abstract: A data acquisition apparatus and method for determining a pose thereof. The disclosed data acquisition apparatus includes a mounting component and the sensor fixed to the mounting component. The sensor is oriented at a preset pose relative to the ground and configured to scan the surrounding environment of the data acquisition apparatus at a scanning frequency as a vehicle moves on the ground to obtain a sequence of point cloud data frames. The pose allows a coverage of an effective field of view of the sensor on the ground to be continuous across temporally neighboring frames in the sequence of point cloud data frames.

    Abstract: The present disclosure relates to autonomous vehicle technology, and provides a method and an apparatus for trailer angle measurement, as well as a vehicle. With the present disclosure, it can be determined whether to use a single-beam lidar or a multiple-beam lidar for trailer angle measurement based on an initial trailer angle. When it is determined to use the multiple-beam lidar a deflection direction of the semi-trailer can be obtained, and laser light emitted by the multiple-beam lidar on a side of the deflection direction and reflected by a trailer surface can be collected. A coordinate transformation and selection process can be applied on the laser point cloud to form a candidate point cloud. A boundary straight line of the trailer can be determined by means of optimized solution of the candidate point cloud. A trailer angle can be determined based on the boundary straight line of the trailer.
