Abstract: The present invention belongs to the technical field of oil field drilling, and relates to a ground testing device for a stabilized platform of a rotary steerable drilling tool. The ground testing device includes: a first supporting member and a second supporting member that are oppositely arranged, where the second supporting member is provided with a first mounting hole; a drill collar and a drill collar motor mounted outside the first supporting member, where a motor shaft of the drill collar motor penetrates the first supporting member and is connected to the drill collar, and a stabilized platform mounting assembly is arranged inside the drill collar; and a first vibration member connected to the drill collar and a second vibration member arranged in the first mounting hole in a sleeved manner, where an elastic member is arranged between the second vibration member and the second supporting member, and the elastic member is arranged on the second vibration member in a sleeving manner.

Abstract: A detection method (100) of a lidar (200), the lidar (200), and a system for a vehicle (300) including the same. The lidar (200) is capable of rotating around a rotating shaft, and includes an emitting unit (210) having a plurality of laser emitters (211). The detection method (100) includes: step S101, controlling the plurality of laser emitters (211) to emit laser beams for detection so that the lidar (200) has a non-uniform angular resolution along a horizontal direction; step S102, receiving echoes of the emitted laser beams for detection reflected by a target object and converting the echoes into electrical signals; and step S103, calculating a distance and/or reflectivity of the target object according to the electrical signals. Thereby, an angular resolution along a horizontal direction of the lidar (200) is flexibly configured, flight time and power consumption are reduced, and a detection range of the lidar (200) is improved.
