Abstract: The embodiments of the present invention disclose a layering method and apparatus for point cloud data, a device, a medium and a vehicle, where the layering method includes: determining, for various frames of point cloud data corresponding to a to-be-processed trajectory, vehicle pitch angles relative to a horizontal plane in the case of a target vehicle collecting the various frames of point cloud data; dividing the to-be-processed trajectory into a ramp region and a non-ramp region according to a size relationship between the vehicle pitch angles corresponding to the various frames of point cloud data; and layering the non-ramp region according to height information. By using the above technical solution, the problem of dividing the point cloud data at different layers into the point cloud data in a same layer is solved; and the accuracy of a layering result of the point cloud data is improved.

Abstract: The present disclosure provides a novel wireless charging device, and belongs to the technical field of industrial endoscopes. The novel wireless charging device includes a base, an endoscope body, and a shell fixedly mounted at one end of the endoscope body; one side of an upper surface of the base is fixedly connected with a bracket; a top end of the bracket is fixedly connected with a U-shaped clamping seat; the endoscope body is clamped on an inner wall of the U-shaped clamping seat; and the other side of the upper surface of the base is fixedly connected with a charging seat.

Abstract: A lighting device with changeable beam angle and fixed center beam candle power. The device may include a light source, an electronic driver for driving the light source to emit light, a beam shaping element for shaping a beam of light emitted by the light source, a beam angle adjustment mechanism configured to change a positional relationship between the light source and the beam shaping element, and a sensor configured to provide a signal indicative of a setting of the beam angle adjustment mechanism. The electronic driver is configured to adjust the luminous flux emitted by the light source depending on the signal provided by the sensor. Such a lighting device may keep the center beam candle power of the emitted light constant when the beam angle is changed.

Abstract: A method and an apparatus for controlling an unmanned aerial vehicle (UAV) to land on a landing platform are provided. The method includes: receiving a landing preparatory signal instructing the UAV to enter into a landing preparatory state; monitoring the landing platform to generate a monitoring signal in response to the landing preparatory signal; and determining whether to control the UAV to enter into a landing mode based on the monitoring signal.
