Abstract: The present invention relates to a turntable mechanism, including a flat plate and a rotating device for driving the flat plate to rotate, where the flat plate rotates to generate a negative pressure between a lower surface of the flat plate and a surface of an adsorbed object, the flat plate and the adsorbed object adhere together by an adsorption force generated by the negative pressure, and in this case, a gap is kept between the lower surface of the flat plate and the surface of the adsorbed object. In the present invention, a continuous, consistent, and stable fluid film is formed between the turntable and the adsorbed object, and a secondary flow is not easily generated, thereby ensuring that the adsorption force between the rotating flat plate and the adsorbed object is more stable.

Abstract: A full-automatic classification method for a three-dimensional point cloud, including: acquiring a three-dimensional point cloud dataset; performing down-sampling on a three-dimensional point cloud represented by the three-dimensional point cloud dataset, selecting some points in the three-dimensional point cloud as sampling points, constructing a point cloud area group based on each sampling point, extracting a global feature of each point cloud area group, and replacing the point cloud area group where the sampling point is located with the sampling point; performing up-sampling on the three-dimensional point cloud, and performing splicing fusion on the global features of the point cloud area group where each point in the three-dimensional point cloud is located; performing category discrimination on each point in the three-dimensional point cloud; performing statistics on the number of points contained in each category, and selecting the category with the largest number of points as the category of the thr
