Problems solved by technology

[0004] The above scheme of using the PCL point cloud library to perform noise reduction processing on all the collected point cloud data to obtain the point cloud data of obstacles, each iteration process will traverse all the point cloud data, and the multiple iteration processing process will make the entire point cloud data Cloud processing takes too long
In addition, directly using the PCL library to detect obstacles is prone to missed and false detections

Abstract

The invention discloses a point cloud processing method and device and a computer readable storage medium. Specifically, the target area of the obtained first point cloud data is segmented through atleast two segmentation surfaces to obtain second point cloud data, then the second point cloud data is projected to a preset projection plane according to a preset direction to obtain third point cloud data, and finally, the third point cloud data is denoised through a plurality of segmentation lines to obtain fourth point cloud data. According to the scheme provided by the embodiment of the invention, when the three-dimensional point cloud data is processed, most of the noise point data can be quickly removed, so that the processing effect of the noise point data is improved.

Description

technical field [0001] The present application relates to the technical field of data processing, in particular, to a point cloud processing method, device, and computer-readable storage medium. Background technique [0002] The point cloud data contains the spatial position information of the collected points, therefore, the point cloud data can be used for parking obstacle judgment and target detection. There are often some noise data in the point cloud data obtained by measuring instruments. In the calculation process of point cloud data, there will also be errors, so that the point cloud data and the actual position of the object cannot be completely consistent. [0003] In the prior art, in the process of processing point cloud data, a PCL (English name PointCloud Library, abbreviated as PCL) point cloud library is often used for filtering processing. In the process of using PCL point cloud library for filtering processing, it is necessary to repeatedly call the SDK (...
