Abstract

The invention discloses a quick sectioning method based on point cloud, an intelligent terminal and a cloud platform, and the method comprises the following steps: uploading point cloud data, so as toenable the cloud platform to convert the point cloud data into an octree binary system for storage, and obtaining a point cloud file; after a viewing instruction is obtained, asynchronously loading the point cloud file from the cloud platform according to the viewing instruction, and visually rendering the point cloud according to the point cloud file; sensing the area of interest and the parameters, so that the cloud platform evaluates the number of point clouds in the region of interest and returns points; uploading a generation instruction to enable the cloud platform to calculate the number of point clouds in the area of interest to obtain target data; and uploading the downloading instruction, so that the cloud platform converts the target data into a corresponding output data type and returns the output data type. Based on a browser, a PC terminal, a mobile terminal and other clients are supported, the cloud platform stores the point cloud data and performs data operation, the hardware requirements of the clients are reduced, and the invention can be widely applied to the field of three-dimensional visualization.

Description

technical field [0001] The invention relates to the technical fields of three-dimensional visualization, three-dimensional reverse engineering, engineering drawing and digital construction, and in particular to a point cloud-based fast sectioning method, an intelligent terminal and a cloud platform. Background technique [0002] Cloud point data means that the scanned data is recorded in the form of points, each point contains three-dimensional coordinates, and some may contain color information. Due to the large data volume of point cloud data, a large storage space is required, and a large network bandwidth, hard disk, memory, etc. are required for transmission, and there is no good management of large data set point clouds, so it is not easy to share. Users need to extract interested digital asset information in large scenarios. In addition, the data processing of point cloud data may have multiple data conversion formats and data redundancy. At present, the display and ...
