Abstract

The invention provides a 3D scanning method and device, and the method comprises the steps: obtaining a first data frame when a rotary table is in a first state, recognizing a vacant space region corresponding to the rotary table according to the first data frame, increasing the height of the vacant space region, obtaining a working space region, acquiring a second data frame when the rotary table is in a second state, deleting data outside the coordinate range from the second data frame according to the coordinate range corresponding to the working space area to obtain a third data frame, and splicing the plurality of third data frames to obtain a second data frame when the rotary table is in the second state when the scanned object is placed on the rotary table; and obtaining a three-dimensional model corresponding to the scanned object. By identifying the vacant space area corresponding to the rotary table and deleting the interference data outside the vacant space area corresponding to the rotary table, the splicing error caused by the interference of useless data is reduced, so that the correct splicing of the scanning data in the scanning process of the rotary table is ensured, the splicing time is reduced, and the splicing accuracy is improved.

Description

technical field [0001] The present application relates to the technical field of 3D scanning, in particular to a 3D scanning method and device. Background technique [0002] The 3D scanner is divided into two working modes: rotary scan and hand scan. When the 3D scanner works in the rotary scan mode, the scanning mode is different from the hand-held scanning mode in that the scanner hardware itself is fixed above the tripod, and the scanned Objects are stably placed on the turntable tray. Since the turntable is placed on the reference table (such as the ground, workbench, etc.), and the scanning format is relatively large, during the scanning process, there will be a large amount of repeated table data other than the target scanned object in the data frame. Or the noise data around the turntable and other data that affect the real-time splicing effect are scanned, resulting in a large number of reference tabletops being repeatedly superimposed in each frame of the scanned da...
