Abstract

The invention provides an image acquisition and processing method and device for three-dimensional scanning and three-dimensional scanning equipment. The three-dimensional scanning image processing method comprises the following steps: synchronously acquiring a projection pattern of first wavelength light and an illumination image of second wavelength light projected on a measured object, and acquiring a color texture image of the measured object. Through the method and the device, the problem of texture dislocation caused by time difference and position difference between the three-dimensional reconstruction data and the color texture map in the prior art is solved, so that the effects of high accuracy, low production cost and low time consumption of the texture map are achieved.

Description

Technical field [0001] The present invention relates to the field of communications, in particular to a three-dimensional scanning image acquisition and processing method, device and three-dimensional scanning equipment. Background technique [0002] At present, there are many dynamic 3D scanners on the market, which can perform real-time 3D scanning to obtain the 3D topography of the surface of the object. If the texture of the object itself is pasted on the 3D data surface, the display effect will be improved. Therefore, it is necessary to scan the current view of the 3D data. Time to get the texture picture of the current perspective to map in real time. The structured light triangulation principle, which is mostly used by dynamic 3D scanners, requires that structured light patterns be projected on the surface of the object for 3D reconstruction. Figure one Generally, the acquisition is performed at the previous moment and position or the next moment and position of the recons...
