Embodiment 1

[0055] Initially scan the scanned object placed on the turntable to obtain the scanned model of the scanned object, obtain the watertight model of the scanned object according to the scanned model, determine the geometric center of the watertight model, and determine the location of the scanned object with the geometric center of the watertight model as the spherical center. The first scanning sphere at each first predetermined position determines the second predetermined position of the scanner on each scanning sphere according to the scanning sphere and the scanning plane of the scanner, and each second predetermined position has a corresponding first predetermined position of the scanned object, Determine the amount of data missing in the above-mentioned scanning model when the scanner scans at each second predetermined position, and determine the second predetermined position with the largest missing amount as the second position, and determine the first predetermined positi...

Embodiment 2

[0057] Initially scan the scanned object placed on the turntable, obtain the scanned model of the scanned object, obtain the watertight model of the scanned object according to the scanned model, determine the geometric center of the watertight model, and use the projection point of the geometric center of the scanned object on the central axis of the turntable Determine the second scanning sphere for the center of the sphere and determine the offset distance of the geometric center of the scanned object relative to the central axis of the turntable, and determine the second predetermined position of the scanner according to the second scanning sphere, the scanning plane of the scanner and the offset distance. The two predetermined positions have corresponding first predetermined positions of the object to be scanned, determine the amount of missing data in the above-mentioned scanning model when the scanner scans at each second predetermined position, and determine the second p...

Embodiment 3

[0059] Initially scan the scanned object placed on the turntable to obtain the scanned model of the scanned object, obtain the watertight model of the scanned object according to the scanned model, determine the geometric center of the watertight model, and determine the location of the scanned object with the geometric center of the watertight model as the spherical center. The first scanning sphere at each first predetermined position determines the second predetermined position of the scanner on each scanning sphere according to the scanning sphere and the first scanning plane of the scanner, and each second predetermined position has a corresponding first predetermined position of the scanned object. position, the turntable moves to each first predetermined position, the scanner moves to the corresponding second predetermined position for scanning, updates the scanning model of the scanned object, and obtains a complete three-dimensional model of the scanned object.

Abstract

The invention provides a scanning control method and device, a system, a storage medium and a processor. The control method comprises the following steps that a scanner is controlled to conduct preliminary scanning on a scanned object according to a preset path, and a scanning model of the scanned object is obtained; a second preset position of the scanner corresponding to the scanned object at each first preset position is determined according to the scanning model; and the scanner is controlled to scan the scanned object located at the corresponding first preset position at least partially at the second preset position until a three-dimensional model is obtained. According to the control method, the scanning position of the scanner is determined according to the scanning model obtained through the preliminary scanning and the position of the scanned object, part of the scanning position is selected for the scanning, intersection and repetition of the scanning range are avoided, the number of scanning times is reduced, and therefore the process of scanning the three-dimensional model is simpler compared with the prior art.

Description

technical field [0001] The present application relates to the field of three-dimensional printing, in particular, to a scanning control method, device, system, storage medium and processor. Background technique [0002] In the process of 3D printing, it is generally necessary for the robot arm to control the scanner to move according to a predetermined trajectory to obtain data by scanning the real model of the object, and then the printer performs 3D printing according to the data. [0003] In the prior art, it is necessary to obtain the second predetermined position of the mechanical arm first, and the second predetermined position is very complicated, so the obtaining process is also relatively complicated. [0004] The above information disclosed in the Background section is only to enhance the understanding of the background of the technology described herein, therefore, the Background may contain certain information which is not formed in the country for those skilled ...
