The utility model discloses also relate to a 3D scanning system and a 3D print system. The utility model provides a 3D scans the subassembly, and the mode that adopts projection light emission module and vision positioning module to combine has realized drawing and founing of the horizontal information of article, has improved the concertedness that scans and print, reaches the effect that scans with printing synchronization.
Description
Technical field
The utility model relates to 3D and prints field, more particularly, relates to a kind of 3D scan components, scanning system and 3D print system.
Background technology
The 3D scanning that current use is comparatively ripe and 3D printing technique, can realize the 3D reproduction process to article, below just this process be divided into 3D scanning and 3D to print two background technologies elaborations:
3D scans:
Traditional 3D scanning process is divided into acquisition depth map and modeling two parts.
Obtain depth map:
According to the characteristic of binocular telemetry, expect the complete cross-section figure of article 360 °, scanned product must be made to rotate a circle, after the comprehensive range finding of camera, just can obtain complete cross section, otherwise cannot will start to set up complete 3D model due to the incompleteness of certain a part of scan-data.
Modeling:
The foundation of 3D model relies on the depth information of 3D modeling software process illuminant module acquisition, use specific algorithm to calculate and obtain the digital model of article, because the operand of modeling process is large, algorithm is complicated, thus require very high to the technical difficulty of modeling software, also cause the dependence that modeling process is stronger to modeling software.
3D prints:
The principle of work of tradition 3D printer, after being that 3D model complete for article is divided into the cross section of certain precision, then is converted to the data layout that printer can identify, and then controls the stepper motor in different coordinate axis, realize melting and the spraying of material.The ultimate principle that 3D prints is that cross section prints, and by successively increasing material, realizes the integer be shaped.
To sum up, the working method of " line laser vertical sweep, successively prints xsect " that the 3D reproduction process that prior art can realize adopts, and the workflow of " entire scan → entirety prints ", realize copying the 3D of article.
The technical matters that above scheme exists:
Use the 3D reproducing unit that current 3D scans and 3D printing technique realizes, have following a few point defect:
1. after 3D scanner must wait for article rotating one week (or some scanner around article one week), just can obtain the depth information in a cross section, if not, then cannot obtain the complete cross-section of 360 °, cause that the scanning process needed for article entirety increases, scan efficiency is low.
2. strong to the dependence of 3D modeling software, the cloud computing technology center of computing machine or internet must be relied on to complete the overall process of computing to 3D modeling, and the encapsulation degree of 3D soft modeling technique is large, operation easier is higher, user is difficult to complete according to self-demand and wish revise the personalization of original model bank, operability and replicability poor.
3. 3D printer must wait for that terminating rear just can beginning to the scanning process of article full-height prints cross section, complete and copy, be separated completely with 3D scanning process, a kind of like this process of scanning → printing is serial processing but not the clone method of process of running simultaneously, not only cause low, the synchronous situation experiencing difference of concertedness, also raised the time cost of work, duplicating efficiency is fallen sharply.
4. 3D printer not only needs the scanning process waiting for article, also must process the 3D model of article entirety, so that user cannot freely realize the choice of an article part and splicing according to wish easily, not only reduce the dirigibility that 3D prints, also cause the waste of calculation resources to a certain extent.
