Page 26 The software (SW) includes several modules. Calibry Tray Manager. This module is designed to provide the scanning pro- cess and to acquire raw data. Calibry Nest. This module is designed for raw data postprocessing and sav- ing of the obtained 3D model in a conventional format.
Page 27: System Requirements
If there is more than one graphics card in your computer (e.g., both In- tel and NVIDIA) make sure that Calibry software always uses the more high-performance graphics card by default. We do not recommend that you use screens with 4K resolution.
Page 28 Microsoft web site and installing it yourself: https://www.microsoft.com/en-us/download/details.aspx?id=48145 On successful startup, the Calibry Nest window will open, and in the notifi- cation area in the right-bottom corner the Calibry Tray Manager icon will appear.
Page 29 Each Calibry scanner is supplied with a calibration file containing its individ- ual settings. If necessary, a calibration file can be requested from distributor. To interact with the scanner its calibration file should be loaded to Calibry Nest. If you plan to connect several scanners to one computer then calibra- tion files should be loaded for each one of them.

Page 32 Software manual Calibry SW – Postprocessing Raw Data Raw data from scanning represents a set of frames captured by the scanner and used for 3D model building. Most of the frames are geometrical. Each geometric frame contains a certain number of points on the surface of the object being scanned.
Page 33 3D scanner Apart from frames, raw data contain several files with additional information. The data set described above is written into a file with .ascan extension, also called a project file. Opening a Project File To begin working with a project you should open it using one of the following methods: 1.
Page 34 Software manual Data Visualization A visualization window is used to view scanned data and the results of its pro- cessing. When working with data, a user can view: • A cloud of points formed by one frame. Select the required geometric frame in the project tree;...
Page 35 3D scanner Simple Postprocessing Simple postprocessing is the name for data postprocessing when only one pro- ject file is used for 3D model creation. This means that to obtain the model only one scanning session was launched, i.e., the entire object has been scanned once as a whole.
Page 36 Software manual After registration At the registration stage, a preliminary cleaning procedure can be executed by specifying the corresponding setting. This procedure will automatically re- move those points from the cloud that will be determined by the algorithm as noise or other data not relevant to the object being scanned. After preliminary cleaning...
Page 37 3D scanner Finalization At the finalization stage, the cloud of points is converted into a polygonal model. In this case, it is necessary to specify certain algorithm settings. In the top of the window you can select an array of preset settings de- pending on the scanner model and the scanned object.
Page 38 Software manual The result of running the algorithm with a low resolution (4 mm) The result of running the algorithm with a high resolution (0.7 mm)
Page 39 3D scanner Fill holes. On the obtained surface of the 3D model, holes can appear. If the real object being scanned actually has holes on its surface, this is normal. But sometimes the holes are formed as a result of insufficient raw data. In this case the situation can be corrected algorithmically at the finalization stage.
Page 40 Software manual Sharpness. This parameter determines the appearance of the polygon mesh. At a low level of sharpness, the polygons are merged more smoothly, without sharp angles, while high sharpness makes geometry more detailed and thus the image becomes more clear.
Page 41 This parameter can vary depending on the model of your scanner, as well as on marker type: markers can be both magnetic and printed by you on the printer. Markers are not removed on the texture Calibry DRAKE Maxi DRAKE Midi DRAKE Mini...
Page 42 Cut height is counted from the floor and is specified according to how the model has been scanned. When the Thor3D rotary table is used the parameter of 150 mm should be set, when scanning is executed without this table the value of 5 mm should be set.
Page 43 Texture mapping Calibry scanners are equipped with a color camera which allows you to take images of three-dimensional surfaces with texture. Texturizing is performed by projecting separate captured color frames onto a finished 3D model. The Texture size can be specified manually by choosing one of three provided op- tions: 1024 ×...
Page 44 2.5. Simplification [Percent of initial model / Number of triangles in new model] Texture mapping [Texture size] When any postprocessing procedures are executed, the Calibry SW can- not execute other operations. Scanning, opening and processing other projects, etc. are impossible. Wait for completion of the current post- processing procedure in order to proceed with new operations.
Page 45 3D scanner Multiple Postprocessing To build 3D models of certain objects, it is sometimes necessary to execute several scanning sessions. Most frequently, this is necessary to scan an object from all directions. E.g., scanning an object from above and then turning it over and to scan from below.
Page 46 Software manual Automatic alignment For simplicity, at first let’s consider the procedure of automatic alignment an object of three parts by markers. In the project window, highlight the 3D models of all components to be aligned and click Alignment by points. The alignment window will appear. The working alignment window is divided into three parts: 1.
Page 47 3D scanner Eventually, the resulting model consisting of parts #1 and #2 will be displayed in the basic window, just like in the result window. We need to «stick» the remaining third part to this model. To do this, left-click it in the scan list window (Meshes for alignment).
Page 48 Software manual Click Add Aligned to Base once more. The other parts of the object can be added to the base model in a similar way until all of them «stick» to the base. When all parts are aligned together click Accept Changes. The complete point cloud of an aligned model will be displayed on the screen.
Page 49 3D scanner Everything is ready for starting up multiple registration and multiple finaliza- tion procedures. The intent of these procedures, as well as settings applied are similar to the relevant procedures for simple postprocessing. The difference is only in that for their execution the data obtained in several scanning sessions is used together.
Page 50 Software manual To place an alignment point, double-left-click it first on the base and then on the second model. Specify a minimum of three alignment points. Double-click a point to remove it. Press and hold CTRL key and move a point to relocate it.
Page 51 3D scanner In the context of our example, let’s begin to highlight frames starting from the very first. Having added more than 4000 frames to selection we see that divergencies in leg geometry are still not present. Now let’s begin to review frames from bottom to top starting from the last. From a certain moment (approximately from Frame #4050) the leg starts to split.
Page 52 Software manual Deleting Bad Frames In the context of the relevant example, it can be noted that the 3D model is obtained even without the last group of frames which cause the splitting of the leg. Therefore, all the frames starting from #4051 onward can simply be deleted.
Page 53 3D scanner In the context of the relevant example, you can try not to delete frames ##4051–4455 as bad frames, but simply “erase” the leg image on them by deleting the corresponding points from the cloud. 3D Model Processing Left-click the 3D model resulting from postprocessing. To the right of the pro- jects, the toolbar will be displayed.
Page 54 Software manual Cut on Frames. When the button is pressed all selected areas of model sur- face are deleted not only from the model itself but also from corresponding frames. Fill selected holes. When the button is pressed the list of all holes detected by the algorithm on the 3D model surface is displayed in the project tree.
