We’re sometimes asked about how to capture motion and record 4D videos using Artec scanners. This article describes the process in more detail.
- Artec Studio has a dedicated mode called Fast capture that allows the scanner or sensor to capture “unaligned” 3D frames that contain the moving object.
- You can use one Artec scanner (or third-party 3D sensor) for motion capture, or combine several scanners/sensors in a bundle.
- To scan using one device, set “1” for Number of scanners to use in the Multi section. To record using multiple scanners, select the Use bundle option.
- You can set the duration (in seconds) of the scanning session in Multi before you start.
- Alternatively, just stop the process manually by pressing the appropriate button on the Artec scanner or the Stop button in Artec Studio.
- By default, every 3D frame recorded in Fast capture mode is polygonal; it contains texture information as well.
Playing a 4D video in Artec Studio
- Select your raw scan in the Workspace panel and hit Ctrl+P to play the sequence of 3D frames you recorded during this scan.
- Alternatively, you can double-click on the scan in the Workspace and click the Play button near the top of the window.
- Set the playback speed in File - Settings - UI - Playing; the default value is 15 FPS.
- Switch between Solid, Wireframe and Points to adjust the display mode:
Exporting a sequence of 3D frames
- Select your raw scan(s) in the Workspace and choose File - Export scans....
- Choose ply, stl, obj or wrl as the 3D-output extension and jpg, bmp or png as the texture-output extension.
- Artec Studio will save a sequence of 3D frames in a specified folder.
- Continue post-processing the data using a third-party software package of your choice.
Here is a video that should give you a rough idea of the workflow and how these 3D frames are used:
More or less the same principle with recording a sequence of 3D frames was used in this Linkin Park video (check starting from 01:12):
The setup with the Artec3D scanner is shown on the picture below:
Note: the capture devices in this video are Artec MHT scanners; they’re the precursor of Artec Eva.
