- The scanner only works when plugged in to a power supply so the first step is to connect the power cord to the power outlet located at the back of the scanner and make sure it is screwed tight. A better alternative for flexibility and increased mobility is to connect the battery pack instead of the scanner's original power cord (Note: these two cords are different and should not be interchanged). A blinking green light on the handle of the scanner should indicate that it is on.
- Insert the usb cable on the side of the scanner and connect it to the computer’s usb port.
- Open Artec Studio 14 on the laptop and ensure that the software detects the scanner.
- Keep the object to be scanned at a good distance from the scanner for best results.
The Artec 3D Scanner can be retrieved from the IT Support at the Syracuse SOA through appointments. The scanner comes with a laptop which has Artec Studio 14 pre-installed and a battery pack
How to scan with Artec Eva 3D Scanner
- Prepare the object and make sure it has enough geometry and texture details. Objects that are difficult to scan include objects with very dark surfaces, highly reflective or shiny objects, transparent objects like glass, some plastics, etc., objects with very thin edges e.g crumpled paper.
- Provide even lighting without using direct sunlight.
- Open Artec Studio 14, if you have connected the Artec Eva Scanner, the software will automatically select it.
- Create a new project before getting started: use the + button in the Workspace panel, select File – New Project from the menu, or use the shortcut Ctrl +N. Once you have saved the project, you will be able to load or unload scans as necessary and thereby limit RAM usage.
- Decide how many session you need in order to capture the entire object. By using a special third-party rotating table, you may be able to avoid interrupting the session and eliminate the need to turn the object by hand. Depending on your choice, you may
- Turn the object
- Position yourself to gain access to the other area.
- Use a rotating table.
- Click Preview or press play on the handle of the scanner. Direct your scanner at the object and practice your movements around the object, taking into account the proper Scanning Techniques.
- Identify the base plane for the mode by directing the scanner at the surface that supports the object and click Record to start capturing.
- Gradually move the scanner while monitoring the process in the 3D View Window.
- Capture what you can and pause or cease recording by clicking the Pause or Stop button, respectively. Choose Stop if you must make adjustments to the object’s positioning.
- Turn the object or otherwise adjust it as necessary, then capture any remaining unscanned regions.
Once you have successfully captured the object from all sides, click the Stop button on either the scanner handle or in Artec Studio.

- Pay closer attention to the object on the screen rather than looking at the actual object.
- Ensure that Artec Studio can accurately register frames from the scanner. To this end, do the following:
- Don’t move the scanner too fast
- Keep the object as close to the center of the field of view as possible
- Maintain the scanner orientation in such a way that the field of view is sufficiently filled with surfaces
- Try to position the scanner in the way the most surfaces in the field of view are colored in green which corresponds to the center of the range meter.
- If you’re capturing an object over several scans, remember to capture a common area in each one to ensure successful alignment.
- If you’re capturing an object in one scan, do so all the around the object – regardless of direction – plus a little more (360+ degrees)
- Avoid capturing any objects that may change shape during the scanning process. When the geometry of the scene is changing, the system may fail to find the correct position of new frames relative to previously aligned ones. If you have captured unwanted objects, you must remove them later during the editing stage.
- Don’t record too many frames: ensure that you have sufficiently scanned all regions, but avoid scanning them twice, except when providing overlapping areas for subsequent alignment.

- Models that have more solid fills and well defined geometry scan much better and faster. In the example below, the scan takes less than 3 minutes to produce the 3d product of the model on the left. The software tries to fill out the holes and gaps in the original model but overall produces a good quality 3d model.
- Models that have a lot of gaps and very small geometric details are much harder to scan and don't produce high quality results. In the example below, the model has a good number of gaps, reflective material and organic materials like the grass (all of which are very hard to scan) and thus the 3d scan result is of a lower quality and looks very incomplete. Students should take note of this in the selection of models for 3d scanning.
- 3d scans that look incomplete can be fixed using the tools that Artec provides. However, if there are too many errors to be fixed, the output will differ greatly from the expected results. As seen in the example below, an attempt is made to fix the issues with the 3d scan on the left but the result on the right is not the best.
