What is the EinScan H?
The EinScan H is a hybrid structured light and infrared handheld scanner designed for scanning people or taking textured scans of large objects.
The scanner is available in the Digital Transformation Suite to use in the space.
This scanner supports coloured (textured) scans.
What could I use the EinScan H for?
The EinScan H is best for scanning people and uCreate have a human sized turntable to help with scanning. The scanner has a specific mode for scanning hair, which is difficult to scan with other scanners.
If users are wanting a scan of themselves, they will require another person to take the scan.
The EinScan H is designed for scanning people and therefore usually, if you want to scan anything other than a human, another scanner will usually work better. However, for large objects where texture is required, the EinScan H can be used. If you are planning to use the EinScan H not for scanning a human, we recommend consulting a member of staff for advise.
Where can I access the EinScan H?
The EinScan H is available in our Digital Transformation Suite (uCreate Main Library, First floor, room 1.15) only. It is not available on our loans service to take outside of the makerspace.
If you would like to do human scanning outside of the makerspace, please use the EinStar, available on our loans system.
Top Tips for scanning with the EinScan H.
Connection and license error
If when you open up the scanning software, the scanner does not connect, ensure that only the scanner you want to use is turned on. If multiple scanners are turned on, your scanner will not connect.
This can also cause a license error.
Scan in pairs
If you are wanting to take a human scan using the EinScan H, you will need a friend to scan with you.
If you are planning to take a full body scan, uCreate has a human sized turntable underneath the scanning table in the Digital Transformation Suite.
Texture flashing
Having texture flashing turned on, increases the quality of the texture data in your scan. However, if you are scanning a person's face, this can be very unpleasant.
We always recommend closing your eyes if you are using texture flashing. It is extremely important to check for any photo sensitivities before scanning.
Scanning distance
The EinScan H has an optimum scanning distance.
Use the light on the back of the scanner to monitor your scanning distance. When the light is green, you are the correct distance away. The light will go blue or red if you are too far away or too close.
How to use the EinScan H.
The software for the EinScan H is very user friendly as walks you through the process of calibration and scanning.
For a written step-by-step of how to scan, see below. This break down details how to scan a person with the EinScan H. If you are scanning an object, you will likely want to take multiple scans that will need aligning. The process of doing this is the same as for the EinScan-SP.
Setting up for your scan and Calibration.
Calibration is only required when there is a change in the lighting of the environment. As the EinScan H is use for in the Digital Transformation Suite only, you will likely not need to calibrate the scanner.
If you scan results are inconsistent, we suggest you calibrate the scanner.
1. Start EXScan H Application, with the scanner plugged in and turned on. Ensure all the other scanners connected to the scanning computer are turned off.
2. Create a project and save your project to the folder ‘User Scans’. Title the folder with your name and student number.
3. Click on calibration at top of screen. Take the calibration board from the holder on the left side of the desk and set up as shown on screen. Follow the on screen instructions for standard calibration and white balance. You will be rotating the scanner and moving it towards and away from the calibration board. The white balance calibration uses the opposite side of the board.
4. When using the EinScan H, you will most likely be scanning a person and therefore using the infrared mode. Select IR mode.
5. Select new project group and select the folder you made earlier.
6. Select the scan mode (most likely human scanning), align by both features and texture and select your resolution. We recommend medium resolution (1.0mm) to balance quality and ease of scanning. The higher the resolution, the longer your scan will take and more easily it will lose tracking.
Setting up and taking a scan.
To set up your scan there are a variety of different settings to adjust in order to get the best result. When scanning a person, you should try to only take one scan only, as it is impossible for someone to stay completely still between scans.
7. Adjust the brightness of your scan. Click start scan to enter scan preview. On the display panel, look for some of your subject to be highlighted in red and for the persons form to appear on the screen.
8. If the scanner is not picking up the person you are scanning, or is picking up a lot of the surrounding, during the preview, you can adjust the working distance.
8. Turn on texture flashing for improved colour data (always check with the person you are scanning), hair mode (if the scan will involve someone's hair) and the data quality indicator.
9. Point the scanner at the person you are scanning and click play on the back of the scanner (or on screen) and slowly move over the person to scan. We recommend keeping an eye on the screen to see what data has been captured and to not go over a person's face more than once. Click the play button again to finish scanning.
Cleaning up and meshing your model.
When using the EinScan H, the scanner will capture both the person and space around it (for example the ground the person is stood on or the chair they are sat on), you will want to clean up this data before continuing.
If you are looking to make an STL file from your 3D scan, the easiest way is to mesh it inside the EinScan H software.
Meshing is the process of drawing polygons between all of the points captured by the scanner to create a model.
10. After your scan has finished, you may want to delete some points to clean up the scan. To delete points, select the lasso tool, hold shift, select the area you would like to delete, and hit delete.
11. Once you are happy with your scan, click ‘Global Optimization’ and ‘Mesh Model’.
12. Select watertight or unwatertight (for 3D printing, your model must be watertight). Select your quality level, we recommend medium and set your maximum number of triangles. We recommend to have your maximum number of triangles set to 300,000. This will make a file less than 25MB and can be open in TinkerCAD.
13. Click preview to preview the result. The software will now generate your model, this may take a few minutes. If you are not happy with the result, you can go back and adjust your parameters. Click confirm when you are happy with your mesh.
Post-processing of your mesh and saving your scans.
After meshing your model, you are still able to make small alterations, as well as saving your final product.
14. If you want to reduce your file size, you can simplify your model by reducing the number of polygons.
15. If you selected unwatertight model during the meshing process, you can retrospectively fill in holes in your mesh. This can be helpful if you only want some of the holes filled. Hole filling will be greyed out if you chose a watertight mesh.
16. On measurement panel, click measurement tool. Select two points to see distance between them. You can also see the surface area and volume. Useful to take measurements you wouldn’t be able to on the physical object.
17. Click export scan and save mesh locally. Select file types asc (whole scan), stl (form data) and obj (form and colour data). When saving as an obj file, a jpg file will also be generated. This must remain with the obj file to preserve the colour data. You may want to scale your scan before saving to make the size of the model more manageable in other 3D software.
