Leave your feedback & suggestions on the Revo Scan 5

I’m not saying this is the world’s best scan but these were both fused with Advanced .15mm. One is from 5.4.2 and the other is from 5.4.3.

Thank you so much.
I will try this function in the new version.

Revo Scan 5.4
When the UI is neither in English or Chinese, release notes on the update prompt are shown in Chinese.
It is understandable that the team won’t translate the release notes in every supported language: if so I think showing them in English might be a better default choice than showing them in Chinese, for many users.
Issue is present on Revo Scan for Windows 5.4.2 I assume it is also present on 5.4.3 but obviously I won’t know until another update is pushed by the dev team.

(here, the computer and Revo Scan UI are in French)

It will be better to keep the scanning distance setting unchanged when a new scan is started. Very often I need to redo a scan after finding defects in the previous one. Re-adjusting the scanning distance before every scan is kind of inconvenient.

Yes @new23d good suggestion .

It starting to get annoyed ately when I forget to adjust it and wonder what is going on with the picture !

Create a trash bin to allow recovery of deleted assets if needed…

Revo Scan version: V5…4.3
System : Windows 10 Pro 22H2. Intel Xeon E5-2630v3 (x2), Quadro K5000, Telsa K20, 168GB
Scanner: MINI 2
Your feedback & suggestion:

On the dual axis turntable be able to set the number of rotations you want done and have the rotation be able to be linked to image taking.

I am completely new to this equipment having used other 3D scanners with varying success. So far I fins the system is not difficult to get around but there are areas that could use improvement. The big one at the start being linking the table rotation to image taking and being able to set the number of rotations you want to perform.

Have been experimenting with the merging function of Revo Scan 5 recently and one thing I really would like to have is aligning without merging which has been suggested by other members of this forum previously.

This wish was triggered by this case of merging the two scans of a thin wrench. Neither the marker nor feature based merging worked very well which is probably because of the symmetry of the object.

Finally, I added two more scans, one for the head and the other for the tail of the wrench and the feature-based method merged them perfectly.

The only improvement I can see is a faint seam line and slightly noisy surface at some overlapping areas. I believe this can be eliminated by excluding the scans of the head and tail in the merging process but using them only for alignment purpose.

The “select connection” editing function is found to be too sensitive in the sense that I often ended up in selecting the whole model ( fused model ) when I applied the brush to a piece of surface that appears to be isolated to me. It seems that two pieces are regarded as “connected” even if piece A has just a single point within several point distance from piece B. This goes against intuition in my use cases and wonder if the criteria can be revised or some user settings provided.

The brush selector is for use with lose points and fragments that are not attached to the main scan after fusion , you select the main scan with it , reverse the selection and remove what is selected red .
It is for big junk , for removing fine isolated points use Isolated Point Function .

Something that I would like to see, is a few more point cloud editing tools. Often I have to manually clean points that both the isolation and overlap process can seem to clean. One tool in particular would be a isolate points option that would allow you to select a group of points from the point cloud and hide the rest, making the cleaning process easier and not have to deal with a larger data set that will slow down your machine. So some form of Hide/Unhide or masking options to help remove rogue points before meshing.

Another suggestion and I think this was brought up by someone else, is to use a heat map coloring scheme when scanning on the point cloud itself. Artec studio will use a heat map color tint on the current frame being scanned which is really more helpful then the histogram. because you can see exactly if your focus point is at the right range. Something also that I thought of, is that if each point tracks whether it was too near or too far, those points could get culled during the fusion process if there is a sufficient amount of good or excellent ranged points in that point cloud. Other ideas could be using point cloud color to indicate areas of under scanning or over scanning of the subject. If an area needs more attention having a visual indication can help to make sure that enough coverage has been scanned.

You see with 3D structure light scanning areas of under scanning don’t exist , you don’t want to over scan the areas multiple time but get as less frames possible of the specific area to avoid too many overlapping . The software and hardware don’t accumulate points , what matters are the scanned angles , so if you captured 1 or 20 frames it really don’t makes it any better as most of the frames are removed in fusing process at the end to generate organized point cloud .

Regarding the distance , with this technology only the closest distance will give you the best accuracy and precision results what is in the area of excellence what measures already the distance between the object volume and the sensor , what you see in preview is already scanned model in real time based on raw unorganized frame cells .
And only the best frames will be used in final fusing processing .

The color map to indicate the surface area ( distance) would be great , however overscanning the same area again will not give you 100% insurance that it will be used in final process , for that a new algorithms would need to be written so lots of changes for the main software core and how things works . Remember that the software features works only with the current scanner’s firmware , so not only software need to be updated to make it works but also the scanners.

However good idea for the future new scanners as well .

“Runs on nearly everything” …except Linux

Did u try it with wine?

Yes, I tried Wine, VirtualBox, and Qemu. No success, the 3D graphics does not work :sob:

This refer to computer and mobile in general , not specific to OS … Nearly means not on everything .

There is too small group using Linux 1.52% share of the Desktop vs Windows 28.09% , it is not worth the money and time for development at this moment .
The monthly development costs are very high and the interest is very low to even starts with .

Another area I would like to see improvement is the Fill Holes tool. Currently I feel some quality of life improvements could be made with this tool as well as optimization. I have the liberty to use both Revo scan, and Artec Studio at work almost on a daily basis, and how Artec handles hole filling leaves a lot to be desired with Revo scan. When you start the hole fill tool in Artec, it automatically begins the hole detection and provides a list box of all the holes found once the detection is complete. From there, you can either manually select the holes from the list or just click “Select All” then the user can apply the hole fixes all at once, it might not be super complex but what it is, is very fast operation. Hole filling in Revo Scan while very simple is very, very slow. Both the detection process and the hole fill process can take a considerable amount of time on a larger or high detailed scan, whereas artec seems to not take that much time at all on a similarly dense mesh. Having a list of all the found holes also mitigates having to hunt down microscopic holes when your trying to produce a water tight model that you don’t plan to post process in another application.

You can use Laso tool and select all holes ( scan) at once and fill it .
Filling holes take little time in most 3D software it is not one second solution . It all depends of how fast your CPU is and how fast your HD can write it down .

I don’t think Revo Scan is that slow in detecting or closing holes , just couple of seconds .
