Target Point Distance, Floor Removal, Texture merging suggestions

[binadhed]

Hello!

I have started using my Revopoint Trackit and been very impressed by it, I think the software is great but it lacks some things and there are other features that I think should be added.

1. Target Point Distance: I think when I start a scan, the target point distance should not change once I choose it, this is what I faced more than once, I choose the number say 0.3mm and start scanning, finish, start a new scan and without knowing the point distance is changed on its own to a random number or a different number that I have previously chose.

which caused me lots of issues in merging later, which after 4 or 5 scans, that took around 45 minutes maybe on complex geometry, is a huge annoyance.

I suggest that when I start a project, either I have a windows that asks me about the target point distance that I will require for this project or in the regular interface the moment I choose the number it is set and locked and will not change when I start a new scan.

Also, please do let me know if there is any benefit from changing point distance in the same project, as I have no clue if there is any benefit.

2. Floor Removal: either I don’t see it or it is not available, so if it is in the software please do guide me in finding it. if not it is one of the best features I’ve used in other brands, I choose 3 points or brush or select, that are on the same plane and then it will create a plane and then gives me an option to offset the plane by whatever number I put and viola scan floor is gone. if we can get this that would be great.

3. Texture merging: I think this is obvious, but for those who didn’t use the software still and was trying to understand the feature, when I got the trackit, I scanned an object in one position, then added texture with the texture feature then went to do it in 4 or 5 more positions.

I was then trying to merge the model which it did, but the texture is not applied for the merged model.

I don’t know if it is in the plans or not, but if this feature happens, then Revopoint Scan might just be the best accessible scanning software on the market.

anyways good job guys, I will be sharing my results soon!

Target point distance reset itself with each new scan /project
It is just visual option for you to see while scanning how much more frames to collect , it do not affect the scan in any way , so if it is 0.15 or 2.0 it don’t matter since it’s only an visual preview indicator while scanning .

@binadhed

It can’t affect anything because it has nothing to do with final scan . Visual preview only.

@binadhed

Also, please do let me know if there is any benefit from changing point distance in the same project, as I have no clue if there is any benefit.

The only benefit here is that will tell you “ visually “ if you need more frames.

For example you scan a huge object 1 meter , it will require less frames to be captured so to turn the scan faster green you choice lower point distance . If you have a very small 20 mm object , you choice higher point distance settings to capture more details and it will turn green slower until you capture are the frames needed .

I stopped setting the point distance because I already know how much frames I need for a specific objects size so I check the frame count instead and make sure everything is green as well in all sides .

Floor Removal: either I don’t see it or it is not available, so if it is in the software please do guide me in finding it. if not it is one of the best features I’ve used in other brands, I choose 3 points or brush or select, that are on the same plane and then it will create a plane and then gives me an option to offset the plane by whatever number I put and viola scan floor is gone. if we can get this that would be great.

Floor removal is on the right side under the tools , you will find a brush to remove the floor as long it is not connected to the main scan , so make sure you elevate your scan slightly and do not capture them as one .

You can also use lasso tool , select the object only , reverse selection and delete everything what is red ( of course you need to fuse the scan first )

Practice with the tools in the right side , they are very helpful , please read manual explaining all the tools .

@binadhed

Texture merging: I think this is obvious, but for those who didn’t use the software still and was trying to understand the feature, when I got the trackit, I scanned an object in one position, then added texture with the texture feature then went to do it in 4 or 5 more positions.

You are merging point clouds , point clouds do not have any textures , they have only color per vertex .

You need to capture each scan with color function , after that fuse it and clean it , after that you merge the point clouds and after merging you generate textures under Texture tab .

I hope it explained all issues you had .

Please follow tutorials and please read the manual for all functions , and if you don’t find what you looking for , just ask .

You can also contact customer@revopoint3d.com for technical issues (if something don’t works right as it should )

For anything else don’t hesitate to ask . Our community members are always happy to help as well.

So you are telling me that it doesn’t matter if I choose 0.3 or 0.5mm they are all the same?? I am confused.

cause from what I faced is, if I can using 0.5mm then second scan I start and didn’t change it to 0.5mm and lets say it went back to 0.3mm then I merge the point clouds it causes issues like noise but based on what I understand from you now, that the Target Distance has nothing to do with the scan resolution? please correct me if I am wrong.

I use other software that has a plane option by only highlighting 3 spots and it automatically removes the floor, no need for basic tools like lasso or line which takes ages and because the scan is not aligned after the scan it is almost nearly impossible to get a proper flat line to remove, so this plane option is really an efficient way of doing so, I read all manuals available and it did not mention any floor removal, only manual tools which is why I came to suggest its not an issue just a suggestion.

Yes, I understand this, and this is a suggestion not an issue, that Revopoint needs to add this feature, as it is a useless feature if I cannot merge the textures, the use case for scanning using only a single scan is almost nearly impossible to cover the whole object, some probably doable but not all objects, so there needs to be a way to merge all textures just like in MIraco which uses Photogrammetry, but I think it is doable with what we already have in Revoscan, so this was a suggestion to have such an option.

I’ve seen all tutorials available on youtube, website and everywhere possible, there is so much information that is lacking (especially single line mode on trackit even though I asked for it many times on youtube and instagram) , so I came here for help.

Again, thanks for taking the time to reply.

Yes that has nothing to do with final scan , it is only optical preview viewer and nothing else , so if you scan was noisy you did not captured enough frames , I explained to you already so I guess not need to go through it again . Clean your scans the proper way before merging , you will have less issues and after merging clean them again from overlapped points before meshing .

You have tools like square selection , straight line or lasso plus brush and many others to do it precisely, including special view to get it more precise in seconds .

We have before automatic ground igniter but it was not working properly and removing more than you wish as most people lay down the scans directly in the ground, and that is the first mistake when scanning always elevate your object from the ground this way with one click you have the background removed .

Sorry I don’t use the other software so I can’t speak about .

But thank you for your suggestion

I think I don’t understand you well what you mean here .

You can’t merge textures because there is not an option for merging textures and MIRACO don’t use photogrammetry or any other scanner from Revopoint it is completely different technology .

You are merging point clouds and point clouds do not have any UVs , only meshes have UVs when Textures are generated , for that reason you can’t merge textures or meshes .

You need to follow the workflow in the software the way it was design as there are 3D steps that can’t be chanfed. Because the model types don’t support it .

Learn the software and practice , you will get it in no time.

The workflow is the same for all Revopoint scanners no matter what software you use .

Scan , fuse , clean , merge, clean , mesh, texture .

And you can’t change the workflow … it is for all scanners .

You can post additional suggestions under Feedback/Suggestions here in the forum . It is periodically collected by the team .

[binadhed]

Thanks for the reply and clarification.

@PUTV

I did not understand this previously I thought this dictates the final resolution of the scan, but now I understand it.

@PUTV

But thank you for your suggestion

I wish you can try other software, as you are a beta tester from what I read in your profile and you should have knowledge about competing products, as much as I understand that preparing the model in all aspects before the scan will make it an easier process later when scanning, but I guess because I got used to this feature I now feel that Revoscan is lacking it as an important feature, and I hope they do implement it soon. I would have mentioned what software has it but I assume it is against forum policy to do so.

@PUTV

You are merging point clouds and point clouds do not have any UVs , only meshes have UVs when Textures are generated , for that reason you can’t merge textures or meshes .

I thought the single shot mode on the Miraco uses photogrammetry, I don’t have one I have just seen it online, but anyways, I have another scanner that I can merge all point clouds and it will merge texture just fine, so if it is a feature in a different brand I think it can be a feature in Revoscan, I really am liking Revoscan more than other software I have used up until this point for scanners and I just want it to be better.

Again thanks for your time.

This doesn’t seem to work with Revo Track. Texture is greyed out for merged scans, even when the components have captured images.

I will check out with the dev.team after they are back from the holidays .

Looks like the public version don’t have it yet, that explains a lot, thank you for letting me know.

[phillipkeane]

He is referring to texturing merged scans and he is correct.

With the MetroX is is possible to texture every side of an object.

If I am scanning a 6-sides shape with the Trackit (such as a cube), then I can scan each of the top, front, rear, left and right sides, then texture it.

If i want to scan the bottom, i can flip the cube on its back, scan the bottom side, then merge the bottom side with the other 5 sides.

But we cannot scan and take textures of the first 5 sides, flip the cube over, scan and texture the bottom side, then merge them into a fully textured model.

Unless the item being scanned is suspended from a wire, it is not possible to create a texture of all sides.

@phillipkeane

He is referring to texturing merged scans and he is correct.

Yes because texturing using Trackit in laser mode is not the same as with Full Field, so each side /angle of the scan will not have texture data color per vertex. , it works a little different for that reason it is not available after the scans are merged from multiple scans.

[TheBoatScans]

Even if we lose reference to the captured images after merging, it should certainly be possible to create point clouds with color prior to merging.

[PUTV]

Yes it would be possible , but it would need to be created before merging so all color data is linked to the merged points to be able to recreate the whole texture as it do with Full Field scanning .
But there is a hole in this system , and R&D need to find a way , as we talking early , there should be a separate option for all scanners to be able to separately texture all scanned object after meshing using not only the scanner RGB camera but any camera for that matter. It is possible , just someone need to make it available , it would be much more appreciated than the way it is now . I think it would just push Revopoint on the next level from the competition.

Until then we going to run on one leg
