Wow Josh , that’s a lot of pages to read , most of the workflow changes because of the software updates , but in majority it is still the same workflow, I only changed recently my tactics when scanning in color , it seems like having just whole rotation is not always enough for proper textures that need more angles to be captured , so sides, top and if possible bottom , it eliminates the artifacts a lot .
In our early discussions we tried to find a way around the software bugs to do the job better but as the program improved, a lot of the tricks and tips is no more nesesery. You will need to filter them out .
I am on this moment not so happy about the new point cloud fusing , too messy , when using it in another software , half of them are not even fused proper and a lot of lose point , but the team working on the improvement, that was all good but got broken again in the process of fixing the texture mapping , so as usual one thing get fixed another get broken, bitter sweet situation
Sometimes I am thinking to make a proper PDF tutorial and put everything together but it will be not actual by the next update so just waiting until everything get rock solid and stable .
Most of my simple ways you will find on my YT channel, just click on my icon for link .
If you encounter any issues on the way just post in the tread , I would be happy to help you out.
Someone asked me to share my YT-1000 dual axis setup so here we go .
YT-1000 is used normally in photography with DSLR for pan and tilt , it has 8 speeds for rotation and tilt and is very precise, portable , rechargeable for those that are interested to know .
It also have remote control for all functions , best part is that you can just pause your scanning while tilting or changing position without additional wasted frames , no matter what Revo device you use or windows, android or Mac , so less headache .
Since the Dual Axis YT-1000 working best when it is upside-down for the best pivot while tilting , you need to use it upsidedown.
So I printed a base with cold shoe for that purpose , here how it looks like
Here I printed myself a background holders for my pvc background, I usually use black for pop , but right now I have a red for a change as it is not visible for MINI
Btw this is the way the LED lights should be used with POP2 or MINi , not in the middle or on the sides , but above the RGB camera , one on top and one below , so you have no under shadows when capturing textures , and the textures looks shadowless.
Once the Revopoint Dual Axis improve I may use it , but for now I am good with my own setup , the ability to control it precisely is what I need and my YT-1000 deliver just that .
I like the idea of Revopoint Dual Axis but it is just not working for me the way it is now , too many wasted frames and no ability to pause, the tilt is only 29 degrees , leaving some if the model parts not scanned completely like for example under chin of figures , I don’t have that issue with YT-1000 . I like how the Revopoint Dual Axis is build , but it needs heavy improvement with the software .
I reused the base cover for POP 2 originally made by @JJCHACON to support the heatsink .
Adding 2 brackets on the side above and below the RGB camera and printed it after testing all the positibilites with light , it finally produced proper textures .
It works also perfect with the tilted Dual Axis turntables .
I also tried using Ring Light , you know the one that are used for phones , it worked fine for POP2 but was too big for MINI . Having the LED on the small tripod did not worked always perfect so this is the best solution so far , more minimalistic but works great for human scans in color too.
Now I am about to make one for MINI , it going to be little tricky as there is not much space on the bottom to fit the bracket exactly where I want .
Let me know when you have one , we need one that covers the MINI as little as possible and is secured from the bottom , the lights have little weight. Something like honeycomb base with the 2 bracket to avoid overheating is what I have in mind .
What are your standard to go setting when usings this turntable? One round 0° and one 35°. What speed among available 8 speed settings? Thx in advance and also for this another great contribution!
Thanks Ivan !
Normally one round at 0 degrees and one tilted round at 35 with the scanner at 45 degrees slightly above the object .
This is for objects that fits in the depth cam preview window.
If taller then one round at 0 degrees, then move your scanner down to object base and another round at 0 degrees, then 35 degrees tilt scanning the base then move scanner back to top of the objects and scan another round at 35 degrees.
Then put the object on the side to scan the bottom at 0 degrees.
Some objects perform better when you start from scanning it while on the side from the bottom then put it straight and continue scanning at 0 degrees, it helps with the tracking a lot .
With POP2 I like to go slightly slower with speed at 6 , with MINI 7-8
But in general when scanning in color for textured , slower is better so 6 is magical speed for the turntable, the speed for the tilt really don’t matters as you don’t scanning while tilting anyway .
I still need to make the ring helping keeping the scanning marking plate more secure for the marker mode , and print one for the normal scanning .
I will post the files soon .
I am not really sure if it is ready yet to make a video about , it is against everything I shared in the past , means breaking all the rules of proper scanning .
I am sorry that I have to say that but Revopoint Dual Axis turntable is really not usable in my book at this moment to be endorsed.
We see if things improve with the time .
The idea was good but it is poorly executed and mostly on the software that controls it .
I can do comparison between my 2 Dual Axis Turntables while scanning but it will not make anything good for Revopoint …
hello,
I did not know that it did not work well … I was waiting for your tutorial before ordering. Did the revopoint team give you any informations about an update to finally use the new turntable correctly?
It is all working fine on windows and MINI at this moment only , not yet with POP2 , the problem is not the hardware as it is all good .
The problem is how it operates via the software what I really don’t like much as it do not improve nothing for me , that’s all .
It is semi automatic so you have not much control over it , just setting the cycle push button and there it go no matter you want it to stop or lose tracking the cycle continues regardless of what is happening , not really what I expected .
If you lose tracking you need to start over , there is no way to control it .
Second the additional frames that are captured while the turntable change position adding a lot of junk data to the scan almost double of frames that is needed . So this just make the whole processing time double .
I don’t see it as improvement at this moment .
I can’t tell you to buy it and you going to be mad at me later .
As always all my opinions are my own based on my own experiences.
I never tested this device before it’s release as it was all done internal , if I did I would never agree on releasing it the way it is working right now .
I got it at the same time as everyone else.
Thank you PUTV for all the info you share. If it wasn’t for you I may have given up on scanning.
You mentioned before that the new Revoscan code has been rewritten, and that the point cloud now is very noisy (like chicken pox). I’m having this exact problem with my new POP2 and MINI (I though the scanners were bad), but since you mentioned that the previous software worked fine my hope of ever scanning smooth details is restored.
What are you doing now to scan correctly? Do you have any info on when the software will be fixed?
I’m going to hold on scanning until they fix it, because I get frustrated when my surfaces are all noise and I have to do all kinds of weird prostprocesing to get a decent enough result.
Thank you Richard ,
Glad to hear that I could help you out one way or another .
Yes the development team is already aware of the chicken skin effect on the models , the changes that fixed the textures actually induced the effect , in short the point fusing algorithms are to blame .
I do use higher denoiser settings for MINI at 6 , before it was smooth without any denoiser at all . Sadly with POP2 I can’t get as good results no matter the denoiser results, both on computer and on my tablet what actually produces even worse results than on computer .
I really loved the mobile point cloud for so long as it was just perfect as it once was in Handy Studio, sadly no more .
I think we need to let the voices to be heard about this issue more often , as it is a major issue .
I just don’t understand why one thing is fixed and another that was good got broken .
To tell you the truth , I don’t know anything at this moment to share with you .
I am not getting any feedback for a while now and that reflecting in the less good quality already as we all noticed .
Hopefully the issues I reported weeks ago are going to be addressed sooner than later .
It is sad to see a very good hardware going to waste with buggy software .
If the main core don’t get fixed, there will be nothing good at the end , sorry to sounds like a broken record today but I am disappointed as well at this moment .
These chages they made (that caused the orange skin effect) were to fix the texture calculation?
If that’s the case, I’d suggest Revopoint to revert the changes to the previous stable version, if possible. I’m no expert, I could be terribly wrong here, but after testing the texture feature and the point cloud color to make textures for my scans, I feel that the point cloud color offers a better result. Could it be?
Until they can solve it, wouldn’t a good point cloud surface and bad texture be of better use than the current state? Just an idea
The orange skin effect is mostly visible in android app Richard.
The point cloud color is RGB color per vertex data , no textures , I use it to convert it to textures.
But you have to mesh the point cloud to get out the good RGB base the easier way . Programs like Zbrush, Blender, MeshLab can do that convention .
I use early version of Revo Scan until things sort out for better again . The point cloud right now is too messy for me and need to be meshed in Revo Scan to clean it up .
