Metro Y Pro: Poor cross line scanning performance

Support & Feedback
1

Hi all,

I just received my Metro Y Pro in today. This is my first 3D scanner, so I’m very inexperienced.

I’m using the Revo Metro software. I’ve completed successful scans with the Full Field scan option, the parallel lines option, and the turntable option. All the scans come out great, and marker placement seems to be fine.

However, when I try to scan with the cross lines option, all I get is a mess of a point cloud (literally it’s a giant ball of points). When I’m scanning the distance meter bar on the right is jumping around everywhere, and it looks like it is having issues picking up the markers. I can’t get any green areas at all.

I’ve tried re-calibrating the scanner as well as adjusting the laser brightness and depth exposure. None of the options work. The preview window on the left is very very dark, and I can’t see anything. Is it supposed to be like this?

My computer is old, Ryzen 2700x with RTX3080. I don’t see how it could be an issue though seeing as the other scan options work fine and produce great results.

Hi @rjg13

The laser mode only capture around 20% per sec compared to Full Field
So the workflow is different , you need make sure you move back and forth the scanner and capture at least 8K-10K if frames before fusing , it’s a lot more work than Full Field

Make sure you have the proper settings for the object color surfaces , don’t use too high settings for light materials as it will capture everything around create ball of noises .

You can show done a red shot preview of the viewport after collecting some frames for evaluation what is really going on and if something is wrong or just new user error .

I understand that laser is different than full field. I have successful scans with single line and parallel line (pics attached). Whenever I try to scan cross line mode, it gives me a garbage scan.

Here is a scan I just did. There is a picture of the part with markers. I have settings of my screenshots, and a video of the scan as I’m performing it. You can see in the videos that the cross lines scans are terrible, but the parallel and single lines scans are okay.

From what I see the metal is completely reflective and that can be a huge issue here ( shiny metals yes, reflective not )

but the most issue is the Exposure settings on the Depth camera that even the markers are blasted off , I never used depth camera settings at this level .

If you over exposing the depth camera there will be nothing to see by the sensors.

Please try the cross mode with the included bust , set the depth exposure at level 1 and the laser exposure at 5 and try again to test the laser mode .

Of scanning fine , you can test the settings for the metal at lower settings , if the bust or any other white objects do not scan then you will need to make appointment with technician at customer@revopoint3d.com

But I am positive it is just the depth camera settings blastic the surface off here on the reflective surface .

You see the laser lines need to be projected on the surface to be visible to the sensors , if the surface is too reflecting it will bounce the laser in any directions for that reason polished metals and mirrors are a bad candidates for scanning without 3D spray no matter $60K scanner or $1K

I’m sorry but I don’t think you are understanding me. Please watch the videos.

The scan with parallel line mode is fine.

The scan with single line mode is fine.

The scan with crossing line mode will not work at all.

These are all laser scan modes.

I understand very well , with this exposure settings you will not capture anything , it is much too high .

Please follow my advice first to test it out and if still not working you will have a case by the technician .

It is possible that there is something wrong with but for that you need to run first regular test anyway with a regular object .

Please include the link to your thread here when you contact customer@revopoint3d.com for technical assistance with your hardware .

Yup you were right. Works fine with the lower exposure and lower laser brightness.

Are there any resources that explain how to dial in the right settings or is it just trial and error?

The settings are based on the material surface , common sense in 3D scanning objects that are made from materials that absorbs in this case blue light needs higher laser settings and slightly higher exposure .

Example ,
White objects
Depth 1
Laser Brightness 5.
Gray objects
Depth 2
Laser brightness 7

And how darker it gets how higher the settings .
Remember red color is nothing else but middle gray so it will require much higher settings .
Black plastic is made from oil , oil absorbing very much must light source , it need the highest settings .

But black cotton absorb as much as white cotton so there is not difference at all , because it is not much about color , but about what the material is made off.

White wax will be as much absorbend as middle gray or more , physics in the work here .

Then you gave yellow, orange and brown colors that actually a driving blue light the most and need the highest settings .

But I will not get crazy about with the depth exposure , choice first the proper setting for surfaces from the menu … This means laser brightness first , if is not enough add manually higher level , and avoid too high Depth exposure , laser brightness is most important .

Hopefully in the next Deck Metro build the Auto settings will be back so all you will have to do is point on the surface and let the Auto mode control its brightness .

But it is worthy to learn about scanning surfaces and how it works in practice to avoid frustrations, professionally you should use 3D spray on your surfaces and care less about the settings , but if you want to save money and time scanning without it , a little learning and practice pays off .

Don’t skip this tips , you will need it in each new scanning session.
If anything just ask , I would be more than happy to give you another tip if needed.

im having same issue

The cross lines function is very finicky. I think it’s best when you’re scanning a large flat part. I’ve had some success with it, but overall the parallel lines option works much better.

11

it suck because i wanted to use it since it was going to be faster

12

even my wireless does really work

13

You mean you have a new user error issue ?

14

You need to set it up in your system so it don’t switch to Internet meaning cancel automatic connections if I ternet is not available . MetroY series network do not include Internet for that reason your system will try to switch to another network

16

I disagree, it is just a laser scanning and that is totally different than Full Field , take longer time and patience .
Cross lines are the fastest and MetroY pro have the fastest cross line available on the market in the same price range .

I scanned coins and small bolts with it , works really good with small objects as well , but you need to collect a lot of frames to get the proper result , so different workflow

Don’t bash a product based on your new user experience , it don’t deserve it . Instead follow up to learn how to use it and create your own new workflow that fits you best.

17

not new user i have tested many scanners as beta tester cross line not very good i was just tester for competitor s1 and crossline was smooth as butter hopefully this is just software and wireless is not that great at this point .

18

and we are not bashing anything i own many revopoint scanners

19

I work in this field for 30 years , you don’t have to explain to me . But good to see you started to learn how things works , but don’t assume that every scanner works the same way. Your need to develop your own workflow that works best for you and use modes according to different objects in question. Practice is best thing to make it perfect.

One more thing
If you going to attack me personally again for nothing but trying to help you , I will suspend you . I am not going to ask again.

It was not addressed to you

no i understand so your y pro in crosshatch is good putv?
