New Pop2 problems

Hi @ModPaul ,

Based on our internal testing, even average-performance laptops can run Revo Scan.

The optimized version will reduce the CPU usage to varying degrees in both preview and real-time scanning, and generally the CPU will not use 100% in these two stages, so it will not have much impact on the real-time scanning efficiency and result.

In the data processing stage after the scan is completed, the CPU occupies 100% (occupying all available resources), which only affects the speed of the processing progress, not the output result.

We think that the Revo Scanā€™s performance wonā€™t be affected. It only make laptops consume more power, so pay attention to the remaining power.

Best Regards
Cassie

That is OK, because otherwise the timing for fussing and meshing would be too long and we want the job to be done quickly . Slower CPU while capturing the point cloud data may affect the tracking /alignment of the frames , making program less efficient and slower for saving power is not the proper goal , as I said before , get rid of the preview TAB real time processing , it is not necessary and waste of resource. SCAN TAB is working the way it should at this moment .

It is the same as it is now , it uses the full CPU to capture the cloud point data , once you capture the data and click stop it is back to idle , not running all the time . It get active again while fusing and meshing and texturing but not at 100% . I run all functions monitoring the CPU on the side , and the CPU at 96% was only while capturing the point cloud data , and the same in the preview mode what is useless to everyone as you canā€™t stop it . Waste of resources .

I vote to get rid of the preview panel , who is on board with me ?

@PUTV

Are you able to share a scan process where we can see the follliwing:

  • lighting conditions
  • Setup for scanning (Greenscreen etc)
  • workflow inside Revo scan?

Your results are nearly perfect. if i would be able to reach these results, this would be perfect for me

Thank you in advance.

You are right, unfortunatly this is not fixed yet. Saw only the note with the enhanced depth cam thing. which is useless for me.

This could be a problem. Revopoint includes a black plastic sheet to use as a background to prevent interference because it absorbs infrared light. Many black fabrics reflect infrared, so they are not useful.

It is possible that the plastic components you want to scan are made of a material that absorbs infrared, so they will be very difficult to scan unless coated with a 3D Scanning spray.

I did some research while composing this reply and saw the statement, ā€œAll plastics absorb in the IR. To determine which ones absorb the most, you would have to look up or determine the molar absorptivities of the functional groups in each polymer. Donā€™t forget path length. Sheet will absorb much more IR than film.ā€

Soā€¦ your problems could be due to the type of plastic you are attempting to scan.

This light fixture is designed to fit in a standard photo accessory mounting shoe. Revopoint used to sell a chassis that would hold the POP, battery, phone and LED light, but I cannot find it on their website nor on Amazon.

If you have this kit, https://shop.revopoint3d.com/products/power-bank?variant=42266285015275 , the cylindrical battery pack that doubles as the hand grip has a 1/4" female thread at the bottom that will allow an additional mount (say, something like this, https://www.amazon.com/UTEBIT-Straight-Speedlite-Compatible-Photography/dp/B07PTQXS79/ref=sr_1_4?keywords=1%2F4%22+mounting+shoe+camera&qid=1651267434&sr=8-4 )

@JeffLindstrom . That is true Jeff , also WAX will absorb complete IR , the reason I am using Zinc Oxide in my 3D Spray mixture as it reflect IR and most all UV lights . The Color does not matter , what matters is the material the object is made of . Most scans today has combination between Infrared and LED light to helps with that issues.

The problem that @giuspa has is tracking , as we discussed it already in a different thread , to many flat surfaces , the only way is Marker mode with markers to accomplish the scanning of that object .

Hi all,
I just got my pop2 last week and after a lot of trial and error managed to get an accurate scan of a timing cover. Accurate meaning that all the dimensions and bolt holes are correct. I positioned the pop2 on a tripod angle to capture the edge to center of the cover on the turntable at a distance 15-25cm when rotating. This let me scan all angles of each side. one scan for inside and another for outside.

My issue is not getting a smooth surface. It looks like a pebble road. I tried post processing with most versions of the free software out there but then I lose the detail of other important features. The cover is BLACK Plastic. Took me a while to figure that outā€¦ lol. I dusted it with baby powder to finally get a full scan. I do have a can of spray on the way.

The rough texture is on everything I try, even the Bust that came with it. I did the calibration multiple times. Iā€™ve tried all kinds of photo lighting. I always use ā€œFeature modeā€.

I never thought about my PC being an issue. I figured it suppose to work on a cell phone my PC should not be an issue. Its setup on an old 6700k with 32g.

any thought would help,

Can you show us some pictures?

It would help to understand

I have to agree with all the people here with bad experiences. Working with POP 2 is very disappointing and frustrating, it always looses track or scans the object ā€œwith shadowā€. Hope there is something I can learn in proceeding, otherwise itā€™s a waste of money and even worse a waste of time.

I see only 4 possibilities , you need proper calibration , or you use too bright light that interfere with the Infrared Sensor . The gain settings are too high . You overscan the object multiple times .
Some pictures would be helpful to see exactly the issue .

With this technology that POP2 uses , there are always some very fine mini noises , but when you choice the right settings for each object , you could avoid the noises . Using the highest settings for everything will not produce the quality . The quality is in the proper settings regarding to the object .

You should have no more noises than in this example of POP2 , I used 3D Spray on my black DSLR

I dont know how to export to a jpg so I took a shot with my phoneā€¦

Also I have done ALL four of those suggestionsā€¦ lol I have 3 led lights on itā€¦ I let the turn table roll for 10 minutesā€¦ I cranked up the gain and recallibrated multiple timesā€¦

OKā€¦ I just grabbed a nicnac off the shelf. its about 9in tall. My pop is mounted on a boom mic stand so it turned it on edge and adjust for distance to capture the whole image. Set everything in the program to auto. left the slider on 1. Turned off all my lights so Im just using the room lights. Set my turn table on low speed and made 1 revolution. That give me about 1000 points. The scan was very clean. No bumps or distortion. Very smooth. I had a couple of holes cus I left the gain on 1. All I have to do is learn how to scanā€¦ Obviously I was over doing everything.

You guys are a great helpā€¦ thank youā€¦

you should capture it in 30 sec, not 10 min , this is indeed not good , overlapped multiple scans over and over will result in messy point cloud , you canā€™t make your mesh looking better than the point cloud . Can you open Revo Studio and load the " fuse.obj " from the scanning project of this object ? I want to see the point cloud .
Also having too much light will mess up your gain settings unless you use LED , you donā€™t need any light to scan with POP2 , you can do it in complete darkness too .

you can also send me the point cloud fuse.obj ( or ply) files zipped to putvmail@gmail.com for investigation and eventual solution in removing the noises in your workflow .

In Win10 press the Print Screen button on your keyboard to capture the screen image, unless you are not on PC .

That is the first step to get cleaner scans , for things like you showed above , slower rotations do better on a flatter surfaces , I scan usually at 60 sec per rotation for flatter objects , around 600-700 frames .
When fusing , use the lowest pitch point settings, when meshing keep the details mesh at value 6, and you can use denoiser at 3 . lower meshing values than 5 can affect the volume accuracy too much . It would be best when you perform the meshing in Revo Studio , you will have the chance to use different settings and use undo in case you donā€™t like the results , you can also smooth the point cloud before meshing it keeping the details . There is lots of things that can be done to improve the final mesh .

Some objects scan beautifully without any hassle , other objects needs a little work and proper workflow .

Hereā€™s an example of too many scans of the same area.

I scanned the Agrippa bust two different ways: a single 360Ā° scan and three 360Ā° scans with the bust in three different positions to get everything.

Unfortunately, there were too many points in the cloud and you can see what happened to the triple-scanned cheek.

I think Im in the wrong thread here. Dont get me wrong, you guys fixed my issue instantly and I very much appreciate that. I have found absolutely NO problems with my pop2. I received my developer spray Thursday night, sprayed my timing cover, turned off all my shop lights and turned on a night light. Scanned both sides with one revolution each having about 800 frames each. The scans came out smooth as a babys butt with perfect geometry. Thereā€™s nothing wrong with this pop2 scanner.

I am having an issue trying to align the two scans in Revo Studio. It just wants to merge them as two parts randomly attached together. I guess because one scan is the outside of the cover with the other scan being the inside. Im able to align them up in other software but they are not ā€œwater proofā€ so the stl is not sliceable. Hence, looking for the Revo Studio thread.

Thanks for being hereā€¦

The way to avoid this problem is to have some overlap so that a few of the same points in one scan are also present in the other scan.

Then, in Revo Studio, you use the manual mode to place markers in each frame for the same points (at least 3, but more is usually better).
