Recap Import Problem With Some Faro Scans

Anonymous — Fri, 10 Jan 2014 15:38:18 GMT

First of all, let me state the I really love Recap Pro (pricing schemes aside). At first I thought the interface was weird (ala Poser or Bryce), but I really like the concept now and can appreciate the "form follows function" layout with an emphasis on visual feedback. They really thought outside the box on this one.

A client has recently paired with me to provide extensive point cloud support services and though he was advocating Faro Scene, without reading a manual, I started importing, registering, indexing, editing and then unifying 20 vehile and scene scans in the last month with the trial version of Recap Pro. He says I've been turning the work around 6X faster than the way they were previously processing the data. I recommended we stick with Recap Pro and he agreed (and he is also keen to scrap the plastic balls he has to carry around when on the road).

Now for the bad news:

Two days ago, my client sent two more scans my way and both of them will not import. We are on a tight deadline, my Recap Pro trail (the latest version) ends in 8 days and I have to pull the trigger on a full license. Now this hiccup.

My first thought was, "Why was I able to process 20 scenes and suddenly I cannot process these two?" The first problematic job had 19 individual scans and when I point Recap to that folder, it brings them up instantly in a row at the top of the screen. The first one started to import, with the starting, default, blue highlight from the 12 to 1 o'clock position. Then after a minute or two the next file does the same thing. After about 20 minutes, all nineteen scans show merely the default starting highlight and nothing else happens. I've let it run overight and nothing further happens. If I start over and load one scan, after the starting blue highlight, it goes away after a few minutes and a dead circle with the scan file name in it sits there.

Wondering if I had a general software issue, I went back and imported some of the original scans that previously had worked. They imported just fine.

I then figured, "There has to be something different between the datasets that work and the ones that do not. Taking this opportunity to learn Faros data structure, I explored the scan file folder and logged the file/folder structures and sizes in a spreadsheet. An individual scan has a prefix (probably set by the cleint in the field for the scan series) called "SCANNAME###.fls". This is a folder and the ### is a numerical series 000, 001...019, etc. Within that folder is a "Bitmaps" and "Scans" folder and they each have a "1" subfolder. Bitmaps has four files all 1KB in size. The Scans, 1 folder seems to have the meat in it. There are 14 common files, Calib, Dist1, Log, MirrorIndex0.hls, etc., most being 1KB and a few 67 to 650KB. The scans themselves seem to be in the files ScanDataStream0 and sometimes ScanDataStream1 to 3. They are usually about 65MB. Sometimes there is only the "0" scan and sometimes there are "0 through 3". When that happens 0-2 are 65MB and 3 is 6.5MB. The root "SCANNAME###.fls" folder has a 1KB ",classid" file, a "Main" file about 32KB and a file that matches the root folder name ("SCANNAME###.fls") but listed as 0KB.

When comparing the scan folder that imports with the scan folder that doesn't import, the folder structure, files and file sizes are consistant. I cannot see any difference between them.

When a file properly imports, ReCap creates some files and folders itself. In the scan file root folder Recap creates three folders called RawScans, Revisions and WorkSpaceData. I've never found anything to be in these folders. There are also two files, ScanProject.fpr and temp.lsproj. You set a project filename in a designated folder before you start importing scans. In that folder Recap creates a .rcp file (Recap Project) in that directory and a folder called "(Project Name) Support". When a scan properly imports Recap generates several files within the Support folder, .rcc, .diff, etc., and all the files start with the project name. There is also an interesting "Temporary Cache Files" folder which, again when a file properly imports, Recap generates a series of .png, .jpg and other support files. The .png and .jpg's are box texture mapping sub maps; Left, Right, Top, Bottom, Front & Back 2048x2048 images that are obviouly what is used to create the VR view you get during the registration phase where you can rotate around the scene from the focal point of the scanner in each of the split screens to place the registration markers.

Improtant Note: With the Faro Scans that do not import, the folders and files within the scan .fls folder are not created and all the files within the project Support folder and Temporary Cache Files folder are not created. Recap recognises the scan file. It pops up with the circular icon with the scan filename in the circle. The blue highlight starts, then nothing more happens. No support data showing any amount of Recap processing occurs.

I've created a test dataset that can be analysed by my peers and AutoDesk. The RecapTestData.zip file online has two Faro scan folders; "GoData001.fls" will import and generate all the associated files and folders, "NogoData001.fls" will not import and no files/folders are generated. There doesn't appear to be any difference between these two scans as far as data structure is concerned.

The test data is at:

I need to purchase Recap soon. The client is depending on me to knock this stuff out. I cannot afford to be embarassingly dead-in-the-water on some scan projects. I hope we figure this out soon.

Thank you.

Hi Buck, I've tried to open the "Nogodata001.fls" in Faro Scene LT 5.2(free). It went error when I double click the scan to load it with message "Unknown file format... Error code:32". So I think the data is corrupted. Thanks, Cloud Yao

That's strange. My client found a .pts file for this vehicle that was processed from the original scans. So it worked for them in Scene.

He also sent me 20 scans of two other vehicles and they also will not load.

Perhaps he did something to the data that made it corrupt in giving it to me.

I'll verify this. Thanks for your input.

The problem was my client was using Filezilla to upload files to my ftp site. See my latest post for an explanation.

I am having the same issue, but I am the one who scanned and I have the files straight from the scanner. I usually use FARO Scene to Register the scans and then import the registered scans in to Recap and index the scans. I then go from there to Revit. I have done the process dozens of times with no issues. Although, our last 3 project we have had some serious issues and had to take the registered scans from Scene and index them directly through Revit. Well now this project I am on, Recap will not import the registered scans or even the raw scans, and Revit will not index them directly. I am on a thight deadline and need answers ASAP. Talked with a few techs and they think it is my graphics card or something, but I have tried this on 4 machines now and the same things happens on all of them. Please help

I suggest you make this a new post to get maximum exposure.

Good luck.

I am having the same issue. Last week I purchased an annual subscription. Since then, I have not been able to import many of the scans I have performed (using a Faro X330). I have attempted RAW FLS, filtered via Scene 5.2, and "Save Copy" from Scene 5.2. The scans load into Scene just fine, but hang indefinitely on the import page in Recap (v. 1.2.149.506).

Hi, Could you send me the fls file via a360? I can help you to check the import problem. Thanks, Cloud Yao

Re: Recap Import Problem With Some Faro Scans

If you can't import any FLS files, then maybe you can try to re-register Faro DLL. See details here: http://forums.autodesk.com/t5/ReCap-Pro-General/ReCap-Pro-will-not-import-previously-registered-scans-or-raw/td-p/4838327 Thanks, Cloud Yao

If you’re still having issues importing x330 .fls files here is a suggested workaround from my colleague Cloud:

" I reproduced your problem by unregister Faro's DLL. You can try to unregister it and register it again: 1. Close ReCap 2. Type cmd in search text box of windows start menu 3. Right click on the cmd.exe and select “run as administrator” 4. Select yes to open cmd.exe with administrator permission 5. go to the faro sdk folder: C:\Windows\winsxs\amd64_faro.ls_1d23f5635ba800ab_1.1.502.0_none_347e8ae1032f54af, Notice it’s the folder for Faro LS SDK 5.2.0, each sdk version has its own folder. 6. Unregister iqopen.dll with “regsvr32 iqopen.dll -u” There will be a message dialog pop up: "DllUnregisterServer in iqopen.dll succeeded." Note: if the DLL is not well registered, you may see an error message. 7. Register the DLL with “regsvr32 iqopen.dll” The success message should be like this: "DllRegisterServer in iqopen.dll succeeded." Then you can try to import FLS files in ReCap again. If you can’t register “iqopen.dll”, there may be some software conflict on your computer. You can try to close them before opening ReCap. I also attached a document with pictures"

Thank you.

I am having an import problem also with recap 2015. I have processed my scans with scene 4.8 and when i had left the scans un-cropped they imported into ReCap just fine. When i trimmed the scans in scene to show only what I needed to , the scans will not show up, as you can see the thumbnails are very dark, they were full colour before and imported fine.

Is there any specific function or feature that keeps you from being able to do these edits from within ReCap itself? In general, it's better to bring the raw scans into ReCap rather than cropping them first, however if there's a specific usecase that we don't support, we'd be very interested in hearing about it.

That said, would you be able to share any of your cropped files with us so that we can do some testing to see what might be going wrong?

richiee,

We have had our scanner for about a year now and many of our laser scans were processed in Scene and imported straight into inventor 2013.

To keep file sizes down , all of our processing was done in SCENE and any scan points that we did not need were deleted. when i am processing these scans now with ReCap 2015, I am finding that I am having trouble with many scans that have been cropped , or trimmed to only show what I needed.

I find that i have to go back to my raw scans and re process them and align to the default ucs in scene if i want these scans to be used in ReCap

I was not having any trouble with ReCap 2014 at all. 1 function that i would find most helpful is the ability to align planar faces in recap to the origin planes, I use laser scans a lot for both repairing earthmoving equipment and also, new manufactured components for mining vehicles, and alignment to the default work planes is a big help. I would be happy to send you some of the problem scans. Just let me know where you would like them uploaded to.

Thanks
