I'm looking for a batch processing method for Jasco interval data files (.jwb) to an open format such as ASCII (.csv or .txt) or JCAMP-DX (.dx). Jasco SpectraManager allows for individual jwb files to be manually exported to csv or txt. This is cumbersome when you produce many hundreds of 3D-scans.
I'm aware of a few options which will batch convert Jasco 2D jws files, but none of these support jwb file extensions.
anything similar out there for the jwb's?

I am looking for a software tool that will enable me to interactively display 3D scans on the Web.
My 3D scans are currently available in STL format and in Wavefront's OBJ format. To set up a Web visualization now, I would need a suitable Web viewer that I can integrate into my own Web application (HTML).
I would also like to annotate the 3D scans, i. e. provide additional text labels and arrows. Here the question arises to what extent it makes sense to compose these annotations from primitive STL or OBJ elements or whether it makes more sense to choose other more suitable 3D formats (which one?).
Who knows suitable Web tools and 3D formats?
Relevant answer
Answer
Another possible way might be the following:
Take the OBJ file, "render" it with the three.js library, and obtain a WebGL scene.

Question

Hello everybody
I am eager to know what is the procedure in software like Catia, Cloud Compare, Geomagic or etc, that remove noise from Point Clouds(PCs); especially when the PCs does not contain RGB or intensity information and it just contains 3-D coordinates of points. (e.g.PCs are obtained from laser scanner. )
Thanks in advance
Relevant answer
Answer
Hi Elnaz,
From your listed software, I'm most familiar with CloudCompare. I like it because it's quite "open" as opposed to (some) commercial PC editing software, not to mention quite powerful as well. As far as I undertand it, CC's noise filter uses an SOR (Statistical Outlier Removal") based algorithm. Essentially it computes a local plane using a neighbourhood of points, and then tests the Euclidean distance of each neighbouring point against this local plane. The point gets deleted if this distance is farther than the set threshold value.
If I remember correctly CC also has an implementation of the "pure" SOR algorithm in which the point's Euclidean distance is directly taken into account instead of the distance towards the local plane.
Hope this helps, and in any case I encourage you to join the CC forum (https://www.cloudcompare.org/forum/) and also the CC wiki (https://www.cloudcompare.org/doc/wiki). They're very useful resources and many questions are answered readily by the community.

For example i use Leica RTC360 scanner for terrestrial data acquisition and i like to perform a stitching with point cloud gathered from UAV photos (not lidar). What is the best way to do so?
I am pretty confident that Leica Cyclone can manage this task but i am looking for opensource (like Meshlab or CloudCompare) stable solutions for that purpose. Also in need of work flow description or experience in this case.
Relevant answer
Answer
Hi Nikita,
NDT does not require initial alignment of point cloud and still gives better data registration although processing time is more in comparison to ICP. I would suggest using point cloud library for data stitching. It is open source and you use the code straightaway. Here is the link to NDT and its implementation in point cloud library. If you are not sure how to use it then probably start with cloud compare and use ICP after roughly aligning your point cloud.
Here is MATLAB implementation of NDT
MATLAB implementation of ICP
To achieve more accurate result you can use local point descriptors provided in point cloud library for data registration or point cloud stitching.

We are using an optic 3D scanner to have a 3D view of soil surface and then using GeoMagic software to have some quantitative results.
The problem is to find volume of some rills on the soil surface or the volume of soil decreased between two 3D images.
Is there any function in GeoMagic or other 3D softwares to differentiate the volumes between two 3D images?
Relevant answer
Answer
so the best way to do this would be to first segment the image to extract the soil rills. This is where deep learning could come in to your problem (though there are a number of non-deep methods that could also solve this). First, you would want to take a bunch of raw images, and manually identify which voxels are rills (giving them a label of 0) and soil (giving them a label of 1) to give you your "correct" outputs. There are a number of tools to do this; I know of several people using ITK snap (http://www.itksnap.org/pmwiki/pmwiki.php) and they seem to like it. You would then feed your model the raw input data, with the supervised outputs that you also feed your model being the "correct" outputs that you had manually segmented previously. For development of a model, you could use something like tensorflow if you really wanted (deep learning toolbox), or could use other non-deep methods that would probably perform well if your sample size is small.
Once you have trained your segmentation model, you can then simply apply it to new data to segment the rills from the soil (ie, given your initial image, you would then get an image that is is identical dimensions and takes a 0 for rills and a 1 for soil). Then, simply sum over the entire image to obtain the volume of soil in voxelspace. Note that this also translates very easily to computing the volume of the rills in the image; you can simply take (total number of voxels) - (sum(segmented image)) and will be left with the non-soil volume. You can obtain the true volume by just multiplying volume in voxel space * (volume per voxel) which will be a function of the camera resolution. You definitely should not just take the raw data and subtract it.

Hi,
I want to analyze a size volume of intense spots in a MRI data file in FIJI (ImageJ)
I firstly project this file to 3D format using the Stacks -> 3D project tool.
Using the point tool, I can select which intensity should be used for calculating (for which I now only know 3D object counter, but this is a bit messy in my view, options? :) ).
Then using 3D object counter it calculates the amount of available spots.
But now I want only to use part of the 3D scan (which I compiled first) to be able to analyze only the intense spots in the frontal lobe and prefrontal cortex and in the hippocampus.
Is there an easy way to calculate this? (total volume of hyperintense spots in frontal lobe and hippocampus from MRI (.nii) data)

Are there solutions to solve projective distortion or perspective aberration in 3D scanning and book scanning?
Relevant answer
Answer
Hi Lode,
to rectify (and correct) 3D data (if you use 3D structured light scanners), you can use two FLOSS: MeshLab or Cloud Compare. They work with 3D data and can rectify them with known points (e.g. you can use som CGP). Than, if you extract an orthophoto form the 3D models there should not be aberrations. Here an old videotutorial: http://arc-team-open-research.blogspot.it/2014/09/georeference-mesh-using-reference-scene.html This would be the ore accurate and precise way, but for book's pages I guess that, like you say "is an headache". I think for book's pages would be simpler to work in 2D photogrammetry with images from normal scanners like the one you are using.
If you work in 2d, the best way is to use a photogrammetry extension of a simple GIS (a FLOSS one is QGIS). This would be a simple and good enough solution. If you want something simpler (also when less precise and accurate) you could also simply use a normal raster graphic software (e.g the FLOSS GIMP which is like Photoshop) and remove distortions and aberrations. For instance within GIMP you could remove lens distortions with a specific plugin and then, considering the page size, use the "perspective tooll" to adjust aberrations.
If you want, send me the image of a page and its real size. I can try to record a short videotutorial.

I know the old methods are : impression and cutting through the crown
how about 3D scanning can any one explain the used programs , also is there any other recent methods 
Thank you
Relevant answer
Answer
There is something called as replica technique, i.e., light body in layered on the internal surface of the crown and placed over the tooth or die as we do with luting agent. After the light body sets, the crown is removed with the light body intact on the inner surface of the crown. Putty placed and allowed to set over the light body. After setting the putty is retrieved with the light body attached on it. This is then sectioned as per requirement or the area of study and observed under a Stereo microscope or SEM. Other method that I had thought of while doing my thesis study was, scan the die and scan the internal surface of the crown. The data acquired could be compared. the over all surface area of the die can be measured as well as the internal volume of the crown. Comparing both the values could give us an overall discrepancy. I understand your concern not to destroy the crown.

With the technology of 3d scanning, I was wondering if anyone in the NIRS or EEG research community has utilized it for acquiring 3d digitizer data aside from the Polhemus. My lab uses the Polhemus, but it is often prone to funny errors and data that doesn't look great when we use it for localizing channels. Was hoping to find an easier and faster way and if that is even out there.

Hi Andrew,
At the Donders we have considered this for EEG rather than fNIRS. As alternative to the Polhemus, we tried a Fuel3D and as of very recently got ourselves a structure.io scanner. We did not like the Fuel3D for various reasons, but the structure.io appears to work quite well. We just added support for its data format in FieldTrip (see http://www.fieldtriptoolbox.org, it is in the ft_read_headshape function) and will continue working on this to get a good (EEG/MRI/headmodel) coregistration pipeline documented. I hope that our efforts will also be helpful for fNIRS, for which FieldTrip is also useful.  If you want to chime in in detail, please do so at http://bit.ly/1SPRkto

Almost every CAD application (SoidWorks, Creo, CATIA, Siemens NX, ..) has a module to deal with imported geometry.
