Questions related to 3D Scanning
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?
Creating orthoses through 3D scanning and 3D printing, aiming to facilitate the integration of health professionals.
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?
We want to estimate the canopy volume of trees by 3D mapping using the LiDAR sensors. Please suggest low-cost LiDAR sensors available in India for 3D mapping.

We need to proceed with fast 3d scannings in the context of architecture design procedures, and to avoid breaking the flow of thinking/developing the forms we need to do it fast, not so accurate, but enough to understand it and work with this model in the rest of the process.
I'll need to research on this but I am a beginner and need to learn from the start. So, I hope someone can give me like a starting point. I've searched a lot, and there are a lot of ways of doing this, but on what way it can still be improved? I hope someone can help me on this.
I am currently working on a research project on 3D scanning (3D scanning of objects) with an Xbox360 camera, do you have any idea about the best mark of the camera?
I am trying to 3D scan an object to create 3D point cloud to understand the shape change from its previous condition. What would be the best way to do so?
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
I am working with Point Cloud alignment and I would like to know, based on your experience, which was the best alignment algorithm suitable in your application:
* ICP (Iterative Closest Point);
* CPD (Coherent Point Drift);
* NDT (Normal-Distributions Transform).
Also, good practices as filtering and other methods related would be very appreciated.
Thank you very much.
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.
i have a stl file from a 3D scan and it is just a surface modell. For my work i need a solid modell. In some other forum they told meshlab can create solid modells from surface modells or stl files. Some users says something about a make solid tool, but i cannot find it. I have a closed surface modell and just want to fill it.
How can do it?
ich habe von einem 3D-Scan ein Oberflächenmodell aber für meine Arbeit benötige ich ein Volumenmodell. In anderen Foren habe ich gelesen, dass Meshlab in der Lage sein soll Volumenkörper aus Oberflächenmodellen bzw. stl Dateien zu erstellen. Manche Benutzer schrieben sogar was von einem "make solid tool" dieses konnte ich bis jetzt jedoch nicht finden. Vorliegen habe ich ein geschlossenes Oberflächenmodell welches ich "ganz einfach" füllen möchte.
Wie kann ich das machen?
Living in New Zealand there are no carrots flowering at the moment. If anyone knows of where i could get a carrot flower 3D scanned -it would help greatly. I can send someone over to the lab to do the scanning if need be. What we need is a carrot flower ad a high quality 3D scanner.
I have performed 3D scans for fluorescence studies, which consist of contours at the emission wavelength. how to draw useful information from these 3D maps and to understand the dynamics of the reaction? Kindly give the possible explanation for the image file attached.

Would you please someone help me about the details of FTP method for 3d scanning. All the articles just repeat the general outlines.
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?
Hello, im a MA student currently working on some research projects. I would like to ask you for some advice (if this is not the place just tell me).
One of the research im beggining with is about 'new digital technology uses in conservation of art' (3D scanning, ink-jet transfer reintegration, 3D reproductions, etc) . I was looking in to related bibliography or other information but there is not much of it, so I would be gradefull if you suggest some information or examples of new digital technology used in conservation, or if you know any book or institution (i.e. factum-arte) regarding this topic.
Basically I intend to start ground truthing of SRTM-30 DEM and Jaxa 30m DSM, if anyone has calibrated the said products, please reply with operational answer. Thanks.
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)
Thanks in advance,
Maybe some Matlab code ?
Are there solutions to solve projective distortion or perspective aberration in 3D scanning and book scanning?
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
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.
I am preparing 3D model for relationships between 3 explanatory and 3 response variables using Response Surface Methodology (RSM). Any Video tutorial link?
I need to perform Micro-CT scan of porous scaffold to check the interconnected porosity of this scaffold. I want to know where this facility is available in India?
We are looking for a low budget scanner (laserline or structured light). The resolution needed is 1mm (that's quite low!!). Distance to object: 100-300 mm. Does anybody know a product fulfilling these requirements?
We’re conducting a project on documenting the wear on a stamp used for countermarking roman coins during the reign of Augustus. The aim is to try and establish an overview of the movements of the Roman Legions XVII, XVIIII and XIX and their commander Quinctilius Varus in 9 AD, before being annihilated in the Battle of the Teutoburger Wald. Does anybody know about the application of high-resolution 3D-Scanning, preferably structured light, on the documentation of coins from any period? For more information (sorry, at the moment in German only) see here: https://www.youtube.com/channel/UCcYZ1HPFYFW6WLzJecicVDQ and here: http://archaeologie.sachsen.de/5155.htm

How to make a real 3d scanner using a Kinect sensor for Simulator mechatronic machine. Can anyone help me with 3D scanner with the kinect sensor?
This pot is from an excavation and I would like to calculate the volume inside the object. There are several missing pieces that I am afraid compromise the volume. I have so far used Geomagic verify, selected all of the polyfaces and clicked calculate volume. Is this all or do I have to fill the pot somehow?
I attach an image showing the pot scan.
I have this model from 3D scanning. I then make it hollow using Magics software. I want to make it a solid part in order to cut the back side to make this model looks like a mask. Anyone have an idea?
Can anyone recommend me a good spectrometer (or spectrometer system) for mineral objects research?
Not mineral composition is studied, but the surface of mineral samples (or internal structure, if the object is transparent or semi-transparent). Thus, it is desirable to obtain not integral characteristic, but distribution (i.e. analysis in surface points).
Now I use a combination of Standa positioners and fiber optic spectrometer of Ocean Optics (as well as own processing), but maybe there is something better and more efficiently.
Spectral range: from UV to NIR
We would like to use 3D scanning laser to measure erosion rates in badlands and to measure the volume of retained sediment by check dams. First aff all, we would like to know something about the accuracy of the method. Has anyone used it?
