I did find only one 3d scanner which uses structured light. There is many projects using a laser diode. And these systems are completely opensource.

The easiest way is as you currently do: model the pieces by hand, using (digital) calipers to measure them. Scanning technology isn't very good, and the models are not of printable quality. Usually, fixing a scan is more work than modeling an item from scratch.

There have been instances where people have replicated a key from a photograph of a key. A multi-minute scan of a key seems like overkill, but that appears to be a very large key so maybe so. Is it possible? Yes. Is it exaggerated? Probably much simpler than is portrayed. Is it fiction? As portrayed, yes. Practically, no.

If the design was made from an artist and is not public domain, than you should not upload that scan without the (written) permission of the creator of the design. Espacially a scan of a decorative object will likely be protected, so costumers buy the original instead of printing itself or buy a printed version. If you would design a deco object and sell ...

Because my research shows that LAS files are point cloud data, you would first have to convert the point cloud to a mesh. Point clouds are just that, data references to points in 3d space. A printing service works with files that represent planar surfaces, properly joined (watertight, aka manifold) to form a solid or solid surface model. The only resource I ...

Usually, the largest variability in 3D imaging is lighting, closely followed by the color scheme. You'll probably want to heed some of the following points: No colors in the background/stand, keep to shades (unless otherwise specified for scanner) No gradients. This applies to poor lighting causing a "gradient" light effect Set the backdrop beyond the range ...

First thing to do is get a lawyer skilled in copyright law as applicable where you live. It's going to depend in no small part on whether your scanned model is considered a copy or a transformative work of art. Personally, I see scanning an object as similar to photographing it (or sketching it). Lots of art objects, or for that matter personal items ...

I don't know the probe, but I have used a delta 3D printing machine (of my design) to scan a surface. It takes some time. Your resolution will be limited by the probe geometry of the touch probe tip. You want a Z-probe function that reports the Z-value of the point, not that simply sets Z= when the probe "hits". The RepRap firmware has this in the G30 ...

Same menu, different location in the sub-menu (at the bottom): As T.M. states in their comment, see Poisson mesh reconstruction on StackOverflow: MeshLab 2016 now uses the new version of the Poisson merging, and the filter is called: Screened Poisson Surface Reconstruction it is in the same submenu, on the bottom. The relevant parameter (...

A good free tool for editing meshes would be Blender. Linux, Windows, Mac are supported. It has a serious learning curve, and is somewhat counter-intuitive in use (right click object to select) unless you customize it. Plenty of online video tutorials to learn the basics, though, and if you have a membership for Lynda.com, those videos are the best (opinion)...

I tried the same setting old kinect (but for PC - actually with power supply and usb-cable) plug to my surface windows10. After some troubles, it works now ;-) The mentioned MS 3D scan and kinect readiness wont work. It is supposed for the new kinect2 model, because of the new driver. Best you deinstall both. Even the drivers and SDKs. You need Kinect for ...

A point cloud is often derived by sampling. Each point represents an observation. Sometimes, a point cloud is turned into a surface by fitting triangles to the points in the form of an STL file. A raster is a 2D grid of pixels. It divides the area of an image into constant-sized little squares. Each of these squares has a value. A 3D raster is made of ...

There is scanning technology: either hardware or software (such software typically works from multiple 2D photographs). It has limitations, but is an active research area, and getting better all the time. "Autodesk 123D Catch" and "3-Sweep" are a couple examples. One tradeoff between automatic and manual is the complexity of the shape you need to duplicate. ...

I have also been looking for some free or paid software for doing 3D scanning and the closest I have found to something that might work is thishttp://wedidstuff.heavyimage.com/index.php/2013/07/12/open-source-photogrammetry-workflow/ But it isn't Structure from light (doesn't use a projector) If you want to stick with Structured Light then I would suggest ...

You can use a Kinect sensor for Xbox 360 OR Kinect sensor for Xbox One. That sensor allows you to get a true 3D surface with its SDK. You can connect these devices directly to your PC using USB (I have one). Even the Xbox One model, in its SDK, has an example that allows you export your captured mesh as STL files.

While I'm not sure what you mean by I want to scan a thing and modify it a little to see its effect. In general, a 3D scan typically results in a series of raw points. You'll need to convert the 3D point cloud into a Mesh before you can really do any solid modeling with it. Here are a few OpenSource programs that you could potentially use: MeshLab Blender ...

There is the capable but somewhat expensive Scan2CAD. Otherwise, if you're happy with outlines and not centre lines, scan b&w, aggressively clean up macules, mask off text, and then vectorize in potrace, autotrace, etc. Alternatively, load the bitmap at the correct resolution into a drawing package as a raster layer and draw the lines/objects you want ...

Given that LAS/LAZ is LiDAR point cloud data, there is a GIS tool called las2tin to convert these files to a triangle based mesh called Triangular irregular networks or TIN by the GIS community. Other GIS tools should be able to do the same, for example ArcGIS. Once you have the mesh, Google should be able to help you find a way to convert the TIN to an STL....

The Creaform EXAscan is according to the manufacturer a laser based machine. This means that it determines data points and their positions by some triangonometry done with a laser, 32.000 times a second, resulting in very high density point clouds. This demands a powerful program to work with. At some point, your company used Rapidform, which costs a ...

That's not Structured light, it is a camera. The camera makes a series of photos - one with each flash. Then, the photos are stitched to create a 3D model using a code that is similar to one I was shown in an informatics class in my uni once: the software identifies structures that are identical. By tracking the difference between the pictures, distances ...

Thus question is very close to being out of the scope of the questions encouraged on the 3D Printing SE site, but you have worked closely with Trish and Oscar to make it into less of a "recommend" question and more of a "how might I choose" question What to look for in a 3D scanner? You mentioned using the scanner for quality control. Lets start with ...

In an earlier comment you stated that you cannot take it apart. So without taking it apart, you could try to determine the profile the old-fashion way with a piece of cardboard and a short pencil, just cut the rough shape of the rod and place it onto the rod, then take the short pencil and draw the profile onto the cardboard with the pencil parallel to the ...

You need to disasemble the part and measure it with special equipment, a caliper can help but only as reference since the part has an angled shape. I recommend to use an optical comparator (base shadows) with this you can have X and Y data to calculate the angle and curves. If you want more precise measurements you can try an Optical Measurement Device (...

I don't know if this will work but BQ commercializes a Ciclops scanner and have some downloads in their webpage (https://www.bq.com/en/support/ciclop/support-sheet). There are different Horus and driver versions, maybe some will work for you(?). Hope it helps!

I have heard of similar scanning not using the electrical connecting but using the capacitance of the metal object to detect it. Capacitive Scanning works by detecting a metal object near the prob so the prob doesn't have to touch the object being scanned

So if the original manufacturer still exists, (which they appear to, and even list your scanner under 'legacy' products) your best chance of getting it working is going to be to contact them directly. Using proprietary hardware WITHOUT the associated proprietary software can range from merely tedious but possible, to outright impossible, depending on the ...

Here are some ways a program might indicate incompatibility: There is something in the code that is actually incompatible -- such as some Intel-only DSP instructions. They are using an Intel library or source code that is licensed only for use on Intel processors. They added a check to their code to be sure the processor was powerful enough to handle the ...

I believe a point cloud is just a collection of points, while voxels - "3D pixels" - define location and a cube area. They seem to be pretty equivalent mathematically.

I don't have enough reputation to comment. This is a short pointer to another webpage: https://www.sculpteo.com/blog/2016/01/20/turning-a-picture-into-a-3d-model/ It may be helpful.

It is not structured light. This uses a laser: https://hci.rwth-aachen.de/fabscan But it is completely open source software / open source hardware. See also here: https://www.thingiverse.com/thing:14198 https://www.youtube.com/watch?v=hBueeqDJ6rQ
