Being able to have a 3D scanner at your disposal is something very interesting. Especially if you must regularly reproduce and print organic models, since drawing them can be a real nightmare.
A 3D scanner allows you to digitally capture the shape of any physical object, either using laser light or by photogrammetry. Basically you will create a point cloud made up of a set of vertices in a three-dimensional coordinate system (X, Y and Z). This will precisely form the outer surface of the object in question.
Today in 3DWork.io, I desire to show you an interesting way of how to build a 3D scanner with Arduino and photogrammetry. The only thing you will need is an Arduino UNO board, a 3D printer and some extra components, in this way you can prepare your own inexpensive and fully functional 3D scanner.
So let’s get to it …
Its operation is based on photogrammetry, a technique used by some 3D scanners to generate 3D objects from photographs taken on a model. It would actually be something like “measuring” photos, if it could be called that 🙂
This 3D scanner has been made by the user Bribro12 , and is a new and improved version of a previous existing design of yours on Thingiverse, but this time fully automated and with Bluetooth connectivity to smartphones.
The design presented by Bribro12 is not just another turntable as it might seem. This 3D scanner captures 360º photos of the object with a mobile phone connected to Bluetooth, all managed by a Bluetooth remote control that makes small advances in the platform.
It also allows us to define the number of photos to take, from 2 to 200, simply configuring from the same Arduino program. You can then convert all these photos into a 3D model using any available photogrammetry software, such as Autodesk Recap Photo.
It also offers us the possibility of using it to take photos or cinematographic shots of objects by setting the rotation of the platform at a certain speed. This can vary between 1RPM and 17RPM, which are the speeds of the stepper motor.
A third option would allow us to manually control the turntable, being able to bring it to the desired position and at the preferred speed. As you can see, it is a fairly complete application.
In the video you can see the complete process of the design and construction of the turntable, the servo drive for the advance of the platform and much more. The truth is that it is a very interesting project, everything must be said.
This is a list with the components that appears in today’s article. It is my duty to inform you that they are affiliate links to different internet online stores.
If by chance you use them, the price of the product will be the same as if you access them regularly. And 3DWork will have a small commission that will help maintain and give continuity to this website.
