Project Description
The Captured team wanted to find a more budget-friendly alternative to already available 3D scanners found on the market. We decided that, for small scale objects, we could design a system that could be built cheap and would provide a decent capture of the object.
A Raspberry Pi Camera, a line-laser, a Raspberry Pi for processing, a web page for user interaction and, of course, algorithms to create the 3D model.
Technical Description
Our 3D printer consists of a Raspberry Pi Camera, a line-laser and a Raspberry Pi for processing. We also created a web page for user interaction so the whole system could be controlled with ease.
The capture process is as follows: On a prefabricated platform, we assign a static point and align the camera and laser to that point. From there, when an object is placed, the scanner pulls the distance from the centre point to the outer layer of the object (that is why the laser is required – it can analyze outer bounds and determine size and shape). Our 360 platform uses a small motor to slowly but surely spin the object.
Technical Description
We scan the object, pull all the data, create a 3D model in our web-page and allow the user to inspect the object from any angle.
Furthermore, we also created a texturing script which will use the camera’s eye to capture the texture of the object and then apply it to the 3D representation of the object.
