Test the design rules for your printer(s) (group project)
Design and 3D print an object (small, few cm) that could not be made subtractively
3D scan an object (and optionally print it)
Various 3D Scanning Technologies
Following are the two Interesting and Relative simple Technique to for 3D Scanning I have Explored based on a all the links refereed in the class.
1. Photogrammetry
WellThis is a Simple Technique as compared to Light Coding.
All We need is a good high Resolution Camera to take multiple photos.
They Way Photogrametry works is, we take multiple photo of an object from different angle around it and use a software to generate a 3d shape for the same.
Various algorithms are used within the softwares to achieve the same.
It gives you the best colour detail, however is not the most accurate for making precise measurements.
Following the are few softwares I came across.
AUTODESK RECAP Simplest to use its be the new Avatar of 123D Catch so alll the features of older software are upadted in the new one.
AGISOFT PHOTOSCAN Very professional but trial edition do not allow to save software
Its designed to do 3D Mapping of rooms and Object.
The Software Along with it works only in IPAD. Thus Together it is Relatively Costly.
THE PROCESS
3D Printing
I Went Ahead With The Microsoft Kinect Sensor and use the SKANECT Software to scan
This is how the Skanect Software looks like
The Body Option will scan an area of size 1x1x1 Meters it will allow some movement of object Kinect Has To Rotate Around The Person sitting or standing like Moon revolves around the Earth.
The Object will scan a smaller area.
The Room Option Will Scan things around the Kinect, It Kinect will Revolve at the Center.
This is the Major difference between this two option.
Half Room. will have 3 x3x 3 meter cube scan area.
Below is a Scan Result Once we scan it takes time to reconstruct
The Reconstruct option gives options to Close the Object if its open from below
I have Scanned my Friend Siddharth Arya (student Fabacademy)
What We see Below is the White path shows the motion of the Kinect sensor which it has traveled during the scanning.
last
Next I Exported the scan file in desired formate.
Note as the Skanect is not licences and I was using a Trial Verions of it It it not possible to export a hight quality.
The export quality goes down when we export from a trial verison
A less poligon model is exported.
Below is the example of Low-Poligon model. (Model with lesser details)
Learned how NOT to scan or say understood ways to Scan things and Buildings and People. Have enjoyed the Scanning the Most specially going out and scanning The building.
