Have a look at this video, this is DIY 3D Scanner https://www.youtube.com/watch?v=-qeD2__yK4c
I want to make some thing like that, but the difference is that the SharpIR sensor this guy uses is of very short range and my box in which this setup will present is big in size ( The Box is made of Ceramic).
There are some other SharpIR sensor which works at higher ranges as well, so i purchased this one GP2Y0A21 which have a range from 10cm to 80cm and i think this is sufficient range for my box.
Another difference is that, in the above video the object under scan rotates, while in my case i can't rotate the object (must condition can't change this), so I think, i need to use multiple lead screw assemblies, probably placed at diagonally opposite position, to do the same thing this guy has done.
For object (non-living or dead), again it can be anything that can be easily fitted inside the box which i am using.
So what i am thinking, to attach SharpIR sensor on a servo motor (servo motor will rotate from 0-90 degree for a particular height) and then attach this setup on Lead Screw assembly connected on Stepper Motor ( used for upward and downward direction movement).
By using this setup, i will get boundary of object for particular height of sensor, and then in PC, MATLAB will be used to plot the points to get the 3D shape of the object.
This is what i have thought and i am working on it, but after purchasing SharpIR sensor and measuring distance with that sensor i got lots of fluctuations in readings.
So i am reconsidering my approach, and asking for any other solution or any modification in this approach to get better results.
