This project was created on 08/24/2021 and last updated 8 months ago.

Description

This scanner can scan small objects with fantastic accuracy. Its the "Mark 2" of my last Hackaday project, its slower because it requires several images, but it way more accurate.

The key components are now:
a). 2 cameras and 2 pies to make a stereo camera.
b). A projector to add structured light patterns to help the triangulation from the stereo camera.
c). A 2 axis turntable.
d). Custom written software to blend all the different views from the turntable together.
e). A huge amount of accuracy optimisation. Also careful use of memory so the high resolution uses the minimum RAM, and speed optimisations such as synchronising the cameras.

Its well calibrated too so the CAD files it produces are at precisely real world size.

Finally I'm proud of it now, so I've decided to launch it on Kickstarter to see if anyone would like one.

    Well, my decade long ambition to put something on Kickstarter has been satisfied.  Less than 2 days to run - any last orders from anyone?

Wow cool project. Can I use this printer for small appliances? I always break my countertop blender cups. It will help me write something for my users on https://blendersguide.com

  Are you sure? yes | no

Could you please post link to the kickstarter, this is something I have wanted at a reasonable price for a while

Hello, I am keen to support your project, it looks very pomising. But if I get one of your 1st series models on kickstarter, will I be able to use it for further development and improvement or is it a "black box", especially softwaresided?

  Are you sure? yes | no

Jolar wrote 09/03/2021 at 08:14 • point

Thanks.  The software with the Kickstarter package is a black box.  May I ask what modifications you had in mind?  Would it help to publish the usb communication protocol? That would allow you to control all the hardware, for example; operate the turntable, get syncronised image capture from the cameras, with your own choice of projected image sequence.

  Are you sure? yes | no
