Sardauscan : opensource DIY 30$ laser scanner

Sardauscan is a open source Sub 30$ 3D laser scanner that you can easely print yourself. Even 12$ if you already have a hercule HD twist. I think we can say it's "the cheaper 3d scaner on earth"

Description

Sardauscan is a open source Sub 30$ 3D laser scanner that you can easely print yourself.

Even 12$ if you already have a hercule HD twist. I think we can say it's "the cheaper 3d scaner on earth"

you just need a arduino nano, 1 to 4 line laser and a micro geared stepper (28BYJ-48)
(see instruction for BOM)

no external power needed. just 2 free usb port on your pc : one for the webcam the other for the rest.

The software Is written in C# and allow you to compose your Scan task by drag and drop.

Recommended Process is composed from these scan
“Scan” => “IrQ filter” => “merge laser” (if you use more than one laser) => “Build Mesh by interpolation “ => “Save STL”.

But if you are not satisfied with the build-in processing task, or if you prefer use another heavy but powerful software to work with your point clouds like meslab or other,

you can just “Scan” => “Save Ply” and import them in your preferred application.

While the software come with a building support of the Sardauscan hardware, and usb camera. You can easely write your own Hardware proxy via plugins.

You can event build your own task to insert in your scan process.

Source Code : https://github.com/Sardau/Sardauscan

real time scan video :
postprocessing start @ 1:50, if you want to see the speed of post processing (smooth, mesh reconstruct, and stl generation )

i've adden a instructable to explain how to build, calibrate and use the sardauscan. any vote will be apreciated ;)

Materials and methods

- Bunch of M3 (16 and 20 mm)

- Bunch of M4 (12 ans 20 mm)

-1x chinese Arduino nano (chinese copy, 4$) http://www.befr.ebay.be/itm/NEW-Nano-V3-0-ATmega328-Controller-Board-5V-16M-CH340G-USB-Driver-For-Arduino-/141433274102?pt=AU_B_I_Electrical_Test_Equipment&hash=item20ee147ef6

- 1x chinese Stepper Motor and controler (5$) http://www.befr.ebay.be/itm/Uln2003-Stepper-Motor-Drive-Driver-Stepper-Motor-Controllers-5V-4-Phase-5-Line-/261743645463?pt=LH_DefaultDomain_3&hash=item3cf1231317

- 1-4x Line laser (2.5$ piece) http://www.befr.ebay.be/itm/251688838898?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1439.l2649

- 1x Hercule HD twist (15$) http://www.befr.ebay.be/itm/Hercules-HD-Twist-5-0-MP-720p-High-Definition-Mini-Web-Cam-Green-Edition-/381162889539?pt=LH_DefaultDomain_0&hash=item58bf142143
- 20x20 profile ( can be printed : for exemple http://www.thingiverse.com/thing:280318)

- optionnal 3x 4mm roller (0.3$ piece)

total 26.5$ (1 laser) to 35$ (4 lasers)

2020 lengths of my build (but you can use whatever you want, just make sure the camera can see all the scan area)
- 2x 140mm
- 1x 120mm
- 1x 250mm

you must install the accellstepper library in arduino to compile the firmware
https://github.com/adafruit/AccelStepper

what to print.
- 1 x arm_left.stl
- 1x box.stl
- 1x box_door.stl
- 1x box_arduino_clamp.stl
- 1x arm_right.stl
- 1x CORNER.stl
- 1X Camera_HOLDER_LOWER_PART.stl
- 1x MOTOR_MOUNT.stl
- 1 to 4 x laser_holder.stl
- 1x Camera_HOLDER_UPPER_PART.stl
- 1x center_axe_MINIMAL.stl OR 1x table_AXLE.stl
OPTIONAL
- 3x roller_baseV2.stl
- 1x calibration.stl

you can print 12x M4_tslot_nut.stl if you use 20x20 profile and you don't have any
