DIY and Entry-Level 3D-Scanner Forum

I suggest to make use of a standard laser rangefinder, as you can buy it at your local hardware store.

Then, we need an interface to a computer. The company porcupine electronics sells a USB interface to the Fluke rangefinder

What do you think? Can we use this setup for the TOF 3D scanner?

Received the USB board from Porcupine Electronics.

Easy to install, works as promised

Hi Bernhard,

interesting ,

the guy on the video says the laser needs about half a second to acquire data on a moving target.

Is this the same laser you are planning to use ? If so, isn't half a second quite long for your purpose ?

thanks

Hugues

P.S.: i ordered my Carmine 1.09 and now looking for an online shop selling round 2.5 diopter lenses.

Yes, it is the same hardware. I know the delay is a problem, but I love this idea so much that I jast have to build it and test it

I was thinking of lowering the resolution for full room scans and to scan just small areas in high resolution.

If I would scan a room in full resolution, It would take 1600 steps in x-axis by 1600 steps in y-axis = 2,6 mil steps x 0,5 sec = 355.6 hours Which is, I guess, a little too long although the resolution would be OK.

If the resolution is 80 in x-axis and 80 in y-axis (6.400 pixels) the scan takeS still 3,6 hours. I think this setup is not yet usefull for scanning full rooms, but interesting for scanning certain areas of a room.

For scanning full rooms, I had the following idea:

I once tried to reverse-engineer the staricase in my house with Scenect from Faro.



You get a lot data points. If you try reverse engineer the saricase for example with Sketchup, most of these points are useless. You just need the corners and edges.

I was thinking of mounting a webcam on the laser that watches, If the laser beam is on a edge. If so, it makes a measurement.

This method should improve the speed a lot and result in a pointcloud that just has "interesting" pixels.

How much does this device cost and where can i get it? Thanks in advance for your quality time.
