Laser Scanner

Postby caver.adam » Dec 17, 2013 5:14 pm

Has anyone seen an work done to cobble together some cheaper options than a full scale Lidar? The cheapest Lidar solution i can find is around $30k. And most are considerably more.

I was particularly interested to see devices from Hokuyu which can operate easily to 30m and under ideal conditions to 60m. The accuracy is limited to approximately 5cm. They only scan horizontally and only to 270 degrees around, but if you mounted them to [relatively] cheap platform couldn't they be used repeatedly to get dimensions in more directions? At $6k plus a mounting platform it would be interesting to see what is possible.

Mainly just wondering how much work others have done to look at psuedo-DIY Lidar. One day the other Lidars will come down in price and we can just use them.

I wish I had their budget...

Actually, I kind of like the challenge of sticking to a lower budget. I'd rather that technology developed until all caves could be mapped with it. Although their mapping is pretty darn sweet.

I'm currently designing and build a laser scanner that works like this one: https://sites.google.com/site/todddanko ... ser_ranger
Should be able to build this fairly inexpensively. Especially if you used a rasberry pi ($35) and a cheap webcam ($15). The laser modules can be got for around $5. The rest of the electronics and gear would probably run another $10. So were talking around $60 and a lot of time :)

I'll be posting some details of my project at http://blog.bee-eee.com
