DIY Laser levelling using webcam and laser level

[devmonkey]

Hi Jazz

Well, i think we arrived at the point were the cheap cam +software used as a levelling sensor proved it is very good.

The new problem is the lens you use to spread the laser into a beam....

The projected line can be a non straight because of the deviations caused by the optics used to spread the beam.


Does that summarize it?

I plan to use it to level check Y and X 1 axis at a time in the axial direction where the line is straight. First for vertical then horizontal deviation. maybe the diagonal

After that i will see...

Not sure how to do Z yet.

My laser crosshair only aligns in 1 orientation. +/- 0.8 mm /mtr out of plum
according to factory spec.

So Z could stil be non straight


Grtz Bert.

Hi Bert,

The optics should be better than that even for a crap laser, usually the quoted accuracy is out of plum as you say, this is error relative to whatever reference the laser is bolted to, i.e. a pendulum usually, this is not usually a measure of how 'straight' the projected line is.

Cheers, Joe
