DIY Laser levelling using webcam and laser level

[devmonkey]

Hi Joe
Hi All

I downloaded the next version that displays a graph of the measured points. And look how nice and linear the graph is! .05mm measurement steps on the dial indicator.



I ran it 3 times to check.

While testing I moved the light a tiny bit. I had to start again, The light source will have to be rigidly mounted on the platform or you will get errors.

Will the current software work with higher resolution cameras say 1080P? I realize there would be more number crunching for he processor.

Great result, would be interested to see what it looks like in 0.01mm steps. What does the residual chart look like? I can see your residuals are all less than one pixel which means your step size was very consistent. Also if you put in a scaling factor in the umPerPixel preference you will get your results in um, or tenths or whatever. I need to make these preference persist between runs.

At the moment the software asks the cam for a vga image, so it doesn't matter what the cam resolution is, I can make this more configurable.
