Script for extracting data from multiple points.

Post by JohnWayne »

Hello,

I have this project now where i need to measure the Z value of points on a floor for every 60 x 60 cm. And well, the area is quite large.
The only way i know to do this is Analysis -> measure point, and do them all manually.

Is there maybe a script to do this? Doesn't seem like a difficult script to make, if you know how to do it, that is.

Thanks,

Hi Brynjar,
did you have a look at the Grid Projection functionality? (Extract/Cloud menu).
Seems to me like this is what you are looking for!
Or Points on Grid if points need to be extracted on a point cloud!

Hi Gilles, thanks for your fast reply.

I have actually looked into that. points on grid etc. This have given me this result:
However the measures are all manually placed by clicking on each point (on the first picture). So getting the actuall points i need, I can do.
(This is only a test area, the actual floor is far larger.)

Export the area you want as e57 with a decimation at 60cm.

Import the .e57 in cloudcompare.

save it as a .txt

open the txt, the first values of each rows will be X,Y,Z coordinates, separated with a space, you can import that in excel if you want.
