Title: Vector coordinates center project to txt
Post by: AndreaR70 on June 01, 2021, 03:16:06 PM

Hi all,

Excuse me for the question but i'm not very able with python!

I got the vector coordinate (UTM32) with this part of scipt converted in string:

Code: [Select]

doc = Metashape.app.document
chunk = doc.chunk
cor = str (chunk.crs.project (chunk.transform.matrix.mulp (chunk.region.center)))
print (cor)
I can see in output this:
Vector ([519249.1224876235, 5040138.770116413, 131.04726993710898])

Now i would to transform the output without the characters "Vector (]" decimals and commas to this exactly string:

519249.000 5040138.000 131.000

and finally print the result to txt file

Anyone can help me to complete the script

Thanks in advanced

Andrea

you can try this code:

Code: [Select]

doc = Metashape.app.document
import math
chunk = doc.chunk
c = chunk.crs.project (chunk.transform.matrix.mulp (chunk.region.center))
print(math.floor(c.x),math.floor(c.y),math.floor(c.z))
should get following output:
519249 5040138 131

I think you can also use the following approach:

Code: [Select]

cor = chunk.crs.project (chunk.transform.matrix.mulp (chunk.region.center))
print("{:.0f} {:.0f} {:.0f}".format(cor.x, cor.y, cor.z))

Thanks Paulo and Alexey

It works with both scripts!
There is a way to add .000 for any vector coordinates for have this output?

519249.000 5040138.000 131.000

Hello Andrea,

If you need to add just ".000" regardless the input, then just add these symbols to the output line:

Code: [Select]

print("{:.0f}.000 {:.0f}.000 {:.0f}.000".format(cor.x, cor.y, cor.z))
