And i have solved the allign problem, now the model are perfect… thanks…
but there is a problem with a model coordinate… i don’t know why
The last question… i had generated an ortophoto but when i export and import in a cad software which is the correct scale?
how i reconpute a correct dimension?
The scale should be correct as you used the laser scan as reference, which is in meters
Yes, and for do this, i have to put laser scanner position locked, right?
Don’t have to. But then this should keep the original coordinate system and the alignment is not changed
- No changes in camera position and orientation allowed during alignment
ok…
and how i calculate the ortophoto real scale?
i have a facade the model are correct but the ortophoto is scaled, how i re-scale in a correct dimension?
thanks
Ortho should be in the size of the model, so it should be scaled correctly.
What are your settings there?
Is the TFW file created also with ortho?
So, it is created with tfw file (in your case jgw, as you exported jpg).
TFW file created from side view, Projected:
-0.0000000000 - rotation
0.1438256053 - X pixel resolution
0.1439776282 - Y pixel resolution
0.0000000000 - rotation
-128.9205612660 - X coordinate of upper right image corner
-1350524.4813268578 - Y coordinate of upper right image corner
To use the file in CAD, you should transform it into this format:
0.1438256053 - X pixel resolution
0.0000000000 - rotation
0.0000000000 - rotation
-0.1439776282 - Y pixel resolution
_-1350524.4813268578 - _X coordinate of upper right image corner
128.9205650291 - Y_ coordinate of upper right image corner_
Do you need 5 mm ortho resolution? Is the building approximately 8 m high?
Yes 5mm and around 8 meters…why?
but i cad where i put?
If the building is 8 m high, then it is scaled good (there is -8 m in your jgw file)
This file could be apply automatically in some software, but in AutoCAD you need to have installed plugin: https://www.cadstudio.cz/georefimg for example.
But you need to change the file according the example from previous message (change the lines)
Wooooow… you have solved all my problem…
fantastic…
thanks a lot
You’re welcome
Ondrei, how are you?
before i delete photoscan, i have another question.
it is possible to merge 2 component using a know control point?
i have a bad overlap beetwen laser and drone photo… but i have a know coordinate of cp…
can i rototranslate and scale a component drone via cp with a know coordinate of control point?
you andestrand?
this is my question and my problem…
in the first image i have a point cloud in my software and are display a reference point in a localsystem.
i exported a point and point cloud and i imported in RC, but the result was different…why?
RC change the coordinate system
What were your laser scan import settings? Did you choose the right coordinate system?
I choose, local coordinate
So it was like this:
The GCPs have the same coordinate system? Are the scans in local coordinate system? Maybe don’t use Locked in this case.
About your previous questions, it is possible to merge laser scans and images using control points. You just need to find these point on images and place them there. Then just realign project.
i have to put the cgp in the photo and laser, alright?
yes i used this, exact… yes is the same system coordinate…
this is a reason because the last project when i exported the model was shifted…you remember?
i have to put the cgp in the photo and laser, alright? - Yes, if you want to merge your datasets
this is a reason because the last project when i exported the model was shifted…you remember? - I remember, but this shouldn’t be the reason for movement. Is it possible to share your data with us?
