Hello
Can you please make it easier to export an orthophoto to be used in cad software? i mean not simply export, but place them at the right place in the world. now its a bit a nightmare with the rcInfo file… when you compare at importing the new cross section… day and night…
an easier way would be the possibility to export the related reco box of the ortho as dxf
Hi, what CAD software are you using?
autocad, are you Ondrej CR on facebook capture reality arena? i tagged you on a post showing my issue. I know its already possible to import orthophoto, but not easy to figure out which axe is what between reality capture world, the orthophoto and autocad world ^^
In AutoCAD, there is an extension, which helps to georeference the orthos. It is called GeoRefImg. Are you using it?
ok i’ll have a look to that
is it working when you have only xyz info no gps position? and then its not a truly georef image? because i’m trying but doesnt seems to work, i have a warning "unsupported world file format (e-g. x-skew / y skew differ too much)
for a top view the tool work, but do not place the ortho at the same place than the point cloud
i dont know how much work it’s mean for you, for me i can’t do it but it’s look “simple”, but the ability to export the RC box as a dxf file would be huge
then you just have to figure out which face is it and paste the orthophoto on it
So you want to create an ortho from cut, not from the above?
In CAD, is your ortho as some kind of a background for drawing?
In this cases it is important to have a correct heights. In RealityCapture it is Z axis. In AutoCAD it will be Y axis, because it is only 2D system.
So, what you need to do is change these values in tfw file (I think last two vales are the coordinates of left upper corner of the ortho). One value is height and the other is for position. The height should be last in this case.
Also, are your models georeferenced?
my models are not georef, i’m using the grid export option in RC,
yes i want to create ortho like elevation / facade
so yes i can try to edit the pgw file and see if its work.
BUT i tried with an orthophoto from above (top view) and georef did scale it nicely but the position is totally wrong (i imported the point cloud on the side to be sure)
I’m sure about the position of the point cloud because when i import cross section as dxf, they do overlay super nicely.
Do you have set in both exports the same coordinate system? How much are these exports differ?
You can try to export the side ortho as Image (in coordinate system):
TWF file created from side view, Image:
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_
There are some strange coordinates for X axe, but the important thing in this case is the height (Y axe). You can change the X coordinate to 0 and the heights of the floors will be OK.
Also, about your request. The cross sections are 3D output, ortho is 2D output, so this is why it fits nicely on your point cloud.
Hello Ondrej,
Do you have any updates on the possibility to export the reconstruction box as dxf?
because georefimg is nice for importing aerial orthophotos (i mean top view) but just for the scale, and with uncorrect 10^x factor. for facades orthophotos, its useless… (well yes i could change the text file) you clearly have to admit that having the possibility to import the reconstruction box is waaaaaay simplier, since as you said yourself, rc box is 3D and will therefore be at the right place, rotation and size. just having to paste the orthophoto on the same side of the box…
Hello, there are no other info about this, yet.
Is this still in development now? This feature would be helpful.
I will add your vote to the feature request.
