Photo merge... HELP!!!
-
Photomerge is not the good tool for your project. It works fine on orthogonal objects.
For your problem, I will use the coastal navigation way to locate a point. We use alignments of land object like towers or mountains. In your aerial view, we can also use planar object like roads or river.- First search "vertical" alignments in the aerial view
- Next, report alignments on the SU model. They would intersect in a point (or nearly)
- Finally, the point of view would be on a vertical line over this intersection. Turn off the background model and place the aerial photo on background in the style setup panel.
Use the "place camera" tool on the intersection and use the Value Control Box to enter and test altitude and the Look Around tool too find the good direction and type angle of view in the VCB with the Zoom tool activated to find the right field of view. Don't use zoom tool directly on the model because it change the camera position (is not a real "zoom" tool, it's a "walk ahead" tool !).
If you have some data about the aerial photo (altitude, angle of view...), that will help you to find the right place and view.
Hope that can help you.

Well it should seeing each photo is generally taken with a different FOV.... Believe me, when i try to match the photo with the model it becomes severely distorted!!
That's because when using zoomm in Su it isn't really zoom, but moving the camera, which changes the perspective. Change the FOV to "scale" it, and the zoom to change perspective/position.Edit: That technique posted by @daredevil is a very good one
I often use a similar one, but haven't actually drawn those lines. Next time I will Using the Walk tool (or Look-Around) you can type in the eye altitude, or use the mouse+shift to change it.

Daredevil!

Cheers guys!! Gee some neat ideas there....!
Here's where I got to with it:
- Imported hi-res watermark image into the model
- Fiddled with FOV settings to manipulate the model and WHA-LA!!
That is a good process, daredevil!!
to you all; legends!! -
Wha-La?
Surely voilà
-
Only problem with bringing in a hi-res image as a watermark is that the export is only as good as SU exports your viewport... not good if you want to maintain pixel size.
-
Do the merge in Photoshop post pro mate!
-
I tried that but the problem is exporting a high enough image from SU.... When I exported and got rid of the background the edges were way too pixelated....
-
Drag it into layout with no background, convert to vector export hi res PNG from there!
-
Thanks smart-arse...... I'll try that!!

Nice job !!

Did you use anti-alias in SU?
Or didn't you use any feather selection in PS?
Or did you perhaps export as a compressed jpg? Not a good idea if you want to do any masking afterwards.Often it is better to export a big image without AA from SU and then scale it down smoothly in PS.
What exactly are we talking about here when you say "highres"?
BTW, there's no point in importing any highres images into SU, as they will be scaled down anyway, to what OpenGL can handle on your machine (max 2048px?) -

Mate I think Utiler is talking evry large images! SU can never match the output one can achieve going through the Layout option particularly if you export to PDF and then open that in Photoshop.

Hello guys
not exactly on the topic, but i couldnt find any tool that would work this problem out. Is it possible to zoom the window somehow (actual cutout of a view)? -
