Matched Photo Scaling Issue

I’m having a difficulty that I haven’t come across before, and maybe it’s the structure I’m working with, but it appears (as you can see with my screenshot) that I am having an issue with scaling the photo/model around the other, and no matter what I do, I can’t seem to fix the issue. I know for a fact that I have the correct measurements, and the lens I used on the camera was nothing special or out of the ordinary, so my question is, is there something anyone can see that might be affecting the end result of the matchup? Thanks in advance.

How are you going about trying to adjust the scale of the image? Or have you tried? If you share the SKP file, we can help you solve it quickly.


#3

This might be a dumb question but did you try scaling the model up by hovering over the blue (or maybe yellow) axis?


#4

yeah, if you hove over the blue (i think it works with the other axes too) it’ll let you make your model bigger or smaller


#5

The idea isn’t to scale the model to fit the photo. It’s to scale the photo to fit the model.


#6

If I’m not mistaken it moves the model closer to the image, it doesn’t scale anything.


#7

It changes the size of the photo relative to the model.

Do you just want the .skp file? or the image file as well? At this moment in time, all I really need to match up exactly (or close to exact) is the wall that says “Arvada Flour Mills.” Because no matter what I do, it always seems off and this is the first time I’ve dealt with this sort of issue in matching photos…


#9

Both would be handy. If you don’t want to share them publicly, send them by private message.


#10

I’ll just share them here, at least for the current time their availability to the public isn’t a concern. Thanks…

And because of their size, I’m just going to link to the files here:

Thanks!

Was your image cropped? Photomatch cannot get it right if the optical center and the midpoint of the photo do not match.

Did you model the building from actual measurements or from old drawings? Some features like the length of the eaves and perhaps the roof pitch of the lower part do not seem to match with the reality.
