Scale bar on Ortho Photos

[jm1706]

It would be nice, if the model is scaled, that there be an option on the exportation of Orthographic images to include a scale bar. That way we can then scale the image in other software if needed without having to find the area that we scaled from or the GPS position (bit hard on a vertical wall). Importantly one of the most annoying processes that we have to do is take the image into autocad or corel, create the scale bar from scratch, just to then allow us to give the data to those we work for. If this could be done automatically in photoscan, then it will save us a lot of time and make the process more streamlined.

A more precise way to scale orthophotos in autocad is to make a note of the pixel size and image dimensions in the photoscan orthophoto export options, then scale the image in autocad using the length of the longest side of the image as a reference and setting it to pixel size * longest dimension in pixels.

*edit just noticed that was why you had to bring it into autocad in the first place... sorry!

Thanks for the suggestion. That is the way that I do it in AutoCAD but it would nice, as the model should already be at the correct size, that a simple scale bar be included somewhere on the exported image.

I have a similar problem and I would like to ask for your opinion. I save the orthophotos (scaled through markers) of the different projection planes and I insert them into Autocad. When I do that, two of the orthophotos have the same dimension and the two others not (I mean that my object is bigger in two of the orthophotos). Why is this happening and what I should do to fix it. Thanks a lot in advance!
