Photo editing software for dimensions

mwm5053

If you use images from street view, you only need to use 'Tape Measure' on a known dimension[like a postbox] to scale the whole model then fine adjust with 'FredoScale' or ScaleTool, 'MoveTool'

When I went to street view it was under construction and only the steel was up when they (Google camera) went by bummer huh

The below program is not free, around $39. I use this program because I get photos from afar that I need to turn into a model. This helps if you can get one or two items that you know the dimension.

Photogrammetric image rectification 1.0

Looking at this looks good doesn't say if the they have a ver. for Mac maybe you know

TGI3d Photoscan is suited to this type of work. I think it has a 30 day trial.

Option 1:

import image into autocad -- scale approximately
find a known dimension in the image and draw a line (e.g. a 200' long building)
a. on the image (on the 200' portion of building
b. a nearby line in model space the actual dimension (a 200' line approximately parallel to line in image)
select image, use align command, connecting line on image to scaled line
a. use only 2 points -- select to scale the image
Done!

Alternatively, my office uses BlueBeam (PDF editor alternative to acrobat), which has a calibration option where you select 2 points in an image and type in the distance between those. Then, all the measurement/editing commands will be scaled correctly.

you can do that in sketchup (and more easily imo)

-import image
-select the tape measure tool

click on first point of known length
click on second point of known length
type the actual dimension of known length
<return>
click 'yes' when asked if you want to resize the model..

(of course, this only works if the picture is a top/front/side etc view of the building.. if it's a perspective photo, you'll have to transform it first)

if the OP would kindly upload a picture he's working from (or if he'd rather not upload the exact pictures, at least a generic picture showing a similar viewpoint) then it'd be easier to advise on what needs to be done.

[edit] oh.. there's also that one plugin which will do this stuff.. you know, that one? i hope so because i forgot the name .. i'll try to find it though..

[edit2]
the plugin is called PhotoMatch:

(but i'm assuming this is the same thing mentioned in post#4 of this thread)

@ Jeff I think your right about all that and I did a little experimenting and going to stay on this coarse till I get it or just try to wing it.
It's the old I saw this photograph and I want to model that maybe over my head but I like a challenge I've done three or more homes and learning KT and at present Gimp. Ithink in Gimp you can change perspective not sure I'm using Google earth to get the basic idea of the layout of the place.

So this WIP is about Ocean House Watch Hill RI. Recently renovated.

@ Rich I downloaded TGI3d Photoscan for Mac and In an attept to unpack the file it said I didn't have SU 7 or 8 on my computer, funny will contact support

Now that I look at that photo it's a rendered photo. Here's one of the first jpegs I saw.

We will be addressing this issue in the upcoming releases. In the mean time you can create symbolic links from bash prompt for "/Library/Application Support/Google Sketchup 8" directory as in the example below:

sudo ln -s /Volumes/ExternalVolume/Library/Application\ Support/Google\ Sketchup\ 8 /Library/Application\ Support/Google\ Sketchup\ 8

Please do not hesitate to contact us from the Support page on our website as well. You'll find that we are in general very quick to respond to support inquiries from our website.
