Geo-rectifying, ou les photos géoredresées

Jan 24, 2011 by Conan Parsons


OK. Been pulling my hair out.

I had a lovely collection of photos merged together from 4 georectified photos. Merged them fine, good location, good scale. turned of the labels for the georectified points to find SOMEONE'S LEG SMACK BANG IN THE MIDDLE OF THE NEW IMAGE.

So start again Schmigel.

OK that was paritally my fault, I could have ordered the photos differently before merging, BUT the way I had it had the best joins!

People, please I pray you, s'il te plaît, s'il vous plaît, por favor

Keep body apendages (of any description) out of the shot, especially if you're smack in the middle of the feature.

Make sure the tags are equal distances apart

Try and keep the tags as similar in altitude as possible

Keep the camera at the same altitude as much as possible

Keep the camera as level as possible

Try and keep 4 tags in the center of the shot as much as possible

4 tags in each photo, no more, no less. 5 is right out. 3 is also wrong, provided you continue to 4


If you can't read the photo number in the shot, do a sketch plan, or better still redo the photo if you've got time, adding more tags for closer shots.

 

When was the last time I saw geo rec photos that didn't need insane amounts of fudging? I shouldn't have to be this good at fudging!

 

Hmmmmm. fudge
