heat imaging and photoscan
« on: May 05, 2015, 02:04:22 PM »
hello
iam right now thinking about testing heat imaging with photoscan
i was looking at this device and was thinking about creating orthoimages
http://www.flir.com/instruments/content/?id=66732
i dont need much detailed geometry since the resolution is not great at all but i was wondering how the sensor works and if it could work with photoscan
anyone with expertise or sample images of that kind?
frank

resolution of this camera is only 80 x 60.
Far too low to get any serious results.
I did some test with a "top of the range" FLIR camare, having 640 x 480 pixels, and the results were very poor.
The best solution I found so far is to combine the flir camera with an optical one (high res), build the model from the optical images and apply the textures from the thermal images. To do so, you have to "warp" each thermal image on the corresponding optical one.

Hello frank,

I have the same kind of problems. I would like to know how you warp the RGB images with the IRT images from FLIR ?

thanks a lot,

Simon
