So i am digging this thread up again. I don't want to start more threads and the information within here is still useful.
I want to attempt thermal photogrammetry reconstruction.
What I got is a tripod setup and turntable. The idea is to set minimum and maximum temperature in the Thermal Camera+ app and then lock the palette. Disable the min and max range afterwards do you end up with black and white instead of blue and red, which looks horrible with superresolution.
But I now need ideas for targets. Simply geometry, and high thermal dynamic range. Should be warmer then room temperature becuase my backdrop is just paper. Non reflective. Rather small, like max 150mmx150mmx150mm.
A cup of tee is an option, but is loses its temperature over time, so I need to be fast with my capture. As I plan to have 3 passes and turn the table by about 30° each step.
Soldering iron is too hot I think; It will just be blown out on my camera, and it's reflective.
I got a stage lamp that heats up, it's painted black so it's less reflective, maybe with some emissivity tweaks it can look good.
Please give me some suggestions. I mainly plan to take images with the custom render and a greyscale palette, but will also save radiometric jpegs and use Palette generator to set top and bottom ends and scale the histogram linear to export .pngs.
For software I will use VisualSFM and Autodesk ReCap Photo, cloud based.
