General / estimate image quality
« on: March 26, 2014, 05:38:22 PM »
Hi,
Somebody know what exactly do Photoscan to define the image quality?
I did some tests with different textures and exposure parameters fixed. Results are better for a fine texture (sand than gravel) and always better for S size than L size of the picture. But this coefficient seems to be very variable according to exposure and the type of the object (for example, an aluminium paper will have a better coefficient in under exposure than in over exposure).
More over, I have a photo test with a quality coefficient of 1.06. I thought this coefficient varied between 0 and 1.
Someone can help me?
Jules.
