Multivyvarieteter av Rolling-Shutter-Kameror
This study looks at the rolling shutter camera model and how pictures taken by moving cameras of this model can be used in 3D reconstruction. Unlike how the widely used pinhole camera model takes the entire picture in one go, a rolling shutter camera ...
