http://photosynth.net/view.aspx?cid=46FA3AD2-04A4-41A5-94AC-2498B206CF38 The headphones have almost no point cloud. What should I have done to make it better? Maybe it's the black color and shadow?
It's because the suject is too consistent in colour with little varying texture.
1. Take more images from a low angle. This will capture more portions of the headset that is lit up.
2. How do you know there isn't a pointcloud? Maybe the points are all black?
