I was really interested on this new application from my colleagues of the Computer Vision and Geometry Lab of ETH Zurich. They developed an application for smartphone that turns mobile-captured images into 3D point clouds. The user simply moves the phone around the object of interest aiming to maximize the common points between both images and a big enough parallax to obtain the relief. The point cloud is processed using Structure From Motion algorithms, with the aid of the internal sensors of the mobile phone.
I wish I could have a Beta tester version to show to my friend and colleagues on the go, when I’m trying to explain them the meaning of what a point cloud is 🙂
