Suggestions on Point Cloud fusion I am trying to fuse point clouds into one. These Point clouds are acquired from multiple cameras. Below is the detailed information about setup-

Three Kinect v2 sensors are mounted on tripods in such a way that they are making 120 degree angle from each other in a horizontal plane. Hence one can assume that these Kinect sensors are kept in the circumference of a sphere and pointing towards the center of the sphere. All three Kinect sensors are tilted vertically downwards approximately 30 degrees. The object which is being scanned is kept inside the sphere and visible from all Kinect sensors.

I am able to acquire three point clouds simultaneously from these sensors. Now I want to fuse three clouds to make 1 compete cloud.

What algorithm would I use for this?
You'll probably want to use a method for point cloud registration, also known as point set registration or point cloud alignment.  See, e.g., https://en.wikipedia.org/wiki/Point_set_registration.  RANSAC-like methods may also be useful.
