Automatic Camera Pose Recognition in Planar View Scenarios

The main goal of this paper is to recognize automatically camera pose from a single image of a planar view scenario. We apply this technique to sport event scenarios using as information the white lines/circles dividing the different parts of the sport court. Using these court primitives we define a loss function that we minimize to obtain the best perspective transformation (homography) matching the actual sport court with its projection in the image. From such homography we recover the camera pose (position and orientation in the 3D space). We present numerical experiments in simulated and real sport scenarios.
