Efficient Tracking of 3D Objects Using Multiple Orthogonal Cameras
Enrique Muñoz, José M. Buenaposada, Luis Baumela · 2008
We introduce a multi-view direct procedure for efficiently tracking 3D objects. It is an extension of Hager and Belhumeur’s factorisation approach to the case of three-dimensional objects and multi-camera setup. By tracking a 3-D object we mean to estimate the pose and location of the object through a video sequence. A novel parameterisation of the object texture allow us to compute the Jacobian that emerges in the minimisation in a way it has a large constant part. The pixels viewed by each camera determine the rows of the Jacobian used for tracking. We perform qualitative and quantitative experiments confirming the validity of the approach.
