             abstract = "In this paper we propose a visual estimation algorithm to aid the 
                         guidance system of an unmanned aerial vehicle (UAV). Specifically, 
                         we are considering a glider UAV trying to reach a target zone. 
                         Given that the UAV is falling fast, the scale of the images 
                         captured by the on-board camera grows. The vehicle dynamics and 
                         the control algorithm cause fast changes in the region seen by the 
                         camera and in the way it projects to the image plane. We propose 
                         an algorithm based on projective transformations to estimate the 
                         target coordinate during the flight trajectory. The proposed 
                         vision algorithm provides accurate position information allowing 
                         the control system to guide the UAV to the target zone. 
                         Simulations have shown the accuracy of the vision algorithm and 
                         its usefulness in the considered application.",
