Abstract

We propose a software-based minimum-time vergence control scheme (MTVCS) for a parallel-axis stereoscopic camera (PASC). First, a global horizontal disparity is estimated by using modified binocular energy models and transformed stereoscopic images via Radon Transform with a specified angle parameter. Second, with the estimated global disparity, the actual disparity command is derived through a nonlinear function such that the resulting horizontal disparity is equal to the command exactly with the control in a fastest time interval. Through experimental results, we will show that the proposed MTVCS achieves better tracking and regulating performances than those of the previous scheme.
