摘要: 提出主动观察者利用摄象机旋转,凝视并跟踪环境点使视场中心保持固定,能提供求解 问题所需的许多有用信息,从而缩减待解问题的维数及运动参数数目,把不适定问题转变为适定 问题,大大简化计算的复杂性,有效地进行3-D运动估计、自运动复原及TTC的计算.Abstract: This paper proposes an algorithm for fixation and tracking and gaze control through camera rotation. An active observer with ability to control its gaze and keep an environmental feature stationary on its image plane can thus transform some ill-posed problems into well-posed problems. Problems of motion estimation, egomotion recovery, and estimation of time to collision can be solved very efficiently due to reduced dimensions, less motion parameters, and absence of complicated computation.
