3、实时性是一个难以解决的重要问题。图像采集速度较低以及图像处理需要较长时间给系统带来明显的时滞，此外视觉信息的引入也明显增大了系统的计算量，例如计算图像雅可比矩阵、估计深度信息等等。图像处理速度是影响视觉系统实时性的主要瓶颈之一。

4、稳定性是所有控制系统首先考虑的问题，对于视觉控制系统，无论是基于位置、基于图像或者混合的视觉伺服方法都面临着如下问题：当初始点远离目标点时，如何保证系统的稳定性，即增大稳定区域和保证全局收敛；为了避免伺服失败，如何保证特征点始终处在视场内。

机器人视觉应当进一步研究的问题

1、图像特征的选择问题。

视觉伺服的性能密切依赖于所用的图像特征，特征的选择不仅要考虑识别的指标，还要考虑控制指标。从控制的观点看，用冗余特征可抑制噪声的影响，提高视觉伺服的性能，但又会给图像处理增加难度。因此如何选择性能 的特征，如何处理特征以及如何评价特征，都是需要进一步研究的问题。针对任务有时可能需要从一套特征切换到另一套，可以考虑把全局特征与局部特征结合起来。
