神经学家和工程师为外科医生开发了一种新的摄像系统，它可以看到眼睛看到的地方。这一创新装置利用眼球自发和反射性运动，通过视频视觉术以3-D的形式记录下来，然后在线计算，作为信号驱动相机在三个平面上的伺服电机：偏航、俯仰和滚动（图1）。它的主要目标是允许自由移动的用户将头戴式相机系统的光轴对准他/她在视野中自愿寻找的目标，而眼反射通过在头部和视觉场景运动和运动期间自然地反击相机的“凝视空间”来稳定任何图像抖动。人类眼运动控制的生物系统包含了这些功能，但到目前为止，还没有相机系统将用户的自由移动与图像稳定和对视觉环境的无限制探索结合起来。图1用户戴着头戴式设备，配有视频眼动仪。它们由两个横向连接的红外视频传感器和两个红外反射镜组成，每只眼睛前面一个，…
Neurologists and engineers have developed a new camera system for surgeons, which looks where the eyes look. This innovative device uses voluntary and reflexive eye movements, which are registered in 3-D by video-oculography and then computed online, as signals to drive the camera servo motors in three planes: yaw, pitch, and roll (fig 1). Its primary objective is to allow a freely mobile user to aim the optical axis of a head mounted camera system at the target(s) at which he/she is voluntarily looking in the visual field, while the ocular reflexes stabilise any image shaking by naturally counter rolling the “gaze in space” of the camera during head and visual scene movements and during locomotion. The biological system of the human ocular motor control incorporates these functions, but so far, no camera system has combined free user mobility with image stabilisation and unrestricted exploration of the visual surround. Figure 1 The user is wearing a head mounted device equipped with video eye trackers. They consist of two laterally attached infrared video sensors and two infrared mirrors, one in front of each eye, …
