| Summary: | 碩士 === 國立海洋大學 === 機械與輪機工程學系 === 84 === The operation of a ROV(Remotely Operated Vehicle) relies
mainly on the videosignal taken by an on-board CCD camera.The
change of viewing angle of the camera is done by a servo
mechanism which is controlled by the operator using a knob.thus,
the operator has to spare a hand to change the camera angle
while he isengaged in manuvering ROV, which is inconvenient and
less efficient. More over,the video taken by one camera can only
provide a 2-D image. Therefore, the operator can not judge the
distance from it, which is a major drawback. To improve the
operation of ROV ,a camera servo-mechanism controller by HMD
(Head-Mounted Display) and the use of stereo-vision were
proposed in the research. A two-degree of freedom servo-
mechanism powered by dc motor was built, to trace the movement
of head, A linkage mechanism. A inclination sensor was forpitch
angle detection, and a potentiometer were used for yaw angle
detection. To achieve stereo-vision, two cameras were mounted
on the camera servo-mechanism,the live video signals are
transmitted to two LCD dispaly for creatingstereo-vision. The
parameters for were established. Through testing and experiment,
the camera servo-mechanism performs well when tracking head
movement and the stereo-vision display did improve the ability
of judging distance.
