ABSTRACT:
Operators of submerged remotely operated vehicles (R.O.V.)'s must typically view the subsea environment by use of a submerged television camera carried by the R.O.V. Often no part of the vehicle is visible to the operator to give him a natural indication of the direction in which the camera is facing with respect to the vehicle. The apparatus of the present invention generates an artificial "crosshair" on his television viewing screen representing a selected reference axis of the vehicle. This not only reduces directional disorientation of the operator but also gives him a line of sight, independent of camera direction, which he can use to establish the azimuth of subsea features with respect to the vehicle's compass.
