Automatic mapping system having a mechanically and electronically controlled scanning means for providing faster response
Abstract
Abstract AN AUTOMATIC STEREOMAPPING SYSTEM INCORPORATING A MECHANICALLY AND ELECTRONICALLY CONTROLLED SCANNING ARRANGEMENT. IN ONE EMBODIMENT MEANS ARE PROVIDED FOR ELECTRONICALLY CONTROLLING THE POSITIONNG OF THE SCANNING MEANS IN ACCORDANCE WITH THE DETECTED TIME DISPLACEMENT OF THE SIGNALS OBTAINED AS A RESULT OF SCANNING EACH INCREMENTAL AREA SO AS TO ELECTRONICALLY COMPENSATE FOR ANY HEIGHT ERROR WITHOUT HAVING TO WAIT FOR MECHANICAL COMPENSATION. IN ANOTHER EMBODIMENT ELECTRONIC DIFFERENTIAL DELAY MEANS ARE USED TO ELIMATE ANY TIME DISPLACEMENT BETWEEN THE SIGNALS OBTAINED FROM SCANNING. IN THE FIRST EMBODIMENT A MEASURE OF HEIGHT IS OBTAINED IN RESPONSE TO THE MECHANICAL AND ELECTRONIC POSITIONS OF THE SCANNING MEANS, AND IN THE SECOND EMBODIMENT IS OBTAINED IN RESPONSE TO THE MECHANICAL POSITION OF THE SCANNING MEANS AND THE AMOUNT OF DIFFERENTIAL DELAY REQUIRED TO COMPENSATE FOR ANY TIME DISPLACEMENT BETWEEN THE SIGNALS OBTAINED FROM SCANNING.
