Pave Strike Analysis - 1. Investigation of a Point Transfer Device.

摘要

This effort investigated the requirements for a point transfer device to support the Manual Photogrammetric Targeting System (PTS-M). The purpose of the point transfer device is to correlate a tactical image with a data base image and to make a physical mark on the data base image which precisely locates a target observed on the tactical image. This report defines the factors affecting the design of the instrument, itemizes the design specifications, surveys possible off-the-shelf equipment and suggests an instrument which can meet the requirements. The indicated design will allow an operator to view a tactical image and a data base image in superposition. The operator can change the scale, stretch,, direction of stretch, rotation and translation of both images until they are precisely registered. The operator aligns a reticle with the target, activates a marker and makes a mark on the data base which corresponds to the position of the target. A capacitive discharge system is used in the marking. A study was made to compare the repeatability of various viewing modes but the results were inconclusive and further experimentation was recommended.
