In this paper a method that measures relatively positionrelationshipquickly and accurately between two vehicles both on a horizontal plane is introduced. When the linear CCD camera placed on the end of manipulator scans two point targets located on the other vehicle
by virtue of the spatial intersection principle and trigonometry theorem
the relative position relationship between the loading vehicles and launching ones can be gotten(i.e. the spatial coordinate parameters of x
y
z and the angle displacement ). At the same time the paper establishes that the measurement error of length is less than 1mm
by analysis of thee rror analysis and the simulation of computer. The angle displacement is less than 3
which satisfies the technical requests. So the vehicle orientation and loading missiles can be both done at the shortest time. It meets the demand of centralization between the measurement and execution. Forboth automatic transshipment and spatial position relationship measurement
the study is valuable. And the manipulator is measure device as well as executive one so that residual inherent error decreases according to identical reference principle. Therefore the measure precision can be improved greatly.

A method that measures relatively position relation between two vehicles fleetly and accurately that are both on a horizontal plane is proposed in the article. When manipulator rotates horizontally
that of angle is less than 26
the linear CCD vidicon that is on the end of manipulator on the loading vehicle scans two point targets that are on the launching vehicle
which satisfies technical requests. So the method is feasible. The research is not only significant for missile of automatic transshipment
and then we can utilize spatial intersection principle and trigonometry theorem to get relatively position relationship. I.e. the coordinate parameters: x
but also is valuable in theoretic research on method of measuring spatial position relationship.
y
z
. Error analysis and the simulation on computer validate: the measurement error of length is less than 0.84mm
