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.

This paper describes a kind of automatic test technology of the parameters used in a dual-CCD TV measure-system (TV -MS) .The TV -MS is the ground control equipment of the anti-tank missile and integrates the technologies of optical  machine and electronics. It is important and key component. The main technical parameters of the TV -MS are field of view  zero point  precision  sensitivity  anti-jamming ability  zooming time and focus time  etc. To insure the TV -MS satisfying the tactical and technical requirements and discover fault and reason  a fast and accurate equipment satisfying the test technical parameters of the TV -MS is urgently needed in manufacture and service. Firstly  the parameter test system converted optical signal to electronic signal  implemented automatic control of the invariant illumination of parallel pipeline output. Secondly  data and command delivering  displaying or printing are realized by using 80C196KB. The experiment result shows that the approach of automatic testing of the Parameters used in a dual-CCD TV -MS is successful and it can be used for all tests of the functions and parameters of the TV -MS. The main innovations are to realize the fast  veracious measure of technical parameters of the dual-CCD TV-MS  and integrate the technologies of optics  machineries and electronics. An advanced means is provided to judge the technical states  find malfunctions and discover the reasons in producing and maintaining process. The equipment suited for anti-tank missile systems is given.

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
