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.   Application of linear CCD for position measurement (EI CONFERENCE) 会议论文 ICO20: Optical Devices and Instruments, August 21, 2005 - August 26, 2005, Changchun, China Fu Y.; Liu L.; Wu K.-Y. 收藏  |  浏览/下载：17/0  |  提交时间：2013/03/25 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
