Abstract

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, 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, and then we can utilize spatial intersection principle and trigonometry theorem to get relatively position relationship. I.e. the coordinate parameters: x, y, z, α. Error analysis and the simulation on computer validate: the measurement error of length is less than ±0.84mm; that of angle is less than ±2'6'', which satisfies technical requests. So the method is feasible. The research is not only significant for missile of automatic transshipment, but also is valuable in theoretic research on method of measuring spatial position relationship.
