Therefore, in order to improve the positioning accuracy, on the basis of trilateral positioning calculation principle, this paper introduces a method of positioning by introducing multiple reflectors, which can reduce the influence of system error on the positioning results. The so-called use of multiple reflectors, that is, AGV laser scanner rotation, can measure n reflectors 1, 2, 3 i… n. Using the static matching and dynamic matching methods of reflecting plates described in this chapter, the coordinates of the matching reflector list in the global coordinate system xoy are (x1, Y1), (X2, Y2) (Xi,Yi)… (xn, yn), n circles can be produced, and the position of AGV must be at the intersection of these circles<br>
