Abstract
Disclosed are a plane coding target and an image splicing system and method applying the same. The plane coding target comprises a plurality of coding units distributed in an array, the coding unit comprises one central coding point, a plurality of normal coding points and at least one positioning point, and a positioning point distribution style of the positioning point is used for determining coordinates of the central coding point and the normal coding points in a coding unit coordinate system; and coding numerical value sequences of the coding units are different from each other and unique. The plane coding target can realize large-area coding and positioning functions, and the image splicing system applying the plane coding target can solve the problems of splicing error and error accumulation caused by an identification error of a splicing location, thus realizing large-range, high-precision and short-time two-dimensional image splicing.
