OBJECT PROJECTION METHOD AND OBJECT PROJECTION SYSYTEM

摘要

An object projection method includes: acquiring the three-dimensional coordinates corresponding to the matching point-pair (P0 and P1) of the object in the first video camera (21) and the second video camera (22); acquiring the affine projection matrix of the third video camera (32); calculating the theoretical barycentric coordinates of the object in the third video camera (32); calculating the theoretical projection size of the object in the third video camera (32); acquiring the actual barycentric coordinates of the projection of the object in the third video camera (32); acquiring the actual projection size of the object in the third video camera (32); and judging whether the three-dimensional coordinates corresponding to the matching point-pair (P0 and P1) is right or not. An object projection system using the method is also provided.
