I have solution.
obj_1 --> base mesh
obj_2 --> target mesh
obj_3 --> mesh reveiver

# Maya variable
object_space = OpenMaya.MSpace.kObject
world_space = OpenMaya.MSpace.kWorld
# Maya node
obj_1 = pmc.selected()[0]
obj_2 = pmc.selected()[1]
obj_3 = pmc.selected()[2]
# Maya MFn
mfn_obj_1 = obj_1.__apimfn__()
mfn_obj_2 = obj_2.__apimfn__()
mfn_obj_3 = obj_3.__apimfn__()
# Points
points_1 = OpenMaya.MPointArray()
mfn_obj_1.getPoints(points_1, object_space)
points_2 = OpenMaya.MPointArray()
mfn_obj_2.getPoints(points_2, object_space)
points_3 = OpenMaya.MPointArray()
mfn_obj_3.getPoints(points_3, object_space)
# Normals
normals_1 = OpenMaya.MFloatVectorArray()
mfn_obj_1.getVertexNormals(False, normals_1, world_space)
normals_2 = OpenMaya.MFloatVectorArray()
mfn_obj_1.getVertexNormals(False, normals_2, world_space)
normals_3 = OpenMaya.MFloatVectorArray()
mfn_obj_1.getVertexNormals(False, normals_3, world_space)
# Offset
for idx in xrange(points_1.length()):
offset_point = points_2[idx] - points_1[idx]
offset_normal = offset_point.normal() - OpenMaya.MVector(normals_1[idx])
final_normal = OpenMaya.MVector(normals_3[idx]) + offset_normal
final_point = points_3[idx] + (final_normal * offset_point.length())
mfn_obj_3.setPoint(idx, OpenMaya.MPoint(final_point), object_space)

With this script I move the points offset relative to the normal.
I tried on my node but I still encounter some problems.
Thanks for your reply. I post python node when is finish
