python3中的opencv确实存在薄板样条。您可以使用帮助功能来获取有关存在哪些功能以及如何使用它们的更多信息，如下所示：

>>> help(cv2.createThinPlateSplineShapeTransformer()) ## () braces matter !!
Help on ThinPlateSplineShapeTransformer object:

class ThinPlateSplineShapeTransformer(ShapeTransformer)
|  Method resolution order:
|      ThinPlateSplineShapeTransformer
|      ShapeTransformer
|      Algorithm
|      builtins.object

|  __new__(*args, **kwargs) from builtins.type
|      Create and return a new object.  See help(type) for accurate 
signature.

|      Return repr(self).
