The direction classifier is used in the scene where the image is not 0 degrees. In this scene, it is necessary to perform a correction operation on the text line detected in the picture. In the PaddleOCR system, The text line image obtained after text detection is sent to the recognition model after affine transformation.
At this time, only a 0 and 180 degree angle classification of the text is required, so the built-in PaddleOCR text angle classifier only supports 0 and 180 degree classification.
It is recommended to use fastdeploy.
