Embodiment Construction
[0070] In the following, only some exemplary embodiments are briefly described. As those skilled in the art would realize, the described embodiments may be modified in various different ways, all without departing from the spirit or scope of the present application. Accordingly, the drawings and descriptions are to be regarded as illustrative in nature and not restrictive.
[0071] During the judgment process, the judgment application program sends the image of the question to be judged into the question type judgment model, also known as the layout analysis model or the text line detection model (the question type judgment model is a text detection model, which detects horizontal , vertical and off-style questions and frame them with text boxes (that is, get the coordinates of the text area), and get the layout analysis test results or text line test results. Such as Picture 1-1 As shown, the rectangular text box with dark thick lines represents the text area of each ques...

The present application proposes a model training method, a problem-judging method, device, equipment, and storage medium; wherein, the method includes: acquiring first training data, where the first training data includes a first initial text image and a corresponding first rotated text image Build a first initial model, the first initial model includes an untrained encoder and a deconvolution layer; Train the first initial model according to the first training data to obtain a first image rotation correction model; Build a second initial model, the first The second initial model includes the encoder in the first image rotation correction model; the second initial model is trained according to the first training data to obtain a text line detection model, and the text line detection model is used to detect the text in the first text image to be processed where the row is located. This can effectively improve or solve the problem of rotation of photographed images in the process of problem determination, and can improve the efficiency of model training and the accuracy of problem determination.
Description
technical field [0001] The present application relates to a data processing technology, and in particular to a model training method, a question judgment method and a device, equipment, and storage medium. Background technique [0002] Photo judging is an important application of artificial intelligence technology in the field of education. Usually, the process of taking pictures and judging the question may include: using a terminal device such as a mobile phone or a tablet computer to take a photo of the image of the question to be judged, and then upload the image of the question to be judged to the application program for taking photos and judging the question. The application program processes the image to be judged in multiple steps, and then outputs the result of the judgment. [0003] If the user uploads the picture instead of taking it from the front, but taking it at an angle, such as rotating the answering image 90 degrees or flipping the picture directly, in thi...
