Test paper image extraction method and device and terminal equipment

The invention discloses a test paper image extraction method and apparatus, and a terminal device. The method comprises the steps of collecting a test paper image of a to-be-extracted test paper; extracting a handwritten feature region image in the test paper image according to a pre-constructed test paper template; extracting and analyzing identity data information in the test paper image; and correspondingly matching the handwritten feature region image with the identity data information to obtain a test paper sample of the test paper to be extracted and a student handwritten number training sample. According to the method, the test paper image extraction can be realized with high precision and high accuracy, the answered test paper can be effectively utilized, the handwritten numbers in the student identity information are efficiently extracted as training samples, and a good training data basis is provided for a student handwritten number recognition model. 本发明公开了一种试卷图像提取方法、装置及终端设备，采集待提取试卷的试卷图像；根据预先构建的试卷模
