Problems solved by technology

At present, the carrier images captured are all images of the user’s finger reading. Fingers (palms, pens, etc.) will inevitably block part of the valid test data, resulting in partial data loss, affecting OCR recognition and test question search based on the recognized content. The matching degree, resulting in a low rate of original test questions that are finally pushed to users

Abstract

The embodiment of the invention discloses a method, a device, an electronic device and a storage medium for taking pictures of test questions to prevent finger occlusion. The method includes: when the electronic device is in a finger-reading scene, sending an interactive instruction so that the image acquisition device is aimed at the carrier and the light emitted by the finger-reading device falls on the carrier; Take pictures to obtain the initial image; obtain the text outline of each topic in the initial image, and identify the position of the light; determine the target image according to the text outline and position; perform OCR recognition on the target image, and use the recognition result to search for matching in the database test questions. By implementing the embodiment of the present invention, it is possible to completely avoid the loss of recognition content caused by the finger covering the content of the test question in the finger-reading scene, thereby improving the integrity of the recognition content of the cropped test picture, further increasing the rate of pushing the original question of the user's test question, and improving the learning efficiency of the user. Interactive experience.

Description

technical field [0001] The present invention relates to the technical field of intelligent terminals, in particular to a method, device, electronic equipment and storage medium for taking pictures of test questions to prevent finger occlusion. Background technique [0002] Most of the current electronic teaching aids have finger-reading scenes. The existing finger-reading scene means that when the user points to a carrier such as a book, exercise book or test paper with his finger, the teaching aid will take a photo of the carrier through the image acquisition device. And identify the position of the finger, so as to determine the user's intention according to the finger position, and then obtain the image corresponding to the user's intention, which is used for original topic search and so on. At present, the carrier images captured are all images of the user’s finger reading. Fingers (palms, pens, etc.) will inevitably block part of the valid test data, resulting in partia...
