Method, device, apparatus and storage medium for processing blackboard writing image

The invention relates to a blackboard writing image processing method, a device, a device and a storage medium. The method comprises the following steps of: obtaining a blackboard writing image; carrying out gray processing on the blackboard writing image to obtain a gray image corresponding to the blackboard writing image; determining a first template image according to the gray-scale image and apreset gray-scale threshold; using a preset image processing method, the first template image and the preset image are processed to obtain a target blackboard writing image. In the blackboard writingimage processing method provided by the invention, the process of image data processing is simple, so that a large amount of terminal resources are not occupied, the processing time of a large amountof image data is saved, and the Catton phenomenon during picture playing is not easy to be caused. 本发明涉及种板书图像的处理方法、装置、设备及存储介质。该方法包括：获取板书图像；对所述板书图像进行灰度处理，获取所述板书图像对应的灰度图像；根据所述灰度图像和预设灰度阈值，确定第模板图像；采用预设的图像处理方法，对所述第模板图像与预设图像进行处理，得到目
