Abstract

The invention relates to a blackboard writing synchronization method. The method comprises the following steps: (1) finding a left position, a middle position and a right position above a blackboard,installing a small camera at each position, aligning the lens angle of each camera with the blackboard, selecting a shooting interval of 4-8 minutes, and clearly shooting current complete blackboard-writing information according to a set time interval; (2) synchronizing blackboard-writing information pictures shot by the camera to a cloud end through WiFi, performing sorting according to course classification and time sequence, and performing updating in real time at the cloud end; and (3) automatically copying the blackboard-writing information in the camera on a website through the cloud oran APP on a mobile phone so as to carry out learning work such as note arrangement after class.

Description

technical field [0001] The invention relates to the field of information recording and synchronization, and more specifically, relates to a blackboard writing synchronization method. Background technique [0002] In recent years, due to the popularization of smart phones, students are increasingly using mobile phones in more areas of life than communication, of which learning and life is one aspect. Although the blackboard writing recorder is convenient for students to record blackboard writing, it still has the defect that it is not convenient for students to obtain blackboard writing information from the blackboard writing recorder. Therefore, it is very important to synchronize the information recorded by the blackboard writing recorder for easy access. Contents of the invention [0003] In view of the above problems, the purpose of the present invention is to overcome the deficiencies of the prior art, and provide a method for synchronizing writing on the blackboard, ...
