Abstract

The invention discloses a smart blackboard intelligent demonstration system and method based on coordinate positioning and touch screen positioning, and relates to the technical field of smart blackboard intelligent demonstration. An intelligent controller is in wireless communication connection with a stylus terminal of a stylus assembly; the stylus assembly comprises a telescopic rod, a capacitive stylus and a stylus terminal. The intelligent controller comprises a control unit, an image processing unit, an amplification analysis unit and a wireless transmission unit. A capacitance pen finger of an indicating pen assembly touches an intelligent touch screen and presses a magnifying button at the same time, and a control unit controls the intelligent touch screen to intelligently capture a screen capture image, obtain pen touch standard coordinates and transmit the pen touch standard coordinates to an image processing unit; the image processing unit obtains an amplified original image according to the screenshot image and the stroke coordinate segmentation, the amplification analysis unit amplifies the amplified original image according to the amplification proportion to obtain an amplified image, the amplification analysis unit controls the intelligent touch screen to display the amplified image, convenient and efficient display of teaching content is achieved, and the teaching quality is improved.

Description

technical field [0001] The invention belongs to the technical field of intelligent demonstration of a smart blackboard, and in particular relates to an intelligent demonstration system and method of a smart blackboard based on coordinate positioning and touch screen positioning. Background technique [0002] Most of the existing intelligent electronic blackboards are areas for handwriting and areas for display only. Areas that can be displayed intelligently can usually be enlarged intelligently to ensure that students at the back of the classroom can see clearly. Most of the existing smart blackboards are divided into smart display screens for smart teaching, and also include integrated handwriting boards for convenient teaching demonstrations for teachers. [0003] In actual use, although the smart display can display the pre-made courseware more clearly and conveniently; however, it cannot display the parts that you want to enlarge at any time as needed, which brings limi...
