TECHNICAL FIELD

[0001] The present application relates to the technical field of digital microscope interactive teaching, in particular to a microscopic interactive method and device for uploading information through an image acquisition module. BACKGROUND

[0002] The digital microscope interactive teaching system enables teachers to observe the microscope images of all students at any time during microscopic experimental classes and to perform various digital demonstrations, thereby achieving effective and lively interactive teaching between teachers and students. The digital microscope interactive teaching system has been widely applied and achieved good results. With the development of technology, the digital microscope interactive teaching system has undergone several generations of technical updates. From the initial analog image transmission to high-resolution digital image transmission, from complex non-standard transmission lines to standard RJ45 network transmission lines, to the latest wireless transmission technology.

[0003] For example, CN201320808463.1 (an interactive teaching device based on wireless transmission technology) avoids complex wiring and facilitates rapid setup and maintenance. From the student end without computer equipment to the student end with desktop computers, laptops, tablets, to the student's mobile terminal such as smartphones and portable tablets, etc.

[0004] For example, CN201711045166.4 (an intelligent digital interactive experimental teaching system based on multiple mobile terminals) directly uses the student's mobile phone as a display device, reducing the cost and facilitating maintenance. In order to increase the interactivity,

[0005] For example, CN201610405648.6 (a digital microscope based on networking communication and its interactive method) increases the cursor demonstration technology to improve the interaction efficiency between teachers and students. These improvements in technology bring students and teachers better experiences.

[0006] However, the above-mentioned solutions require the student end to be equipped with an external display in order to realize the interaction between the teacher and the student. This requires the student to frequently switch between the ocular lens observation and the display observation, which brings many adverse problems: when observing the image, the student pays too much attention to the information on the display and does not observe through the microscope ocular lens, and the student's hands-on operation ability cannot be effectively exercised and improved; the student may be bored with the experimental operation and operate the computer or mobile terminal to pass the time; in addition, the information marked by the student end on the display screen needs to be transmitted back to the teacher end, which requires special data processing and transmission channels, increasing the complexity of the system.

[0007] For example: CN109031643 A (an augmented reality microscope), CN110476101 A (an augmented reality microscope for pathology) and CN103034610 A (an AR augmented reality auxiliary gem observation teaching microscope), disclose a method of embedding a display screen into a microscope, which can observe the specimen under the ocular lens and see the annotations on the display screen at the same time, but there are still deficiencies, first, students need to leave the ocular lens when operating the microscope or annotating, which will also cause distraction; second, the annotation information or state information of the student end cannot be transmitted to the teacher end to realize real interaction.
