Solution Overview
Problem
Current digital stereo microscopes require operation through binocular eyepieces, which can be difficult for inexperienced users and fail to provide effective stereo vision for naked eye display, especially due to synchronization challenges and the need for high operation technique.
Innovation Solution
A digital stereo microscope imaging system with two camera units, each with a lens and sensor, controlled by a microcontroller, synchronized by a main controller to generate and display RGB image data, allowing for stereo image synthesis and display without binocular eyepieces, using a synchronous synthesizer and stereoscopic display converter to produce a recognizable format for naked eye three-dimensional viewing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If two camera devices are used to capture stereo images synchronously, then stereo vision can be achieved, but synchronization is very difficult to achieve in practice
Solution Approach 1:
The patent merges the control of two camera devices into a single integrated system with a common controller that generates synchronized trigger signals for both cameras simultaneously, eliminating the need for separate manual coordination and achieving reliable synchronization
Solution Approach 2:
The patent introduces a common controller as an intermediary that generates and distributes trigger signals to both camera devices, acting as a mediator that coordinates their operation and ensures synchronous image capture without requiring direct camera-to-camera communication
2Ease of operation
If a convex lens is used to achieve stereo vision, then stereo image display can be obtained, but high operation technique is demanded and it is not suitable for naked eyes stereo image display
Solution Approach 1:
The patent replaces the mechanical optical system (convex lens) with an electronic display system that presents stereo images directly to the user's eyes, eliminating the need for manual focusing and alignment adjustments while making the system suitable for naked eye viewing
Solution Approach 2:
The patent creates a digital copy of the stereo image data from the camera sensors and presents it through a display device, allowing the stereo information to be reproduced in a format that is directly viewable by the human eye without requiring optical manipulation
3Ease of operation
If binocular eyepiece observation is used, then stereo microscope function is achieved, but it can be difficult to operate and even cannot observe any image for an inexperience person
Solution Approach 1:
The patent enables the system to automatically process and present stereo images through digital synthesis and display, eliminating the need for the user to manually adjust optical components or interpret complex optical paths, making the system self-sufficient and easy to operate
Solution Approach 2:
The patent segments the complex optical observation process into separate functional modules: image capture by cameras, digital processing by a controller, and display output, allowing each module to be independently optimized and controlled, thereby simplifying the overall operation
