Architecture and design of a computerised stereogram generator for vision test

Area of Science:

• Ophthalmology
• Computer Vision
• Biomedical Engineering

Background:

• Accurate testing of the binocular vision system requires versatile visual stimuli.
• Existing methods for generating stereoscopic stimuli can be limited in flexibility and cost-effectiveness.

Purpose of the Study:

• To design and implement a microcomputer-based stereogram generator for creating diverse visual stimuli.
• To enhance the capabilities for testing binocular vision, eye movement, and computer vision applications.

Main Methods:

• Developed a microcomputer-based system for generating static and dynamic stereoscopic stereograms.
• Incorporated a 16/32-bit microprocessor for flexible control of stimulus parameters (size, shape, speed, disparity).
• Enabled generation of luminous stimuli on dark backgrounds with adjustable depth parameters.

Main Results:

• The system successfully generates varied stereoscopic and luminous visual stimuli.
• Parameters such as size, shape, speed, and disparity are controllable.
• The use of a 16/32-bit microprocessor ensures flexibility, speed, and compactness at a reduced cost.

Conclusions:

• The new stereogram generator offers a flexible, versatile, and cost-effective solution for binocular vision system testing.
• The system's applicability extends to eye movement measurement and computer vision research.
• This technology provides advanced capabilities for visual stimulus generation in research settings.
