Voyis is unveiling Deep Vision Optics, a cutting-edge optical system designed to enhance image clarity and sharpness in subsea environments, compatible with both the Discovery Vision and Observer Imaging Systems.
Underwater cameras face a significant challenge in maintaining focus across their entire field of view and working range due to the water medium. Traditional dome viewports affect image formation and focus, leading to degraded image sharpness at the periphery. They also reduce the depth-of-field of the camera, meaning both close-up and far away targets cannot both have optimal sharpness. The result is image blur, reduced feature tracking accuracy, and inconsistencies in photogrammetry-based mapping applications.
To address these fundamental imaging issues, Voyis has developed Deep Vision Optics, integrating an advanced corrective optical design with three key objectives:
- Eliminate Corner Image Blur: By optically correcting for the effects of the dome viewport and water medium, the system ensures nearly equal sharpness across the entire field of view, allowing for full-sensor utilization.
- Enhance Overall Sharpness: The new optical system removes distortions caused by the water medium, improving clarity not just in the corners, but at the center as well.
- Expand Depth of Field: With customized optical engineering, Deep Vision Optics enables clear imaging of both nearby and distant objects, crucial for precision inspections and wide-area surveys.
These enhancements improve field-of-view utilization, situational awareness, and visual survey capabilities for ROVs and AUVs. Improved sharpness supports accurate machine learning analysis, while enhanced corner detail and depth of field improve the stability and efficiency of photogrammetry and VSLAM processes.
Deep Vision Optics represents a substantial advancement in underwater imaging technology, equipping operators to perform more precise, efficient, and automated subsea inspections. Voyis continues to push the boundaries of underwater vision, capturing every detail beneath the surface with exceptional clarity.
