Multi-camera inspection of underwater structures

This invention describes a method for inspecting underwater structures using an underwater robot equipped with at least two cameras. The robot collects stereo images, similar to how human eyes see, and then uses computer logic to identify matching elements and process these image pairs. This processing rectifies the images to create a simulated straight-on view of the structure, even if the robot is looking at it from an angle.

Why it matters: Filed before significant advancements in computational power and AI-driven computer vision algorithms. The core image processing steps, like identifying stereo cues and rectifying matched pairs, are now far more robust and efficient to implement on embedded systems suitable for underwater vehicles.
