What. I dont understand how you can make this claim. Guided bombs are NOT using CV with optical cameras. They use lasers, GPS, and other non "fancy" techniques.
I just don't get in what world you think military munitions are using CV for targeting bombs.
So I guess you've never heard of the AGM-62 Walleye, or anything else that came out of China Lake. Before you try backpedaling with some silly nonsense about how gating isn't real CV, maybe do a quick search through the journals that cover this stuff: aiaa would be a good start. Another path would be in relation to counter-counter-measures, and ground noise rejection for air-to-ground radar guided munitions. That stuff was deployed regularly all the way back to Vietnam.
The other poster mentions analog techniques used in contrast-tracking TV-guided munitions like the Walleye, but digital "CV-like" image/contour matching methods were used on the original Tomahawk cruise missile and the Pershing 2 missile to provide terrain-matching navigation and target guidance. GPS was neither sufficiently complete or accurate for strategic weapons in the late 1970s/early 1980s.
In more modern weapons, imaging IR sensors are well-established for terminal guidance on missiles like LRASM, JASSM, or NSM to distinguish targets from clutter and identify specific target features (specific parts of a ship, for example). Of course "traditional" "IR-homing" SAMs and AAMs now use imaging sensors (often with multiple modes like IR+UV) to distinguish between the target and decoys/jammers. Even your basic shoulder-fired anti-tank missile like Javelin requires some amount of CV to identify and track a moving target.
aka edge detection :) I don't remember if it was the Sidewinder or Walleye that eventually dropped in a CCD (or both), but I know that the Maverick (which is technically older than Walleye) got along without a CCD until the GWOT - when it finally upgraded. The Javelin actually beat Maverick in that regard, having a 64x64 sensor 10 years earlier - able to handle scaling and perspective change for the 2-d designated target pattern.
