Real-Time Game Terrain Scanner

I play a war-strategy title on PC and need a lightweight utility that can sit in the background, watch the game map round-the-clock, and instantly flag any change in terrain colour. The moment such a shift is spotted, the program must output the exact location in a latitude/longitude format (the game already exposes those coordinates, so you can pull or calculate them).

A few details to guide development
• Runs unattended 24/7 without draining resources or triggering anti-cheat alarms.
• Works from live screen capture or memory read—whatever is safest and most reliable for this game.
• Change detection must be fast enough to ping me before the tactical advantage is lost; near-real-time is ideal.
• Alerts can be as simple as a console line, log file, or small popup, provided the lat/long pair is clearly shown and timestamped.
• I’m fine with OpenCV, Python, C++, or another proven stack, as long as setup is straightforward.

Deliverables once we’re done
1. The compiled tool plus full source code
2. Brief read-me for install, config, and how to adjust colour thresholds
3. A short video or GIF demonstrating it catching a terrain-colour change and printing the coordinates

If this sounds doable, tell me how you plan to tackle continuous capture and noise filtering, and roughly how long you’ll need to put a first prototype in my hands.
