Security forces frequently utilize 2D architectural blueprint diagrams to plan operations within complex indoor environments. Nevertheless, understanding spatial information within a 2D blueprint under time constraints limits operational efficiency. This paper proposes an automated system that converts 2D blueprint diagrams into interactive 3D tactical training environments using a combination of deep learning and procedural generation techniques. The system employs a custom-trained model based on YOLOv8 to detect critical structural elements such as walls, doors, windows, staircases, and balconies within blueprint diagrams. The detected elements are then structured and integrated with a Unity-based engine to create an interactive 3D simulation environment in real time. The system also includes gamified mission scenarios, user interaction mechanisms, and performance analytics such as path efficiency, time efficiency, and task efficiency metrics. The entire system is implemented as an offline pipeline, ensuring efficient execution on conventional computing platforms. Experimental results demonstrate efficient detection performance and generation efficiency, thereby reducing time and cost compared to conventional physical model-based approaches. The proposed system presents a scalable solution for efficient tactical training environments.
Introduction
The text proposes a system for security force training that converts 2D architectural blueprints into interactive 3D tactical simulation environments.
It highlights a major problem in current training methods used by forces like NSG, ATS, RAF, and SWAT: they rely on 2D blueprints or expensive physical mock-ups, which are time-consuming, costly, hard to modify, and require heavy mental effort to visualize in 3D. Existing simulation and gamification tools improve training but are limited because they cannot automatically transform real scanned blueprints into usable 3D environments, especially under real-world constraints like poor image quality, offline use, and low hardware resources.
The proposed solution is a fully offline AI system that:
Uses a YOLOv8-based model to detect structural elements (walls, doors, windows, etc.) from scanned blueprints (JPG/PNG/PDF)
Converts detected 2D structures into procedural 3D environments using Unity
Generates interactive tactical simulations with features like movement, threat zones, and breach scenarios
Provides performance evaluation (path efficiency, time efficiency, mission analysis)
The system is designed for real-world deployment on regular laptops without internet or expensive equipment.
Conclusion
This paper has presented a system that can automatically convert a 2D architectural blueprint into a gamified 3D tactical simulation in under 5 seconds. A 0.902 mAP50 is achieved by a YOLOv8 model in door detection; a Flask API bridges the ML component and Unity 3D; a modular procedural generation pipeline in C# creates a 3D environment using solid geometry; and a web-based command dashboard serves all evaluator and trainee requirements. This system directly addresses SIH Problem Statement PS1773 (MHA/NSG) and eliminates the cost and time associated with physical mockup construction. Preliminary user testing has shown a significant improvement in path efficiency and door passage rate in three iterations of training, validating the pedagogical effectiveness of game-based rehearsal in security force training. Overall, the proposed system demonstrates a scalable, cost-effective, and real-time solution for modern tactical training using AI-driven simulation.
