Commandtolineofsight

Commandtolineofsight is a term used to describe a framework for translating a command into a line‑of‑sight constraint within autonomous systems, robotics, and simulated environments. It treats line of sight as a programmable resource that can be maintained, restored, or exchanged through control and sensing actions.

Etymology and scope: The compounding of "command," "line of sight," and "LoS" reflects the idea of commanding a system to preserve visual contact with a target or object of interest. The term is informal and appears in technical discussions, design documents, and some research explorations focusing on visual maintenance and sensor-driven navigation.

Principles and methods: Implementations typically include a translation layer that converts user or system commands into constraints on the agent's pose and camera orientation. LoS geometry is modeled via vectors and angles relative to the target, and constraint-based or model-predictive control is used to keep the target within a designated corridor of the field of view. Feedback from vision modules, sensor fusion, and obstacle avoidance are integrated to adapt to movement, occlusions, and latency.

Applications: In robotics and drones, commandtolineofsight supports surveillance, following, and maneuvering while maintaining target visibility. In video games and simulations, it helps NPCs stay visually coherent with players or objectives. In cinematography and automated cameras, it can govern pan-tilt systems to continuously frame a subject.

Limitations and considerations: The approach adds computational overhead and depends on reliable sensor data. Dynamic obstructions, rapid maneuvers, and latency can cause LoS loss, requiring fallback behaviors and robust estimation.
