TimetoCollision
TimetoCollision, often written as Time-to-Collision (TTC), is a metric used in robotics, computer vision, and automated systems to estimate the time remaining before two moving objects would collide if their current velocities continue unchanged.
Calculation typically relies on relative position and velocity. Let r be the relative position vector from
Interpretation of TTC hinges on its assumptions. It reflects instantaneous motion and assumes velocity and direction
Applications and limitations include widespread use in autonomous driving, aviation collision avoidance, robotics, and surveillance. Limitations
