1. An anti-collision system for an aircraft being towed by a tow tug, comprising:
wherein the system is disposed on the tow tug and comprises a sensor data processing unit configured to process data received from a plurality of sensors installed on the tow tug to detect objects around the aircraft, and output information about detected objects;
a safeguarding box building unit configured to generate, based on an aircraft geometry database, a three-dimensional safeguarding box for the aircraft; and
a risk assessment unit configured to update the safeguarding box based on data corresponding to different operation modes of the tow tug, calculate relative distances between the detected objects and the aircraft based on the information about the detected objects that is output from the sensor data processing unit, and determine whether there is a collision risk between the aircraft and an object, among the detected objects based on the updated safeguarding box,
wherein the anti-collision system is configured to output an alarm or a warning when there is the collision risk, and
wherein the risk assessment unit is configured to obtain, by using a perception algorithm, the different operation modes of the tow tug based on continuous attitude information of the tow tug and a relative azimuth between a central line of the tow tug and a central line of a belly of the aircraft, and update the safeguarding box in the different operation modes by using motion-related data.
