Abstract

The invention provides a track rationality evaluation and self-generation method and system based on a given node sequence, and relates to the technical field of computer graphics real-time rendering. The method comprises the steps of 1 defining necessary parameters of an algorithm; 2 judging the legality of a node sequence according to the defined necessary parameters; and step 3 automatically generating a track based on a legal track node sequence. According to the node sequence rationality determination method based on the environmental parameter constraint, track self-generation conforming to the kinematics constraint can be carried out on the node sequence.

Description

technical field [0001] The present invention relates to the technical field of real-time rendering of computer graphics, in particular to a method and system for evaluating and self-generating track rationality based on a given node sequence. Background technique [0002] The track refers to the track of a ship or an aircraft when it is sailing. The aircraft will be affected and interfered by various factors during the navigation and cause navigation errors, so the track is generally not a straight line. Aircraft trajectory planning is to plan the optimal or satisfactory flight path for the aircraft under the premise of comprehensively considering the arrival time, fuel consumption, threat and flight area of ​​the aircraft, so as to ensure the successful completion of the flight mission. During actual air combat confrontation or flight control simulation experiments, the aircraft (real or simulated) is required to fly along a small number of designated track nodes within the...
