Integrated lane changing behavior simulation method oriented towards vehicle animation simulation

Abstract

The invention discloses an integrated lane changing behavior simulation method oriented towards vehicle animation simulation. The method includes the coordinate system building step, wherein a lane changing track of a vehicle to change a lane is built on the basis of a moving coordinate system, the current position of the vehicle to change the lane serves as the origin of the moving coordinate system, the transverse axis of the moving coordinate system is in the lane line direction of the vehicle to change the lane, and the longitudinal axis of the moving coordinate system is in the direction perpendicular to the transverse axis; the lane changing track describing step, wherein the offsets of the lane changing track in the transverse axis and the longitudinal axis are described respectively on the basis of the moving coordinate system; the track restraint step, wherein a restraint condition is formed on the basis of influence on the lane changing track from multiple influence factors; the track obtaining step, wherein the lane changing track is restrained on the basis of the constraint condition, and the final lane changing track of the vehicle is obtained.

Description

technical field [0001] The invention relates to the fields of traffic simulation and computer graphics, in particular to an integrated lane-changing behavior simulation method for vehicle animation simulation. Background technique [0002] With the development of 3D virtual modeling technology, many 3D virtual simulation systems need to incorporate realistic vehicle animation simulation effects, such as virtual earth, city engine, city life and other application software and games. There are a large number of on-ramps, merges, intersections, and accident sections in the urban road network, where a large number of vehicles will change lanes. Therefore, realistic and detailed lane-changing behavior simulation not only helps to improve the authenticity of traffic simulation, but also improves the credibility of simulation results. [0003] Existing lane-changing simulation methods are mainly decision-based methods. These methods simplify the behavior of changing lanes to an i...
