Problems solved by technology

[0003] Taking pedestrian simulation technology as an example, the existing pedestrian simulation algorithm mainly relies on random walk, so it lacks global road planning and is difficult to approach the real scene. In addition, it does not consider factors such as traffic rules and traffic signals, so it is difficult to Applied to scenarios related to vehicle traffic, even if it can realize the anti-collision function of people and vehicles, it can only adapt to extremely low-speed scenarios, and cannot realize more intelligent simulation requirements

Abstract

The embodiment of the invention discloses a moving trajectory simulation method, device, equipment and storage medium. The method includes: dividing the activity area into a plurality of unit blocks in at least two dimensions, wherein a high-dimensional unit block includes a plurality of adjacent low-dimensional unit blocks; The unit generates the path planning result of the moving object from high dimension to low dimension; according to the path planning result, the movement trajectory corresponding to the moving object is generated. Through the technical solution of the present invention, the simulation of the moving track can be closer to the complex and changeable real scene, so that the simulated movement of the moving object is more intelligent.

Description

technical field [0001] Embodiments of the present invention relate to path planning technology, and in particular, to a method, device, equipment, and medium for simulating a moving trajectory. Background technique [0002] Trajectory simulation technology, especially pedestrian simulation technology, is mainly used to simulate the trajectory of moving objects. It is widely used in various scene simulations such as game development, traffic rules, and vehicle automatic driving tests.
