Sand table deduction method and device based on digital twinning, equipment and storage medium

Abstract

The invention relates to a sand table deduction method and device based on digital twinning, equipment and a storage medium. The method comprises the steps of generating a scene video animation according to a model motion type and motion data in a to-be-simulated real scene; extracting image features of the moving target by applying a set moving target detection algorithm, and determining a targetmodel matching the moving target; identifying the type of the target model, and determining the type of the moving target; querying a target motion type of the type of the moving target in an actionlibrary, and binding a target algorithm corresponding to the target motion type; counting the moving targets bound with the corresponding algorithms and the moving targets not bound with the corresponding algorithms in the scene to update the scene; planning a movement track of the moving target according to the collision volume of the moving target and a target algorithm; and determining the motion trails of all moving targets in a set time period to realize sand table deduction. The real possible conditions can be reflected more easily, the mutual influence among multiple targets is considered, simulation is carried out respectively, the trajectory prediction steps are simplified, and the calculated amount is reduced.

Description

technical field [0001] The present invention relates to the field of digital twins, in particular to a sand table deduction method, device, equipment and storage medium based on digital twins. Background technique [0002] Digital twin technology is to make full use of data such as physical models, sensor updates, and operation history, integrate multi-disciplinary, multi-physical quantities, multi-scale, and multi-probability simulation processes, and complete the mapping in the virtual space, thereby reflecting the full range of the corresponding physical equipment. life cycle process. [0003] The current sand table deduction is biased towards virtual simulation deduction. Place a sand table, place entities in the sand table and set certain rules to constrain the entities, so that the objects in it can change according to certain rules or limit movement. At this time, sand table deduction is more inclined to change However, for simulating the reality as a sand table, whe...
