Abstract

The invention discloses a digital twinning construction method and device, a terminal and a storage medium, and the method comprises: obtaining the observation data of an observed object collected by at least one sensor, wherein the at least one sensor comprises one sensor or a plurality of sensors of the same type or a plurality of sensors of different types; based on the Bayesian principle, calculating the posterior probability of the current moment according to the observation data, and obtaining the state of the observed object at the current moment through the posterior probability; predicting an event of the observed object at the current moment according to the state and the observation data and a preset rule; and constructing the digital twinning of the observed object according to the state and the event. By means of the method, the digital twinning which is real-time, high in robustness and accurate can be constructed, and the precision of the digital twinning is improved.

Description

technical field [0001] The present invention relates to the technical field of three-dimensional construction, in particular to a digital twin construction method, device, terminal and storage medium. Background technique [0002] Digital twin is a simulation process that makes full use of physical models, sensor updates, operation history, etc., integrates multi-disciplinary, multi-physical quantities, multi-scale, and multi-probability simulation processes, and completes the mapping in the virtual space to reflect the entire life cycle of the corresponding physical equipment. Process, which is used in many fields, is currently widely used in product design, product manufacturing, medical analysis, engineering construction and other fields. [0003] Existing digital twin construction technologies rely unilaterally on the data quality of sensors. In reality, sensor data is inaccurate, unreliable, and unable to provide direct information. Therefore, existing technologies cann...
