Three-dimensional view display method and device based on digital twinning

The invention discloses a three-dimensional view display method and device based on digital twinning. The method comprises the following steps: acquiring a target monitoring image containing a target monitoring item on target monitoring equipment; wherein the target monitoring equipment is equipment without a data transmission interface in a monitoring site; the target monitoring item is an item which needs to be monitored on the target monitoring equipment to obtain the operation and use condition of the target monitoring equipment; inputting the obtained target monitoring image into an image processing model corresponding to a target monitoring item on the target equipment, and identifying image content corresponding to the target monitoring item on the target monitoring image by the image processing model to obtain predicted operation and use data corresponding to the target monitoring item; displaying the obtained predicted operation and use data in a three-dimensional view and a three-dimensional model c
