Pipeline leakage analysis method, device and computer readable storage medium

The invention discloses a pipeline leakage analysis method, a device and a computer readable storage medium. The method comprises the following steps: processing an original image containing a riverway region by utilizing an edge detection algorithm so as to establish a riverway model used for representing position information, riverway contour and shape information of a target riverway region which is not more than a first preset distance threshold from a leakage port in the upstream direction and is not less than a second preset distance threshold in the downstream direction; establishing apipeline leakage point model through multilayer grid nesting according to the information of the conveying pipeline passing through the target riverway area; the method is based on a riverway model and a pipeline leakage point model. The Mixture mixed model is used for carrying out fluid leakage analysis through fluid mechanics to obtain the leakage diffusion characteristic data of the conveying pipeline, so that the prob
