[0037] Please refer to image 3 , image 3 A method for reconstructing a dam model provided by an embodiment of the present invention is shown. The above-described dam model reconstruction method is applied to the electronic device 100 . like image 3 As shown, the above-mentioned method for reconstructing a dam model may include the following steps:

[0038] Step S101 , acquiring a plurality of initial image data carrying the collection location information and including the dam.

[0039] In the embodiment of the present invention, the initial image data of the dam from multiple angles collected by the drone is received. It should be noted that each time the UAV collects a piece of image data including a dam, the GPS information of the UAV at this time is written into the image attributes of the collected image data as the collection location information, so as to obtain the initial image data. image data.

[0040] Step S102 , using a pre-trained semantic segmentation l...

Abstract

The embodiments of the present invention provide a method, device and electronic device for reconstructing a dam model, which relate to the technical field of water conservancy. The method for reconstructing a dam model includes: acquiring a plurality of initial image data carrying the collection location information and including the dam; using a pre-trained semantic segmentation learning model for identifying the defect area of ​​the dam to process each piece of the initial image data to obtain an identifiable obtain the semantic segmentation binary map of the defect area of ​​the dam; respectively fuse each of the initial image data and the corresponding semantic segmentation binary map to obtain the image to be reconstructed; based on the multiple images to be reconstructed and the corresponding Three-dimensional reconstruction is performed on the collected position information to obtain a dam model marking the defect area of ​​the dam. Accurate positioning of defects is achieved, which is conducive to timely discovery of potential safety hazards in dams and saves labor costs.

Description

technical field [0001] The present invention relates to the technical field of water conservancy, in particular, to a method, device and electronic device for reconstructing a dam model. Background technique [0002] Dams belong to the infrastructure of water conservancy projects, which have a great impact on the quality of people's livelihood and economic development. With the rapid increase of water conservancy projects, intelligent inspection of the infrastructure of water conservancy projects has become a mainstream trend. [0003] At present, intelligent inspection mainly collects dam images, then reconstructs the 3D model based on the collected dam images, and finally manually checks the 3D model of the dam to find the location of the dam defect. Among them, the labor cost is extremely high and it is easy to miss some defects, making it difficult to find the hidden safety hazards of the dam in time. SUMMARY OF THE INVENTION [0004] In view of this, the purpose of ...
