Abstract

The invention belongs to the technical field of image data processing or generation, and discloses a method and system for quantitatively analyzing hidden dangers of earth-rock dams based on digital image processing. The three-dimensional resistivity image is generated by using the resistivity data and corresponding coordinates after resistivity test inversion; The resistivity image is processed to obtain the internal resistivity image of the earth-rock dam; the geometric characteristic parameters of the hidden dangers of the earth-rock dam are extracted according to the internal resistivity image of the earth-rock dam; the earth-rock dam is diagnosed by quantitative analysis of the characteristic parameters of the hidden dangers of the earth-rock dam. The digital image processing process of the present invention is fast, highly automated, and highly operable; the image results are intuitive, and abnormal information is easy to find, so the reliability is high; the distribution of hidden dangers in the dam body can be directly observed, and the hidden dangers of earth-rock dams can be quantitatively analyzed to achieve accurate for diagnostic purposes.

Description

technical field [0001] The invention belongs to the technical field of image data processing or generation, and in particular relates to a method and system for quantitatively analyzing hidden dangers of earth-rock dams based on digital image processing. Background technique [0002] At present, the existing technologies commonly used in the industry are as follows: Nearly 90% of the completed dykes and dams in my country were built in the 1950s to 1970s. Most of them are "three-sided" projects with low engineering design standards and poor construction quality. Various hidden dangers have emerged after many years of operation. At present, the traditional methods for hidden danger detection of earth-rock dams in my country include flow field method, tracer method, two-dimensional high-density resistivity method, etc. The flow field method is an electrical detection technology for detecting the location of the seepage entrance of the embankment. The detection equipment is ma...

Problems solved by technology

[0003] In summary, the problems in the prior art are: The traditional method of hidden danger detection in earth-rock dams has a small amount of measurement information. It can only detect the approximate location of hidden dangers and judge the overall direction of hidden dangers. It cannot accurately describe the spatial distribution of hidden dangers in the dam body. The accuracy of the measurement results is easily disturbed by the external environment. In the case of multiple measurements and multiple results, the degree of harm of hidden dangers cannot be quantitatively analyzed. The measurement process may cause secondary damage to the dam body and cause damage or pollution to the environment. The technology itself is complicated to operate, with high efficiency and low cost, and the interpretation of results needs further processing
