Abstract

The invention provides an oil leakage defect detection method and system. The system comprises an ultraviolet light source module, a visible light imaging module, a parameter setting module, a displaymodule, an alarm module and an image analysis module. The method comprises the following steps: S1, fixing relative positions of an ultraviolet light source module and a visible light imaging module,wherein the irradiation direction of the ultraviolet light source module is relatively parallel to the shooting direction of the visible light imaging module, and after the ultraviolet light source module irradiates an area to be detected, the visible light imaging module collects high-definition image data of the area to be detected and transmits the high-definition image data to the image analysis module; S2, enabling an image analysis module to receive the high-definition image data, and obtain an oil leakage defect detection and recognition result through image analysis and processing; S3, transmitting the image and text information of the oil leakage defect detection and recognition result to a display module for display, and transmitting a detection and recognition result signal toan alarm module for alarming. According to the invention, the anti-interference capability of the environment is enhanced, and the influence of personal experience on detection results is avoided.

Description

technical field [0001] The present invention relates to the technical field of oil leakage detection and identification, and more specifically, to an oil leakage defect detection method and system. Background technique [0002] At present, most of the methods for detecting oil leakage use manual patrolling, and require a certain amount of experience to distinguish through artificial "visual inspection" and "nose sniffing". The effect of manual inspection is greatly affected by work experience, and it takes a lot of time and is inefficient. In recent years, fluorescence detection technology has been widely used in the fields of oil exploration and development, monitoring of oil pollutant content in soil, aircraft hydraulic oil leakage and sea surface oil spill monitoring, and a large number of research results have been obtained, which have verified the effectiveness of oil fluorescence detection method. sex. However, there are problems of lack of anti-interference ability ...
