Bar length anomaly detection method, system and device and medium

Abstract

The invention provides a bar length anomaly detection method, system and device and a medium, and the method comprises the steps: collecting a bar image, marking a bar in the bar image, and obtaininga target data set; training the target data set through an identification network to obtain an identification model; detecting a real-time bar image through the identification model to obtain associated information characteristics of the bar, wherein the associated information characteristics include a number and a length; and determining the number and the length corresponding to the abnormal baraccording to the associated information characteristics. The real-time bar images are detected through the recognition model to obtain the associated information characteristics of the bars, judgement is conducted according to the obtained associated information characteristics of the bars, the numbers and the lengths corresponding to the bars with the abnormal bar lengths are obtained, the detection efficiency and timeliness are improved, and personal errors and construction safety hazards caused by manual judgment are avoided.

Description

technical field [0001] The invention relates to the technical field of detection, in particular to a detection method, system, equipment and medium for abnormal length of rods. Background technique [0002] At the short-length separation detection point in the hot rolling production process, it is necessary to sort the bars that do not meet the specified length to ensure the quality of the bars. At present, this type of situation is mainly judged and identified manually. In the face of a long-running production line, if only relying on manual inspection of bars, there will inevitably be false inspections and missed inspections, and it does not have real-time performance. At the same time, the on-site working environment is extremely harsh, and there are huge potential safety hazards. Contents of the invention [0003] In view of the above-mentioned shortcomings of the prior art, the purpose of the present invention is to provide a detection method, system, equipment and ...
