Problems solved by technology

[0003] The lack of existing technology, due to the large amount of welding, more than 50,000 welding heads, each group is equipped with 2 cameras, and the recording time is about 40 to 50 minutes. If manual viewing, it will consume a lot of manpower and time, but the video volume is too large Big, too time-consuming and manpower-consuming, and too low efficiency, causing the video to be viewed only when there is a problem with the welding head

specific Embodiment approach

[0059] The specific implementation method is carried out successively according to the following steps:

[0060] Label the training set. Use the target detection labeling tool to mark the absolute coordinates of the target to be detected in the picture;

[0061] Choose the deep learning network, and choose yolov4, which is relatively easy to use in the industry. Since it is an open source algorithm, it is an existing technology, so I won’t go into details here;

[0062] The camera and work area angles of the welding scene change relatively little. Initialize the three variables of historical detection part information, corresponding count and cumulative score;

[0063] The results for each frame of the video are compared with the historical parts. Judging the objects in the variables of the historical detection components, if the category is the same and IOU>0.1, it is the same object, and merged according to. If the IOU is 0 but the similarity > 0.8, the target is moved a...

Abstract

The invention provides a method and a device for detecting and tracking key components. The method comprises the following steps: acquiring first component information in a first video image and second component information in a second video image; comparing the first component information with the second component information to generate a component information adjusting instruction; and adjusting the first component information according to the information adjustment instruction.

Description

technical field [0001] The invention relates to the technical field of welding head operation quality detection, in particular to a detection and tracking method and device for key components. Background technique [0002] At present, there are 18 railway bureaus in my country, with a total of more than 180 railway sections, all of which have been equipped with recorders or cameras for welding video recording. All welding head welding records will be handed over to the railway section. It is hoped that by viewing the video, we can find out the problems in the welding process, and it will also help to clarify the responsibility for the accident. Welding consists of multiple processes, and each process has multiple item positions that need to be clamped. Among them, the visual method is mainly used to locate the key moments such as the start and end of warm-up, the start and end of reaction, the moment of sedation, the moment of mold removal, and the moment of mold push.
