Description

Background Art

[0002] The girth weld of a long-distance oil and gas pipeline refers to a circular weld formed by full-position welding of two relatively fixed pipelines. In order to ensure the quality of welding, it is necessary to detect the girth weld of the pipeline to understand the defects in the girth weld so as to make corresponding repairs. At present, the main girth weld detection methods are X-ray (including film (RT) and digital imaging (DR)), automatic ultrasonic testing (AUT) and phased array ultrasonic testing. DR does not require film development and has the advantages of digital storage, computer analysis of defect images, and remote film evaluation. It is gradually replacing the use of RT; RT film can also be converted into digital images for transmission and storage. The application ratio of full-position automatic welding of pipelines is constantly increasing. Since full-position automatic welding uses small angles and narrow gap grooves, AUT uses serial scanning technology, which can measure the defect height and has a high detection rate for unfused automatic welding grooves. It is currently the most effective method for detecting full-automatic girth welds of pipelines. DR and AUT have been widely used in the construction of long-distance oil and gas pipeline projects.

[0003] However, since the two detection methods of DR and AUT are each systematic, with different display modes and different defect location positioning accuracy, it is necessary to carry out defect analysis and evaluation on different software operating platforms. In pipeline engineering, the above two methods are often used to detect the same inspection object. When analyzing and evaluating the two inspection results, professional technicians need to repeatedly switch between the two softwares to repeatedly confirm the circumferential position, length, height, depth and other information of the defect, which is time-consuming and laborious.

[0045] Exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention can be implemented in various forms and should not be limited to the embodiments set forth herein.

[0046] Figure 1A flow chart of an embodiment of a method for view alignment and display of pipeline weld defect detection provided by the present invention is shown. The method for view alignment and display of pipeline weld defect detection can be executed by an electronic device such as a terminal device or a server. The terminal device can be any fixed or mobile terminal such as a user equipment (UE), a mobile device, a user terminal, a terminal, a cellular phone, a cordless phone, a personal digital assistant (PDA), a handheld device, a computing device, a vehicle-mounted device, a wearable device, etc. The server can be a single server or a server cluster composed of multiple servers. Any electronic device can implement the method for view alignment and display of pipeline weld defect detection by calling computer-readable instructions stored in a memory by a processor. Figure 1 As shown, the following steps are included:

[0047] S1. Acquire an original DR image and fully automatic ultrasonic testing data representing defect detection results of a same pipeline weld, and sequentially perform format conversion, length calibration and identification on the original DR image to obtain a target DR image.

[0048] Among them, the pipeline weld is the girth weld of the oil and gas pipeline. In order to realize the view alignment display of pipeline weld defect detection, both detection methods are aimed at the same pipeline weld for defect detection. The defect detection area of ​​the two detection methods is the same, and the display form of the detection results is different. The original DR image is: the DR image directly obtained by using digital imaging technology to detect defects on the same pipeline weld. The fully automatic ultrasonic detection data is: the data obtained by using fully automatic ultrasonic detection technology to detect defects on the same pipeline weld.

[0049] S2. Align the target DR image with the fully automatic ultrasonic detection data, and display them on the same screen through a target display device.

[0050] The target display device may be a display screen, a computer, a tablet, or other device with a display function, and there is no limitation here.

[0051] In an optional manner, the step of performing format conversion, length calibration and identification on the original DR image in sequence to obtain a target DR image includes:

[0052] The image format of the original DR image is converted into a BMP image format to obtain a first DR image.

[0053] The image format of the original DR image is: DICONDE (.dcm) format data. The first DR image is: a DR image in BMP image format. The image format of the original DR image is converted into BMP image format using a format conversion tool (software).

[0054] The first DR image is calibrated in length using a dual-wire image quality meter to obtain a second DR image.

[0055] The second DR image is a DR image after length calibration. The specifications of the dual-wire image quality meter are standard values. The dual-wire image quality meter area is delineated, and the edge boundary is adjusted to obtain the number of pixels in the length direction of the first DR image. The distance represented by each pixel is calculated to complete the length calibration of the first DR image, thereby achieving accurate positioning and measurement of the DR image length.

[0056] The position mark and the overlap mark of the second DR image are identified to obtain the target DR image including the position mark and the overlap mark.

[0057] Among them, the target DR image is a DR image for position mark and overlap mark identification. The defect detection process uses a marker tape and an overlap mark, and its specifications are standard values. Based on the DR image length calibration, an algorithm is written to identify the position mark and overlap mark in the DR image, determine the length of the marker tape 0 point and other marks, achieve 0 point positioning, and obtain a target DR image containing the position mark and overlap mark.

[0058] In an optional manner, the step of aligning the target DR image with the fully automatic ultrasonic detection data includes:

[0059] The length position information in the target DR image is associated with the length position information in the fully automatic ultrasonic detection data to achieve automatic alignment of the target DR image with the fully automatic ultrasonic detection data.

[0060] Among them, the length direction and position of the target DR image have been digitized. The fully automatic ultrasonic detection data is collected by the encoder. The fully automatic ultrasonic detection data itself carries digitized length information. The 0 point of the target DR image and the fully automatic ultrasonic detection data are associated with the length positions of 50mm, 100mm, 150mm, 200mm, etc., to achieve automatic alignment of the 0 point of the DR image and the fully automatic ultrasonic detection data.

[0061] In an optional manner, the step of displaying the target DR image and the fully automatic ultrasonic detection data on the same screen through a target display device includes:

[0062] The display area of ​​the target display device is split into views to form a first display area and a second display area.

[0063] The target DR image is displayed through the first display area, and the fully automatic ultrasonic detection data is displayed through the second display area.

[0064] Among them, the first display area defaults to the left side of the display area, and the second display area defaults to the right side of the display area, realizing the same-screen (same-view) display of DR images and fully automatic ultrasonic detection data.

[0065] In an optional manner, the method further includes:

[0066] S3. In the target display device, a pointer is used to realize the linkage between the DR image corresponding to any defect detection area of ​​the same pipeline weld and the fully automatic ultrasonic detection data.

[0067] Among them, the automatic linkage between the DR image of any defect detection area of ​​the same pipeline weld and the fully automatic ultrasonic detection data is realized through pointers such as data lines, reference lines, and measurement lines.

[0068] It should be noted that DR image processing and annotation are implemented in data linkage mode. Image scaling adjusts the size of the image in a non-distorted way, making the details more visible and the overall observation range wider. The image is flipped horizontally / vertically to visually present a mirror effect. The image can be rotated 90 degrees clockwise or counterclockwise, or 180 degrees. The rotation operation can change the direction and angle of the image, helping the inspection technicians to better observe and understand the image content. The image negative function reverses the brightness value of the image, highlights the details and contrast in the image, and makes it easier for the inspection technicians to perceive some subtle changes and features. In addition, image defect marking can be realized in data linkage mode. When the inspection technician selects an area on the DR view, the number and location information of the defect will be automatically displayed in the defect list. The inspection technician can also fill in the required information in the description section of the defect list. Adding defect information allows inspection technicians to better track and analyze defects, so as to better carry out subsequent processing and decision-making.

[0069] The technical solution of this embodiment solves the problem of repeated switching between different software operating platforms when comparing and analyzing DR images and fully automatic ultrasonic detection data, which helps detection professionals to conduct comparative analysis and evaluation, avoids problems such as repeated switching between different software platforms, unintuitive data comparison, and lack of linkage, thereby improving the efficiency of pipeline weld defect detection.
