Description

Technical Field

[0001] The present invention relates to the field of image processing technology, and in particular to a method, device, electronic equipment and storage medium for detecting a pigtail occupied port. Background Art

[0002] The goal of the splitter pigtail occupied port detection method is to detect the port occupancy status of the splitter pigtail in real time by identifying on-site photos taken by installation and maintenance personnel, so as to determine whether the installation and maintenance construction meets the requirements.

[0003] Existing technical solutions use semantic segmentation algorithms to detect splitter pigtail labels. After identifying the label and port location, the algorithm calculates and selects the port with the highest overlap between the target pixel position and the pixels in any port detection area. However, this results in high target recognition error rates and low detection accuracy. If multiple labels are present in a device image, the label position on the pigtail cannot be accurately identified, leading to other labels being mistakenly identified as the target pigtail label. Furthermore, the occupied port number is derived by calculating and selecting the overlap between the target pixel position and the pixels in any port detection area, affecting detection accuracy.

[0040] To make the objectives, technical solutions, and advantages of the present invention more clear, the technical solutions of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0041] The following combination Figures 1-9 The present invention describes a method, device, electronic device and storage medium for detecting a pigtail occupied port.

[0042] Figure 1 A schematic diagram showing a process flow of a method for detecting a pigtail occupied port according to the present invention is shown. Figure 1 , the method comprising:

[0043] 11. Determine a pigtail port identification area and a pigtail label identification area in the image to be inspected; wherein the plurality of pigtail ports in the image to be inspected are arranged, the labels in the image to be inspected do not overlap, the labels include a content portion and a connecting portion, and the width of the content portion is different from the width of the connecting portion;

[0044] 12. Determine the border area of ​​each pigtail port in the pigtail port identification area, and determine the border area of ​​the label in the pigtail label identification area;

[0045] 13. Determine the occupied port of the pigtail to which the label belongs based on the border area of ​​each pigtail port and the border area of ​​the label.

[0046] In this regard, it should be noted that in the present invention, the pigtail is also called a pigtail, which has a connector at only one end, and the other end is the broken end of an optical cable core, which is connected to other optical cable cores by fusion splicing and often appears in optical fiber equipment (such as splitters).

[0047] Fiber optic equipment is equipped with multiple ports that facilitate the insertion of pigtails. Since these ports are used for pigtail insertion, they are referred to as pigtail ports in the description of the present invention. These ports are arranged in sequence. For example, they are placed in sequence from left to right. Fiber optic equipment is an existing product, so the port arrangement on the fiber optic terminal is not shown in the accompanying drawings. In actual applications, these ports are sometimes all plugged into the connectors of the pigtails, and sometimes partially plugged into the connectors of the pigtails. Therefore, when identifying the ports, the identification area includes both ports with connectors plugged in and ports without connectors plugged in.

[0048] The pigtail is equipped with a corresponding label. This label consists of a content section and a connection section. The content section is printed with text describing the pigtail. The connection section is used to loop around the pigtail cable.

[0049] In the present invention, the width of the content portion is different from the width of the connecting portion. The connecting portion mainly plays the role of binding cables, so the width of the connecting portion is narrower than the width of the content portion.

[0050] In this invention, the method uses on-site images captured by installation and maintenance personnel to detect port occupancy at fiber optic terminals in real time, thereby determining whether installation and maintenance work meets requirements. This determination of compliance relies on verifying whether the labeled fiber pigtails are plugged into the correct ports. To achieve this, the labels in the image to be inspected must not overlap. Typically, only one complete label is displayed in the image. This effectively allows for individual determination of the connection status of each fiber pigtail.

[0051] In this method, after acquiring the image to be inspected, it is necessary to analyze the image to identify the pigtail port identification area and the pigtail label identification area. After the area is identified, it is marked with a square wireframe. That is, the image portion showing the port and label is circled with a square wireframe.

[0052] In the present invention, the identification area is larger than the actual size of the port and label. To this end, further analysis and processing are required for each identification area to determine the border area of ​​each pigtail port within the pigtail port identification area, and the border area of ​​each label within the pigtail label identification area. This border area more closely approximates the actual size of the port and label. In other words, the area enclosed by the edge of the port is equivalent to this border area.

[0053] In the present invention, since the identified label represents a unique pigtail, it is necessary to compare the frame area of ​​the label with the frame area of ​​each pigtail port to determine which port on the optical fiber terminal the pigtail to which the label belongs is plugged in.

[0054] The size of the label is much larger than that of the pigtail cable. Therefore, the portion of the label's border area representing the connection portion can be aligned with the border area of ​​each pigtail port, and the port corresponding to the aligned border area is used as the occupied port.

[0055] In addition, it should be noted that since the pigtail cable is a flexible product, the label may deviate during the actual process. In this case, the label in the captured image will correspond to the wrong port, resulting in a violation of the label installation requirements. Therefore, the requirements for capturing the image to be tested are relatively high. In this case, simply straighten the pigtail cable and then take the image, and the resulting image will be relatively consistent with the requirements for the image to be tested.

[0056] The method for detecting pigtail occupied ports provided by the present invention processes the image to be detected, quickly identifies the area of ​​the pigtail port and the pigtail label, then divides the frame position of each port and label from the area, and then aligns and compares the frame position to determine the specific position of the pigtail occupied port, and returns the detection result in real time, which has different degrees of improvement in calculation speed and accuracy.

[0057] In the further description of the above method, the process of determining the occupied port of the pigtail to which the label belongs based on the border area of ​​each pigtail port and the border area of ​​the label is mainly explained as follows:

[0058] If the width of the content portion is greater than the width of the connection portion, the fiber optic port corresponding to the fiber optic port frame area aligned with the narrow sides of the left and right sides of the label's border area is used as the occupied port of the fiber optic port to which the label belongs;

[0059] If the width of the content portion is smaller than the width of the connection portion, the fiber optic port corresponding to the fiber optic port whose border area is aligned with the wide sides of the left and right sides of the label's border area shall be used as the occupied port of the fiber optic port belonging to the label based on the arrangement direction of the fiber optic port.

[0060] In this regard, it should be noted that in the present invention, see Figure 2 and Figure 3 Due to the different shooting angles of maintenance personnel, a row of ports may not be strictly horizontal. If the width of the content of the label is greater than the width of the connection part, the border area of ​​the label will be Figure 2 and Figure 3 The "convex" area at the bottom.

[0061] The label is attached to the cable with the label's content located on the left or right side of the cable. Figure 2 and Figure 3 The narrow side of the label will be located on the left or right side of the border area of ​​the label. In the present invention, the portion of the label's border area that represents the connection portion can be aligned with the border area of ​​each pigtail port, and the port corresponding to the aligned border area is used as the occupied port. To this end, the narrow side represents the outer edge of the connection portion, so based on the arrangement direction of the pigtail port, the system identifies the narrow side of the left and right sides of the label's border area as representing the outer edge of the connection portion, and then the pigtail port corresponding to the border area of ​​the pigtail port aligned with the narrow side is occupied (see Figure 2 and Figure 3 The vertical dotted line in the figure, the port corresponding to the dotted line, is used as the occupied port of the pigtail to which the tag belongs.

[0062] When the width of the content is smaller than the width of the connection, the display method is the same as Figure 2 and Figure 3 Similarly, the attached figure is not used again. In this case, the arrangement direction of the pigtail port is used as a reference, and the pigtail port corresponding to the pigtail port frame area that aligns the wide sides of the left and right sides of the label frame area is used as the occupied port of the pigtail to which the label belongs.

[0063] In addition, it should be noted that since the narrow or wide edge mentioned above may be tilted during the identification process, strictly aligning and searching for the pigtail port according to the dotted line will result in detection errors. Therefore, the starting point, midpoint, or end point of the narrow or wide edge can be used to align and search for the pigtail port.

[0064] A further method of the present invention can align the outer edge of the connection part of the label in the border area of ​​the label with the border area of ​​each fiber optic port according to different label design conditions, and use the port corresponding to the aligned border area as the occupied port to achieve accurate detection.

[0065] In the further description of the above method, the process of determining the border area of ​​each pigtail port in the pigtail port identification area and determining the border area of ​​the label in the pigtail label identification area is mainly explained as follows:

[0066] The images in the pigtail port identification area and the pigtail label identification area are binarized to obtain a binary white area; the binary white area is smoothed to obtain a smooth white area, and the smooth white area is used as the corresponding border area.

[0067] In this regard, it should be noted that in the present invention, see Figure 4 and Figure 5, which respectively display the port and label. Figure 4 The white area and Figure 5 The white areas in the image represent the borders of the ports and labels, respectively, after binarization and / or smoothing of the identified regions. Images outside the identified regions are simply filled with black pixels. In this case, the white areas serve as the borders of the ports and labels.

[0068] A further method of the present invention uses binarization to process the recognition area and reduce the recognition area, which can accurately and quickly divide the ports and labels on the image to obtain the frame areas of the ports and labels.

[0069] In the further description of the above method, the process of continuing to process the smooth white area after obtaining the smooth white area is mainly explained as follows:

[0070] Perform vertical projection processing on the smooth white area to obtain the projected white pixel number histogram, and use the white pixel number histogram as the corresponding border area.

[0071] In this regard, it should be noted that, in the present invention, the divided border area has irregularities, so the border area is projected onto a horizontal baseline in a statistical manner of pixel count to obtain a histogram of the number of white pixels corresponding to each. Figure 6 and Figure 7 The white pixel count histogram is then used as the border area of ​​the port and label.

[0072] A further method of the present invention processes the smoothed white area using a vertical projection method to obtain a histogram of the number of white pixels on a unified baseline, thereby providing a more accurate reference for subsequent alignment between border areas.

[0073] In the further description of the above method, the process of determining the pigtail port identification area and the pigtail label identification area in the image to be detected is mainly explained as follows:

[0074] Obtain image features of the image to be detected, input the image features into the image recognition model, obtain the recognition results output by the image recognition model, and use the recognition results to divide the recognition areas of the pigtail port and the pigtail label;

[0075] Among them, the image recognition model is a model obtained through machine learning training that uses image features determined based on sample images and identification areas in the sample images as input, and is used to divide the fiber pigtail ports and fiber pigtail labels in the image.

[0076] In this regard, it should be noted that, in the present invention, historically stored on-site pictures of ports plugging pigtails are collected, and the pigtail port portion and label portion are annotated using graphic tools as sample pictures.

[0077] For the annotated images, a neural network model is used for training, and the parameters are adjusted according to each detection result to obtain an image recognition model that divides the pigtail ports and pigtail labels in the image.

[0078] Then, the trained model is used to identify the image to be detected and the identification areas of the pigtail port and pigtail label are divided. In the present invention, since the port position and label image features are obvious, the trained image recognition model can detect the identification areas of the port and label with good performance and accuracy.

[0079] In the further description of the above method, the processing before determining the border area is mainly explained, as follows:

[0080] Adjust the angle of the long side of the square wireframe of the identification area of ​​the pigtail port to the vertical direction or the horizontal direction, and adjust the image to be detected.

[0081] In this regard, it should be noted that due to inconsistent shooting angles by installation and maintenance personnel, when the port position is not in a horizontal position, the accuracy of the port position determination will be affected. Therefore, the port image needs to be horizontally corrected. The angle of the long side of the square wireframe in the identification area of ​​the pigtail port is adjusted to the vertical or horizontal direction, and the image to be inspected is adjusted.

[0082] In the present invention, when the port is at the top and the label is at the bottom, the device is viewed from the front. If the port is not above the label, the image is rotated by 90°, 180°, or 270°.

[0083] After the frame area of ​​each pigtail port is determined, each frame area is numbered according to a preset numbering rule to determine the port number of each pigtail port.

[0084] The following describes a device for detecting a pigtail port occupied by a fiber optic cable provided by the present invention. The device for detecting a pigtail port occupied by a fiber optic cable described below and the method for detecting a pigtail port occupied by a fiber optic cable described above can be referred to in correspondence with each other.

[0091] If the width of the content portion is smaller than the width of the connecting portion, the fiber optic port corresponding to the frame area of ​​the fiber optic port whose wide sides are aligned with the left and right sides of the frame area of ​​the label shall be used as the occupied port of the fiber optic port to which the label belongs, based on the arrangement direction of the fiber optic port.

[0097] Obtaining image features of the image to be detected, inputting the image features into an image recognition model, obtaining a recognition result output by the image recognition model, and using the recognition result to divide the recognition area of ​​the pigtail port and the pigtail label;

[0098] The image recognition model is a model obtained through machine learning training using image features determined based on sample images and identification areas in the sample images as inputs, and is used to divide the pigtail ports and pigtail labels in the images.

[0100] Adjust the angle of the long side of the square wireframe of the identification area of ​​the pigtail port to the vertical direction or the horizontal direction, and adjust the image to be detected.

[0102] Each border area is numbered according to the preset numbering rules to determine the port number of each pigtail port.
