[0033] In order to make the purpose, features and advantages of the present invention more obvious and easy to understand, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0034] See also Figure 1 The embodiment of the present invention provides a method for searching and locating a water meter during storage, which includes the following specific steps:

[0035] Step 100: an information barcode is provided on a packaging box of the water meter, the information barcode at least carrying water meter information of the water meter in the packaging box;

[0036] Step 200: collecting images of the water meter stack to obtain a stack picture;

[0037] Step 300: performing regional positioning on the information barcode in the stacking image;

[0038] Step 400: Identify the water meter information carried by the information barcode in the stacking image;

[0039] Step 500: Write the identified water meter information into the list in sequence to generate a stacked data list;

[0040] Step 600: The data lists of each stack are stored and aggregated to form a total data list.

[0041] The present embodiment provides a method for searching and locating water meters during storage, which sets an information barcode on a packaging box of the water meters, and each packaging box contains a number of water meters, the information barcode carries at least water meter information of each water meter in the packaging box, and then collects an image of a stack of water meters to obtain a stacking picture; performs regional positioning on the information barcode in the stacking picture; identifies the water meter information carried by the information barcode in the stacking picture; writes the identified water meter information into a list in turn to generate a data list for the stack; stores and aggregates the data lists of each stack to form a total data list, and when it is necessary to search for a water meter, the search can be performed based on the data list, so that it can achieve accurate and efficient search for the water meter.

[0042] Specifically, the information barcode in this embodiment can be a QR code and a barcode; the number of barcodes can correspond to the number of water meters in the packaging box, and each barcode carries the meter number information of the water meter.

[0043] For example, in this embodiment, the stack of water meters can be photographed by a camera, or even a mobile phone camera. The side of the water meter stack can be photographed. During the stacking process of the water meters, the packaging boxes can be placed in a staggered manner, and the barcode with information can be placed facing outward. Specifically, when the factory packs the water meters, it will enter the meter number corresponding to the water meter in a box to generate a QR code / barcode and paste it on the side of the carton. And in the process of stacking the cartons, ensure that the sides with labels on all cartons face outward, which provides conditions for image recognition, as long as the four sides of the stack are photographed.

[0044] In a further feasible implementation of this embodiment, after collecting the image of the water meter stack to obtain the stack picture, the search and positioning method further includes preprocessing the stack picture.

[0045] In this embodiment, by pre-processing the stacked images, it is possible to improve the image quality and prevent errors from occurring during subsequent image processing.

[0046] In a further feasible implementation of the present embodiment, collecting images of the water meter stack to obtain a stacking picture specifically includes: collecting images of the four sides of the water meter stack to obtain stacking pictures of the four sides of the water meter stack, and correspondingly, preprocessing the stacking picture specifically includes: splicing and sorting the stacking pictures of the four sides, and labeling the stacking pictures of each side with a picture number.

[0047] In this embodiment, by collecting pictures of the four sides of the water meter stack, stitching and sorting the stack pictures on the four sides, and marking the stack pictures on each side with picture numbers, the accuracy and efficiency of the subsequent water meter search process can be improved.

[0048] Specifically, the stack of water meters can be marked as the first side, the second side, the third side and the fourth side respectively, and then the pictures taken from the four sides are stitched and sorted, and then each side is marked during the picture processing process, so that the corresponding side can be searched in the subsequent search, and there is no need to search for the water meter in the entire stack. In this embodiment, the first side, the second side, the third side and the fourth side can correspond to the front, the back, the left side and the right side, and the pictures of the front, the back, the left side and the right side are stitched into the upper left corner, the upper right corner, the lower left corner and the lower right corner of a picture in sequence. The stitching positions are as follows: Figure 4 As shown, the image brightness and contrast are finally adjusted, noise interference is removed, and the reflective area of ​​the image is processed.

[0049] For example, mark the side of the water meter stack as No. 1, and then mark the surface corresponding to the mark when processing the stack image. In this way, when you need to find it later, you can directly go to the side of the water meter stack marked as No. 1 to find the water meter, and you can quickly find the corresponding packaging box on the side No. 1.

[0050] In a further implementable method of this embodiment, performing regional positioning on the information barcodes in the stacking image specifically includes: sorting the information barcodes in the stacking image on each side, and marking the position of each barcode.

[0051] In this embodiment, the information barcodes in the stacking image on each side are sorted and the position of each barcode is marked, which can improve the accuracy and efficiency of the subsequent water meter search process.

[0052] Specifically, after the stacking pictures are collected, the QR code / barcode areas are sorted in order from left to right and from top to bottom.

[0053] For example, when identifying information barcodes, they can be sorted. For example, if the position of the information barcode is the first position from the left in the top row or the second position from the left in the second row from top to bottom, then in subsequent searches, you can directly go to the corresponding side surface of the stack and the corresponding specific position for search, which makes the search simpler, more convenient, accurate and efficient.

[0054] In a further feasible implementation of this embodiment, before stitching and sorting the stacked images on the four sides, preprocessing the stacked images specifically includes adjusting image brightness and contrast, removing noise interference, and processing image reflective areas.

[0055] The preprocessing of the stacked images in this embodiment specifically includes adjusting the image brightness and contrast, removing noise interference, and processing the image reflective area, which can greatly improve the quality of the image and further improve the accuracy of image recognition.

[0056] In a further feasible implementation of the present embodiment, the search and positioning method also includes obtaining the identification or location information of each water meter stack, where the water meter information is the table number of the water meter, and writing the identified water meter information into a list in sequence to generate a data list of the stack, which specifically includes: writing the identification or location information of the water meter stack, identifying the image number of the stack, identifying the location information of the barcode, and the table number information of the water meter into a list to generate a data list of the stack.

[0057] The data list in this embodiment at least involves the identification or location information of the water meter stack, the stacking picture number identification, the barcode location information identification and the corresponding water meter information. Therefore, when searching, you only need to enter the water meter information (such as the water meter number information). Based on the water meter information, there are also the identification or location information of the water meter stack, the stacking picture number identification, and the barcode location information identification corresponding to it. That is, you can first find the stacking position of the water meter, then search on the side corresponding to the image number identification, and then directly search at the position corresponding to the barcode on this side, which can quickly realize the search of the water meter.

[0058] In a further feasible embodiment of the present invention, the search and positioning method further includes searching for the water meter location and updating the data list, wherein searching for the water meter location specifically includes: inputting water meter information, searching in the data list, and obtaining query results, and updating the data list specifically includes: when the water meter has gone out, updating the water meter status in the data list to "out of storage".

[0059] In this embodiment, the outbound information can also be updated, which can make it easier to track the status of the water meter and determine whether the water meter to be found is still in inventory.

[0060] See also Figure 3 Schematic diagram of the process of water meter entering the warehouse and see Figure 4 The schematic diagram of the water meter in the search process, the working process is as follows:

[0061] 1. Image acquisition: Take four pictures of the water meter stack from the front, back, left and right sides, and then upload the pictures to the image recognition system;

[0062] 2. Image preprocessing: First, identify the stacking area in the picture and remove the redundant area. Then, stitch the collected pictures. Splice the front, back, left and right pictures to the upper left corner, upper right corner, lower left corner and lower right corner of a picture in turn. The stitching position is shown in Figure 3. Finally, adjust the picture brightness and contrast, remove noise interference, and process the reflective area of ​​the picture.

[0063] 3. QR code and barcode area positioning: First, the QR code / barcode area contained in the stack in the picture is selected by image recognition, and then the QR code / barcode areas are sorted from left to right and from top to bottom to wait for recognition;

[0064] 4. Identification information: Identify and read the table number information in the QR code / barcode in sequence, exclude the QR code / barcode whose identification result is not the table number information, and then write the table number read from each QR code / barcode into the list in sequence to generate a stacked table number data list Lin-xxx (xxx represents the stacking sequence number);

[0065] 5. Summarize data: Summarize the data list Lin-xxx of each stack into the total data list Lall for later search;

[0066] 6. Positioning search: Enter the table number to be searched, search in the data list Lall, get the query result, indicate the stack data list Lin-xxx where the target water meter is located, and highlight the target table number in the stack list. Find the target water meter in the corresponding water meter stack according to the stack sequence number and table sequence number;

[0067] 7. Update the list: When the water meters are shipped out of the warehouse, the stack of water meters shipped out of the warehouse is photographed and identified, and the outbound list Lout-xxx is generated. At the same time, the status of the shipped water meters in the total data list Lall is changed from 'in warehouse' to 'shipped'.

[0068] Another aspect of the present invention provides a system for finding and locating a water meter during storage, comprising:

[0069] The image acquisition unit 10 is used to acquire the image of the water meter stack to obtain a stack image;

[0070] The area positioning unit 20 is used to perform area positioning on the information barcode in the stacking picture;

[0071] An information recognition unit 30, used to recognize water meter information carried by the information barcode in the stacking picture;

[0072] A list generating unit 40 is used to write the identified water meter information into a list in sequence to generate a stacked data list;

[0073] The data storage unit 50 is used to store and aggregate the data lists of each stack to form a total data list.

[0074] In a further implementable manner of this embodiment, the positioning system further includes: an image preprocessing unit, which is used to preprocess the stack image after collecting the image of the water meter stack to obtain the stack image.

[0075] In a further feasible implementation of the present embodiment, collecting images of the water meter stack to obtain a stacking picture specifically includes: collecting images of the four sides of the water meter stack to obtain stacking pictures of the four sides of the water meter stack, and accordingly, the picture preprocessing unit is specifically used to splice and sort the stacking pictures of the four sides, and to identify the picture number of the stacking picture of each side.

[0076] In addition, in the prior art, if it is necessary to trace and search the water meter, it is necessary to manually enter the production data list for each stack of multiple packaging boxes and the water meter number in each packaging box when the water meter is put into storage. The entire workload is cumbersome and huge, which greatly hinders the warehousing of products. The search and positioning system for water meters in the storage process of the present invention has a simple and convenient data list generation process, and the data list can be generated after the water meter is put into storage, which can greatly improve the convenience of warehousing.
