Problems solved by technology

[0004] However, the placement of packages on the sorting line is usually not standardized, for example, there may be more than two packages stacked on top of each other, which can easily lead to errors in the weight weighed on the sorting line
If a group of packages currently being weighed is stacked by two packages, and only one package on top is automatically recognized, but the weight obtained by weighing is the total weight of the two packages, the total weight will only be used as As the weight of a package above, this will lead to a significant difference between the weight weighed on the sorting line and the weight uploaded by the courier
Once the courier company pays the freight to the customer based on the weight weighed on the sorting line, it will bring undue expenses to the customer or lead to adverse consequences such as disputes

Embodiment 1

[0048] Taking express delivery companies as an example, express delivery companies with more advanced operating technologies are equipped with automatic sorting lines, which can sort packages according to their routing information (destination). The automatic sorting line is equipped with weighing equipment and photographing equipment, which are used to collect on-site weight and on-site images when packages are weighed.

[0049] In this embodiment, the on-site weight refers to the weight of a group of packages collected on the scene of the automatic sorting line; the on-site image refers to the image collected on the scene of the automatic sorting line; since the background is inevitably collected at the same time as the image is collected , so the live image will include both the package itself and a part of the live background where the package is located.

[0050] see figure 1 , the following is a detailed introduction to a package quantity detection method disclosed in E...

Embodiment 2

[0065] Embodiment 1 can realize the detection of the quantity of stacked packages in most cases, but there may be room for further improvement of the detection capability in cases of serious stacking. Based on this, Embodiment 2 discloses a package quantity detection method with superior detection capability.

[0066] see figure 2 , a package quantity detection method disclosed in Embodiment 2, which includes steps S10 to S40 in Embodiment 1, the improvement is that steps S50-S60 are also included after step S40:

[0067] S50: If it is recognized that the number of packages is a single piece according to the bounding box information, crop the on-site image based on the bounding box information to obtain a package image.

[0068] With regard to the identification result of the aforementioned step S40, if the number of identified packages is a single piece, it is considered that there may be cases where multiple pieces (packages with serious stacking) are misidentified as a si...

Embodiment 3

[0075] It can be understood that, in Embodiment 1 and Embodiment 2, the target detection model is by default a model that has been trained and matured. And for the training of the target detection model, there are already mature solutions in the prior art. However, Embodiment 3 further discloses a training scheme more suitable for the target detection model involved in the present invention.

[0076] A package quantity detection method disclosed in Embodiment 3 includes any solution of Embodiment 1 or Embodiment 2, that is, on the basis of Embodiment 1 or Embodiment 2, only the training method of the target detection model is improved.

[0077] see image 3 , in this embodiment, the target detection model is used to perform target prediction in step S30 after being trained through the following steps L11-L14:

[0078] L11: Annotate the bounding box information of the parcel in the live image for training.

[0079] Specifically, before the target detection model is officiall...

Abstract

The invention relates to a parcel number detection method and device and a storage medium, and the method comprises the steps: obtaining a field image and the field weight of a group of parcels; searching a corresponding pre-stored weight according to the parcel identification number in the field image; if the on-site weight is not matched with the pre-stored weight, inputting the on-site image into a target detection model for target prediction, and obtaining bounding box information of a package in the on-site image; and identifying the number of the parcels according to the bounding box information. According to the invention, the number of most stacked packages can be detected, so that the accurate weight of the packages can be determined. The method also has the advantages of high detection efficiency and precision and the like.

Description

technical field [0001] The invention relates to the technical field of logistics transportation, in particular to a package quantity detection method, device and storage medium. Background technique [0002] In the logistics and transportation industry, the weight of the package is one of the main basis for charging freight, and inaccurate weight will bring cost losses to the logistics company or customers. Therefore, how to find the wrong weight of the package has become a very important link for the logistics company to recover the freight. [0003] Taking the express delivery industry as an example, the courier needs to weigh the package before receiving the customer's package, and upload the waybill number together with the weighed weight to the background management system; when the package arrives at the express company's automatic sorting line, the sorting Line picking automatically reweighs packages to determine weight. [0004] However, the placement of packages o...
