Although the existing automatic sorting system has high sorting efficiency, even tens of thousands of sorting machines per hour, the automatic sorting system has high price and large occupied area. And the express delivery station in the city is the last station for delivering the express, and the courier takes the express from the delivery station and then directly delivers the express to the receiver. The large number of distribution stations, small area, small number of personnel, etc., make the automated sorting system not suitable for the distribution stations.
At present, manual sorting is generally adopted in express delivery stations of cities, express packages are distributed to different road areas, and each express delivery person is responsible for express delivery in a plurality of road areas. The road block refers to that an express company subdivides an administrative area of a city into a plurality of small blocks for facilitating the receiving and transmitting of express, so that the receiving and transmitting work of the express is facilitated. In general, since the manual sorting is easy to make mistakes, in order to avoid mistakes, the courier needs to check once again after taking the package to be dispatched, so that the sorting of the express in the delivery station needs to consume large manpower and material resources. Especially when promoting to each big sales site, the distribution station relies on the mode of manual sorting, and inefficiency, the higher problem of error rate will be more outstanding to greatly influence the dispatch efficiency of express delivery.

The method of identifying the way region values will be described in detail later.
In this embodiment, the control method further includes: and transmitting the express package to a sub-conveyor belt corresponding to the road zone value according to the road zone value of the express package.
In this embodiment, transmitting the express package to the sub-conveyor belt corresponding to the road zone value according to the road zone value of the express package includes: and controlling the position state of the swing rod according to the road area value to enable the express package to move to the sub-conveyor belt corresponding to the road area value. Specifically, after the express package 110 enters one sub-conveyor 160, the swing rod 410 is controlled to swing to an inclined position, and the express package 110 cannot advance when being transferred to the position where the swing rod 410 is located, so as to move obliquely along the swing rod 410 and enter the next sub-conveyor 160.
In some embodiments of the present invention, other sorting methods may be used, and the present invention is not limited thereto.
Fig. 6 is a schematic flow chart of identifying an image add-on value in an embodiment of the invention. Identifying the way region value on the image includes the following steps.
In step S601, an express delivery face sheet image on the images of the side and bottom of the express delivery package is acquired based on the edge detection method. Specifically, the segmentation method based on edge detection can directly segment the express delivery face list on the image, and the express delivery face list is imaged and then grayed, so that preparation is made for subsequent edge detection. The edge detection method adopts the Canny technology to ensure good edge intensity estimation, and can resist noise to a certain extent and keep weak edges.
In step S602, characters on the express delivery side sheet image are identified through the dilation-erosion process according to the express delivery side sheet image. Specifically, the similar image areas are connected by the expansion process, and isolated and fine color patches are removed by the etching process. All characters on the express bill are communicated, so that preparation is made for selecting a road area through contour recognition.
In step S603, a road region character is obtained by contour recognition from the character. Specifically, binarization processing is used in the step to strengthen sharp edges and further remove useless information in the image.
In step S604, vector calculation is performed on the road region characters to obtain a character array. Specifically, the express bill image is copied again, and vector calculation is performed. Then, the horizontal mapping and the vertical mapping pixels are used for carrying out pixel level segmentation on the road area character, when the number of pixels with the pixel value larger than 0 in each column exceeds 5, the column is considered to be digital, whether the pixels in each column are larger than 5 is recorded, an array is generated, and the value of the array is the character array identified by final segmentation.
In step S605, the numeric value of the character array is obtained as the road area value of the express delivery by calculation.
The method for identifying the road area value on the image in the embodiment of the invention can effectively identify the road area value on the image of the express package 110 shot by the first imager 220, and ensure that the express package 110 is comprehensively and accurately sorted according to the road area value.
