Abstract

The present disclosure provides a visual identification system and a classifying and sorting system. The visual identification system includes: a material information identification device, configured to identify material information of an item in a circulation box; a server, configured to store a plurality of material templates for a plurality of items; receive the identified material information from the material information identification device via a network; retrieve a material template corresponding to the identified material information from the plurality of material templates; and send the retrieved material template to a photography device; and the photography device, configured to capture an image of the item conveyed into a photography area; receive the material template from the server via the network; and match the captured image with the received material template to determine position information of the item in the circulation box, the position information being used for sorting the item from the circulation box.

First claim

We claim:

1. A visual identification system, comprising:
a material information identification device, configured to identify material information of an item in a circulation box;
a server, configured to store a plurality of material templates for a plurality of items;
receive the identified material information from the material information identification device via a network; retrieve a material template corresponding to the identified material information from the plurality of material templates; and send the retrieved material template to a photography device; and
the photography device, configured to capture an image of the item conveyed into a photography area; receive the material template from the server via the network; and match the captured image with the received material template to determine position information of the item in the circulation box, the position information being used for sorting the item from the circulation box.

2. The visual identification system of claim 1 , wherein the material information identification device comprises an RFID radio frequency identification device, the RFID radio frequency identification device comprising a RFID tag attached to the circulation box and a RFID reader mounted at a predetermined position.

3. The visual identification system of claim 1 , wherein the network comprises an Ethernet.

4. The visual identification system of claim 1 , further comprising:
a conveying device, wherein a circulation box is placed on the conveying device so as to be conveyed along a pipeline, and an item to be sorted is placed in the circulation box;
a sorting device, configured to receive the determined position information from the photography device via the network; and sort the item from the circulation box according to the received position information when the circulation box is conveyed to a sorting area.

5. The visual identification system of claim 4 , further comprising: an encoder configured to calculate an offset of the item from the photography area to the sorting area, and encode the offset, and
the sorting device is further configured to calculate the position information of the item according to the encoding of the encoder to perform the sorting.

6. A visual identification method, comprising:
identifying material information of an item in a circulation box;
retrieving a material template corresponding to the identified material information from a stored plurality of material templates for a plurality of items according to the identified material information;
capturing an image of the item conveyed into a photography area; and
matching the captured image with the retrieved material template to determine position information of the item in the circulation box, the position information being used for sorting the item from the circulation box.

7. The visual identification method of claim 6 , further comprising:
sorting the item from the circulation box according to the determined position information when the circulation box is conveyed to a sorting area.

8. The visual identification method of claim 6 , further comprising: calculating an offset of the item from the photography area to the sorting area, encoding the offset, and calculating the position information of the item according to the encoding to perform the sorting.

9. A visual identification system, comprising:
a material information identification device, configured to identify material information of an item in a circulation box;
a photography device, configured to capture an image of the item conveyed into a photography area;
a processor; and
a memory storing computer executable instructions that, when executed by the processor, cause the processor to:
retrieve a material template corresponding to the identified material information from a stored plurality of material templates for a plurality of items according to the identified material information; and
match the captured image with the retrieved material template to determine position information of the item in the circulation box, the position information being used for sorting the item from the circulation box.

10. The visual identification system of claim 9 , wherein the material information identification device comprises an RFID radio frequency identification device, the RFID radio frequency identification device comprising a RFID tag attached to the circulation box and a RFID reader mounted at a predetermined position.

11. The visual identification system of claim 9 , further comprising:
a conveying device, wherein a circulation box is placed on the conveying device so as to be conveyed along a pipeline, and an item to be sorted is placed in the circulation box; and
a sorting device, configured to receive the determined position information from the photography device via a network; and sort the item from the circulation box according to the received position information when the circulation box is conveyed to a sorting area.

12. The visual identification system of claim 9 , wherein the instructions that, when executed by the processor, further cause the processor to:
calculate an offset of the item from the photography area to the sorting area, encoding the offset, and calculate the position information of the item according to the encoding to perform the sorting.

13. The visual identification system of claim 9 , wherein the instructions that, when executed by the processor, further cause the processor to calculate an offset of the item from the photography area to the sorting area, and encode the offset, and
the sorting device is further configured to calculate the position information of the item according to the encoding of the encoder to perform the sorting.
