judging whether the feature matching result is smaller than a preset matching result or not;
if the characteristic matching result is smaller than a preset matching result, updating the characteristic information of the target ship to be confirmed to the characteristic information of the ship data to generate a ship characteristic database, and extracting and outputting the corresponding target ship to be confirmed according to the characteristic information of the target ship to be confirmed and marking the target ship to be confirmed as a newly-added target ship;
and if the characteristic matching result is greater than or equal to a preset matching result, outputting the image data of the target ship to be confirmed.
7. An apparatus for confirming a newly added target vessel, comprising:
the first acquisition module is used for acquiring ship image data stored in the electronic purse net information storage system;
the database generation module is used for extracting the characteristic information of ship data based on the ship image data and generating a ship characteristic database from the characteristic information of the ship data;
the second acquisition module is used for acquiring the image data of the target ship to be confirmed in the electronic purse net and extracting the characteristic information of the target ship to be confirmed from the image data of the target ship to be confirmed;
the matching module is used for generating a ship characteristic database by the characteristic information of the target ship to be confirmed and the characteristic information of the ship data for matching to obtain a characteristic matching result;
and the output module is used for confirming and outputting the newly added target ship according to the characteristic matching result.
8. The apparatus of claim 7, further comprising:
the splitting module is used for splitting the ship image data into ship images;
the classification module is used for extracting ship features in the ship images based on the ship images and classifying according to the ship features to obtain at least one class of ship feature classification results;
the setting module is used for correspondingly setting category codes according to at least one category of ship feature classification results;
and the classification module is used for indexing the class codes and the ship feature classification results to generate a ship feature classification result index table.
9. An electronic device, comprising:
a memory and a processor communicatively coupled to each other, the memory having stored therein computer instructions, the processor executing the computer instructions to perform the method of validating a newly added target vessel as claimed in any one of claims 1 to 6.
10. A computer-readable storage medium storing computer instructions for causing a computer to perform the method of validation of a newly added target vessel of any of claims 1-6.
