In order to further improve bill verification accuracy, corresponding classification tree first-order nodes can be established for the plurality of overview pictures according to the overview attribute information, the overview attribute information is matched with the bill attribute information to obtain an attribute matching result, classification tree second-order nodes corresponding to the classification tree first-order nodes are established for the plurality of bill pictures according to the attribute matching result, and preset mapping relations between the overview pictures and the plurality of bill pictures in the plurality of overview pictures are updated based on the classification tree first-order nodes and the classification tree second-order nodes. For example, corresponding classification tree first-order nodes a and b may be respectively established for the plurality of overview pictures according to the overview attribute information, corresponding classification tree second-order nodes a1, a2 and a3 may be established for the plurality of bill pictures according to the attribute matching result, and corresponding classification tree second-order nodes b1, b2 and b3 may be established for the plurality of bill pictures according to the attribute matching result, and then the preset mapping relations between the overview pictures and the plurality of bill pictures in the plurality of overview pictures determined according to the classification tree nodes are the bill pictures corresponding to the nodes a1, a2 and a3 in the overview picture of the node a, and the bill pictures corresponding to the nodes b1, b2 and b3 in the overview picture of the node b.
In addition, in a specific implementation, in order to improve the bill verification accuracy, the following functions can be further provided: upgrading functions: adjusting the invoice into an OA receipt; the degradation function: adjusting the OA bill into an invoice; the upward moving function: move the invoice to the last OA document; the move down function: the invoice is moved to the next OA document. It is easy to understand that the preset mapping relationship between the plurality of overview pictures and the plurality of bill pictures can be optimized through the above functions to improve the bill verification accuracy.
In the embodiment, the images to be identified are identified to obtain a plurality of overview images and a plurality of bill images; traversing the plurality of overview pictures, and taking the traversed overview pictures as the overview pictures to be verified; and screening out the bill picture corresponding to the overview picture to be checked from the plurality of bill pictures according to a preset mapping relation to serve as the bill picture to be checked. Through traversing a plurality of overview pictures, and regard the overview picture that will traverse as waiting to verify the overview picture, then follow according to predetermineeing the mapping relation and select from a plurality of bill pictures with wait to verify the bill picture that the overview picture corresponds as waiting to verify the bill picture to improve the accuracy of the overview picture of waiting to verify that obtains and with wait to verify the bill picture that the overview picture corresponds, further, also improved the accuracy when carrying out the bill verification based on wait to verify the overview picture with wait to verify the bill picture, reduced the bill verification cost, improved office automation degree.
