Embodiment 1
[0045] Such as figure 2 As shown, the license plate recognition intelligent error correction method provided by the embodiment of the present invention is applied to the data collection server, and the method includes the following steps:
[0046] S101. Obtain the recognized license plate after receiving the vehicle passing record.
[0047] Specifically, the data collection server records each vehicle passing, and obtains the license plate number recognized by the camera or the video analysis server.
[0048] S102. Compare and analyze the recognized license plate with the preset camera license plate character credibility rule table in the database, and calculate the credibility of the recognized license plate, the suspected license plate and the credibility of the suspected license plate.
[0049] see image 3 , this step S40 further includes:
[0050] S1021. For each character of the license plate, according to the character and the position where the character appears, que...
Embodiment 2
[0063] Such as Figure 6 As shown, the license plate recognition intelligent error correction method provided by the preferred embodiment of the present invention includes the following steps:
[0064] S10. A table of pre-set license plate character credibility rules.
[0065] Specifically, this step S10 further includes: presetting a global license plate character credibility rule table in the database; setting a camera license plate character credibility rule table in the database.
[0066] Among them, the global license plate character credibility rule table (such as Figure 4 ) includes fields: license plate characters, character appearance positions, credibility, suspected characters and the credibility of suspected characters. The initial data comes from the long-term statistical conclusions of the license plate recognition camera models that have been put into production, and can be counted manually, or using a professional statistical tools. If manual statistics are...
Embodiment 3
[0089] Such as Figure 7 As shown, a license plate recognition intelligent error correction system provided by a preferred embodiment of the present invention includes a license plate acquisition module 10, a calculation module 20, a storage module 30, a query module 40, a feedback module 50 and a correction module 60, wherein:
[0090] The license plate acquisition module 10 is used to obtain the recognized license plate after receiving the vehicle passing record;
[0091] Calculation module 20 is used to compare and analyze the recognized license plate with the camera license plate character credibility rule table set by the database, and calculate the credibility of the identified license plate, the suspected license plate of the license plate and the credibility of the suspected license plate;
[0092] Preferably, the calculation module 20 includes a first calculation unit 201 and a second calculation unit 202, wherein:
[0093] The first calculating unit 201 is used for ...
