Problems solved by technology

[0002] In the prior art, the license plate number recognition is generally carried out by taking the license plate and then manually identifying it. In this way, the point acquisition itself becomes one of the technical difficulties. The solution in the prior art is to use the license plate fixing nail of special material , but this method obviously brings too high social costs, and there is too much room for power rent-seeking in the implementation process, and at the same time, the way of manual identification also brings too high labor costs

Embodiment Construction

[0016] The technical solution of the present invention is further described below, but the scope of protection is not limited to the description.

[0017] Such as figure 1 A kind of license plate number recognition method based on data model shown, comprises the following steps:

[0018] a. Model building: through historical data, establish a data model of dot matrix color difference → character recognition and color selection range → recognition result, and establish a possibility evaluation model for each possible recognition result;

[0019] b. Obtaining data: read the current image data to be recognized from the cache library to be recognized to the memory, and select five image bitmap data with the highest possibility of recognition according to the color selection range→recognition result model, and store the image bitmap data Sort by the recognition possibility of the recognition results from high to low;

[0020] c. Character recognition: For the highest-ordered imag...

Abstract

The invention provides a license plate number recognition method based on a data model. The license plate number recognition method comprises the following steps that a. a model is established; b. data are acquired; c. character bits are recognized; d. possibility assessment is performed; and e. the result is obtained. Using of license plate fixing nails of special material can be avoided to a great extent through the mode of color range screening, character bit recognition and possibility assessment with no requirement for artificial recognition so that labor cost can be greatly reduced.

Description

technical field [0001] The invention relates to a vehicle plate number recognition method based on a data model. Background technique [0002] In the prior art, the license plate number recognition is generally carried out by taking the license plate and then manually identifying it. In this way, the point acquisition itself becomes one of the technical difficulties. The solution in the prior art is to use the license plate fixing nail of special material , but this method obviously brings too high social costs, and there is too much room for power rent-seeking in the implementation process, and the manual identification method also brings too high labor costs. Contents of the invention [0003] In order to solve the above technical problems, the present invention provides a data model-based license plate number recognition method, the data model-based license plate number recognition method can be used in a large To a certain extent, the use of license plate fixing nails...
