Abstract

The invention discloses a detection method for intelligently locating a lettering region, belonging to the field of electrics. The detection method specifically comprises the steps of: obtaining and storing the images of the lettering region of a device to be detected; processing the images according to image processing parameters; identifying closed image regions meeting the estimated parameters of the lettering region in the processed images; judging whether letters are obtained by identifying, if so, judging whether the letters obtained by identifying are same as serial numbers stored in the device to be detected, if so, prompting that the internal number and the external number of the device to be detected are the same, otherwise, prompting that the internal number and the external number of the device to be detected are different; and if the letters are not obtained by identifying, judging whether the unidentified closed image regions meeting the estimated parameters of the lettering region exist, if so, continuing to identify, otherwise, detecting the marks of the image processing parameters, adjusting the image processing parameters to reprocess and re-identify the images when the marks are not set, and prompting that the internal number and the external number of the device to be detected are different when the marks are set. The detection method has the beneficial effect that the detection efficiency and the adaptability to light environments are improved.

Description

technical field

[0001] The invention belongs to the field of electricity, and in particular relates to a detection method for intelligently locating lettering areas. Background technique

[0002] When the manufacturer produces information security products such as USB Key, it will set a unique serial number for each USB Key, store it inside the USB Key, and at the same time engrave corresponding lettering on the surface of the product according to the serial number, which often occurs during the production process. There is a problem that the external lettering is inconsistent with the internal serial number. Now manufacturers use manual inspection to see if the external lettering is consistent with the internal serial number, that is, to check whether the internal and external numbers are consistent.

[0003] In the process of realizing the present invention, the inventor found that there are at least the following problems in the prior art: the same manufacturer usually pr...
