Embodiment Construction

[0071] like figure 1 As shown, the present invention discloses a character recognition method suitable for the content of characters printed by dot matrix inkjet equipment, including the following steps:

[0072] Step 1: Obtain the character image to be recognized by the digital imaging device;

[0073]Step 2: Select the corresponding matching template according to the font and font size of the current printing content;

[0074] Step 3: According to the size of the character image to be recognized, the template is enlarged in proportion to form a standard template to be matched;

[0075] Step 4: Scoring the matching degree of each standard template in units of ink droplets;

[0076] Step 5: Accumulate the scores of each point according to the weight to obtain the highest matching score and identify the character to be recognized.

[0077] In said step 2:

[0078] The printing font is dynamically acquired through the interconnection with the front-end coding equipment, so t...

Abstract

The invention provides a character recognition method suitable for character content printed by dot matrix code spraying equipment. The character recognition method comprises the following steps: step 1, acquiring a character image to be recognized by a digital imaging device; 2, selecting a corresponding matching template according to the font and the font size of the current jet printing content; step 3, performing equal-proportion amplification on the template according to the size of the character image to be recognized to form a standard template to be matched; 4, scoring the matching degree of each standard template by taking ink droplets as units; and 5, accumulating the scores of the points according to the weights to obtain the score with the highest matching degree, and identifying the character to be identified. The method has the beneficial effects that 1, aiming at character contents printed by dot matrix code spraying equipment, the recognition speed is high, and the accuracy is high; 2, the requirement on the CPU speed is low, and the hardware purchase cost is saved; and 3, peripheral circuits are few, the board space is saved, and the cost is low.
