摘要：身份證是我國滿十八歲的成年人有效的識別身份的證件，上面記錄了擁有者的基本身份信息以及唯一的身份證十八位編碼。在目前大多數情況下，身份證錄入都采用了人工方式，這種方式是很不方便的。但是，隨著計算機處理技術的高速發展以及數字定位、識別算法的進一步成熟，從而使用計算進行身份證的自動快速識別已經成為了可能。身份證自動快速識別系統可以廣泛應用于國內各個行業，還能節約大量的人力物力，具有廣泛的應用前景。

　　本文通過對身份證的識別提出了詳細的本系統的流程處理：圖像灰度化、預處理、二值化、去噪、數字定位、模版匹配及識別。該流程處理的基本原理在于：先將身份證通過具有攝像功能的儀器掃描到計算機里，然后對需要處理的身份證照片進行圖像數字化，對所取得的數字圖像進行處理，從而定位并識別出我們所需要的身份證編號，進一步達到識別身份的目的。實驗結果表明，采用該身份證自動快速識別系統可取得較好的效果。

ABSTRACT：ID card of adults aged 18 and valid identity documents, the above records the owner's basic identity information and a unique identification eighteen coded. In most cases, the current, ID cards have adopted a manual input mode, which is very convenient. However, with the rapid development of computer processing technology and digital positioning, recognition algorithm to mature in order to use the automatic calculation for rapid identification card has become possible. Automatic identification system can be widely used to quickly identify all industries, but also save a lot of manpower and resources, has a broad application prospects.

　　Based on the identification card presented a detailed process flow of the system: gray image pre-processing, binarization, denoising, digital positioning, template matching and recognition. The basic principle is that workflow process: first identity through having an imaging function instrument scanned into the computer, then the need for photo ID card for image processing of digitized the acquired digital image processing to locate and identify our identification no need to further achieve the purpose of identity. The experimental results show that this identity automatic rapid identification system can achieve better results.
