摘要
本論文主旨在探討研究如何利用時下一般手持PDA設備，對汽車之車牌進行偵測與辨識，系統是開發於Windows Mobile系統平台上。目前影像處理技術大多開發於個人電腦平台上，往往無法使系統輕便化、小型化以及節省成本。而今在全球消費市場及民眾對於智慧型手機正產生越來越濃厚的興趣與需求下，目的就是希望透過微軟程式的開發工具並搭配手持PDA設備，以其輕便及容易使用的特性來實現PDA平台之車牌偵測與辨識系統的開發。 本文之車牌偵測與辨識的方法是透過手持PDA設備內建之Camera將影像作即時靜態擷取，影像經過理後利用Ada-Boosting的 技術來偵測正確車牌的位置，而後將切割出區塊內的車牌字元與資料庫進行相似度的比較，比對之後的結果越接近者則為車牌字元，最後將影像經過修整處理後將辨識結果顯示至螢幕，並做後續相關之應用。

This thesis mainly aims at discussing how to utilize general handheld PDA equipment, detect and recognize to the license plate of the image. The system is developed on Windows Mobile platform. Seeing that the treatment technology of the image is mostly developed on the PC platform, it is unable to make the system miniaturize, melt and save the cost lightly. The purpose is that hopes through the developing tools of Microsoft and cooperates with PDA equipment, easy to use and convenient characteristic transmitted realize that the license plate detection and recognition system. The principle of our system is made up by follow steps, i.e., use PDA capture the picture, pre-processing image, detect and recognize license plate, post-processing image, and finally deliver the result to screen.
