摘要註:	財政部為了防止逃漏稅，於民國77 年11 月開始施行統一發票給獎辦法，鼓勵民眾拿取發票來增加額外的收入，許多的慈善團體也將募集發票視為一個重要的財源，但人工逐一目視對獎發票的動作相當單調。將兩個月所累積下來的發票總量與多組中獎數字進行交叉比對，耗時又耗力。如果透過電腦能將對獎的流程一貫化，則可大幅的降低使用者的負擔。本論文所研究之統一發票自動對獎系統(automatic invoice winning system )使用階層式模組化C 語言搭配OpenCV 函式庫(Open Source Computer Vision Library)，實現於一般的家用個人電腦。針對各種不同的角度、光線，還有各種不同深淺樣式浮水印的發票情形，利用一般家用的USB 個人電腦攝影機(PC Camera)，搭配簡單的背景，以影像處理的方式自動偵測目標發票，並辨識出發票上的對獎數字，將對獎的動作變成由電腦執行影像辨識的一貫化的流程。實驗結果顯示系統可以每秒27 偵的速度進行即時發票自動偵測，並容許360 度的任意歪斜角度，98.63%的高精準度能正確的篩選出各種顏色與紋路的浮水印背景下的中獎發票，每一張發票由取像到辨識出數字平均運算時間為114ms，達到提升對獎的效率與降低人力消耗的目標。 In order to prevent the tax invasion problem for the Ministry of finance, they encouraged people to receive the invoice to established extra incomes from the beginning of the rewarding method of uniform invoice a in November, 77 in Republic of China. That is also one of the most important financial resources for many charitable organizations. However, check the award-winning list one by one in artificial was pretty monotone. It’s not only time-consuming but also tedious for the cross match between the totally invoice accumulated in two months and many pair of award-winning numbers. If we can make the procedure consistent in checking number through computers, that could lower the user’s burden in speed step. The automatic invoice winning system in this theory with Open Source Computer Vision Library was used in personal computer. To every kinds of counters, including angles, lights, and different types of watermarks, it make good used of computer USB and PC Camera of personal computer with simple background. The way of using image-processing to auto-detect the target receipt, and distinguish the compared number on the receipt has made the reward-checking become a constant process of visual distinguishing done by computer. The experiment has showed out that the system can processing the receipt immediately at the speed of 27 frames per second, 360 degree of willful angle allowed, and with the 98.63 percent of high precision can select any kind of color and vein under the watermark’s background of the winning ticket; each of the receipt’s average time of calculation from vision-selection to distinguish the number is 114 ms, achieving the goal of lifting efficiency while checking ticket and lower the consumption of personal.
