本發明係關於一種二維碼讀取系統及方法，特別是關於一種微型二維碼讀取系統及方法。The present invention relates to a two-dimensional code reading system and method, in particular to a miniature two-dimensional code reading system and method.

在現代人的生活中，購買商品及管理物料經常利用條碼幫助記錄品項及計算數量。隨著科技的進步，條碼不再只是黑白相間的長條狀排列，更因資訊量的提升，而發展出二維碼，且因應用領域的差異，上述二維碼更可進一步區分成數據矩陣(data matrix)、QR碼、PDF417碼等形式。In the life of modern people, when purchasing goods and managing materials, barcodes are often used to help record items and calculate quantities. With the advancement of science and technology, barcodes are no longer just black and white long strips, but due to the increase in the amount of information, two-dimensional codes have been developed, and due to differences in application fields, the above two-dimensional codes can be further divided into data matrix (data matrix), QR code, PDF417 code, etc.

除此之外，由於二維碼可記錄許多商品及物料資訊，因此近年來，許多商品的外包裝上已利用二維碼進行產品資訊的標示，甚至在部分物料的表面也發現利用二維碼進行物料資訊的標示。In addition, because QR codes can record a lot of product and material information, in recent years, the outer packaging of many commodities has used QR codes to mark product information, and even the use of QR codes has been found on the surface of some materials.

When the size of the two-dimensional code is smaller than the recognition limit value of the general code reader, the general code reader will not be able to directly recognize and read the extremely small size of the miniature two-dimensional code. Therefore, there is an urgent need for a novel reading system and method for miniature two-dimensional codes.
