一种外置条码识读设备及识读方法An external barcode reading device and reading method

技术领域technical field

本发明涉及条码识读领域，具体地说涉及一种外置条码识读设备及识读方法。The invention relates to the field of barcode reading, in particular to an external barcode reading device and a reading method.

背景技术Background technique

条码识读设备指的是用来读取条码信息的设备。它使用一个光学装置将条码的条空信息转换，成电子信息，再由专用译码器翻译成相应的数据信息。因其输入速度快、可靠性高、采集信息量大、灵活实用的有点，在商品流通、图书管理、邮电管理、银行系统等许多领域上，条码识读设备都得到了广泛的应用。Barcode reading equipment refers to equipment used to read barcode information. It uses an optical device to convert the space information of the bar code into electronic information, and then translates it into corresponding data information by a dedicated decoder. Because of its fast input speed, high reliability, large amount of collected information, and flexible and practical features, barcode reading equipment has been widely used in many fields such as commodity circulation, book management, post and telecommunications management, and banking systems.

条码识读设备因为具有优化的专业识读算法，识读效率高，且能适应不同的使用场景，不过此类设备成本较高，所以在一些非典型领域的从业人员因为扫码频率不高，且受限于采购预算等情况，普遍采用个人或工作手机作为识读条码的手段。但普通手机所安装的各类条码识读软件采用开源算法，仅能识别条件良好的条码，且识读速度低，长时间通过亮屏扫码影响手机续航。尤其面对折皱，污损，畸变等复杂情况的条码时，甚至无法完成识别。Because of the optimized professional reading algorithm, the barcode reading equipment has high reading efficiency and can adapt to different usage scenarios. However, the cost of such equipment is relatively high, so practitioners in some atypical fields do not scan codes frequently. And limited by the procurement budget and other circumstances, personal or work mobile phones are generally used as a means of reading barcodes. However, all kinds of barcode reading software installed on ordinary mobile phones use open source algorithms, which can only recognize barcodes with good conditions, and the reading speed is low, and scanning codes with bright screens for a long time will affect the battery life of mobile phones. Especially when faced with complex barcodes such as wrinkles, stains, and distortions, it is even impossible to complete the recognition.
