摘要
随着现代科技的高速发展,一些高新领域要求智能相机具备一维条码的高速解读功能,其关键技术是一维条码的自适应快速定位。为了更快速地进行复杂背景和倾斜、破损情况下条码定位,提出了一种应用于智能相机的新方法。该方法的基本原理是基于DSP运算特征的条码形态学特征分析,利用基于DSP的快速区域分析算法得到区域特征,并通过筛选和扫描完成最终的定位。据我们所知,将基于DSP的快速区域分析算法应用于智能相机,为一维条码的高速解读奠定了坚实的技术支撑,在国内还未见报道。
Along with the rapid development of science and technology, some high-tech fields need high-speed smart cameras which have a dimensional barcode reading function with high speed. And the key technology is rapid adaptive positioning for one dimensional bareode. A novel method which is applied in smart cameras while can quickly complete barcode location in complex background and tilt, damage cases is proposed in this paper. The basic principle of this method is based on the morphology analysis of barcode. At the same time, considering for the architecture of DSP, the regional characteristics are obtained by employing fast area analysis algorithm and the final positioning is completed through screening and scanning in the proposed method. To the best of our knowledge, the fast area analysis algorithm on DSP which is applied in the smart cameras has not been reported and laid a solid technical foundation for a dimensional barcode reading with high-speed.
