【摘要】 Hough变换、曲面拟合背景去除、控制点变换等方法是QR码识别应用中图像预处理的重要方法,针对图像预处理后图像的识别率比较低缺点,提出了一种基于邻域标记法的QR码识别方法。利用模板邻域标记QR码,对邻域标记进行阈值的处理得出取样网格。实践表明,本文算法能有效的提高QR码的识别效率和效果。更多还原

【Abstract】 Hough transformation,surface-fitting removing background and control point transformation are the essential methods of image preprocessing in QR code application.An improved QR code recognition method based on the neighborhood mark was proposed in this paper to improve the low efficiency of the image recognition after image preprocessing.A template was used to match with QR code image,the neighborhood mark image was obtained easily. Then,a selected threshold was processed the neighborhood mark and the sample grid image was obtained.The simulated results proved that the QR code recognition efficiency and the effect were improved.更多还原
