摘要：
具有摄像功能的手机已经成为一种便捷的二维条码阅读器,但手机因为本身的限制造成拍摄图像模糊,影响了后续的条码识别。本文提出了一种适合在手机平台上的图像盲恢复 方法,以QR码识别为应用目的,利用QR码图像的灰度分布特点,通过模糊图像的边缘响应计算得到PSF函数,再进行图像恢复。实验证明,本文提出的方法具有去模糊效果好、计算简单的特点,适合手机等嵌入式平台的实时应用。
关键词: QR码 去模糊 边缘响应
Abstract:
The mobile phone with a camera is becoming a handy barcode reading device,but because of the limitation of the camera,the captured images are always vague,which makes the result of barcode recognition worse.A blind restoration algorithm is proposed in this paper for the QR barcode on mobile phones.Based on the QR image characteristics,the PSF function is estimated from the edge response of the captured images.The experimental results show this algorithm can get a good deblurring result with a little amount of computation,and is suitable for embedded devices like mobile phones.
Key words: QR barcode;deblurring;edge response
