摘　　要：传统的QR码识别算法只适用于平面上的条码,柱面上的条码由于二维及三维空间均发生畸变,识别率很低。本文提出一种方法,在背景相对清晰的场合下,通过添加平行于QR码外侧轮廓的辅助矩形进行二维平面校正。在获得平面校正的图像后,再利用效率相对较高的区域还原算法进行三维空间校正,最终获得校正后的图像。该方法在Android平台上进行实现。结果表明,对柱面QR码的识别有较高的准确率。Traditional QR code recognition algorithm is usually applied to the barcode printed on flat surface only, the barcode on cylinder, because of the distortion of 2D and 3D space, the recognition rate is low.The paper proposes a new method by adding auxiliary rectangles which is parallel to QR code outer contour for 2D space correction when the background is relatively clear.Af-ter getting the 2D correction image, using area reduction for 3D space correction, it is implemented on the Android platform.The result shows this method has high recognition rate.
