A secure data transmission method based on batch two-dimensional code transmission

The invention relates to a secure data transmission method based on batch two-dimensional code transmission. The whole picture of a display screen is collected at one time, and a plurality of two-dimensional code pictures in the pictures are divided by using an image segmentation technology, and then a single two-dimensional code picture is recognized in turn. This method can greatly improve the transmission bandwidth by transmitting multiple QR codes at one time under the circumstance of little change to the hardware environment conditions. 种基于批量二维码传输的安全数据传输方法，通过次性采集显示屏幕整张照片，利用图像分割技术将照片中的多张二维码图片分割出来，再依次对单张二维码图片进行识别。这种方式在对硬件设备环境条件改变不大的情况下，次传输多个二维码，可以大幅提升传输带宽。
