Invoice Code Recognition System Based on FPGA Acceleration

Aiming at the problem of invoice code identification, this article focuses on the embedded system for identifying invoice codes. FPGA has the characteristics of large data throughput, flexible development, and high real-time performance in image processing. Therefore, based on the DE10- LITE development board, this article mounts an FPGA hardware accelerator in the ARM soft core. An invoice code identification system was built through the method of software and hardware collaborative design. The hardware realizes image data acquisition, preprocessing and other functions, and the software part realizes the function of projection segmentation and recognition. Meanwhile, the different coupling modes of accelerator in the heterogeneous system are compared with each other. The verification results on the hardware development platform show that the system could quickly and accurately identify the invoice code.
