An image preprocessing method based on field-programmable gate array (FPGA) monitoring and USB3.0 transmission was presented to improve the transmission speed of the original USB2.0 interface technology of the camera in order to promote the industrial application of civil camera. The powerful parallel computing ability of FPGA was used under the condition of preserving the structure of the comera. The real-time acquisition and preprocessing of image data could be conducted through the external monitor. Then the pretreatment results could be fast communicated with host computer by USB3.0 interface, which could greatly save the image transmission time. At the same time, a part of preprocessing work was finished in hardware. The goal of obtaining the normalized image fast was achieved. The design idea and structure of the system were introduced in detail. The examination and experimental data were respectively verified by the software and the hardware. The experimental results indicate that the system has the characteristics of friendly interface, stable performance, high integration, flexible use and strong practicability.
