Configurable general slope processing method based on FPGA

The invention discloses a configurable general slope processing method based on an FPGA (Field Programmable Gate Array). According to the method, the slope is calculated through parameterized configuration of a sensor target surface, sub-aperture arrangement and sub-aperture size. According to the method, during parameterized configuration of the slope memory module, only a memory space of image width * 2bit is needed, so that the consumption of on-chip resources is greatly reduced, and the stability and robustness of a system are improved. The method is high in portability and can be applied to a plurality of engineering projects. 本发明公开了一种基于FPGA的可配置通用斜率处理方法。该方法通过参数化配置传感器靶面、子孔径排布及子孔径大小来实现斜率的计算。该方法在参数化配置斜率存储器模块时，只需图像宽度*2bit的存储器空间，大大减少了片上资源的耗费，增加了系统的稳定性与鲁棒性。本发明的可移植性高，能够应用于多个工程项目中。
