基于图像插值的电视测角仪视场变换系统设计

TV goniometer size field transform system design based on cubic interpolation

某型装备电视测角仪给检测仪提供电视信号的同时还需要对电视信号进行控制,以进行大小视场的变换,选用双三次插值法来实现视场变换的效果,并根据实际需要设计了查表模块来代替复杂的权值计算,以便节约FPGA系统资源。完成了系统硬件设计,最后设计了FPGA图像插值的各个模块,完成设计。

TV goniometer provides television signals to detector, at the same time also need to control the zoom television sig- nals,for the size of the view of transformation. This paper selects the double three interpolation method to realize the view transfor- mation effect, and improves the algorithm according to the actual needs, in order to save the FPGA system resources. Complete the system hardware design and the design flow of each module. FPGA image interpolation is used to complete the design.
