FPGA双线性插值图像变换系统的设计与实现

Design and implementing of image transform system based on FPGA with bilinear arithmetic

运动目标模拟作为一种系统仿真技术是研究图像的检测、跟踪以及图像导引装备的基础技术。该设计通过FPGA对输入图像的实时运算实现对图像的缩放、平移、旋转等变换,并在VGA监视器上显示,为图像识别、跟踪提供背景模拟。在FPGA中实现实时算法使得系统不再依赖DSP进行信号处理,大大降低了成本并缩减了系统体积。

Simulation of moving object, as a simulate technology of system, is the basic technology of researching the image scan and track and guide equipment. This real time system was processing the image on FPGA, achieving a satisfying result of transform, zoom and eddy of the image and display on VCA displayer. The real time processing on FPCA makes the system not depend on DSP. It reduces the cost and curtails the bulk of system.
