相位相关红外图像配准算法的硬件实现

Hardware Implementation of Phase Correlation Infrared Image Registration Algorithm

摘要:

在目前图像配准算法中，相位相关法是相对比较成熟的，并且有较多的改进算法，但是随着算法的复杂度增加，相应的运算量也增加，那么在保证效果的同时实时性却无法保证。根据这一现状，提出了在FPGA中实现相位相关法配准技术。在以FPGA为主处理芯片搭建的平台上，利用光纤高速传输图像，实现并且验证了相位相关法的可行性。详细阐述了相位相关法在FPGA中实现的主要步骤。结果表明，相位相关法能在FPGA中实现，并能充分利用FPGA的并行性和资源多的优点，使得处理算法的时间缩短，可以满足实时性要求。

Abstract:

The method of phase correlation is relatively mature in current image registration algorithms. But as the increase of algorithm complexity, the calculation is increasing correspondingly, and the real-time performance can not be assured. Based on this situation, a registration technology of phase correlation method is proposed based on FPGA. In the hardware system of FPGA, this method will be realized and verified by transferring images with the high-speed fiber, and its main steps will be expounded in the paper. The conclusion shows that the phase correlation method can be realized in FPGA, and can make full use of the advantages of parallelism and rich resources of FPGA. Besides, the processing time is shortened, and can meet the real-time requirement.
