基于SOC的高实时全景拼接技术研究

Research on high real-time panoramic mosaic technology based on SOC

随着光电侦察技术的不断发展与更新,人们对信号处理单元的计算能力、传输速率、实时性都提出了更高的要求。为快速获取侦察态势信息,进一步提高敏感信息的捕获速度,要求在更短时间内实现全景图像的拼接,但采用传统的“DSP+FPGA”实现方法难以满足实时性要求。因此,本文在对全景拼接技术进行深入研究的基础上,利用异构SOC的并行计算特点,实现了一种高实时性的全景拼接。

With the development of photoelectric reconnaissance technology,higher requirements are put forward for the computing capacity,transmission rate and real-time performance of signal processing unit.To quick reconnaissance situational information,further improve the capture speed of sensitive information,the panoramic image is required in a shorter time,but the traditional“DSP+FPGA”realization method of real time is difficult to meet the requirements.Therefore,based on the technology of panoramic stitching on the basis of in-depth study,using heterogeneous paraller computing characteristics of soc is superior,we implement a high real-time panoramic stitching.
