摘要

在靶场测量中，为了得到大视场高分辨率的图像，设计了一套基于DSP的经纬仪实时图像拼接系统，该系统实时采集两个视场传感器的数字图像，在DSP内部实现图像的自动拼接，将拼接后的图像以标准数字格式输出，供后续系统使用。文章给出了图像拼接系统的硬件组成原理，该系统的两个图像传感器的帧频为100 Hz，传统图像拼接算法无法满足实时性的要求，为此提出了一种基于相位相关法确定相似区域的图像拼接算法，并进行了实时图像拼接实验，结果表明，优化方法的图像拼接速度平均为7 ms，满足实时性的要求，实现了图像的无缝拼接，同时系统稳定可靠，满足靶场测量的实际要求。

Abstract

In the range

in order to get the image of wide field of view and high resolution

the real-time image-mosaic system based on DSP was designed. The system obtain image of two field of view sensor

and then mosaic within the DSP. At last

the standard numeric format was exported for other systems. The hardware principle of image mosaic-system was given. As the frame rate of the two sensors was 100 Hz

the traditional image mosaic algorithm cannot satisfy the real-time requirement. So the phase correlation algorithm was used to determine the similar area to reduce time for mosaic image. The experiment was taken. The result showed that the time for real-time image mosaic was average 7 ms

which meets the real-time requirements. The system is stable and reliable

which meets the practical requirements of range measurement.
