Abstract:

The airborne multi-aperture panoramic image compositing technology generates panoramic images with high resolution and rich details by stitching images from multiple sub-aperture or sensors, and plays an important role in many key fields such as national defense and security, agriculture and forestry, and digital surveillance. This paper introduces the development background of airborne multi-aperture panoramic image compositing technology, expounds the basic concepts and steps of panoramic image compositing, sorts out the classification and development of its core technologies--image registration technology and image fusion technology, and summarizes the characteristics and limitations of current mainstream methods. Finally, based on an analysis of the current development status of airborne multi-aperture panoramic image compositing technology, the bottleneck problems of the technology are revealed. The future research directions and possible technical ways to solve these problems are also proposed to provide useful enlightenment for the technological progress and application expansion in this field.

Key words: panoramic image compositing, image registration, image fusion, multi-aperture detection, unmanned aerial vehicle remote sensing
