In this work, we demonstrate a prototype of a biomimetic multispectral curved compound eye camera (BMCCEC). In comparison with traditional multispectral imaging systems, the BMCCEC developed in this work has the distinct features of multi-spectral imaging on multiple targets in real time in an ultra-large field of view (FOV), which can be attributed to its biomimetic curved compound eye structure as well as the multispectral cluster network. Specifically, the BMCCEC has a total of 104 multispectral ommatidia and a FOV of 98°×98°, which is able to realize 7-band multispectral imaging with center wavelengths of 500 nm, 560 nm, 600 nm, 650 nm, 700 nm, 750 nm and 800 nm and a spectral resolution of 10 nm. A prototype of BMCCEC was then manufactured and multispectral imaging experiments were performed based on it. As a result, the red edge feature of the spectrum of green plants has been successfully obtained and retrieved with a good accuracy.
在这项工作中，我们展示了一种仿生多光谱曲面复眼相机（BMCCEC）的原型。与传统的多光谱成像系统相比，本工作中开发的 BMCCEC 具有在超宽视场（FOV）中实时对多个目标进行多光谱成像的独特功能，这归因于其仿生曲面复眼结构和多光谱聚类网络。具体来说，BMCCEC 共有 104 个多光谱小眼，FOV 为 98°×98°，能够实现中心波长为 500nm、560nm、600nm、650nm、700nm、750nm 和 800nm 的 7 波段多光谱成像，光谱分辨率为 10nm。然后制造了 BMCCEC 的原型，并基于它进行了多光谱成像实验。结果，成功地获得并以良好的精度检索到了植物光谱的红边特征。
