增进对与珊瑚礁图像有关的光学场景组成部分的了解，将提高利用遥感绘制珊瑚礁地图和监测珊瑚礁的能力。NIST高光谱图像投影仪（HIP）是一种有助于理解这些场景中的组件的工具。在本文中，一个高光谱场景的投影重建使用HIP的第一次解混图像光谱到端元。然后使用NIST HIP投影代表每个端元的丰度图像，并由高光谱成像仪收集。由于场景来自数字源，因此可以重复使用，而无需担心改变测量条件。这项工作代表了开发场景投影功能的第一步，这些功能可用于传感器表征，算法测试或独立更改光学组件，以便更好地了解对整个观察场景的整体影响。
Improving the understanding of the optical scene components associated with coral reef imagery will advance the ability to map and monitor coral reefs using remote sensing. One tool that can aid in understanding the components in these scenes is the NIST Hyperspectral Image Projector (HIP). In this paper a hyperspectral scene is reformatted for projection using the HIP by first unmixing image spectra into endmembers. The abundance images representing each of the endmembers are then projected using the NIST HIP and collected by a hyperspectral imager. Since the scene is from a digital source, it can be used repeatedly without concern for changing measurement conditions. This work represents one of the first steps in developing scene projection capabilities that can be used for sensor characterization, algorithm testing or to have optical components changed independently in order to better understand the overall effects on the total observed scene.
