The recording of high resolution spectral images and non-invasive monitoring of wall paintings in grotto sites, tombs and buildings are particularly important since these paintings are extremely vulnerable. The remoteness of some of the sites, the inaccessible height of some of the paintings and the difficulty in controlling the environment they are in, all contribute to their vulnerability. Imaging of wall paintings at high resolution currently requires either scaffolding or some heavy and cumbersome mechanical structure to lift the camera to the upper parts of a wall or ceiling. The aim of the proposed project is to develop a portable imaging system that is light-weight and flexible for in situ high resolution, accurate colour and spectral imaging in the visible/near infrared (400-1000nm) and short-wave infrared (900nm-1700nm), including fluorescence imaging of wall paintings and other large paintings from ground level. The system would provide the means of non-invasive monitoring of the conditions of the paintings, revealing past intervention, studying painting techniques and identifying pigments and disseminating the 3D colour images to the general public. The portability of the system means that it can be taken to remote sites to image paintings in situ without the need for scaffolding or other cumbersome mechanical structures and that it can also be used to image large museum paintings and painted objects in situ at high resolution.

高分辨率光谱图像的记录和石窟遗址、墓葬和建筑物壁画的非侵入性监测特别重要，因为这些壁画极其脆弱。一些地点的偏远，一些画作的高度难以接近，以及难以控制它们所处的环境，都导致了它们的脆弱性。以高分辨率对壁画进行成像目前需要脚手架或一些笨重的机械结构来将相机提升到墙壁或天花板的上部。拟议项目的目的是开发一种轻便灵活的便携式成像系统，用于在可见/近红外（400- 1000纳米）和短波红外（900 - 1700纳米）进行现场高分辨率、准确的彩色和光谱成像，包括从地面对壁画和其他大型绘画进行荧光成像。该系统将提供非侵入性监测绘画状况的手段，揭示过去的干预，研究绘画技术和识别颜料，并向公众传播3D彩色图像。该系统的便携性意味着它可以被带到远程站点，在现场对绘画进行成像，而不需要脚手架或其他笨重的机械结构，并且它也可以用于以高分辨率对大型博物馆绘画和绘画对象进行成像。
