摘要： 高动态范围图像(HDRI)图学技术是利用照相机拍摄不同程度曝光量的照片以获得 最全光亮度信息的技术。非视觉效应影响人体的生理节律，对人类生理和心理健康均起着非常 重要的作用。工业遗产建筑作为特殊建筑类型，如何准确有效的评估建筑空间是否符合非视觉 光环境健康值以及如何改造建筑空间形成更好的光环境具有一定的研究意义。以武汉市平和打 包厂内某建筑作为研究对象，利用 HDRI 图学技术对建筑空间内的非视觉光环境进行评估，结 合仪器实地测量验证光环境问题，并提出相应的建筑空间改造策略。结果证明 HDRI 图学技术 是一种有效的非视觉光环境测量方法，可借此方法研究不同因素对建筑内非视觉健康的影响， 为后续建筑设计及决策提供依据。

Abstract: High dynamic range image (HDRI) graphics is a technique that uses cameras to take photos of a variety of exposure to obtain the maximum brightness. Non-visual effects affect human biorhythm and play a very important role in human physical and mental health. As a special type of building, it is of significance to carry out research on how to accurately and effectively determine whether the building space of the industrial heritage building meets the health value of non-visual light environment and how to transform the building space to shape a better light environment. A building in Pinghe packing factory in Wuhan was taken as the research object, and the non-visual light environment in the building space was evaluated by the HDRI graphics. The on-site measurement and verification of the light environment was conducted with instruments and the corresponding reconstruction strategy of the building space was put forward. The results show that HDRI mapping technology is an effective method of non-visual light environment measurement, which can be used to study the influence of different factors on non-visual health in buildings and provide basis for future architectural design and decision-making.

Key words: high dynamic range image, nonvisual effect, healthy light environment, building space
