摘要

通过HDR(高动态范围)亮度捕获来计算基于视场亮度的度量，以评估真实场景中眩光造成的视觉不适，通常需要使用广角鱼眼镜头。本文提出了一种易于实现和低成本的估算鱼眼透镜总视场的方法和投影方法，这是准确评估眩光所必需的。

A METHOD FOR ESTIMATING FISHEYE LENS’ FIELD-OF-VIEW ANGLE AND PROJECTION FOR HDR LUMINANCE CAPTURE

The calculation of field-of-view luminance based metrics for visual discomfort from glare evaluation in real scenes via HDR (High Dynamic Range) luminance capture does generally require the use of wide view fisheye lenses. This paper presents an easy to implement and low-cost method to estimate a fisheye lens’ total field-of view and projection method, which is required for accurate glare evaluations.
