HDR-I技术应用于光环境性能实测的方法

The Application of HDR-I Technology in Reflecting and Recording the Daylighting Performance

本文研究HDR-I技术用于光环境性能实测的方法流程。通过多曝光时间场景图像的获取、相机亮度反应函数的确定、HDR-I合成、相机刻度校准以及镜头渐晕校准的五步骤技术流程,实现了HDR-I的准确合成,并在合成图片的基础上,利用HDR Scope软件对光环境性能进行分析。解决了光环境动态模拟软件计算时间长,所需环境信息多以及与实际误差大等问题,为光环境实测、评价及软件修正提供技术支持。

The HDR-I technology is used to reflect and record the daylighting performance of real environment. The five steps of the technical procedure are as follows： The exposure time of scene image acquisition,camera brightness response function determination,camera calibration,HDR-I synthesis and lens vignetting calibration. This paper realize the accurate synthesis of HDR-I,and on the basis of image synthesis,daylighting performance was analyzed by HDR Scope software. This resolved the long time calculation,the detailed environment information and the large error of the daylighting simulation. This paper provide technical support for the daylighting environment measurement,evaluation and software correction.
