Abstract：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.
