Abstract
In recent years, the availability of video-cameras with CCD-type sensors (Charge Coupled Device) has given considerable impulse to the use of videography system for all applications requiring photometric measurements, above all the luminance evaluation. With reference to the measurement of luminance in a built-up environment, this method is particularly interesting because it allows the instantaneous capture of an image, thereby obtaining luminance values relating to different points of measurement.
In this paper, a brief description of this acquisition system is reported and then a report on the procedure adopted for its calibration with a zoom and a fish-eye lens is presented. Finally, with reference to an office application, a case study on videoluminancemeter potentiality features in the built environment is reported; the results are compared with values obtained using a traditional luminancemeter, and the potentiality of video-camera in the assessment of Italian standard prescription is shown too.
