Abstract
We developed a proof-of-concept prototype camera-based system for lighting and shading control. The system utilized a simple CMOS-based digital camera with an approximate v-lambda filter, calibrated to provide pixel luminance values up to 10,000 cd/m2. We demonstrated that the single camera sensor has the potential to replace the multiple sensors required by conventional systems for daylight harvesting, shading control, and occupancy sensing. Performance similar to conventional systems was replicated, but in additional, alternate control algorithms based on spatial luminance information were demonstrated. However, considerable further development would be required to produce a commercial version, and there may be resistance to deployment due to privacy issues. Cameras offer other potential valuable end uses, examples are fire detection and security, which could effectively subsidize the lighting control functions, making automatic lighting controls more financially attractive, and promoting energy savings.
