Verification and Accuracy Check of Luminance and Illuminance Measurements using a Commercial IP Camera Applied as an HDR Vision Sensor

This study verifies and checks the accuracy of luminance and illuminance from high dynamic range images (HDRI) generated by a commercial IP camera compared to measurement devices. The statistical analysis indicates that measuring luminance using the calibration method with a luminance meter is comparable with measurement results using a luminance meter, with average relative error in the range of 5–23%, whereas illuminance measurement using the equation method is in line with the measurement using an illuminance meter, with an average relative error range of 1–11%. Regarding the accuracy of the HDRI method, using digital cameras is in the range of 5–27%, which is still acceptable.
