The Study of the Method on Distribution of Light Source Illuminance Detection That Based on CCD

According to the slow speed, low precision and low efficiency situation of the traditional detection method of the distribution of light illumination, a CCD-based detection method for the distribution of light illumination is proposed, which is based on the study of the illuminometer-based on light detection system. It uses a CCD camera to photograph the light source energy distribution information, using an embedded system as the central processing unit, the light source energy distribution information is transformed into some specific luminosity value through the procession of the system software, by way of the establishment of gray - illumination model, use the illumination value to calibrate the image pixel gray value, access to the situation of the distribution of the illumination light source quickly, that finally to achieve the rapid detection of the distribution of light source illumination.
