Aiming at the need of calibration detection of array camera, a radiometric calibration device of multi-light source array camera is developed in this work. By calculating the attenuation efficiency of the integrating sphere and testing the attenuation curve of the optical energy, the optical transfer curve of the system can be obtained. It employs a wide range measuring device to realize the real-time measurement of the system's light intensity change, and uses a variety of light sources combined with the attenuating wheel set to achieve the continuous output of the test light source with a wide dynamic range of 1.728×10-5~54Lux, respectively to meet the multi-parameter detection requirements of low-light array camera, high-light array camera and other array cameras. Finally, the multi-parameter detection experiment and calibration analysis of array camera are carried out in this work. The experimental results show that the device in this paper can realize real-time monitoring of illuminance characteristics and detect the quality of various array cameras for a long time, and can determine the operating environment and use scope of array cameras.
