In order to enhance the control of the dynamic light source, the position and illuminance control system of the dynamic light source is designed by using the LabVIEW dynamic light source proportional-integral-differential (PID) control method. The system changes the position of the light source by controlling the motor, and changes the illumination of the dynamic light source by controlling the output current through the PID control and parameter self-tuning module of the programming software LabVIEW. The research shows that the system can effectively control the position and illumination of the dynamic light source, be applied to the detection of the dynamic range of the camera, and improve the detection efficiency and accuracy.
