Simulation of the single channel dual-spectrum low light level instrument

The single channel dual-spectrum low light level (LLL) instrument uses stripe light filter in the sole channel to obtain the stripe images which contain two LLL wave bands information. This paper specifies the simulation of the LLL stripe image, the method of separating and compensating the stripe image to the entire LLL short wave image and the LLL full wave image. The LLL stripe image is simulated by software from collecting information of dual-channel for the same scenery. The simulated LLL stripe image is separated and compensated by the method of inter-frame and in-frame, and the entire LLL images are rebuilt. The entire LLL short wave image and the LLL full wave image are fused to simulate the result of the single channel dual-spectrum low light level (LLL) instrument. The simulation experimental results indicate that the single channel dual-spectrum color low light level instrument has applied effectively, and has achieved the goal of the dual-band low light level image fusion and objects enhancement.
