Abstract :
This paper presents an illumination compensation method for images under variable lighting condition. The algorithm consists of two processes. First, the camera response function is identified as a nonlinear model of the camera under dynamic illumination. Then an image with a wider dynamic range is obtained online by fusing several images taken under different exposures of the same scene. The algorithm is applied to the four-legged robot soccer competition and is verified to be superior to some traditional schemes.
