A target detection method to mitigate interference of non-uniform illumination

Non-uniform illumination makes it's difficult to detect and extract the target. To locate multiple target under complicate illumination, an improved vision system was designed in this paper. After analyzed kinds of image-binaryzation strategy, we choose the adaptive threshold binarization as the image binarization strategy. Through image processing, morphological processing, adaptive threshold binarization and contour detecting algorithm, a vision system have been designed out on the platform of Virtual Studio 2013. Experiment shows that vision system can locate multiple target efficiently under non-uniform illumination.
