摘要：为了精确提取鞋底激光光条中心,首先对原始的激光光条图像进行了高斯滤波处理,有效去除了图像噪声,然后采用自适应阈值算法提取了激光光条中心。该方法在利用极值法得到光条的近似中心之后,在光条近似中心小区域内采用重心法计算,实现了激光光条中心的提取。实验结果表明,该算法能够准确地提取出光条中心,具有很强的抗噪声能力。

Abstract: Aiming at extracting structured light stripe center position on soles accurately, the original image of light stripe was treated with gaussian filtering method and the image noise was effectually eliminated firstly.Then adaptive threshold method was adopted to extract structured light stripe center. In this research, quasi-center of structured light stripe was gotten via the extremum method at first, and then, centre-of-gravity method was adopted to calculate the center of structured light stripe near the quasi-center in a small regions around. Experimental results indicate that this algorithm can extract center of structured light stripe accurately, and it is of strong anti-noise capability.
Key words: soles information; structured light; light stripes center; center-of-gravity method
