基于HSV颜色特征和轮廓面积的救生衣检测算法

摘要

目前国内外对渡口救生衣检测技术的研究还比较少,因此提出了复杂渡口环境下的一种能够识别救生衣的检测算法.统计救生衣的HSV颜色范围,用先验HSV颜色范围识别出待检测图像中的救生衣可能区域;通过边界跟踪得到图像中所有可能区域的轮廓,计算各个轮廓的面积来排除小面积区域的干扰;最终得到救生衣区域.实验表明,该方法能够比较准确地识别复杂环境下的渡口救生衣.%In light of few works about automatic life jacket detection at home and abroad, a novel life jacket detection algorithm is proposed to discriminate the life jacket in complex ferry environment. This paper counts the HSV range of life jacket image and identifies the likely region of life jackets from the pending image using prior color range;it calculates every contour's area to exclude the disturb by small area region after getting the contours of all likely regions in the image by border following algorithm. Finally it gets the life jacket area. Experiments show that this method can recognize the life jacket well in complex ferry environment.
