利用三维重建进行粒子统计的方法

针对单张二维图片难以准确完成粘连粒子计数与体积计算的问题,提出了一种基于重建的空间统计算法。首先对CT切片图像采用数学形态中的腐蚀处理,得到粘连粒子分离图像,然后采用Marching Cubes算法对切片图像进行三维重建,再将重建的粒子以STL数据格式保存,最后根据STL数据的特征和粒子的连通性完成统计。实验结果表明,当球形粒子随机噪声分布概率在20%以内时该方法能够准确完成粘连粒子计数和粒子体积

基于模糊识别的驾驶员疲劳检测

汽车驾驶员疲劳驾驶是导致交通事故的重要原因之一,通过监测驾驶员的眼睛可以判别驾驶员的疲劳程度。对驾驶员眼睛的张开程度、眨眼频率、闭眼持续时间占空比等状态量进行检测和运算分析,提出利用模糊识别算法判别驾驶员眼睛疲劳状态。实验结果表明,该方法能有效识别驾驶员的疲劳状态,实时性好,准确率高。
