In this paper, a method of measuring roll angle with hollow cube corner reflector(HCCR) is proposed. Firstly, the space coordinate vector relationship between the mirror and the autocollimator is established by using the Euler rotation relationship, and the structure of the HCCR is designed. Secondly, through the actual measurement of the HCCR reflector’s angle sensitivity, the specific formula of roll angle measurement is obtained. The experimental results show that the method can be used to measure the roll angle, and the maximum root mean square(RMS) error is 15" in the range of 350", and the repeatability of the experiment is better than 2.7". On the basis of retaining the traditional autocollimator, the plane mirror is replaced with HCCR, which realizes the measurement of the roll angle of the autocollimator. This method does not change the internal structure of the autocollimator system, and there is no process error caused by special processing technology, so as to retain the autocollimator’s own long measurement distance, high measurement accuracy, high system stability, and large range of measurement performance, and it can also be used in industrial production.

为了利用便携式设备准确监测老年人的跌倒状况,提出了一种基于softmax回归的多种行为模式分类识别方法,设计并实现了基于智能手机终端的远程人体姿态监测系统。首先,构建softmax分类器分析8种日常行为模式下的加速度模值特征,由于跑步时加速度模值与突然跌倒时类似,引入倾斜角特征进行二次判别,从而识别出突然跌倒行为;针对缓慢跌倒行为下加速度模值特征不明显的问题,在softmax分类器中引入躺倒时间特征,通过设置躺倒时间阈值并判断原始位置是否在时间阈值内恢复,从而识别出缓慢跌倒行为。实验与测试结果表明,该系统准确度为95.40%,特异度为95.33%,灵敏度为95.50%,具有较高的跌倒行为识别精度,对老年人的健康状态监测提供了一种可行方案。
