Abstract :
As one of the important health indicators of the body, plantar pressure distribution has great reference value in clinical medicine, sports and fitness training, and rehabilitation fields. The purpose of plantar pressure collection is to identify the movement patterns and pressure distribution information of the human lower limbs. This article focuses on introducing the design of plantar pressure detection and motion detection systems from the aspects of array plantar pressure sensors, STM32 acquisition circuits, acquisition programs, and gait segmentation recognition algorithms. During the process of human body state recognition, the collection system sequentially scans 16 plantar pressure sensors and transmits the collected data to the pressure measurement recognition software for real-time graphic display and motion recognition. Wireless communication is carried out using WiFi transmission, and repetitive action segmentation and different pose recognition are achieved using gait segmentation algorithm and SVM algorithm. And a detection system experimental platform was built to recognize 8 daily movements such as sitting, standing, and going up and down stairs, with a recognition rate of 93.65%, laying the experimental foundation for motion parameter analysis and foot rehabilitation evaluation. © 2023 IEEE.

Abstract :
In order to select and recommend the optimal parking lot for the users, a novel intelligent selection algorithm based on the grey relational analysis considering user preferences is proposed. The parking-lot evaluation index system consisting of indicators in effectiveness, convenience, economy, environmental attribute and agreeableness is firstly established. The comprehensive weight determination method combining the expert estimation method with the user preference settings is proposed to determine the comprehensive weight of each evaluation index, and this method can meet the personalized needs of individual user to the greatest extent. The evaluation indexes considering various representative objective and subjective influential factors including the driving distance between the current location and the target parking lot, the walking distance between the target parking lot and the destination, the remaining parking spaces, the parking fee, the condition of the hardware facilities and service quality are determined, and the corresponding comprehensive weight of each evaluation index is calculated. Then the parking lots near the destination are evaluated by the grey relational analysis in order to select the optimal one to the user for parking reservation. This algorithm has been proven to be effective by the APP on Android mobile phones. © The Author(s) 2021.

Abstract :
本发明涉及一种基于AABB与OBB自适应的复合包围盒算法。首先,设定方向轴夹角阈值eps;其次,由顶点坐标和索引数据计算包围盒的中心位置m;计算协方差矩阵C;求协方差矩阵C的特征向量并单位化,作为零件的三个方向轴;分别计算零件三个方向轴与标准坐标轴XYZ的夹角θ1、θ2、θ3;最后,将θ1、θ2、θ3分别与给定阈值eps进行比较,若都小于等于给定阈值eps,则采用AABB包围盒,计算AABB包围盒的长、宽、高,根据中心m构建AABB包围盒;若其中有一个夹角大于给定阈值eps,则根据中心位置m、绕标准坐标轴的旋转角度、、构建OBB包围盒。本发明能够根据三维零件模型的实际特征,自适应地选择采用AABB方法或OBB方法构造零件包围盒,灵活性好,具有一定的智能化水平。
