摘要: 目前军事、医疗、科技、电影、游戏等很多应用领域都需要对移动主体的运行轨迹进行捕捉。现有的移动主体轨迹识别与绘制机制一般对设备的要求较高,且算法复杂,实时性不够理想。为此,提出一种基于多传感器数据融合的移动主体运行轨迹捕捉机制,以智能移动终端为载体,联合采用加速度传感器和姿态传感器采集数据,通过对加速度传感器和姿态传感器采集的数据进行处理和融合,并应用物理学中加速度和位移以及数学中曲线和直线的关系,准确识别移动主体的行动轨迹;然后利用光学透视投影的原理将轨迹投影到二维空间,并在智能终端的屏幕上绘制出来。实测结果表明,该机制具有较高的准确性和实时性,且具有理想的时空复杂度。

关键词: 加速度传感器,姿态传感器,数据融合,运行轨迹捕捉

Abstract: At present,many fields,such as military,medical care,science and technology,movies,games and many other applications need to capture moving trajectories of moving objects.Existing mobile trajectory recognition and mapping methods generally have high requirements for equipment and have complex algorithms.What’s more,their real-time performance is not ideal.This paper presented a multi-sensor data fusion based mobile trajectories capture mechanism with the intelligent mobile terminal as the carrier,combined with the use of acceleration sensor and attitude sensor to collect data.Through the fusion of the data and the application of the relationship between acceleration and displacement and the relationship between curve and straight line,accurate identification of moving body movement can be acquired.After that,the mobile trajectory can be projected onto a two-dimensional space using the principle of optical perspective projection and mapped on the screen of the intelligent terminal.Experimental results show that the mechanism with high accuracy and real-time performance has the ideal time and space complexity.
