【摘要】:提出一種基于微機(jī)電慣性測量單元的室內(nèi)定位系統(tǒng)。在本系統(tǒng)中,行人在一個平面上的位置和方向通過計算對人體膝部和腰部佩戴的傳感器數(shù)據(jù)來獲取。提出的算法實(shí)現(xiàn)了對膝部佩戴陀螺儀的行人行進(jìn)的步伐進(jìn)行復(fù)位計算以消除角位移誤差,同時實(shí)現(xiàn)了對腰部佩戴陀螺儀測量的角速率進(jìn)行連續(xù)推算以獲取行進(jìn)方向。結(jié)果表明,在一個平面上,行進(jìn)62.32m的總距離時平均誤差僅為0.1935m,標(biāo)準(zhǔn)差為0.0512m。
[Abstract]:An indoor positioning system based on micro-electromechanical inertial measurement unit is proposed. In this system, the position and direction of pedestrians on a plane are obtained by calculating the sensor data worn on the knee and waist of the human body. The proposed algorithm realizes the reset calculation of the walking pace of pedestrians wearing gyroscope on the knee in order to eliminate the angular displacement error, and realizes the continuous calculation of the angular rate measured by the waist wearing gyroscope in order to obtain the moving direction. The results show that the average error is only 0.1935 m and the standard deviation is 0.0512 m at the total distance of 62.32 m on a plane.
