Angle Data Compensated Ranging Using MultipleSensors Data Fusion of Smart Phone
摘要
Abstract
In the field of inertial measurement,it does not accurately perceive the target object movement distance by simply using double integration of acceleration method.Acceleration sensor in the sense of linear movement of the target object is more accurate and practical,but it will change the direction of the drift continually occur in the three-dimensional movement of its axis with the object.To solve this problem,this paper proposes an algorithm that angle data compensated ranging (ADC-R)using multiple sensors data fusion of smart phone:acceleration sensor is used to measure the movement of object acceleration as calculated displacement of the original data;it is using gyroscope sensor to measure angular velocity of the moving object and the output data of the rotation vector sensor is used as the parameter to convert the measured acceleration value space coordinate of mobile phone to the static reference coordinate system.According to the relationship between acceleration and displacement of physics,the method of mathematical integration and the technique of further error correction are used to get the final moving distance.The experimental results show that this method has high precision in the near distance ranging and it is better than the acceleration integral ranging algorithm and acceleration gyroscope fusion ranging algorithm.关键词
