Method of tracing position of pipeline using mapping probe
A method of tracing a position of a pipeline using a mapping probe includes: inserting and moving the mapping probe in a pipeline; receiving and keeping acceleration information and angular information in real time in a memory; estimating Euler angle (roll and pitch); estimating Euler angle (roll, pitch, and yaw); estimating a system modeling; estimating and applying covariance of system noise and covariance of measured noise; estimating three-dimensional position information modeling; receiving and keeping movement distance information of the mapping probe from an encoder in a memory; estimating and keeping in real time three-dimensional position information of the mapping probe in the memory; receiving the accumulated real-time three-dimensional position information of the mapping probe; mapping the accumulated real-time three-dimensional position information of the mapping probe to geographic information; and displaying the accumulated position information of the mapping probe mapped to the geographic information on a display unit.
