Improved Design of Track 3D Inspection System Based on CPⅣ Network
Track geometry is extremely important for train operation safety.Based on CP Ⅲ track geometry static detection of the total station needs to be set up to track the traditional rail inspection trolley prism,operation is cumbersome and will produce a certain measurement error.Through the use of improved track inspection trolley installed total station to capture the CP Ⅳ reference point prism for track geometry static detection,and the use of Euler angles and general laws of motion of rigid body mathematical modelling of the system,the track can be faster calculated by the detected point as well as the median coordinates,to improve the measurement accuracy and efficiency.
