Multi-platform intelligent track comprehensive detection system

The invention provides a multi-platform intelligent track detection system. The multi-platform intelligent track detection system comprises an inertial measurement module (1), a GPS receiver (5), a speedometer, a laser range finder and an embedded computer. The track detection system is fixed on a running train or a driving trolley through a track detection beam, the inertial measurement module (1) is placed in the center of the detection beam, the orientation and the horizontal attitude angle of the detection beam are obtained through navigation calculation, and an inertial reference is established for optical measurement; the laser range finders are two-dimensional laser range finders (7), and the two-dimensional laser range finders (7) are arranged on the two sides of the detection beam respectively and used for measuring the distance between the inertial measurement module (1) and a track gauge point. The embedded computer carries out fusion calculation on the collected inertial navigation information, mi
