Device and method for calculating coordinate of track and coordinate of detected point
The invention discloses a device and a method for calculating the coordinate of a track and the coordinate of a detected point. The method is characterized in that a high-precision CPIV track datum net point is utilized as the measuring basis of a three-dimensional detection system of the track; a benchmark total station and an auxiliary total station directly capture a CPIV datum net prism in order to obtain coordinate values of the CPIV datum net prism on two total stations; by calculating position difference between the benchmark total station and the auxiliary total station, influence of connection error for left and right car frames upon positions of total stations is eliminated; and the coordinate of the detected point of the track and the coordinate of a center line of the track are calculated under the principle of euler angles and the law of rigid body motion. A track detection trolley comprises a right trolley frame, the auxiliary total station, the benchmark total station, a left trolley frame and a dual tilt sensor. The method for the coordinate of the detected point and the track detection trolley have following beneficial effects: a digital model of a detection system is simplified via principles of euler angles and the law of rigid body motion; the coordinate of the detected point of the track and the coordinate of the center line of the track can be rapidly calculated; and detection precision and efficiency are enhanced.
