The Contactless Measurement for Big Cargo Extraction of Trajectory and Attitude Parameters Based on Multi-station and Differ-reference

In view of the narrow long room, fast speed and roll sport while outside the room, single camera couldn’t achieve the measurement of big cargo extraction. This paper puts forward an intersection measurement system of multiple ultra short focus cameras and high-speed cameras. The system can achieve the parameters of wholly sport process by measuring the marked points on cargo, coordinate conversion and data registration. Measurement data show the trajectory and attitude parameters truly. Measurement precision satisfies the requirement of subject.
