High precision measurement of position and posture of kinetic objects with laser trackers |
| |
Abstract: | In order to realize real-time position and posture measurement of kinetic objects with high precision , based on measurement principle of geographic coordinates with laser trackers , the fore and aft parts of a kinetic object were aimed at with two laser trackers respectively .Both the laser trackers were triggered to collect data synchronously , and real-time spatial coordinates of the fore and aft parts of the kinetic object were obtained .The position and posture of the kinetic object in spatial geographic coordinate were measured .The spatial position and posture were calculated with a software developed by ourselves . After theoretical analysis and experimental verification , the results show that the stability and precision of the measurement system are pretty well and the proposed method can satisfy the high precision requirements for measurement of spatial position and posture. |
