摘要：

There is growing demand for ensuring accuracy with respect to the assembly of new aircraft. The commonly used digital-measurement auxiliary assembly system cannot meet this demand. In this study, a new multidevice hybrid docking measurement method is proposed based on the iGPS laser measurement system. Further, a position measurement model, position solution model, and docking path solution model are established based on the aforementioned method. After guiding the global docking, the iGPS laser measurement system triggers the local multidata fusion measurement system to detect the local position. The local position solution model can be used to obtain the angle error and position error between the joint ear pieces. The docking path can be optimized after considering the compensation error, improving the docking accuracy. The experimental results indicate that the position accuracy after considering the compensation error is 5.8×10-2 mm and that the angle accuracy is 9°×103, indicating that the proposed method meets the actual docking accuracy requirements. © 2020, Chinese Lasers Press.
