文摘

In monocular vision system, non-coplanar target is extensively used for pose measurement. However, it remains a subject to be settled how to design and select the target parameters. This article proposes an optimized design method for non-coplanar target parameters to ensure that the monocular vision measuring system can attain optimal pose measurement accuracy. Firstly, a monocular-vision pose measurement model is established covering non-coplanar target parameters, and a pose measurement error model is deduced. On this basis, an objective function is put forward for optimizing the design of non-coplanar target parameters. Finally, simulations are conducted and the results verify the correctness of pose measurement error model and the effectiveness of the optimized design of target parameters.
