摘要 |
An improved position determination system that is resistant to interference caused by glint, such as from the Sun. The position determination system for determining positional parameters of an object has a target device comprising a base configured for attaching to the object, first and second target surfaces connected to the base; wherein the planes on which the first target surface and the second target surface are located are non-parallel to each other. The position determination system further comprises an image sensing device configured for forming a viewing path intersecting the target device and generating image information indicative of the geometric characteristics of the target device, and a data processing device configured to couple to the image sensing device for determining the orientation of the object based on the image information. If one of the target surfaces becomes obscured as a result of glint, the image of the other target surface alone is sufficient to determine object orientation. |
