SENSOR MISALIGNMENT DETECTION AND ESTIMATION SYSTEM |
摘要 |
A misalignment detection sensor assembly is provided, which includes a forward-looking sensor having a sensing direction along a first axis and an inertia sensor configured to sense acceleration along a second axis, the second axis having a fixed relationship with respect to the first axis. A misalignment detection system uses the misalignment detection sensor assembly and a signal processing system to calculate a misalignment angle between the first axis and the direction of forward motion of the sensor assembly. A method of detecting angular misalignment of a forward-looking sensor assembly is also disclosed, which includes measuring acceleration along an axis having a fixed relationship with respect to the sensing axis of the forward-looking sensor assembly and comparing the acceleration measurement with a predetermined threshold. |
