This paper describes a method for estimating sensor biases by using a low-dimensional Unscented Kalman Filter (UKF) to maintain the positional estimation accuracy of an autonomous vehicle (AV). It is difficult to estimate attitude accurately in a blind situation (such as with no GPS satellites and no landmarks), because of sensor bias. We developed a dead(More)
This papcr presents a 3D-environment nieasurcmcnt systeni for large-scale structure manufacturing. First, a niethod and systeni for generating as-built data are shown. Then a camera calibration method that provides the ncces\ary nieasurenicnt precision in space is introduced, and the nieasurement error is analyzed quantitatively. Finally, the position and(More)
