Abstract
Navigation systems can identify objects in an environment and generate representations of those objects. A representation of an articulated vehicle can include two segments rotated relative to each other about a pivot, with a first segment corresponding to a first portion of the articulated vehicle and the second segment corresponding to a second portion of the articulated vehicle. The representation can be based on a model fit to points that are derived from sensor data and are associated with the object. In some examples, the model can be fit to the points using an expectation maximization algorithm and can be parameterized using attributes of the first and second segments.
