Abstract
A client device estimates an error in a heading component of a magnetometer measurement based on an error in a vertical component of the magnetometer measurement. The client device receives a three-dimensional measurement from a magnetometer including a heading and a vertical component. The client device identifies an expected vertical component based on a position of the client device and a magnetic map. The client device generates an error estimate based on the vertical component of the three-dimensional measurement and the expected vertical component. The client device compares the error to an error threshold and, in response to the error estimate being less than an error threshold, determines a pose of the client device based on the heading. The client device displays augmented reality content to the user using the pose.
