Claim 0:
1. A computer-implemented method comprising:
receiving camera frame and sensor data from a client device associated with a location-based application;
inputting the received data into a computer vision algorithm to generate candidate pose estimates, each pose estimate representing a prediction of a three-dimensional position and orientation of the client device and having an associated confidence score;
for each candidate pose estimate:
mapping the candidate pose estimate to a position in a prior model of a geographic area in which the client device is located;
determining, using the prior model, a probability that the client device is located at the three-dimensional position; and
fusing the confidence score with the probability to generate an updated confidence score;

selecting an authoritative candidate pose estimate from the pose estimates using the updated confidence scores; and
causing the client device to provide location-based content within the location-based application using the authoritative pose estimate.
