LOCATION MEASUREMENT ERROR DETECTION

A system determines an accuracy of a set containing a plurality of sensor location measurements of a client device and generating a set of sensor location measurements labeled with an associated accuracy estimate, is presented. The system receives a plurality of sensor location measurements of the client device generated by a location sensor. The system may determine the accuracy of a sensor location measurement by comparing the sensor location measurement to a reference location measurement, such as VIO location measurements computed using VIO data. The system computes a first set of location translations for the set of sensor location measurements and a second set of location translations for the set of VIO location measurements. The system may calculate a measurement difference between each corresponding pair of location translations from the first and second set, identify measurement differences that exceed a threshold, and label the corresponding sensor location measurement as inaccurate.
