Claim 10:
11. An error handling method for a sensor of a system, performed by one or more processors, the error handling method comprising:
determining a probability of whether the sensor is uncalibrated based on one or more sensor parameters or a comparison of a proportion of features from data captured by the sensor and historical data at a same location, wherein the sensor parameters comprising any of a skew, a depth of field, an angle of view, a beam angle, an aspect ratio, and a pixel number;
in response to determining that the probability of whether the sensor is uncalibrated satisfying a threshold probability, selecting a first error handling mechanism based on a previous rate of success of recalibration relative to a specific location, a specific landmark, or a type of landmark, wherein the selecting of the first error handling mechanism comprises:
selecting a recalibration mechanism in response to the previous rate of success satisfying a threshold; and
selecting a different error handling mechanism in response to the previous rate of success failing to satisfy the threshold;

performing the first error handling mechanism in accordance with the selection of the error handling mechanism;
determining whether the sensor is validated following the first error handling mechanism;
in response to determining that the sensor is not validated following the first error handling mechanism, performing a second error handling mechanism and a second validation;
upon determining that the sensor is validated after the first error handling mechanism or the second error handling mechanism, capturing sensor data using the sensor after the first error handling mechanism or the second error handling mechanism; and
navigating a vehicle using the sensor data.
