Abstract
Provided herein is a system and method for determining whether a sensor is calibrated and recalibrating of an uncalibrated sensor. The system comprises a sensor system comprising a sensor and an analysis engine configured to determine whether the sensor is uncalibrated. The system further comprises an error handling system configured to determine whether to perform a recalibration in response to the sensor system determining that the sensor is uncalibrated. The error handling system further comprises a recalibration engine configured to perform a recalibration.
Claims20
A system comprising:
- a sensor within an autonomous or a semi-autonomous vehicle, the sensor comprising a Lidar, a radar, or a camera;
- and one or more processors configured to:
- perform a validation of the sensor to determine whether the sensor is calibrated;
- in response to performing the validation, and determining that the sensor is uncalibrated, determining a type or a mode of an error handling procedure, selected from error handling procedures based on a historical rate of success associated with the type or the mode of the error handling procedure, wherein the error handling procedures comprise initiating a backup sensor, recalibrating the sensor, eliminating erroneous data from the sensor, and issuing an alert;
- and
- perform the type or the mode of the error handling procedure.
An error handling method for a sensor of a system, comprising:
- perform a validation of a sensor to determine whether the sensor is calibrated;
- in response to performing the validation, and determining that the sensor is uncalibrated, determine a type or a mode of an error handling procedure, selected from error handling procedures based on a historical rate of success associated with the type or the mode of the error handling procedure, wherein the error handling procedures comprise initiating a backup sensor, recalibrating the sensor, eliminating erroneous data from the sensor, and issuing an alert;
- and
- perform the type or the mode of the error handling procedure.
