Abstract for “Mobile sensor calibration”
“One embodiment of a method involves receiving sensor data from one (or more) sensors of an autonomous car (AV); and determining whether a sensor of the one(s) sensors requires recalibration based upon the sensor data. The first sensor is of the first sensor type. This method includes sending a request through a remote management system to indicate that one or more sensors of an AV require calibration and the location of the vehicle; determining whether a service vehicle has a calibration target to calibrate the first sensor type; and initiating the calibration routine with the calibration target.
Background for “Mobile sensor calibration”
A safe and successful navigation system for an AV requires accurate measurement and representation of its external environment. A three-dimensional model or data of the external environment that is accurate and reliable depends on the accuracy of the AV sensors. This may include understanding the initial configurations of the sensors as well as how obstacles and objects are detected by them. The sensors of an AV might need periodic calibration to maintain an accurate representation of the environment. This is necessary for safe navigation. Recalibration can be time-consuming due to the many sensors an AV might be equipped with. While the sensors are being calibrated, AVs can be inoperable or taken offline. This reduces the use of the AVs as well as the capabilities of an AV management software. Calibration of sensors can be a tedious, manual process, which may require specialized labor, and increase costs for operation.
