Multi-sensor real-time alignment and calibration

Abstract:

Methods and systems for multi-sensor real-time alignment and calibration are disclosed herein. A vehicle includes a projector configured to project a pattern on a target location. The vehicle also includes one or more sensors. The one or more sensors are configured to capture sensor data from the target location and detect the pattern at the target location. The vehicle further includes a calibration system configured to determine whether a particular sensor of the one or more sensors is out of alignment based on a relative position of the pattern as detected by the one or more sensors. The calibration system is also configured to, based on a determination that the particular sensor is out of alignment, adjust an alignment of the particular sensor based on the sensor data and the diffractive pattern.
