Abstract
Methods and systems for calibrating sensors of an autonomous vehicle are disclosed. The method includes using a target that includes a plurality of uniquely identifiable fiducials positioned on a panel to form a pattern, and at least one tag. Each tag corresponds to and is positioned relative one of the plurality of uniquely identifiable fiducials and includes information for determining a location of its corresponding uniquely identifiable fiducial with respect to the panel.
Claims20
A target for sensor calibration, the target comprising:
- a plurality of uniquely identifiable fiducials positioned on a panel to form a pattern;
- and
- at least one tag, each of which corresponds to and is positioned relative one of the plurality of uniquely identifiable fiducials, each tag comprising information for determining a location of its corresponding uniquely identifiable fiducial with respect to the panel.
A method for sensor calibration, the method comprising:
- recording a plurality calibration images of a target using a camera, wherein the target comprises:
- a plurality of uniquely identifiable fiducials positioned on a panel to form a pattern, and
- at least one tag, each of which corresponds to and is positioned relative one of the plurality of uniquely identifiable fiducials, each tag comprising information for determining a location of its corresponding uniquely identifiable fiducial with respect to the panel;
- determining, based on information retrieved from the at least one tag and captured images of the plurality of uniquely identifiable fiducials, locations and identifications of one or more fiducial markers in the calibration images;
- and
- based on the determined locations and identifications, validating whether the camera is calibrated.
A system for sensor calibration, the system comprising:
- a processor;
- and
- a non-transitory computer-readable medium comprising programing instructions that when executed by the processor will cause the processor to:
- record a plurality calibration images of a target using a camera, wherein the target comprises:
- a plurality of uniquely identifiable fiducials positioned on a panel to form a pattern, and
- at least one tag, each of which corresponds to and is positioned relative one of the plurality of uniquely identifiable fiducials, each tag comprising information for determining a location of its corresponding uniquely identifiable fiducial with respect to the panel,
- determine, based on information retrieved from the at least one tag and captured images of the plurality of uniquely identifiable fiducials, locations and identifications of one or more fiducial markers in the calibration images, and
- based on the determined locations and identifications, validate whether the camera is calibrated.
