Abstract
A sensor calibration system (5) for watercraft (1), comprising: a primary environment sensor (7A, 8A) configured to detect an external object including a first or second region of the watercraft and a distance to the external object, and mounted to a part of the watercraft; and a processor (11) for processing an output of the primary environment sensor, wherein the processor is configured to identify a bow (1a) of the watercraft from the output of the primary environment sensor, and calibrate a position and an orientation of the primary environment sensor relative to the bow.
Claims11
A sensor calibration system for a watercraft, comprising:
- a primary environment sensor configured to detect an external object including a first region of the watercraft and a distance to the external object, and mounted to a part higher than a deck of a hull of the watercraft;
- and
- a processor for processing an output of the primary environment sensor, wherein the processor is configured to;
- accept hull information including a length, a width, and a height of the watercraft;
- identify a bow of the watercraft from only a predetermined height range from the primary environment sensor, within which an outer edge of the hull of the watercraft is expected to be located, from the output of the primary environment sensor based on the height of the watercraft;
- and
- determine and calibrate installation position information of the primary environment sensor, the installation position information including a longitudinal distance from the bow to the primary environment sensor, a lateral distance from a longitudinal center line of the hull of the watercraft to the primary environment sensor, and a lateral angle of the primary environment sensor, based on the hull information and the output of the primary environment sensor.
