Abstract
Disclosed are a calibration device, a calibration system and a calibration method. The calibration device includes a camera configured to capture image information, a laser sensor configured to capture image information, a laser sensor configured to detect distance information, and a calibration module configured to perform a calibration of the camera and the laser sensor by obtaining a relation between the image information and the distance information, wherein the calibration module includes a plane member disposed to intersect a scanning surface of the laser sensor such that an intersection line is generated, and disposed within a capturing range by the camera so as to be captured by the camera, and a controller configured to perform coordinate conversions with respect to the image information and the distance information based on a ratio between one side of the plane member and the intersection line, and based on a plane member image included in the image information. Under these configurations, a calibration is performed through direct coordinate conversions with respect to image information and distance information.
