The calibration method for obtaining a transformation of coordinate systems between a vision sensor and a depth sensor includes the following steps. (a) A first coordinate group of four endpoints of a calibration board in a world coordinate system is created. (b) An image of the calibration board is obtained by the vision sensor, and a second coordinate group of the four endpoints of the calibration board in a two-dimensional coordinate system is created. (c) A third coordinate group of the four endpoints of the calibration board in a three-dimensional coordinate system is created according to the first and second coordinate groups. (d) The third coordinate group is transformed to a fourth coordinate group corresponding to the depth sensor to obtain the transformation of the coordinate systems according to at least three target scanning spots."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Calibration system for calibrating visual coordinate system and depth coordinate system, calibration method and calibration device","description":"The disclosure provides a calibration system, a calibration method, and a calibration device.
