摘要： The present invention provides a method and a device for calibration applied to the field of image processing. The method includes: acquiring a common two-dimensional image and an infrared image of a calibration object, wherein the calibration object carries a first pattern; calculating coordinates of the first pattern in the common two-dimensional image, acquiring coordinates of the first pattern in a global coordinate system, and calculating intrinsic parameters of a first camera device capturing the common two-dimensional image; and calculating coordinates of the first pattern in the infrared image, acquiring the coordinates of the first pattern in the global coordinate system, and calculating intrinsic parameters of a second camera device capturing the infrared image. The method for calibration is capable of enhancing calibration efficiency by a simple calibration method when calibrating a depth camera device.
