Abstract
Methods, systems, and devices for calibrating a camera device are described. The camera device may capture a first set of images of a physical environment and a second set of images of the physical environment having at least one illuminated reference point. The camera device may use a multi-dimensional target for calibration that may be formed by a quantity of illuminated reference points. That is, the illuminated reference points may be part of the multi-dimensional target. The camera device may determine a location of at least one illuminated reference point in an image of the second set based on an image of the first set and the image of the second set, and determine an association between the location of the at least one illuminated reference point in the image of the second set to a physical location of the illuminated reference point in the physical environment. As a result, the camera device may be calibrated.
