Abstract
A method of performing an absolute length calibration for an object located with or covered by a camera device in a mirror. The dimensions of the camera device are determined and an image is captured by the camera device of the camera device with the object. A length of the image of the object and the dimensions of the image of the camera device are measured and those measurements are used to calibrate the image.
Claims12
A method of calibrating a camera device for processing an image captured in a mirror, the method comprising:
- capturing, by the camera device, the image depicting the camera device and an object in a mirror;
- determining a field of view of the camera device for the image;
- determining a camera device offset length, the camera device offset length including an image length from a center of the image to a location of the depicted camera device in the image;
- and
- deriving an absolute angular calibration angle between the camera device and the mirror based at least in part on the camera device offset length, a total image length of the image, and the determined field of view.
A camera device configured to execute software that, when executed by the camera device, causes the camera device to:
- capture an image depicting the camera device and an object in a mirror;
- determine a field of view of the camera device for the image;
- determine a camera device offset length, the camera device offset length including an image length from a center of the image to a location of the depicted camera device in the image;
- and
- derive an absolute angular calibration angle between the camera device and the mirror based at least in part on the camera device offset length, a total image length of the image, and the determined field of view.
