摘要： A method comprises displaying a first image acquired from a camera having an input camera projection model including a first focal length and an optical axis parameter value. A portion of the first image is selected as a second image associated with an output camera projection model in which either a focal length and/or an optical axis parameter value differ from the parameters of the input camera projection model. The method involves iteratively: adjusting either the focal length and/or an optical axis parameter value for the camera lens so that it approaches the corresponding value of the output camera projection model; acquiring a subsequent image using the adjusted focal length or optical axis parameter value; mapping pixel coordinates in the second image, through a normalized 3D coordinate system to respective locations in the subsequent image to determine respective values for the pixel coordinates; and displaying the second image.

摘要： According to one embodiment of the disclosure, an implant includes a body having a surface with a flexible pattern defined by a plurality of material segments including a first material segment and a second material segment. The first material segment abuts the second material segment. Further, the first material segment includes a first non-linear shape extending between a first end and a second end while the second material segment includes a second non-linear shape extending between a first end and a second end. The two material segments are interconnected such that one of the first end and the second end of the first non-linear shape is interconnected with one of the first end and the second end of the second non-linear shape.
