Abstract
Augmented reality applications require precise camera calibration to reduce the overall target registration errors. The camera calibration determines the mathematical model of the camera in order to determine how the physical world space is mapped to the camera image space and thus is highly dependent on the optics of the camera. The camera calibration algorithm normally assumes that the optics of the camera is rigidly fixed, which in fact is not at least for tilted laparoscopic cameras as illustrated in FIGS.to. Furthermore, any mechanical play between elements of the objective and the image converter will render the optics variable. According to the invention markers to will be placed within the field of view of the laparoscopic camera, which allows for determination of rotation of the optical part and mechanical misalignment without the necessity or providing any additional sensor.
