Abstract: We present a high-definition (HD) 3D laparoscopic system including a dual channel optical system, two cameras, a camera control unit (CCU), and an HD 3D monitor. This laparoscopic system is capable of outputting dual high-definition videos and providing vivid 3D images. A modified pinhole camera model is used for camera calibration and a new method of depth measurement to improve precision. The average error of depth measurement measured by experiment (about 1.13 mm) was small in proportion to the large range in distance of the system (10–150 mm). The new method is applicable to any calibrated binocular vision system.
The authors constituted a set of 3D laparoscopic system using two HD cameras, and calibrated the camera system using a novel algorithm in consideration of a different focal length and rotation angle between two cameras as well as relatively short working distance in real laparoscopic surgery. It is interesting.
