Abstract The stereo vision ability of human beings enables the surgeon with depth perception, and thus can allow for organ localization in human body. In this work, we propose an approach of developing a 3D prototype for stereo endoscopes. The stereo calibration and rectification processes have been implemented in order to nullify the effects of lens distortions. The processed output was in interlaced format and can be visualized in 3D format on a passively polarized monitor using polarized glasses. The proposed system also provides the snapshot, video write, and retrieval in individual left and right streams along with live process display. The scaling feature provides a detailed view of the selected region of interest.

1 Introduction The modern advancements in the display devices have modified the facilities in the form of tools in a dynamic and remarkable way for surgical applications. Earlier known techniques such as MRI allows for an approximation view of the patient organs without providing their localization information to the surgeon along with their radiation hazards. The surgeon has to perform the surgery using long incisions and it leads to long recovery times of patients and risks of infection also. To solve this problem, the 2D endoscopes had been used which helps in performing surgery using small incisions but it lacked depth information and also suffers from image Dhiraj (✉) ⋅ P. Soni ⋅ J.L.

distortion effects [1]. The lack of depth perception in the observed scene earlier made the endoscopy less effective. The human anatomy requires depth perception by the surgeon in order to make the surgery more effective and result-oriented. Many researchers had used different techniques for retrieving depth information from the images. In robot assisted surgery, ultrasound images had been used for 3D reconstruction [2]. The computer-aided surgery (CAS) software had also been used for decreasing errors of clinical after effects. The depth information was simulated by using imaging algorithms by regenerating the stereo data from two separate video streams. In this article, a prototype of a real-time FULL HD stereo system using Misumi sensors is shown in Fig. 1 has been demonstrated. The Misumi MD-B5014-3.0 and Misumi MD-B5014LV-3828 have been used for making the stereo rig for the endoscope. The camera are very small in size with a foot print of 14 × 26 mm only as shown in Fig. 1. In earlier attempts, the 3D was visualized using activ
