Abstract:
Minimally invasive surgery (MIS) has the advantages of small trauma, quick recovery and lower risk of the surgery.Compared with the traditional two-dimension laparoscopic technique, three-dimension laparoscopic system uses the double beam imaging system as well as the three-dimensional imaging display device so as to compensate for the lack of depth information in two-dimension laparoscopic imaging technique, reduce the surgeon's difficulty in using surgical instruments and enhance the accuracy of the surgery. For those reasons, the author designed a glassesfree three dimensional wide-field electronic laparoscopic system, which consists of dual CMOS camera module,image processing module and glasses-free display module that can offer depth information. The active shape model is applied to eye tracking, for the purpose of getting the wide-field to help doctor obtain 3D display in more places.Primary experimental results of the simulation using the system show that operators with the aid of proposed system spend less time finishing the task than those using traditional system without depth perception during operation.
