  • Publication number: 20200100661
    Abstract: An integrated endoscope and visualization system comprises an endoscope, a visualization processing module and a 3D display device such as smart-glasses or naked-eye 3D display. The endoscope is equipped with two image capturing modules such as CMOS image sensors and can be disposable. The visualization processing module receives and encodes the images obtained by the two image capturing modules in order to generate an output visualization signal. The output visualization signal is transmitted to and displayed by the 3D display device in a 3D manner. The integrated endoscope and visualization system not only provides a 3D vision of surgical target during an endoscopic surgery operation, but also allow the medical personnel to walk or move during the surgery while keeping looking at the 3D images captured by the endoscope through wearable display devices.
