Abstract

Minimally Invasive Surgery (MIS) is a current major surgery technique. A chief problem with MIS is its narrow field of vision. A wireless MIS Panoramic Endoscope (WMISPE) is developed and implemented to provide doctors with broad fields of view. A WMISPE features a combination of video overlapping and video stitching. The panoramic video apparatus has two side-by-side endoscopic lenses that provide wide-angle inputs for video stitching. A WMISPE can provide doctors with panoramic videos, so that they can easily discriminate an organ's position between surgical operations. Experimental results show that WMISPE can enhance the video size to 158%. A low-power multi-mode video decoder (MMVD) is used to validate the stitching videos. The whole system is validated by personal computer, an embedded system, and an H.264 decoder chip. The test chip is successfully validated after system integration, and obtains about a 24% reduction in power consumption, which is better than that of the same design using a single supply voltage. The animal vivo experimental videos have been successfully validated.
