A Multi-camera Wireless Capsule Endoscopic System

The aim of this project is to build an efficient multi camera wireless capsule endoscopic system, thereby trying to make the capsule have 360° angle of view. The primary idea is to address the problem of limited diagnosis caused due to the formation of blind areas while using a single camera. A multi camera approach helps to reduce the blind area. However increased image sensors cause increase in power consumption. In this work, a 4 camera wireless capsule system prototype was built which uses JPEG image compression to reduce the data size needed to be transmitted by the RF transmitter. Stellar is LM4F120 (ARM Cortex M4) micro controller performs the main task of image compression, EZ430-RF2500 to establish the wireless link and the cameras used are Omni vision´s OV7760.
