基于ov7930芯片磁控人体胶囊式无线内窥镜的研究与实验

Research and Experiment of a Capsule Wireless Endoscope for Human Usage Based on the OV7930 Chip

选用ov7930芯片对内窥镜进行设计,通过理论分析和实践研究,对所涉及到的光学、图像、发射、控制和电源等关键技术进行了详细的分析和设计。根据实验室的条件,研制出基于ov7930芯片、磁定位、计算机影像采集的样机,并进行了动物离体和活体实验。

In this paper,an OV7930 chip is selected to design an endoscope.With theoretical analysis and the practice research,the design has been carried out in optics of pictures,the launch and the control circuits,the power source and etc.Under the laboratory conditions and with the magnetic location,the computer image gathering prototype has been developed based on the OV7930 chip.Finally,a living animal experiment with a piggy has been carried out and some living photos inside piggy's body are obtained.
