Wireless Energy Transmission System for Capsule Endoscopy Based on Image Processing Technology

Abstract

The current capsule endoscopy power supply generally uses a battery, which has security risks and will affect the efficiency of capsule endoscopy to a large extent. Therefore, this paper constructs a wireless energy transmission system for capsule endoscopy based on high power and low loss transmission of image processing technology. By improving the merging mode of image processing, image processing is combined with wireless transmission to achieve efficient image processing in wireless transmission. Given the two-dimensional structure of the image, this paper also configures the block in the kernel as a two-dimensional structure. To obtain the best energy transfer performance, this paper tests all the possible combinations of the two dimensions. Then point-to-point high-frequency mode is used for inductive transmission of energy. Research shows that the wireless energy transmission system based on image processing technology can transmit energy in the frequency of 50 Hz-60 Hz, the loss rate is between 11% - 19%, and the overall efficiency has small fluctuations in different modes. Compared with wired power transmission, this system has only a small loss increase, but its efficiency is more than 30% higher than that of battery. And after 100 groups of image testing, this system takes a short time and can meet the wireless power transmission effect of capsule endoscopy.
