Capsule endoscope is a small, ingestible device that resembles a regular drug capsule in appearance, measuring approximately 2-3 centimeters in length and 1 centimeter in width. It is equipped with miniature cameras, light sources, sensors, wireless transmission modules and other components inside. After the patient swallows the capsule, it moves freely in the gastrointestinal tract. The camera captures images of the inner wall of the intestine and transmits them wirelessly to an external receiver. The doctor can receive and analyze the images through the receiver. Usually with high image resolution, it can observe lesions in the intestine in detail, especially in areas that are difficult to examine through conventional endoscopy, such as the upper part of the small intestine. The entire examination process does not require anesthesia, and patients do not need to make any special preparations. They only need to continue their daily activities after swallowing the capsules.

Advantages of Capsule Endoscopic Measurement:
1. Non invasive: Capsule endoscopes do not require insertion of a catheter into the body, so they will not cause any trauma or discomfort. Patients can engage in daily activities at home, greatly improving the comfort and convenience of the examination.
2. Not dependent on operating techniques: Traditional endoscopes require manual operation by doctors and are easily influenced by their experience and skills. The images of capsule endoscopes are automatically captured and transmitted, avoiding human interference during the operation process and having higher objectivity.
3. Pain free: Traditional endoscopy often requires anesthesia or analgesic drugs, while capsule endoscopy is completely painless, and patients do not need to worry about postoperative discomfort.
4. Wide applicability: Capsule endoscopes are particularly suitable for examining the small intestine, which is usually not fully observable under traditional endoscopes. The flexibility of capsule endoscopy enables it to reach various parts of the intestine, providing comprehensive examination results.
Capsule endoscope measurement and data analysis:
1. Image measurement: Through the built-in camera, the capsule endoscope can capture high-definition images of the gastrointestinal tract. These images can be used for post analysis to help doctors measure intestinal lesions, polyps, ulcers, etc. By measuring the dimensions on the image, doctors can determine the size, shape, and possible pathological features of the lesion.
2. Temperature and pressure measurement: Some advanced capsule endoscopes are also equipped with temperature sensors and pressure sensors. Temperature measurement can help determine the degree of inflammation in the intestine, while pressure sensors can provide relevant information on intestinal peristalsis to assist doctors in analyzing the status of intestinal function.
3. Intestinal motility measurement: Intestinal peristalsis is crucial for the digestive process. Modern capsule endoscopes can monitor intestinal movements in real-time through built-in sensors, providing detailed data on intestinal movements. This is of great significance for the diagnosis of some intestinal dysfunction.
4. Image processing and analysis: In order to improve diagnostic accuracy, images of capsule endoscopes are often analyzed using computer image processing technology. For example, through technologies such as edge detection, lesion area annotation, and automatic classification algorithms, key information can be extracted from a large amount of image data to assist doctors in making accurate diagnoses.
