[0056] The color correction module 10 performs color correction on the image according to the RGB components separated by the color filter to ensure the accuracy and naturalness of color restoration;

[0057] The image compression and encoding module 11 compresses and encodes the processed image to reduce the amount of storage and transmission data.

[0059] Further, the receiving system includes a receiving micro control unit 12, a receiving power supply 13, a receiving module 14, a storage unit 15 and a 3D processing unit 16;

[0060] The receiving micro control unit 12 is used to control the receiving power supply 13, the receiving module 14, the storage unit 15 and the 3D processing unit 16 according to a preset program system;

[0061] The receiving power supply 13 is used to supply power to the receiving micro control unit 12, the receiving module 14, the storage unit 15 and the 3D processing unit 16;

[0062] The receiving module 14 is used to receive the data content transmitted by the transmitting module 5;

[0063] The storage unit 15 is used to store the data content received by the receiving module 14, so as to facilitate the extraction of corresponding data during subsequent diagnosis;

[0064] The 3D processing unit 16 copies the image data stored in the storage unit 15 through the receiving micro control unit 12 , performs panoramic imaging in the 3D processing unit 16 , and stores the panoramic image.

[0065] In this embodiment, the receiving power supply 13 provides power, and the receiving module 14 receives the signal data sent by the transmitting module 5. The received signal data is processed by the receiving micro control unit 12, and the image data is stored.

[0066] Further, the 3D processing unit 16 includes a 3D processing module 17 and a 3D data storage module 18;

[0067] The 3D processing module 17 is used to combine and process multiple single images to form a panoramic 3D image;

[0068] The 3D data storage module 18 is used to independently store the processed panoramic 3D image, and the panoramic image can be directly retrieved for use.

[0069] In this embodiment, the 3D processing module 17 performs 3D panoramic processing on the image data, and stores the processed results and data in the 3D data storage module 18, thereby ensuring the integrity of the 3D panoramic data through independent storage.

[0070] Furthermore, the virtual reality capsule endoscope also includes a distance measuring unit, which is used to measure the transmission distance between the endoscope micro control unit 3 and the receiving micro control unit 12 to ensure that the transmitting module 5 and the receiving module 14 can stably transmit image data.

[0071] In this embodiment, by measuring the distance between the endoscope microcontroller unit 3 and the receiving microcontroller unit 12, it is possible to avoid unstable image data transmission due to excessive distance, thereby causing partial image data leakage, and thus the patient is warned through the distance measuring unit.

When the distance calculation result between the transmitter 19 and the receiver 20 is higher than the preset range, the sound and light alarm 21 is activated to alarm. Conversely, when the distance calculation result is within the preset range, the distance measurement continues.

[0076] In this embodiment, the transmitter 19 continuously sends a radio wave signal to the receiver 20. After receiving the radio wave signal, the receiver 20 extracts and calculates the data of the radio wave signal, calculates the transmission distance according to the transmission time, and verifies the preset effective range according to the calculated transmission distance. When it is within the effective range, the transmission distance is continuously measured. When it exceeds the effective range, the sound and light alarm 21 is used to sound an alarm.

[0081] Furthermore, the virtual reality capsule endoscope also includes a power detection unit 24 , which is used to detect the remaining power of the receiving power supply 13 in real time and issue an alarm through the sound and light alarm 21 .

[0082] In this embodiment, the power detection unit 24 detects the remaining power of the receiving power supply 13, and issues an alarm according to a preset remaining power range. When the remaining power of the receiving power supply 13 is less, the sound and light alarm 21 issues an alarm to avoid interruption of image transmission due to power exhaustion.

[0085] The voltage sensor 26 is used to measure the voltage data of the receiving power supply 13;

[0086] The current sensor 28 is used to measure the current data of the receiving power source 13;

[0087] The temperature sensor 27 is used to measure the temperature data of the receiving power supply 13;

[0088] The analog-to-digital conversion module 29 converts the analog signals collected by the voltage sensor 26, the current sensor 28 and the temperature sensor 27 into digital signals for processing by the single chip microcomputer 25;

[0089] The constant current load module 30 is used to perform constant current discharge on the battery 1, which can reduce the influence of the virtual voltage of the battery 1 and improve the calculation accuracy of the remaining power.

[0090] In this embodiment, the voltage data of the receiving power supply 13 is measured by the voltage sensor 26, the current data of the receiving power supply 13 is measured by the current sensor 28, the temperature data of the receiving circuit is measured by the temperature sensor 27, and the analog signals of the voltage data, current data and temperature data are converted into digital signals by the analog-to-digital conversion module 29. The single-chip computer 25 reads the voltage data, current data and temperature data, and calculates the remaining power according to a preset program. At the same time, the constant current load module 30 further checks the remaining power.

[0091] When using a virtual reality capsule endoscope of the present invention, after a patient swallows the capsule endoscope, the capsule endoscope takes pictures of the digestive tract in the patient's body, and wirelessly transmits the taken image data to a receiver system 7. The receiver system 7 can perform 3D panoramic imaging processing on the taken image data while retaining the original image data. Planar image data and 3D panoramic data can be retrieved at will.
