Embodiment Construction
[0049] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments It is a part of embodiments of the present invention, but not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.
[0050] In the prior art, images captured by a single-channel radio frequency RF transmission cavity mirror are prone to defects such as stuttering and flowering. The real-time performance of the image is poor, and the authenticity of frame loss processing is poor. In view of the above technical problems, this application uses independent dual cha...

The embodiment of the present invention provides a method and device for improving the reliability of wireless endoscope system image transmission. The embodiment of the present invention first acquires the image data of the predetermined area, and then uses the first communication channel and the second communication channel corresponding to the first predetermined frequency band respectively. The second communication channel corresponding to the predetermined frequency band transmits the above-mentioned image data obtained; after that, from the image data transmitted by the second communication channel, the corresponding data packet lost in the process of transmitting the above-mentioned image data by the first communication channel is obtained The data packets are obtained to obtain the target data packets; then, based on the image data transmitted by the first communication channel and the target data packets obtained from the second communication channel, the target image data is determined. The embodiment of the present invention overcomes the disadvantages in the prior art that in the image transmission process of endoscopic examination, it is easily interfered by the same frequency and adjacent frequency, and the real-time performance, smoothness and authenticity of the image display are poor.
Description
technical field [0001] The invention relates to the medical field, in particular to a method and a device for improving the reliability of image transmission of a wireless endoscope system. Background technique [0002] In the medical field, as a means of examination, laparoscopy is widely used in the examination of various diseases. In the process of laparoscopic examination, it is necessary to transmit the acquired picture of the detected position to the display terminal, so that the doctor can inspect and judge the lesion on the detected position through the image displayed on the display terminal. [0003] At present, the image acquired by the endoscope is transmitted to the display terminal that the doctor can observe. Generally, single-channel radio frequency RF transmission is used. However, during the process of single-channel RF image transmission, it is easy to suffer from co-channel interference and adjacent channel interference, so it is very easy to Faults such...
