Picture integrity checking method, communication device and capsule endoscope system

Abstract

The invention discloses a picture integrity checking method, a communication device and a capsule endoscope system. The picture integrity checking method includes the steps that S1, a sending terminaldivides pictures to be sent into a plurality of data packets, and all or part of each data packet is checked through a first algorithm, and all or part of obtained verification results are taken as afirst check value of the whole pictures to be placed at the position agreed with a receiving terminal in the pictures to be sent; and S2, the receiving terminal reorganizes the pictures based on thedata packets, checking is carried out according to the algorithm and sequence same as the sending terminal on the content of each data packet in the reorganized pictures and a second check value is obtained, the second check value and the first check value are compared and whether the second check value and the first check value are same or not is determined, and if the second check value and thefirst check value are same, the image data are considered complete. The method not only checks the content in each data packet, but also checks the combination and combination order of each data packet, the failure of a screen caused by the wrong combination and combination order of the data packets is effectively avoided, and the image display quality of the receiving terminal is improved.

Description

technical field [0001] The invention relates to the technical field of endoscopes, in particular to a picture integrity inspection method, a communication device and a capsule endoscope system. Background technique [0002] The capsule endoscopy system uses data packets as the unit in the wireless transmission of picture information. Generally, the data verification method is used to check the error code of each data packet to ensure the correct integrity of the data of each data packet. However, in practical applications, a picture is composed of many data packets. Even the data verification method of wireless transmission can ensure that the codeword of each data packet is correct, but if the receiving end combines multiple data packets into a picture Errors in the process, such as mixing the data packet of the previous picture into the current picture, will still affect the reorganization of the current picture, resulting in a blurry screen. [0003] The Chinese patent w...

However, this patent cannot rule out that data packets with the same sequence mark but belonging to different pictures cause interference and influence on the data packet reassembly of the picture, so that there are loopholes in the integrity detection of the picture, and at the same time, adding a sequence mark to each data packet increases the The length of the data packet increases the amount of data transmission and reduces the real-time performance of the system
