High-speed fault-tolerant image transmission method based on pest and disease damage research

Abstract

The invention relates to a high-speed fault-tolerant image transmission method based on pest and disease damage research. Specifically, images of crop diseases and insect pests are encrypted; the encrypted images of the crop diseases and insect pests are split according to a polynomial rule; the size of each split image information block is smaller than that of the original image; then, and the split image information blocks are sent to an image receiving end by the image sending end; after the image receiving end acquires the transmitted image information block, the image information block israndomly selected to recover the disease and pest image; when a recovered image is abnormal, the image information block is selected to recover the disease and pest image again until the encrypted image information is decrypted to obtain the disease and pest image. The method is reasonable in conception, simple in step, high in image transmission efficiency and low in probability that the image is attacked or damaged; the method has an image lossless recovery function, and is high in safety in the image transmission process.

Description

technical field [0001] The invention belongs to the communication field, and in particular relates to a high-speed error-tolerant image transmission method based on the research of diseases and insect pests. Background technique [0002] Agriculture is an important pillar of the national economy. With the development of science and technology, the modernization of agriculture has been continuously strengthened. The application of science and technology in agriculture has become more and more common, which not only saves manpower and material resources for farmers, but also facilitates the management of farmers and improves the The output of crops has increased the income of farmers and increased the connection between rural areas and cities. [0003] my country has a vast land area, and agriculture is an important part of my country's economy. At the same time, there are many types of crop diseases and insect pests, and the frequency of outbreaks is high, which limits the ou...

Problems solved by technology

[0007] The peak-to-average power ratio of COFDM technology is relatively large, and as the ratio increases, the power efficiency of the RF amplifier will decrease

And it is very sensitive to frequency shift and phase noise, and it is easy to cause the loss of transmission information during the transmission of image information, resulting in a large amount of loss

[0008] In the information transmission process of CDMA, due to the limitation of network bandwidth, the process of transmitting information often takes a long time, and it is easy to be attacked or damaged during the transmission process, and the visual effect often does not meet the user's expectations. Breakpoints and blind spots are more likely to appear in the application
