Video monitoring data storage method based on block chain

The invention relates to the field of video data processing, in particular to a video monitoring data storage method based on a block chain, and the method comprises the steps: obtaining a target image corresponding to a target frame, a gray value of a sub-image based on the target image, a clustering number in an RGB space, and an LBP feature value corresponding to each pixel point according to video monitoring data, the method comprises the following steps: acquiring a target image, calculating a detail retention degree corresponding to the target image, inputting the detail retention degree into a preset compression parameter calculation model, calculating a compression parameter corresponding to the target image, compressing video monitoring data, confirming compressed data corresponding to the video monitoring data, and finally uploading the compressed data corresponding to the video monitoring data to a data server. And storing the video monitoring data. Each frame of image is compressed through the com
