  • Patent number: 12118772
    Abstract: A human activity recognition fusion method and system for ecological protection red line is disclosed. The method includes: obtaining a pre-stage remote sensing image and a post-stage remote sensing image of a target ecological protection red line region, and performing a data pre-processing; inputting the pre-processed pre-stage remote sensing image and the post-stage remote sensing image into a human activity recognition model after a pre-training; identifying a human activity pattern of the target ecological protection red line region as a first detection result; segmenting, calculating and analyzing the latest image data corresponding to the target ecological protection red line region based on a geographical country situation data to obtain a change pattern as a second detection result; and fusing the first detection result and the second detection result to obtain a change detection pattern of the target ecological protection red line region.

  • Publication number: 20240276528
    Abstract: This application relates to a communication method and device. A first terminal device receives at least one message for reserving a resource, and the first terminal device determines, from S resources based on the at least one message, M resources whose signal strengths do not meet a first signal strength threshold. The first terminal device adjusts the first signal strength threshold if M does not meet a first resource quantity or S-M does not meet a first resource quantity. The first terminal device sends a first message to a second terminal device, where the first message indicates a resource determined based on an adjusted signal strength threshold, and the adjusted signal strength threshold enables M or S-M to meet the first resource quantity.
