Faced with large amounts of complex environmental monitoring data, traditional manual analysis methods are not only inefficient, but also difficult to ensure the accuracy and timeliness of the analysis. Traditionally, photographers need to make settings based on experience and on-site environment, which not only requires photographers to have rich experience and keen insight, but also easily leads to inaccurate parameter settings due to human factors. Due to the complexity and unpredictability of environmental factors, some dangerous or unsuitable situations may be encountered. Traditional safety protection measures often rely on human judgment and intervention, and there are problems of delayed response and inaccurate judgment. Summary of the invention
