一种基于规则证据图的视频行为核验方法和系统

本发明公开了一种基于规则证据图的视频行为核验方法和系统。该方法包括：获取待审视频及行为规则包，解析视频获取媒体索引，构建规则证据图；根据规则证据图生成第一视频处理计划，执行多模态识别生成视频证据事件并构建多模态视频证据时间线；通过图匹配计算规则证明评分和负证据覆盖率，确定各规则节点的初始证明状态；证据不足时生成规则缺口向量，在候选时间窗口内提高采样密度生成第二视频处理计划，执行后更新证据时间线并重新计算评分，输出最终证明状态。本发明通过规则证据图驱动自适应抽帧和多模态联合验证，结合负证据覆盖率与规则缺口反馈机制，提高了短时动作召回率和核验准确性，降低了计算成本，实现了核验结论的可追溯与可复核。
