The invention relates to the technical field of security and protection monitoring, in particular to a security and protection video monitoring method based on mixed feature recognition. The method comprises the following steps: firstly, constructing a historical traffic congestion data set and a real-time traffic congestion data set, wherein the data sets comprise vehicle appearance features, vehicle motion states, pedestrian states and environment state multi-dimensional features; and constructing a first traffic congestion probability prediction model and a second traffic congestion probability prediction model according to historical data. Secondly, analyzing real-time vehicle movement and pedestrian state data to obtain a first prediction probability of traffic congestion; and analyzing the influence of the vehicle appearance characteristics and the environmental state data on the vehicle speed, and further influencing a second prediction probability of traffic congestion. And finally, the comprehensive prediction probability of traffic congestion is calculated through multi-feature fusion, and light and sound are used for early warning based on the probability to prompt that the traffic congestion is about to occur or possibly occurs, so that the prediction precision of the traffic congestion is effectively improved, and intelligent support is provided for traffic management and dispersion.

    本发明涉及安防监控技术领域,具体为一种基于混合特征识别的安防视频监控方法。首先构建历史交通拥挤数据集和实时交通拥挤数据集,数据集包括车辆外观特征、车辆运动状态、行人状态及环境状态多维度特征;根据历史数据构建第一和第二交通拥挤概率预测模型。其次通过对实时车辆运动和行人状态数据进行分析,得到交通拥挤的第一预测概率;分析车辆外观特征和环境状态数据对车辆速度的影响,进而影响交通拥挤的第二预测概率。最后通过多特征融合计算交通拥挤的综合预测概率,基于概率使用灯光和声音进行预警,提示即将、可能发生交通拥堵,从而有效提高交通拥堵的预测精度,为交通管理和疏导提供智能化支持。
