Research on 3D Intelligent System Based on Network Information Technology

In order to overcome the “semantic gap” and other problems faced by traditional video processing technologies, the information contained in the patio-temporal subspace of the 3D model is used for video processing and analysis, and an intelligent video surveillance technology guided by the spatiotemporal subspace of the 3D model is proposed. First, the 3D target model is matched from the video under the guidance of the body shape subspace. Secondly, we extract video events under the guidance of the patio-temporal subspace of the 3D model: surveillance object video + 3D model spatiotemporal subspace
