The invention relates to the technical field of video investigation, and provides a face information structuring method for video investigation. The face information structuring method comprises the steps of: S1, acquiring a face from a video to be investigated, and marking face information; S2, subjecting the marked face information to face feature extraction, transmitting face features to a faceinformation structuring network for training, and generating a face information structuring model; S3, transmitting the face information to be structured into the face information structuring networkby means of the face information structuring model, so as to obtain a face information tag corresponding to the face information; S4, and performing face screening and investigation according to theobtained face information tag. According to the face information structuring method, the face information structuring model is generated by adopting the face information structuring network, the faceinformation tag is obtained thereby, the face information is directly subjected to face sample marking in video monitoring, the operation is simple, the environmental adaptability to actual video investigation is better, the robustness is better, and the face information structuring method is more practical in actual combat.
Description
technical field [0001] The invention relates to the technical field of video investigation, in particular to a face information structuring method for video investigation. Background technique [0002] With the rapid development of science and technology, intelligent video surveillance technology is widely used in public security criminal investigation business. It has become an important means of criminal investigation technology to record pedestrian and vehicle behavior through video recording, and to find and track suspected targets from video. In the actual process of handling a case, when the staff locks the suspect or the suspect vehicle, it is necessary to trace the suspect's action route from the crime scene and nearby areas. However, it is very difficult to manually find the suspect from the massive surveillance video. The work is not only time-consuming but also easy to miss the target. Contents of the invention [0003] The purpose of the present invention is t...
