[0004] At present, for the target comprehensive cognition method, the invention patent with the application number of 201110338382.5 discloses a target comprehensive recognition method based on uncertain reasoning, but this method uses a variety of reconnaissance equipment to detect the same target, in the multi-sensor fusion system The identification of reconnaissance targets is realized based on uncertain reasoning rules, focusing on the analysis and processing of signal-level intelligence to achieve accurate identification of military targets, but it does not achieve comprehensive cognition of targets, and assists decision-making in the field of national social public security In terms of support, it is impossible to realize the comprehensive cognition of the targets of key figures such as terrorists and important control personnel
The comprehensive cognition method based on key figure target recognition has not been seen yet.

Embodiment Construction
[0032] Embodiments of the present invention will be described in further detail below in conjunction with the accompanying drawings.
[0033] like figure 1 As shown, a kind of comprehensive cognition method based on key character target recognition of the present invention comprises the following steps:
[0034] S1: Recognize key figures and targets under high noise and low resolution conditions;
[0035] In the embodiment, the identification of important persons and targets under the conditions of high noise and low resolution described in step S1 is realized by image target recognition technology based on deep learning; specifically includes:
[0036] Establish and train a deep convolutional neural network model based on image data of key target persons;
[0037] Extract the hierarchical features of the target from the image to be tested, obtain the multi-dimensional feature description of the target, and realize the robust feature extraction and final automatic recognitio...

The invention discloses a comprehensive cognition method based on key person target recognition. The comprehensive cognition method comprises the following steps: recognizing key person targets underconditions of high noise and low resolution; constructing a key person target knowledge base and converging knowledge, and describing a target social attribute, an activity rule and a behavior habit association relationship; and associating and verifying multi-source information data with the image key person target. According to the comprehensive cognition method, a comprehensive target cognitivemethod is constructed by taking image key person target recognition as a main line, taking a target knowledge graph association relationship as an auxiliary line and taking other open source text news information and professional information as a certificate. Compared with the prior art, the comprehensive cognition method solves the key person target recognition problem in a complex background image, also solves the problems of overload of mass data information and focusing of target knowledge, and provides technical support for accurate target cognition in the field of national social publicsecurity.
Description
technical field [0001] The invention belongs to the technical field of target recognition and cognition, and in particular relates to a comprehensive cognition method based on the target recognition of important persons facing the field of social public safety. Background technique [0002] Facing the identification and cognition needs of key figures and targets in tasks such as counter-terrorism, anti-interruption and defense in the field of national social public security, the existing technologies mainly include video image target recognition, character portraits and other technologies. Among them, the video image target recognition technology is mainly used for real-time monitoring and deployment and control of the scene to realize the target recognition of key figures; the portrait of the person is used to describe the social attributes, activity rules, behavior habits and other related relationships of people, and provide support for analysis and judgment such as early ...
