Problems solved by technology

The above-mentioned types of fast retrieval methods are usually complex to implement, and the fast retrieval objects are usually scene-based database pictures such as CIFAR-10 and INRIA Holidays, which are usually not suitable for fast retrieval of face images, and because faces are easy to The feature extraction and description of human faces are easily affected by expressions, lighting, etc., especially in large-scale face databases. Face poses and expressions change drastically, and it is difficult to extract stable descriptors for fast retrieval. It is directly applicable to the current Fast retrieval methods for fast retrieval of faces cannot achieve accurate retrieval

Embodiment Construction

[0048] The present invention will be further described below in conjunction with the accompanying drawings and specific preferred embodiments, but the protection scope of the present invention is not limited thereby.

[0049] Such as figure 1 As shown, the steps of the intelligent video surveillance method in this embodiment include:

[0050] S1. Face real-time monitoring: real-time monitoring of the target video, real-time detection of human face image output from the video image;

[0051] S2. Image intelligent encoding: encoding the face image detected in step S1 to obtain the image encoding to be checked;

[0052] S3. Face quick retrieval: match and compare the codes of the image to be checked with the database codes obtained from the face images in the database in advance, and obtain the recognition result output.

[0053] In this embodiment, real-time face monitoring, intelligent image coding, and fast face retrieval are carried out in sequence to realize automatic face...

Abstract

The invention discloses an intelligent video monitoring method and device. The steps of the method include: S1. Real-time monitoring of the target video, real-time detection of human face image output from the video image; S2. Human face image detected in step S1. Encoding to obtain the code of the image to be checked; S3. matching and comparing the code of the image to be checked with the database code obtained by the face image in the database in advance to obtain the output of the recognition result; the device includes a face real-time monitoring module, an image intelligent coding module and Face fast retrieval module. The invention can realize intelligent video monitoring, improve the intelligent level of video monitoring, and at the same time greatly reduce the space occupied by video data storage and transmission.

Description

technical field [0001] The invention relates to the technical field of video monitoring, in particular to an intelligent video monitoring method and device. Background technique [0002] With the current increasing security requirements, the role of video surveillance systems is becoming more and more obvious. Traditional video surveillance is mostly used for video capture, storage, and playback, and it is difficult to play the role of early warning and alarm. Real-time monitoring requires humans to continuously monitor the video, resulting in a lot of waste of manpower and time. At the same time, with the explosive growth of data volume, The traditional monitoring mode has also been unable to meet the storage and transmission requirements for massive video data. The above-mentioned traditional video surveillance adopts the old mode of manual operation and post-event evidence collection, which has a low degree of intelligence, and there are many problems such as massive vid...
