[0063] 1. Summary of Feature Points
[0064] As mentioned in the content of the invention, the feature points are the core of this patent, and the size, position, and relative proportions of certain organs are unique and invariant in the face within a specific triangular area; while the proportions of other organs, although There are changes, but they can maintain relative stability. According to the change degree of the size, position and relative proportion of these organs, this patent divides them into three categories:
[0065] A) Unique invariant relationship:
[0066] distance between eyes;
[0067] The proportional relationship between the pupils of the eyes and the tip of the bridge of the nose
[0069] Proportional relationship between the arc length of the bridge of the nose and the width of the nose
[0070] geometry of the cheekbones;
[0071] distance between eyebrows and upper lip;
[0072] the distance between the corners of the...

This patent discloses a real-time face recognition monitoring system, including a monitoring system and a face recognition system. The video signal collected by the monitoring system is compressed by the machine and input to the face recognition system through the network; the face recognition system mainly includes a face recognition system. Capture engine, interference restoration engine, face modeling engine, face comparison engine, database; the computer is connected to the monitoring system through a switch; the photo library stores the original comparison photos; the face capture engine collects and obtains video or images through video input devices The information contains 2D portraits with facial biological characteristics; the interference restoration engine corrects and restores the captured 2D portraits; the face modeling engine performs 3D expansion and 3D modeling on the collected 2D portraits that meet the modeling conditions to generate 3D Feature value; the face comparison engine compares the 3D feature value generated by the acquired 2D portrait with the 3D feature value generated by the photo in the photo library to obtain the comparison result.
Description
technical field [0001] The invention relates to a computer-aided biological feature identification system, and more specifically relates to a real-time face recognition monitoring system. Background technique [0002] With the rapid development of the economy, the density of the population is further concentrated, especially with the severe situation of anti-terrorism, we are facing various public security situations. In this case, the monitoring of public places and the identification of people in public places are even more important. [0003] In traditional video surveillance systems, when there are many objects of special concern, it is impossible to give early warning even when someone is watching the surveillance screen; because in a short period of time, it is impossible for people to have a deep understanding of everyone. I can only pay attention to 2-3 people at most. Coupled with human factors such as personnel changes and fatigue, it is difficult for traditional...
