Embodiment Construction

[0025] Based on the above, an indoor face recognition and positioning method based on a panoramic camera is proposed in the present invention. The present invention will be further described in detail below in conjunction with the accompanying drawings and specific case implementations.

[0026] 1 Model analysis and equipment erection

[0027] 1.1 Use BIM, CAD, 3DMax and other three-dimensional modeling software to establish a three-dimensional model of the building (this operation uses the xyz three-axis coordinates of the software itself, which are the default coordinates of the software and do not need to be adjusted);

[0028] 1.2 Carry out building layering on the established 3D model, and mark each floor slab, which is conducive to the visual analysis of each floor in the next step and the plane positioning of the camera installation point;

[0029] 1.3 Run visibility analysis software such as Autodesk Ecotect Analysis to perform visual analysis on the internal space of ...

Abstract

The invention provides an indoor face recognition and positioning method based on a panoramic camera. The technical method comprises the following steps: building internal space visual analysis, panoramic camera erection, face recognition, positioning calculation and positioning output. 3-D digital model of that panoramic camera and the building, The invention is characterized in that the indoor space analysis is carried out through the three-dimensional digital model of the building, the fixed point position of the panoramic camera is selected, the panoramic camera is installed and debugged,the face is monitored and detected, the face position is recognized through the geometric relationship between the camera and the monitored person, and the accurate positioning of the indoor face is realized. The invention does not rely on a wearable device, The signal base station can effectively solve the problems that the existing indoor positioning method needs to cooperate with mobile equipment, is susceptible to electromagnetic interference, has poor precision, is difficult to accurately dock with a specific person, has small application range, wastes resources seriously, and can be widely used in indoor navigation, loss prevention, security management, suspect tracing, 120 ambulance, and other aspects.

Description

technical field [0001] The invention relates to multidisciplinary fields such as civil engineering, computer network, image processing, and information technology, and in particular to an indoor face recognition and positioning method based on a panoramic camera. Background technique [0002] Face recognition is a biometric technology for identification based on human facial feature information. A series of related technologies that use a video camera or camera to collect images or video streams containing human faces, automatically detect and track human faces in the images, and then perform facial recognition on the detected faces. At present, face recognition technology is widely used in shopping malls, office buildings, railway stations and other places, but the main basic pain point is that "each element of information is isolated and closed, and the recognition mode is traditionally single", that is, it does not break through the traditional concept, but only in the fi...
