Problems solved by technology

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". A single application of face feature information, such as face recognition unlocking, face recognition access control, face recognition attendance, etc., each system is highly independent, and has not realized multi-information, multi-technology, multi-field technology in the true sense Integration

Embodiment Construction

[0037] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific project embodiments.

[0038] Project introduction: Green Sky City is a land-saving three-dimensional building, covering an area of ​​121,500㎡, and the total construction area of ​​the main building is 708,300㎡. Design 242 villas, 1 commercial catering building, 1 fitness and entertainment building, 1 toddler and children's playground building, 1 elderly housing building and 4 three-dimensional parking lots. The maximum number of parking spaces can reach 3392 cars. The core complex of public buildings. The main building has seven floors, the second floor is 13m above the ground, the second to seventh floors are all 30m high, and the total height is 169m. The rectangle is 450m×270m, with a north-south span of 450m and an east-west span of 270m. There are 1.2m protective railings on the periphery of each floor, and a "sky garden" on the top floor.

Abstract

The present invention proposes a cloud face recognition and positioning method based on building information model, including: construction of cloud BIM information database; face feature information extraction and cloud storage; cloud face recognition implementation; terminal functional subsystem access to cloud system. The present invention is jointly completed by the cloud multi-source information database, cloud computing unit, cloud management platform, external camera device, etc., and can effectively solve the problems of slow speed, low information integration, small application range and serious waste of resources in the existing face recognition technology. Information cannot be shared and other issues can be widely used in urban and rural building logic access control, smart attendance, camera positioning, personnel search management, facial recognition payment, 120 ambulance and other aspects.

Description

technical field [0001] The invention relates to interdisciplinary fields such as civil engineering, image processing, and information technology, and in particular to a cloud face recognition and positioning method based on a building information model. Background technique [0002] Building Information Modeling (BIM, Building Information Modeling) is the Internet era, based on 3D digital technology, it integrates the information model of the whole life cycle of construction project planning, survey, design, construction, operation and maintenance, including the geometry, physics, Performance, process and other information. At present, technologies integrated with BIM continue to emerge, such as BIM+VR, BIM+GIS, BIM+3D printing, etc. [0003] Face recognition technology is a biometric technology for identity recognition based on human facial feature information; image acquisition devices such as cameras are used to collect images or video streams containing human faces, and...
