Embodiment Construction

[0069] The technical solution of the present invention will be described in detail below in conjunction with the drawings and embodiments.

[0070] At present, with the construction of digital cities for many years, 3D GIS data has gradually become a major data source, and indoor models are also important information. GIS is a geographic information system. The invention proposes to use the indoor three-dimensional GIS to provide data support for estimating the topological relationship between cameras, and it is a robust method to estimate the topological relationship between cameras based on the three-dimensional GIS. During specific implementation, the technical solution of the present invention can adopt computer technology to realize the automatic operation process. see figure 1 , the flow process of the method provided by the embodiment includes the following steps:

[0071] Step 1: With the auxiliary support of the 3D GIS model, establish the connectivity matrix betwee...

Abstract

The invention discloses a non-overlap vision field trans-camera indoor pedestrian target tracking method and a non-overlap vision field trans-camera indoor pedestrian target tracking system. The non-overlap vision field trans-camera indoor pedestrian target tracking method includes establishing an inter-camera communication relation matrix under the assistant support of a three-dimensional GIS (geographic information system) model; performing single-camera target tracking on a to-be-tracked pedestrian target selected by a user to acquire a pedestrian target sample image; judging whether or not the to-be-tracked pedestrian target leaves the vision field of a current camera; if yes, stopping single-camera target tracking based on the current camera, issuing a pedestrian target matching instruction to a node of the current camera and all adjacent nodes communicated with the node according to the communication relation matrix, and determining a target matching task start moment and a target matching task stop moment; performing pedestrian detection on shot videos, of all cameras receiving the pedestrian target matching instruction, from the target matching task start moment respectively. A reliable real-time technical scheme is provided for non-overlap vision field trans-camera indoor pedestrian target tracking and matching.

Description

technical field [0001] The invention belongs to the technical field of visual tracking, and in particular relates to a technical solution for tracking and matching pedestrian targets in multi-camera non-overlapping indoor viewing areas with the assistance of three-dimensional GIS information. Background technique [0002] With the development of video surveillance technology and people's increasing requirements for the intelligence of surveillance products, multi-camera target tracking technology has become a focus of attention. Compared with the limited field of view of single-camera surveillance, multi-camera breaks through the limitation of surveillance field of view. Therefore, multi-camera target tracking can be applied to wide-area video surveillance to meet actual needs. Multi-camera target tracking can be divided into overlapping view target tracking and non-overlapping view target tracking according to whether the monitoring fields of view overlap between cameras. ...
