Embodiment Construction

[0022] In order to realize the fusion of video and 3D model in a complex environment, the present invention firstly extracts and optimizes the texture and scene structure information of the 3D model, then calculates the scene structure invariant feature of the video image in real time, and establishes the matching relationship between the scene structure invariant feature and the 3D model , and finally use 3D projection technology to realize the seamless fusion of panoramic video and 3D model. Specifically include the following steps:

[0023] Step 1: Build a video monitoring management system, the video monitoring management system includes a media control module, a video forwarding module, a video storage module, a resource request module, and a communication control module, wherein,

[0024] The media control module is the core service in the overall scheme of the AVSS video monitoring management system, which can support multi-level and multi-domain, and is used to manage ...

Abstract

The invention discloses a registering method of a controllable vidicon surveillance video and a three-dimensional model in a complex scene. The Registering method of the controllable vidicon surveillance video and the three-dimensional model in the complex scene includes that firstly, a video monitoring management system is constructed, and the video monitoring management system comprises a media control module, a video transmitting module, a video storing module, a source request module and a communication control module; secondly, the three-dimensional model of a surveillance region is established, and the three-dimensional model in the surveillance region is constructed through three-dimensional modeling technology; thirdly, the vidicon is calibrated, relative locations and angles in the model of the vidicon are calibrated, and the registering of the vidicon video and the three-dimensional model is achieved.

Description

technical field [0001] The invention relates to a registration method of an image and a three-dimensional model. Background technique [0002] As the society pays more and more attention to and improves the security requirements, monitoring is more and more widely used in the real world, and its role is becoming more and more important. In traditional monitoring, monitoring personnel are required to continuously monitor the screen in real time, manually interpret the video information obtained, and then make corresponding decisions. However, it is a very heavy task for monitoring personnel to stare at numerous video monitors for a long time and boringly, especially in places where there are many monitoring points, it is almost impossible for monitoring personnel to perform complete and comprehensive monitoring. This not only causes a huge waste of manpower, but also easily leads to missed reports due to the slackness of the monitoring personnel. In some occasions that are s...
