Embodiment Construction

[0020] image 3 Be the working flow chart of the present invention, as shown in the figure, the specific implementation mode of the present invention comprises the following steps:

[0021] Step 1: Reconstruct the static 3D visual scene. For static objects such as buildings and related facilities, use a 3D laser scanning system (such as a Leica scanner) to intensively record the surface 3D coordinates, reflectivity and texture information of static objects in the target site, and make a real 3D record of the monitoring area. And the creation of static models is assisted with relevant available imagery and information. Thus, a static three-dimensional visual scene is constructed.

[0022] Step 2: Configure RGB-Depth and other cameras. According to the functional parameters of cameras such as RGB-Depth, the positions and attitudes of the cameras are reasonably configured in the monitoring area, so that the monitoring ranges of all cameras can be combined to cover the monitori...

Abstract

The invention relates to a three-dimensional visual monitoring system based on a novel RGB-Depth camera. The RGB-Depth camera is adopted, a static three-dimensional model rebuilding and dynamic personnel restoring method is used, three-dimensional scene information in a monitoring place is reproduced, and a user can watch a highly-simulated three-dimensional virtual scene at any visual angle. The three-dimensional virtual scene comprises static three-dimensional models and further comprises dynamic three-dimensional models of moving personnel and the like. The system comprises data obtaining devices of the RGB-Depth camera and the like, client computational nodes for obtaining data, a network communication platform, an information comprehension integration service platform and a display platform of the three-dimensional virtual scene. A specific implement method comprises the steps of rebuilding a static three-dimensional visual scene, configuring cameras of the RGB-Depth camera and the like, setting up a three-dimensional visual monitoring system body, generating three-dimensional templates of moving personnel entering a monitoring area, generating dynamic three-dimensional models of personnel in the monitoring area in an on-line mode, displaying a three-dimensional visual monitoring scene in a real-time mode, and carrying out intelligent monitoring services.

Description

technical field [0001] The present invention belongs to the general image data processing field, focuses on a new generation of three-dimensional visual monitoring, and relates to a three-dimensional virtual scene and an interactive display method of a monitoring area based on a new RGB-Depth camera. Background technique [0002] Three-dimensional visual monitoring is an important issue in the field of general image data processing. It is a key technology for security monitoring and the basis for many application issues such as security in key areas such as safe cities, military and justice. [0003] In 3D visual monitoring, for each detection scene, the user can set a highly simulated 3D virtual scene viewed from the perspective of the camera. The 3D scene includes not only static 3D models of buildings and related facilities in the monitoring area, but also dynamic 3D models of active people in the area. [0004] The invention further promotes the development of security ...
