Problems solved by technology
At present, the monitoring systems on the market all use 2-dimensional image display, which has many shortcomings such as being unable to adapt to close-range monitoring under high temperature conditions, and unable to monitor at monitoring angles that do not have installation conditions. With the development of video monitoring technology in my country development, a new technical solution is needed to make up for the deficiencies of existing technologies

Embodiment 1
[0026] 1. Establish a front-end image acquisition system, the front-end image acquisition system and transmission system include cameras, pan-tilts, and monitoring networks;
[0027] 2. Establish an image distance processing system in the computer: the image distance processing system is composed of a frame image extraction subsystem, a frame image comparison subsystem, a data operation processing subsystem and a data interface subsystem, and realizes distance calculation on images collected by the front end ;
[0028] The processing process of the image distance processing system: the distance calculation between the monitoring object or the environment and the collection point is performed by processing the collected image information of the same object or environment by different collection front ends, and the representation method of the 3D model will have complex The surface of a shape object is approximated by a polygonal patch;

The invention relates to a 3D (Three Dimensional) video monitoring method based on computer modeling. A hardware used in the method comprises a front-end image acquisition system and a transmission system. The method is characterized in that a monitoring camera is used for acquiring video image information; a computer is used as a processing platform so as to finish the conversion from images to a 3D model, and the 3D modeling, and update the content of the 3D modeling according to real-time video image information acquired by the camera; and simultaneously, the virtual monitoring is executed on a model by a simulated camera in the computer. The method has the beneficial effects of being capable of carrying out the 3D modeling by the computer, modeling historical records according to normal recorded videos, realizing the simulation on monitoring regions by combining with a digital sand table, finishing the bake simulation on complex environments with a small number of acquisition front ends, and being applied to detection in the complex environments.
Description
technical field [0001] The invention relates to the technical field of video monitoring, in particular to a 3D video monitoring method based on computer modeling. Background technique [0002] The monitoring system is composed of front-end acquisition system, transmission system and display system. It is a weak current system with the main functions of remote viewing of real-time conditions in the monitored area and video playback. At present, the monitoring systems on the market all use 2-dimensional image display, which has many shortcomings such as being unable to adapt to close-range monitoring under high temperature conditions, and unable to monitor at monitoring angles that do not have installation conditions. With the development of video monitoring technology in my country Development requires a new technical solution to make up for the deficiencies of existing technologies. Contents of the invention [0003] The purpose of the present invention is exactly at the...
