Automatic monitoring system based on three-dimensional scene modeling

Abstract

The present invention provides an automatic monitoring system based on three-dimensional scene modeling. The automatic monitoring system based on three-dimensional scene modeling is characterized by comprising a monitoring module, a three-dimensional scene module, a matching module and a management module. The monitoring module is used to acquire and store the video information and the position information corresponding to each camera, the three-dimensional scene module is used to carry out the three-dimensional modeling on a monitoring area to construct a three-dimensional map scene, and the matching module is used to project a video to the three-dimensional map scene by a projection method to carry out the matching alignment, and automatically prompt to the management module after discovering an abnormal phenomena. The system of the present invention can prompt and alarm automatically when discovering the abnormal phenomena, and can generate a three dimensional panorama monitoring picture of the large-range monitoring area.

Description

[0001] technical field [0002] The invention relates to the monitoring field, in particular to an automatic monitoring system based on three-dimensional scene modeling. [0003] Background technique [0004] Surveillance system is one of the most widely used systems in security systems, among which video surveillance is the most common. Video surveillance is an important part of the security system. Video surveillance is widely used in many occasions because of its intuition, accuracy, timeliness and rich information content. At present, the traditional two-dimensional video surveillance is the most widely used in the market, and the surveillance video of a certain area is obtained through cameras in different positions. This monitoring method requires personnel to pay attention to the video information obtained by each camera at all times. A slight negligence will cause monitoring omissions, which will easily cause personnel fatigue and result in ineffective monitori...

AI Technical Summary

Problems solved by technology

This monitoring method requires personnel to pay attention to the video information obtained by each camera at all times. A slight negligence will cause monitoring omissions, which will easily cause personnel fatigue, resulting in ineffective monitoring.

At the same time, the internal structure of many monitored places is often very complex. The existing two-dimensional video surveillance mode is not three-dimensional. Which part of the monitored site is located affects the user's accurate judgment and timely disposal

Therefore, the traditional two-dimensional video surveillance is not conducive to the user to directly observe the specific location of the suspicious object, the monitoring efficiency is low, and the monitoring is not effective.
