Embodiment Construction

[0006] In the area to be monitored by the camera erection in the present invention, the camera is connected to the main control computer through a data cable. The whole system is mainly composed of three parts: (1) detection of the light spot; (2) analysis of the motion law of the light spot; (3) display and alarm based on different platforms. The simple working process of the system is shown in Figure 1.

[0007] Usually, the detection methods of light point features in video are: (1) background subtraction method, which uses the difference between the current image and the background image to detect the moving area; (2) time difference method, in a continuous image sequence two or three A pixel-based time difference is used between adjacent frames to obtain a frame difference image, which is post-processed to extract the light spots in the image. (3) Detect the brightness of the image, and the grayscale is greater than (or less than, as defined by the black and white value)...

Abstract

The invention discloses an automatic monitoring system of indoor places in night environment based on intelligent video. Generally monitoring cameras can provide little information when it is at night and has no illumination. The system of the invention utilizes characteristic analysis on light spots to indirectly judge personnel intrusion If light spots with regular movements are found, a message is sent to terminal equipment of a house owner, a security guard or a policeman platform in a wired or wireless way, wherein the terminal equipment comprises a mobile, a computer screen, a tablet pc, etc. The system can be applied to monitoring for indoor places which are equipped with cameras, such as homes, offices, hotels, etc.

Description

technical field [0001] The present invention belongs to the field of intelligent video. Through the intelligent analysis of the camera image, the analysis of the intrusion behavior of indoor places in the dark environment is realized, and the timely detection and alarm of the illegal intrusion of people at night can be achieved. Background technique [0002] With the large-scale camera industry, the application of cameras has become popular; a large number of cameras are widely used in public security and smart home monitoring. It is obviously impossible to manage these numerous cameras manually and from time to time. In addition, in the civilian market such as smart home, the traditional monitoring method using the large screen in the control room is not suitable for the needs of ordinary users. The future monitoring terminal should be mobile devices such as mobile phones. Therefore, the camera needs to be able to intelligently judge the appearance of the target of interes...
