Video monitoring method and system

Abstract

The invention discloses a video monitoring method and system, and relates to the technical field of video monitoring. The method comprises the following steps: obtaining a door region image in real time; when a moving target is detected, preprocessing the door area image to obtain a binary image; judging the direction of a moving target according to the binarized image, and judging whether a user exists in an area or not according to the direction of the moving target; if yes, starting an air conditioning system; if not, closing the air conditioning system. According to the method, the effective target can be accurately recognized, so that starting and stopping of the air conditioner are more accurately controlled, the temperature of the air conditioning system is adjusted and controlled by calculating the area of the target object, the automation degree is high, energy waste is avoided, the energy-saving effect is achieved, and production and life are facilitated.

Description

technical field [0001] The present invention relates to the technical field of video monitoring, and more specifically relates to a video monitoring method and system. Background technique [0002] At present, with the improvement of living standards, the scale of public buildings tends to be huge, and there are more and more tall buildings. There are many technical difficulties in the actual construction process, especially the construction of the HVAC system. Tall and large space buildings have the characteristics of high height and large volume. If cooling or heating the entire building space, it needs to consume a lot of energy. In addition, the high concentration of people in tall and large buildings, the concentrated and uncontrollable use time may easily cause the air conditioner to still run during idle time or space, wasting resources and energy consumption. With the rapid development of science and technology, real-time manual control is not required, and it is m...

Problems solved by technology

[0003] However, in the prior art, the monitoring of the air conditioner by video technology is mainly a static vision method. The camera installed in the area can judge whether there is a user in the area space, so as to control the start and stop of the air conditioner, but it can only detect whether there is a user. It is not possible to accurately determine the flow direction of the user, and there may be cases where the user only stays for a while and then leaves, which will reduce the accuracy of monitoring, resulting in the inability to correctly control the air conditioner, and the power consumption of the air conditioner is high. Whether someone controls the start and stop of the air conditioner will consume a lot of power and affect the service life of the air conditioner
