Problems solved by technology

The indoor ambient light changes frequently due to the flickering of the light source caused by the dynamic information played by the TV. If the ViBe technology is directly used for dynamic target detection, the correct detection rate of the dynamic target may be reduced due to the inability of the background model to be continuously updated.

Embodiment Construction

[0039]In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific illustrations.

[0040] see figure 1 , which is shown as a flow chart of the present invention for dynamic target detection. As can be seen from the figure, the entire detection process includes five steps: 1. Image frame preprocessing, 2. Background model initialization, 3. Luminance flicker detection and correction, 4. Background model update, and 5. Post-processing.

[0041] The following is attached figure 1 The scheme of the present invention is further expanded and described.

[0042] Step 1. Image frame preprocessing;

[0043] This step starts with the collection of image sequences, because the IP camera collects corresponding image data, and transmits the collected image sequence data through the network. Due to the transmission through the network, t...

Abstract

The invention discloses a dynamic target detection method based on brightness flicker correction and an IP camera. Firstly, the brightness flicker correction technology is utilized for correcting a global or local flicker in a frame image with the brightness flicker, and then a dynamic target is classified out through a background model based on the random theory. The reliable dynamic target detection method is provided under the condition of various and changeful light sources in the indoor environment. According to the scheme, the method can be applicable to intelligent monitor on the occasions of various complex light sources like televisions and electric lamps under the indoor environment.

Description

technical field [0001] The invention relates to the technical fields of computer vision and digital video restoration, in particular to a detection technology of a dynamic target in an indoor environment based on brightness flicker correction and using an IP camera as a carrier. Background technique [0002] With the development of network technology, intelligent video surveillance is developing from analog surveillance to all-IP network intelligent digital surveillance. Intelligent video surveillance is the use of computer vision technology and pattern recognition technology to process, analyze and understand video signals without human intervention, and based on this, it automatically analyzes the image sequence and locates changes in the monitoring scene. Identify and track, analyze and predict the behavior of the target on this basis, can issue an alarm or provide useful information in time when an abnormal situation occurs, effectively assist security personnel to deal ...
