Problems solved by technology

However, in the working mode such as offline video recording, the monitoring terminal is generally in a state of unmanned operation, and when the monitoring scene changes, the monitoring terminal cannot adjust itself according to this change
For example, as the intruding object continues to move, if the camera is always facing the same direction, the moving object is likely to be out of the range covered by the camera, so the video file obtained by recording is less effective

Embodiment 1

[0038] In this embodiment, when the wireless monitoring terminal performs video recording, the current position of the moving object and its movement trend are judged according to the real-time image frame, and the camera is driven to perform necessary steering as required, so that the moving object can always be in the center or at the center of the recording scene. Near the central area. Specifically, the method includes the following steps:

[0039] Step 1, the monitoring terminal enters the state of self-recording, and can continuously obtain real-time still image frames.

[0040] Step 2: Obtain still image frames at fixed time intervals. After having temporally adjacent multi-frame images, judge whether there is motion or not based on the comparison of pixel differences between adjacent frames. If motion occurs, judge that the moving object is currently in the camera. The position in the field of view and its tendency to move.

[0041] Step 3. In the case of motion, pre...

Embodiment 2

[0043] image 3 is a detailed structural block diagram of the monitoring terminal according to embodiment 2, wherein:

[0044] The camera module 301 includes software and hardware.

[0045] The camera module 302 includes a software part and a storage part for saving video recordings.

[0046] Motion tracking judgment module 303 .

[0047] The camera direction adjustment driver module 304 includes software, hardware drivers and electromechanical parts for rotating the camera.

[0048] The following is based on image 3 Explain that the basic operation mode of this method is as follows:

[0049] (1) The wireless monitoring terminal finds that there is an object intrusion through the motion detection method, and the video recording starts. The camera module 301 continuously provides still image frames, and the camera module 302 performs video encoding using the still image frames, and writes the encoded data into a storage device.

[0050] (2) The camera module 301 also con...

Embodiment 3

[0053] This embodiment describes in detail the method for judging the moving direction of the object, and specifically explains how to judge the moving direction of the object between two moments based on the pixel information of the image frame, and predict the position at the next moment. In order to realize the above process, it specifically includes three aspects, namely, classification of pixel change types, position judgment based on regional pixel changes, and position prediction at the next moment, which are explained below:

[0054] (1) Definition of pixel change type

[0055] According to the requirements, the most suitable pixel information expression is the Y value in the YUV format pixel information, and Y is defined as follows:

[0056] Y=0.299R+0.587G+0.114B

[0057] Since the possible value ranges of R, G, and B are all 0-255, the range of Y value is also 0-255.

[0058] From the definition, Y has expressed the color information of the object. Although theor...

Abstract

A video monitoring method and monitoring terminal are provided in the invention. The method includes the following steps: a monitoring terminal determines that a motion object exists in the view based on the obtained image frames at different time points; said monitoring terminal estimates the motion tendency of said motion object; said monitoring terminal adjusts the camera angle of the monitoring terminal based on said motion tendency. The invention solves the problem of the worse effect that the fixed cameras lead to in the relation art. And the monitoring terminal can adjusts the camera angle to track the motion object in the view automatically, in order to obtain the best monitoring effect.

Description

technical field [0001] The present invention relates to the communication field, in particular, to a video monitoring method and a monitoring terminal. Background technique [0002] At present, wireless monitoring terminals based on wireless networks such as Wideband Code Division Multiple Access (WCDMA) have been widely used, and users can use mobile terminals (for example, mobile phones) or PCs to access monitoring terminals at any time. Perform real-time video surveillance. [0003] As users have higher and higher functional requirements for real-time video monitoring, at present, wireless monitoring terminals can also perform offline work without user intervention. Or the monitoring terminal with motion detection function will automatically start video recording after finding an abnormal intrusion. [0004] As mentioned above, when the current wireless monitoring terminal independently performs video recording, the operations that can be performed only include starting...
