Embodiment Construction

[0060] figure 1 Explanation: The present invention consists of a camera unit comprising two cameras with common resolution and high resolution respectively, a camera fine-tuning control unit, two video data acquisition units, a real-time data processing unit, a data storage unit, and a display unit, a playback data processing unit.

[0061] figure 2 Description: Step 1: Directly record the continuous video input from the normal resolution camera to the storage unit;

[0062] In the second step, according to image 3 The algorithm shown, determines the changing value of the scene.

[0063] The third step is to judge whether the scene change value exceeds the preset threshold d1, which is calculated as follows. If it is not exceeded, this processing ends, otherwise go to the fourth step.

[0064] d1=total number of pixels in the image*r

[0065] r=5%-10%, can be adjusted manually.

[0066] The fourth step is to directly save the video of the current high-resolution camer...

Abstract

The invention discloses digital video intelligent monitoring equipment based on a dual camera and a data processing method. The digital video intelligent monitoring equipment is composed of two camera units, a camera trimming control unit, two video data acquisition units, a data storage unit, a display unit and a dump data processing unit, wherein the camera units are respectively provided with high resolution and common resolution. The invention adds the high-resolution camera, controls the high-resolution camera and intelligently monitors the monitoring area image in real time so as to store the image with larger variation in the monitoring area at the data rate of 2 frames / second to furthest reduce the problem of data volume increase brought by adding the high-resolution monitoring image; and meanwhile, the requirement of distinguishing high-resolution image details to the monitoring area is ensured, and the monitoring efficacy is greatly improved.

Description

technical field [0001] The present invention relates to a digital video intelligent monitoring device, specifically a monitoring device with dual cameras, through real-time processing of a low-resolution monitoring video, to obtain a high-resolution video image capture timing indication, and to capture a high-definition digital video image according to the indication A digital video monitoring device with certain intelligence and a data processing method thereof. Background technique [0002] The use of digital video surveillance equipment has become very popular at present, and is widely used in building monitoring and intersection and road monitoring, but the resolution of these videos is generally low (usually VCD resolution), which has led to the widespread use in current applications. A problem of , that is, when you need to check the details of the related video, because the resolution of the video is low, many details are very blurred and cannot be distinguished even ...
