Embodiment Construction

[0109] The overall process of the active video acquisition method based on binocular camera is as follows.

[0110] (1) Choose a camera with a fixed focal length as the main camera, choose a camera with adjustable PTZ parameters as the slave camera, and choose a high-performance DSP platform as the embedded processing platform; set the equipment parameters of the master and slave cameras (including lens focal length, Field of view, imaging device size) and installation location information are stored in the embedded processing platform, the video output of the main camera is connected to the embedded processing platform, and the control signal line of the slave camera is connected to the embedded processing platform.

[0111] (2) After the embedded processing platform obtains the surveillance scene video picture obtained by the main camera, it first uses the region motion feature extraction method based on edge features to extract the moving target region in the scene and the c...

Abstract

The invention discloses active video acquiring method and device based on binocular camera shooting. In the technical scheme, a main camera, a slave camera and an embedded intelligent analysis control system are installed in a same monitor scene; when a system works, a valuable target region which possibly exists is rapidly extracted from a monitor scene global video picture acquired by analyzingthe main camera by the embedded intelligent analysis control systems at the front end, control parameters needed by the slave camera is calculated according to the target region position, and the slave camera is rapidly controlled to acquire high definition detail information from the camera. The invention can efficiently determine the valuable target region in the monitor scene, continuously trace a motion target and realize multi-target dynamic continuous tracing.

Description

technical field [0001] The present invention mainly relates to an active video acquisition method and device based on binocular photography. Background technique [0002] The video surveillance system is an important part of the security field, widely used in the monitoring of party and government organs, military important places, traffic arteries, public places, residential houses and other places to prevent illegal acts such as sabotage, theft and trouble, and protect the people safety and social harmony. [0003] However, in the existing video monitoring system, usually only one camera is set up at the same observation point to collect video images with fixed resolution. This monitoring method has the following problems: (1) if the lens of the camera is at the wide-angle end, then What is collected is the global information of the scene under the observation point. Although the moving target in the scene can be accurately located and tracked at this time, because the nu...
