Abstract
The utility model discloses a self-adaption variable resolution acquisition system and belongs to the field of information processing. Acquisition systems of different resolution effects can be selected by self-adaption according to different targets. The system comprises a central processing unit and a low resolution camera connected on the central processing unit, as well as at least one high resolution camera. The high resolution camera is connected with the central processing unit, and the pickup range of the high resolution camera falls within the pickup range of the low resolution camera. The central processing unit analyzes the position information of target information in the pickup range of low resolution, and finally sets the physical position, indicated by the position information, of an image acquisition window of the high resolution camera to realize clear pickup of a target object. The self-adaption variable resolution acquisition system can realize not only video monitoring in a large range, but also automatic clear monitoring of the target object, thus improving the efficiency of attaining useful information.
Description
Technical field
The utility model relates to a kind of image, Video Collection System, and specifically as required a kind of different adaptively selected acquisition system with different resolution effect camera of or target belongs to field of information processing.
Background technology
Along with the development of society, video monitoring is applied to growing field.The camera that used being of monitoring at present has fixed resolution, can produce the image of extensive area in order to satisfy as far as possible, the resolution of this type of camera is all lower, the displays image information that the video of its production can only blur mostly, in case need to understand the image information in required concrete zone, may can't obtain information because resolution is low, such as the video monitoring that traffic is measured, if only need understand the information of car plate, and the video information of using the current low resolution camera to obtain may can relatively be blured at the car plate place and cause obtaining the effective information of license plate number.If with the camera of high-resolution camera replacement low resolution, because resolution increases, its video data also will sharply increase, and not only can add processing speed of data, be unfavorable for the extraction of valid data, but also can increase the carrying cost of data.
The utility model content
The purpose of this utility model provides a kind of self-adapting changeable resolution acquisition system with regard to being to overcome above-mentioned the deficiencies in the prior art, this system increases high-resolution camera in traditional low resolution image pickup scope, automatically the IMAQ window of the regulating high-resolution camera object that aims at the mark is realized the high-resolution shooting to destination object.
Realize that the technical scheme that the utility model purpose adopts is: a kind of self-adapting changeable resolution acquisition system, comprise CPU and be connected low resolution camera on the CPU, low resolution camera is transferred to CPU with the video information of shooting, this system also comprises at least one high-resolution camera, high-resolution camera is connected with CPU, and the image pickup scope of high-resolution camera is in the image pickup scope of low resolution camera.
The camera lens of described high-resolution camera can be according to the target in the low resolution camera image pickup scope, the through image acquisition window object that aims at the mark.
Described CPU also comprises the video information receiver module, is used to receive the video information of low resolution camera transmission; The video information process module is used to handle the video information that low resolution camera is transmitted, and extracts required target information from this video information, and gives control module with this message transmission; Control module, the camera lens by target information adjusting high-resolution camera accurately is positioned destination object until the IMAQ window.
Described high-resolution camera can dynamically arrange its IMAQ window.
The utility model is simple in structure, aim at the destination object in low resolution shooting district by direct use high-resolution camera, perhaps by central processing unit for processing low-resolution video information, analyze destination object information, extract then target information is in positional information in the low resolution image pickup scope, control high-resolution camera IMAQ window position at last in the physical location of positional information indication, realize clear shooting destination object.The utility model can not only be realized video monitoring on a large scale, and can also realize automatic clear monitoring to destination object, has improved the efficient of obtaining useful information.
Description of drawings
Accompanying drawing is a system configuration schematic diagram of the present utility model.
Embodiment
Self-adapting changeable resolution acquisition system comprises CPU as shown in drawings, and CPU comprises the video information receiver module, is used to receive the video information of low resolution camera transmission; The video information process module is used to handle the video information that low resolution camera is transmitted, and extracts required target information from this video information, and gives control module with this message transmission; Control module is by the camera lens of target information adjusting high-resolution camera.This system also comprises camera and at least one high-resolution camera of a low resolution, low resolution camera is connected with the video information receiver module of CPU, high-resolution camera is connected with the control module of CPU, and the image pickup scope of high-resolution camera is in the image pickup scope of low resolution camera.
Low resolution camera is used to absorb large-scale video information, and this video information is transferred to CPU, the video information process module analysis goes out destination object information, extract then target information is in physical location information in the low resolution image pickup scope, control high-resolution camera IMAQ window and be positioned the residing physical location of target information according to this physical location information by control module at last, realization is known shooting with high-resolution to destination object ground, obtain the video information of required destination object effectively, thereby obtain large-scale low-resolution video information and local high-resolution video information targetedly, improved data processing efficiency.
