Description
Technical field
The present invention relates to video technique field, in particular to a kind of novel video acquisition method.
Background technique
In traditional monitoring trade, the display data of video are only acquired, can reach the demand of display real-time pictures, and
Some emerging fields of today, such as: recognition of face, fire monitoring field only show that real-time video is unable to meet demand,
While showing video, algorithm will also analyze video data, be handled, and the processing that display data can increase algorithm is difficult
Degree, reduces the sensitivity of algorithm, at this moment just needs a kind of new video capture method.
Summary of the invention
In view of this, providing a kind of novel video acquisition method the purpose of the present invention is overcoming defect in the prior art.
Novel video acquisition method of the invention, comprising the following steps:
S1. video data is acquired using video capture device;
S2. the display data of the frequency acquisition equipment acquisition fixed pixel point;
S3. the initial data of the frequency acquisition equipment acquisition same pixel point;
S4. the initial data of acquisition and display data are shown respectively.
Further, in each frame image, for the display data distribution on the left side, initial data is distributed in the right.
Further, the display data and initial data are homologous.
Further, each frame image will acquire the initial data of video, and initial data is distributed in the right side in same frame.
Further, the display data of acquisition are used to show, initial data is for algorithm process.
Further, before acquiring video, the parameter of video collector should first be set.
The invention also discloses a kind of methods for carrying out video acquisition using the acquisition method, comprising:
Video source;
The data of video collector, acquisition have Visual Display Data and video original data;
Parameter configuration device;
Video acquisition driving, for receive with it is data cached;
Processor;
Display for receiving the display data of processor sending, and is shown;
Algorithm processor, for receiving the initial data of processor sending.
System according to claim 7, it is characterised in that: the parameter configuration device and video acquisition driving are respectively positioned on
In processor.
The beneficial effects of the present invention are: novel video acquisition method of the invention, on the basis of video is normally shown, drop
Low algorithm process difficulty, enhances the sensitivity of algorithm.
Detailed description of the invention
The invention will be further described with reference to the accompanying drawings and examples:
Fig. 1 is course of work schematic diagram of the present invention;
Fig. 2 is pixel map of the invention.
Specific embodiment
As shown in Figure 1, the present invention provides a kind of novel video acquisition method, including video source 1, video collector 2, parameter
Configurator 3, video acquisition drive 4, processor 5, display 6, algorithm processor 7, and parameter configuration device and video acquisition drive position
In processor.
The data that video collector 2 acquires have Visual Display Data and video original data, show data and original number
According to being homologous.The data collector parameter pre-configured according to parameter configuration device, every row first acquire the display number of y pixel
According to then the initial data of acquisition y pixel, i.e., every row pixel are z, and effective pixel points 2y, preceding y pixel is display number
According to, it is and then initial data pixel y, is finally left the inactive pixels that p is filling, in each frame, display data distribution
On the left side, initial data is distributed in the right, vaild act x in every frame, i.e., every frame effective pixel points are 2y*x, as shown in Figure 2.
Video acquisition driving 4, which is used to receive, will show that data are sent with data cached, 5 output data of processor, processor 5
To display 6, to be shown, initial data is sent to algorithm processor 7, is analyzed for algorithm, processing.
Finally, it is stated that the above examples are only used to illustrate the technical scheme of the present invention and are not limiting, although referring to compared with
Good embodiment describes the invention in detail, those skilled in the art should understand that, it can be to skill of the invention
Art scheme is modified or replaced equivalently, and without departing from the objective and range of technical solution of the present invention, should all be covered at this
In the scope of the claims of invention.
