Description
Technical field
The present invention relates to information and technical field of image processing, more particularly to a kind of secondary screen cabinet equipment localization method.
Background technique
In substation's digital Construction and regulation model of integration progradation, the nothing of full voltage grade transformer substation is realized
People it is on duty with it is intelligent be primary goal that major grid company is most asked.The intellectually and automatically of substation needs system can
It is automatically positioned each device location information on secondary screen cabinet, is laid the foundation for subsequent management with risk assessment.Secondary device conduct
The pith that high-tension apparatus is monitored in substation, occupies highly important status in whole transformer station.It is set at present to secondary
Standby monitoring remains in such a way that electrical quantity is monitored equipment, but equipment operating condition, this equipment fault,
Under the influence of the factors such as third party device failure, secondary line, there are numerous difficulties for monitoring work.Substation secondary device quantity
More and interface is different, causes data collection capacity big, many kinds of, and the cost for individually developing data collection system is excessively high.Manually obtain
The mode for taking secondary device information is still mainly to solve problem mode, timeliness, accuracy existing for present substation summarizes
It is poor, low efficiency, it is most likely that cause failure that cannot be found that there are some potential safety problemss in time.Existing video monitoring letter
Acquisition system camera limited amount is ceased, and does not have positioning function, it is still desirable to manually read and record information, however it remains effect
The problems such as rate is low obviously cannot meet the requirements in intelligent substation development process.Current device data acquisition standard is not
One, data record and analysis mode are mixed and disorderly, so that monitoring personnel judges that there are certain obstacles for failure.Data are subsequent
The difficulty analyzed again is larger.
Summary of the invention
The present invention proposes the secondary screen cabinet equipment localization method based on projective iteration method.It is obtained first with substation field
Secondary screen cabinet picture the template of equipment picture positioned will be needed to extract, then template picture and need positioning device
Picture does projection operation, then calculates the correlation function between the projection matrix and template of source figure, finds the high position of the degree of correlation,
The coordinate points exactly navigated to.A kind of side of secondary screen cabinet equipment automatic positioning based on projective iteration method proposed by the present invention
Method, the image that can be obtained by video frequency monitoring system are automatically positioned the equipment such as air switch, signal lamp on secondary screen cabinet, from
And push the intelligence of substation secondary device information monitoring.
The technical scheme is that；A kind of secondary screen cabinet equipment localization method, includes the following steps；
S1: acquisition secondary screen cabinet message sample picture；
S2: the template graphics for needing the various types of LED lights and secondary screen cabinet panel-switch that identify are extracted；
S3: projection function of the calculation template for specific direction；
S4: the projection function of subgraph in the source figure to be operated is calculated；
S5: each template projection is calculated with FFT and projects correlation function with each subgraph；
S6: finding the maximum coordinate points of the degree of correlation, and judges whether to be greater than threshold value, is exactly phase in the figure of source if more than the then point
Answer the position of template.
Further, the specific direction projected in step S3 is to project along the y axis.
Further, the size of source figure is N*N, template M*M, the projection function of template are as follows:
Subgraph in the figure of source on the basis of a certain pixel is with this length for starting point be M column data；
The calculation method of the projection function of subgraph is as follows in the figure of source:
Further, as follows using FFT calculating correlation function calculation method in step S5:
Wherein
Further, the samples pictures in step S1 derive from the picture of substation secondary screen cabinet fixed angle shooting, shooting
Position is the opposite of secondary screen cabinet panel, and left-right deviation is 30 degree, and the range of upper lower deviation is 10 degree -70 degree.
The beneficial effects of the invention are as follows；The secondary screen cabinet equipment positioning based on projective iteration method that the invention proposes a kind of
Method.The secondary screen cabinet image information obtained by video monitoring system is automatically positioned secondary screen cabinet upper switch and indicator light etc.
Information largely improves the degree of the automation of transformation substations, can preferably carry out the management of secondary device information.Benefit
With method of the present invention may be implemented to substation secondary device location information it is real-time acquisition and monitoring, save manually at
This while, can be with raising efficiency, the available preferable application in intelligent substation development process.
