Abstract
The invention discloses the method that a kind of image comparison method detects operating state of cloud platform video camera.Obtain the image that a monopod video camera to be measured is taken, send a control command to monopod video camera to be measured then, after command execution finishes, obtain the image that a monopod video camera to be measured is taken again, relatively the difference of this two width of cloth image so circulates for several times.Abnormal monopod video camera sends warning to network management system or operator to working.Method algorithm of the present invention is simple, and is low to hardware requirement, can accomplish to lower the cost of system greatly in the embedded system, also improved the reliability and stability of system simultaneously.
Description
Technical field
The present invention relates to the Equipment Inspection of video monitoring system.Especially the automatic telemetering of the operating state of video monitoring system front-end camera and The Cloud Terrace thereof,
Background technology
In the known technology of field of video monitoring, do not see the method for simple possible automatic telemetering front end platform video camera operating state, generally be to control video camera and The Cloud Terrace with artificial mode, the operator judges according to the variation of the image passed back whether front-end camera and The Cloud Terrace be working properly, and the shortcoming of doing like this is to waste time and energy with human eye then.
Summary of the invention
The invention discloses a kind of method by image comparison method detection operating state of cloud platform video camera, the operating state of system's automatic telemetering front-end camera and The Cloud Terrace thereof, abnormal monopod video camera sends warning to network management system or operator to working.
Technical scheme of the present invention is, at first obtain the image that a monopod video camera to be measured is taken, send a control command to monopod video camera to be measured then, after command execution finishes, obtain the image that a monopod video camera to be measured is taken again, the difference of this two width of cloth image relatively then, so circulation for several times, if each difference is all little or do not have difference, then show the not execution of order of sending, have fault, software comes telemetry front end video camera and The Cloud Terrace in view of the above, and reports measurement telemetry.
Because method comparison of the present invention is the difference of two width of cloth rest images, and speed is a second level, algorithm is simple, requirement to hardware CPU is very low, the software and hardware that does not need professional video such as DSP to handle fully, can accomplish to lower the cost of system greatly in the embedded system, also improve the reliability and stability of system simultaneously.
Description of drawings
The present invention is further described below in conjunction with drawings and Examples.
Fig. 1 is a program flow chart
Embodiment
In Fig. 1, program detects monopod video camera by image comparison method.
Step 1: program begins, the initialization context variable.
Step 2: by vedio data collection/intercepting single-frame images data.
Step 3: by video image analysis, extract RGB three primary colors luminance component by the software bandpass filtering respectively, and the storage of the luminance component of the three primary colors that will gather, extract, as the reference value.
Step 4: switch camera pan-tilt motion detection item (comprise upwards, downwards, left, action to the right).
Step 5: judge whether this detection reaches detection number of times (it is 3 times that acquiescence detects number of times).Reach the detection number of times, turn back to and judge whether to detect the item that finishes, otherwise, Function detection entered.
Step 6:, extract RGB three primary colors luminance component by the software bandpass filtering respectively by video image analysis.
Step 7: comparison is extracted RGB three primary colors luminance component whether in threshold range is set, if change in threshold range, thinks that then image does not change, and this testing result The Cloud Terrace fault is set; If change, think that then this detects The Cloud Terrace and detects normal outside threshold range.
Step 8: after detecting three times, if judge that three motion images three primary colors luminance components all outside threshold range, then are judged as equipment fault, the Returning equipment fault; Otherwise think that Equipment Inspection is normal, proceed next motion detection.
Step 9: finish above everything successively and detect, all detect normally, think that camera is working properly, otherwise, think equipment fault.
Claims (1)
1, a kind of computer implemented method, it is characterized in that: at first obtain the image that a monopod video camera to be measured is taken, send a control command to monopod video camera to be measured then, after command execution finishes, obtain the image that a monopod video camera to be measured is taken again, the difference that compares this two width of cloth image then, so circulation for several times.
