Specific embodiment
Currently, the manufacturer of many video cameras, by acquiring video recording and picture after manually building site environment and carrying out craft
The mode of statistics carries out the test of video camera, and this test takes time and effort during the test, has little effect, limited by weather,
And there is certain risk.For example, Field Force, which generally requires, spends half a day or so installation and commissioning equipment, acquisition element could be started
Material.However it is limited to the ability of people, the acquisition of material is relatively cumbersome, and the effective time of collected material is often very short.In addition,
The place of acquisition needs not stop to replace, and reinstalls commissioning device, and the process for resurveying material can consume many times, finally
It needs long time also to carry out material analysis, therefore the most important index analysis work of manual testing, only accounts for entire test
Work time-consuming sub-fraction, and most times are used in the installation and debugging and material collection of repeatability.
Present inventor searches out the mode to solve the above problems and specifically includes that carries out algorithm on some virtual platforms
The mode of video camera is poured into test again after the completion of test；Video is either imported by the storage card of camera unit or network interface
Stream, is then tested on camera unit.However inventor based on aforesaid way carry out video current test during,
Have found following problem:
One is the test on virtual platform can not represent the test of video camera for the mode of virtual platform test, by
Difference is certainly existed between different platform, often there is test result and expected results are inconsistent.In addition, due to virtual platform
Performance be often better than the performance of video camera machine, also result in test result and have differences.
The second is importing the mode of video flowing or network interface importing video flowing, inventor for storage card (such as SD card)
The serious runnability for influencing video camera itself of discovery meeting during the test, because if needing to import video from storage card
Stream, is converted into the data of yuv format, by taking 25 frame per second as an example, CPU is needed constantly to read data, 1920* from SD card
1080*25*8bit/s (40Mbps) can seriously affect the performance of CPU, to destroy the accuracy of test result.In addition, from net
The mode that mouth imports video flowing is destructive for cpu performance.
In view of the above problems, it studies for a long period of time exploration through present inventor, proposes following embodiments, pass through virtual Sensor
The mode of signal, can be on the basis of not changing video test equipment original operational performance, recycling test material, thus
Automatic test can be carried out to great amount of samples and video test equipment intelligence test is effectively reduced to save labour turnover
Cost of labor promotes test accuracy rate, and test result is made to have inheritance.Following will be combined with the drawings in the embodiments of the present invention,
Technical scheme in the embodiment of the invention is clearly and completely described, it is clear that described embodiment is the present invention one
Divide embodiment, instead of all the embodiments.The component of embodiments of the present invention, which are generally described and illustrated herein in the accompanying drawings can
To arrange and design with a variety of different configurations.
Therefore, the detailed description of the embodiment of the present invention provided in the accompanying drawings is not intended to limit below claimed
The scope of the present invention, but be merely representative of selected embodiment of the invention.Based on the embodiments of the present invention, this field is common
Technical staff's all other embodiment obtained without creative efforts belongs to the model that the present invention protects
It encloses.
It should also be noted that similar label and letter indicate similar terms in following attached drawing, therefore, once a certain Xiang Yi
It is defined in a attached drawing, does not then need that it is further defined and explained in subsequent attached drawing.
