Embodiment 1
[0026] The self-adaptive video diagnosis device of Embodiment 1 includes: a diagnostic item algorithm module and a correction module, please refer to figure 2 . The use and operation of the device includes the following steps, please refer to image 3 :
[0027] Step 11, the diagnosis item algorithm module calculates the diagnosis item result A of the video image currently output by the front-end camera according to the diagnosis item algorithm.
[0028] The video diagnosis server can obtain video image data from the front-end camera according to the diagnosis plan, and then use the diagnosis item algorithm to diagnose each video diagnosis item according to the obtained video image data. Each diagnostic item may include image brightness, sharpness, color, etc. In the prior art, there may be various diagnostic item algorithms for different diagnostic items, and the present invention has no limitation on which algorithm is used to calculate the diagnostic items. The followi...
Embodiment 2
[0036] In most cases, before obtaining the diagnostic item result A of the current video image, the video diagnostic server has already diagnosed the diagnostic item results of several video images, and these results are used for statistical calculation to obtain the diagnostic item B of the diagnostic item. Embodiment 1 belongs to this case. But when the system is just started, there is no above result B. For example, the video diagnosis server starts to perform 24-hour video diagnosis at zero o'clock on Monday, Wednesday and Friday every week, and there are not n video images in the first few minutes of performing video diagnosis every Monday, Wednesday and Friday. The statistical result B of the corresponding diagnosis item; only after running for a period of time, can the calculation of the result B be performed according to the corresponding diagnosis items of the currently obtained n video images. In the initial period of time, how to correct the result A of the diagnos...
