Video surveillance program
find_image_express
In the find_image_express program video processing in real time on the computer from cameras of security video surveillance is applied.
The program of video surveillance can write from cameras on the HDD avi video files when there is a movement in sight of cameras (the movement detector).
The find_image_express program works at a board of video capture of DVR HIKVISION DS-4004HCI. (4 video channels, each channel 25 frames / sec., PCI ).
In the program there is an image_plus.dll file which is responsible for image processing.
The maximum number of cameras - 4.
In the program there are settings on the movement detector.
It is possible to set up in the program:
1 . Contrast range of a moving body, contrast range of movement.
2 .Horizontal shift (in pixels). Vertical shift is the same. In the demonstration video in blue shows the shift and mark certain points. Tags other points other colors. If there is movement, there is an image of the body and the shift change. Shift settings are made for the filtration of various noises. For example trees and shrubs can not move away, but the man and the car can move away.
3 . The size of a moving body (intensity of movement, number of points in the amount).
4 . The degree of continuity of the special edge of the moving body (the number of pixels in the pixel group 6x20, 20x6 pixel is the same). The foliage of trees and shrubs do not have a clear continuous edge. Man and cars have a clear continuous edge.
5 . Sound on movement.
6 .The difference in frame rates (the interval between the two frames between which movement is checked (the difference between the frame (r) = ((n-th frame) - (n-r) th frame)) to check the movement and microshears (in pixels) of the frame difference.
7 . Interval of check of a difference of frames (in frames). The more often movement, the more loading of the processor is checked.
The supported and
recommended rotary PTZ chambers
for the find_image_express program are the Xpeed
CNB .
Here two models of the CNB chambers from the Xpeed type (see useful links) are shown
