Problems solved by technology

[0002] The use of digital video surveillance equipment is now very popular, widely used in building monitoring and intersection and road monitoring, but the resolution of these videos is generally low, which leads to a common problem in the current application, that is, when the need When looking at the details of the related video, it is found that due to the low resolution of the video, many details are very blurred and cannot be distinguished even with the naked eye
[0003] In order to solve the above problems, there are also dome camera systems that can adjust the focus, but the current focus dome cameras are not high in timing and accuracy.

Embodiment approach

[0042] According to an embodiment of the present invention, the method for determining the framing adjustment information specifically includes:

[0043] B1, the continuous video image of the input low-resolution probe is directly stored in the database unit;

[0044] B2. Determine the adjustment value of the viewfinder range;

[0045] B3, judging whether the framing adjustment value exceeds the preset threshold value d1, said d1=the total number of pixels of the image*r, r=5%-10%; if not exceeded, this processing ends, otherwise turn to B4;

[0046] B4. Directly obtain the video image of the current high-resolution probe;

[0047] B5. Determine the location of the calculation viewfinder.

[0048] The calculation steps of the framing adjustment value in the above B2 are as follows:

[0049] B21. Obtain the current image in the input continuous video image, calculate the background image according to the following formula, and save it:

[0050] f ...

Abstract

The invention discloses an automatic focusing system for real-time balling machine tracking. A time point and an image framing position of a high-resolution video image to be acquired can be detected by performing auxiliary focusing processing on a low-resolution video, and an actual monitored target position of the time point is obtained by a motion trace forecasting unit so as to correct the image framing position, so that automatic focusing of a ball machine system is realized, and real-time adjustment can be carried out; the accuracy is high.

Description

technical field [0001] The invention relates to the field of video monitoring, in particular to an automatic focusing system for real-time tracking of a dome machine. Background technique [0002] The use of digital video surveillance equipment is now very popular, widely used in building monitoring and intersection and road monitoring, but the resolution of these videos is generally low, which leads to a common problem in the current application, that is, when the need When looking at the details of the related video, it is found that because of the low resolution of the video, many details are very blurred and cannot be distinguished even with the naked eye. [0003] In order to solve the above-mentioned problems, there are also dome camera systems that can adjust the focus, but the current focus dome cameras are not high in terms of timing and accuracy. Contents of the invention [0004] The purpose of the present invention is achieved through the following technical s...
