Embodiment Construction
[0022] In the video monitoring method and video monitoring system of the present invention, the video monitoring method can calculate the vertical and horizontal offsets of the first video data relative to the second video data when the first video data and the second video data overlap , splicing the first video data and the second video data according to the vertical and horizontal offsets, so that the video data output by the first camera and the second camera are relatively complete and clear without overlapping video data , which is convenient for users to view; in addition, due to the wide coverage of multiple cameras, it can realize video monitoring in a large area.
[0023] The specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.
[0024] Video monitoring method of the present invention, as figure 1 , including the steps:
[0025] S101. Collect the first video data through the first camera, and...

The invention discloses a video monitoring method and a video monitoring system. The video monitoring method comprises the following steps: collecting first video data by a first camera and collecting second video data by a second camera; when the first video data are overlapped with the second video data, extracting first overlapped data and second overlapped data; converting the first overlapped data into a first grayscale and converting the second overlapped data into a second grayscale; utilizing a block matching function to calculate the matching position information of the pixels of thefirst grayscale in a first presumptive area and the pixels of the second grayscale in a second presumptive area by a per pixel comparative method; matching the first video data and the second video data according to the position information. The invention causes the video data output by the first camera and the second camera to be relatively integral and clear and has no overlapped video data.
Description
technical field [0001] The invention relates to the field of computer technology, in particular to a video monitoring method and a video monitoring system. Background technique [0002] In the prior art, monitoring a certain area is carried out by installing a camera for video monitoring; when a large area is to be monitored for video, multiple cameras need to be installed, and the video data output by multiple cameras may have Overlapping parts cause the video data with overlapping parts to be blurred, which affects the integrity and clarity of the output video data, making it very inconvenient to watch. Contents of the invention [0003] The invention provides a video monitoring method and a video monitoring system, which improve the integrity and clarity of video data output by multiple cameras. [0004] Technical scheme of the present invention is: a kind of video monitoring method, it comprises steps: [0005] Step 1, collect the first video data through the first c...
