Problems solved by technology
However, the existing video surveillance systems usually only record video images. When users look up historical data to find the information they need, they often need to view a large number of meaningless videos, which wastes time and is inefficient.
For example: in the process of detecting a criminal case, the user needs to consult a large number of video surveillance videos to find a moving suspicious vehicle. Significant videos, such as: pictures without vehicle information or pictures in a static state, etc., therefore, consume a lot of manpower and time, not only easily delay the time to solve the case, but also easy to miss due to fatigue caused by watching meaningless videos for a long time Target

Embodiment Construction
[0023] In order to describe the technical content, structural features, achieved goals and effects of the present invention in detail, the following will be described in detail in conjunction with the embodiments and accompanying drawings.
[0024] figure 1 Shown is a flow chart of an embodiment of the video playback method based on video analysis in the present invention. The user accesses the video recording to play the video according to the pre-set conditions. The steps of the video playback method based on video analysis include:
[0025] Step S11, decode the received video images and restore them to an image sequence. Wherein, the restored image sequence is generally a digital image sequence arranged in sequence.
[0026] Step S12, analyzing the image sequence frame by frame, filtering the image sequence that does not meet the preset conditions, and changing the playback rate of the video image.
[0027] Step S13, displaying the filtered image. In the embodiment of ...

The invention relates to a video playing method based on the video analysis, and the method comprises steps of decoding a received video image and restoring the received image to an image sequence; analyzing the image sequence frame by frame, filtering the image sequence which cannot meet a preset condition, and changing the playing speed of the video image; and displaying the filtered image. The playing speed of the video image is changed through the previously set filtering condition, a time period which cannot meet the condition in the video is automatically fast-forwarded or neglected, so that users can be helped to more quickly find the video segment when calling a video monitoring image, time can be saved, and the efficiency can be improved. In addition, the invention also provides a video playing system based on the video analysis.
Description
technical field [0001] The invention relates to video intelligent analysis and multimedia technology, in particular to a video playing method and system based on video analysis. Background technique [0002] In recent years, with the rapid growth of the national economy, the rapid progress of society and the continuous enhancement of national strength, the demand for safety precautions and on-site recording and alarm systems in the fields of banking, electric power, transportation, security inspection and military facilities is increasing day by day, and the requirements are getting higher and higher. , Video surveillance has been widely used in all aspects of production and life. However, the existing video surveillance systems usually only record video images. When users look up historical data to find the information they need, they often need to view a large number of meaningless videos, which wastes time and is inefficient. For example: in the process of detecting a cr...
