No-reference network video quality evaluation method and device

The embodiment of the invention provides a non-reference network video quality evaluation method. The method comprises the following steps: acquiring a time point, a quantization step size and a resolution after each frame of video picture is decoded; obtaining a video fluency score based on the time point; obtaining a video definition score based on the quantization step size and the resolution; judging information of a service scene where the video picture is located; respectively endowing the video fluency score and the video definition score with corresponding weight values in combination with the business scene information; and obtaining a video quality score based on the video fluency score, the video definition score and the corresponding weight value. The video quality can be scored in combination with different use scenes by directly acquiring the decoding time, the video quantization step size and the resolution of each frame of decoded video picture. In addition, the embodiment of the invention pro
