Abstract

The present invention provides a novel three-dimensional video encoding quality evaluation method, comprising: S1, performing an encoding test on a section of video, and obtaining three values ​​of code rate / channel, quality, and complexity through different transmission conditions; S2, judging the code rate / Whether the value of the channel and complexity meets the conditions, and enter step S3 if the conditions are met; otherwise, discard the set of encoding parameters; S3, judge the video quality, and the quality values ​​are sorted in order from high to low, and the quality value is judged or compared with The judgment of the complexity value and the coding / channel value selects the optimal coding parameter combination; S4, obtaining the optimal parameter as the coding parameter. The new three-dimensional video coding quality evaluation method of the present invention selects a better combination of coding parameters to obtain a good effect of real-time coding and transmission.

Description

technical field

[0001] The invention belongs to the field of security monitoring, and in particular relates to a novel three-dimensional video coding quality evaluation method. Background technique

[0002] Since the three measurement indicators of video bit rate, quality and coding complexity are mutually restricted and affect each other, optimizing one of the indicators will often affect the performance of other indicators. In order to comprehensively evaluate the quality and efficiency of video coding, select a better parameter combination , to obtain a good effect of real-time encoding transmission. This paper adopts a three-dimensional joint evaluation method based on bit rate (bandwidth)-quality-complexity (R(B)-Q-C), and evaluates the combination effect of video parameters according to this method. Among them, R(B) is used to measure whether real-time transmission can be realized under different bandwidth conditions, C is used to measure whether real-time coding can ...
