Abstract

The invention provides a novel three-dimensional video coding quality evaluation method. The novel three-dimensional video coding quality evaluation method comprises the following steps: S1, encodingand testing a video, and obtaining three values of code rate / channel, quality, and complexity through different transmission conditions; S2, judging whether values of the code rate / channel and the complexity meet a condition or not; if so, entering to step S3; otherwise, discarding the set of coding parameters; S3, judging the video quality, sorting the quality values in an order from high to low,and selecting an optimal coding parameter combination through the quality value judgment or the judgment of the complexity value and the coding / channel value; and S4, obtaining the optimal parameteras the coding parameter. According to the novel three-dimensional video coding quality evaluation method provided by the invention, the optimal coding parameter combination is selected, so that a goodeffect of real-time coding transmission is obtained.

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 ...
