Embodiment Construction
[0040] The present invention provides a film projection detection method, computer-readable medium and system for cinemas. In order to make the purpose, technical solutions and effects of the present invention clearer and more specific, the present invention is further described below in detail. It should be understood that the specific embodiments described herein are only used to explain the present invention, but not to limit the present invention.
[0041] The present invention provides a film screening detection method for a cinema, the method includes step 90, such as figure 1 As shown, the step 90 includes:
[0042] Step 91, pre-store the sound loudness threshold [S 1 ,S 2 ], the definition threshold p, and the gray threshold value [A, B], which are respectively used as reference values for detecting the sound loudness, definition and brightness of the film, and can flexibly pre-store the corresponding sound according to different films. Loudness Threshold [S 1 ,S...

The invention discloses a film screening detection method, a readable storage medium and a system for cinemas, wherein the method includes step 100 to acquire live sound information, live picture information and playing time of the playing film; step 200 is based on the If the sound information is inconsistent with the pre-stored sound information, the judgment result is that the film is displayed abnormally. If they are consistent, then the next step is performed; according to the inconsistency between the on-site screen information and the pre-stored screen information, the judgment result is that the film is abnormal. If If they are consistent, the next step is the next step; according to the inconsistency between the playback duration and the pre-stored playback duration, the judgment result indicates that the movie is displayed abnormally, and if they are consistent, it is normal. With the method, it can be judged whether the movie is being displayed normally according to the live sound information, the live picture information and the playing duration information of the live-played movie, which solves the problem of the problem of low-quality movies caused by collecting local information in the prior art. omissions or misjudgments.
Description
technical field [0001] The present invention relates to the field of digital movie playing methods, in particular to a movie playing detection method, a readable storage medium and a system for movie theaters. Background technique [0002] The cinema film detection methods of the prior art often perform film quality detection based on the subjective judgment of the inspectors on the live film or partial sampling of the film, and often fail to find low-quality films due to insufficient detection samples collected or human subjective errors. Or the theater does not play the specified movie, which causes the audience to experience poor movie viewing or the interests of the theater partners are not protected. The manual sampling method is troublesome and has low accuracy. [0003] Therefore, the existing technology still needs to be improved and developed. SUMMARY OF THE INVENTION [0004] In view of the above-mentioned deficiencies of the prior art, the object of the present...
