Embodiment

[0028] refer to figure 1 , image 3 and Figure 4 , the film projection quality detection method described in this embodiment, the method includes:

[0029] S1, the detection controller sends the SPL of the sample to be tested to the projection server;

[0030] S2. After receiving the sample SPL to be tested, the projection server notifies the projector to play any CPL short film in the SPL of the sample to be tested;

[0031] S3, when starting from the playing of the CPL clip, the acousto-optic detector collects the luminance data and the sound data of the CPL clip in the playback in real time, and returns the luminance data and the sound data to the detection controller in real time;

[0032] S4. The detection controller calculates and compares the collected data with the pre-stored data of the CPL short film, and adjusts the corresponding interface with the relevant equipment for showing the CPL short film segments according to the comparison result.

Abstract

The present invention discloses a film projection quality detection method, and relates to the data processing field. The method comprises: a detection controllers issues SPL of a sample to be tested to a projection server; after a projection server receives the SPL of a sample to be tested, the projection server informs a projector of playing any one CPL short movie in the SPL of the sample to be tested; when the CPL short movie starts to play, an acousto-optic detection instrument performs real-time collection the brightness data and sound data of the section of the CPL short movie on the air and perform real-time returning of the brightness data and the sound data to the detection controller; and the detection controller compares the collected data with the data of the CPL short movie stored in advance and regulates corresponding interfaces of related devices of projecting the CPL short movie according to a comparison result. The film projection quality detection method eliminates the timing sequence errors of the acousto-optic data detected by the acousto-optic detection instrument to ensure the validity of the test result, ensure that a movie theatre system is more automatic for the correction of the sound and the brightness of the projector and facilitate better projection quality of the movie theatre.

Description

technical field [0001] The invention relates to the field of data processing, in particular to a method for detecting film projection quality. Background technique [0002] At present, the projection quality detection system used in theaters first controls the projection server to play the detection sample through the detection controller, and then the detection controller notifies the acousto-optic detector to perform acousto-optic detection on the playback sample, and finally the data detected by the acousto-optic detector Real-time transmission to the detection controller. [0003] Due to the different response times of different servers and / or the different response times of the same server under different load conditions after the detection controller releases the detection sample, the projection server may not be able to play the sample immediately. Therefore, the sample playback There will be a certain error between the actual start time of the test and the start tim...
