A method for automatic detection and calibration of movie projection quality

Abstract

The invention relates to a method for automatically detecting and calibrating film projection quality, comprising the following steps: a server obtains the start time and end time of the projection schedules of each projection hall; the server obtains the state of detection equipment and projection equipment and the next Start time, confirm whether the device is working normally; the server automatically calls the dedicated playlist, starts to play the test video, captures the real projected image information on the screen, and analyzes and marks the movie test video; Unqualified items, the server automatically calibrates uniformly. After the present invention intelligently and automatically imports the scheduling from the ticketing system, it can intelligently identify the working status of the detection equipment and the projection equipment, and automatically calculate whether the current time can be detected and adjusted; the degree of automation is high, and the user only needs to configure the detection settings once, and the server will It will automatically start detection and calibration tasks, which can well meet the needs of practical applications.

Description

Technical field[0001]The invention belongs to the technical field of movie projection, and specifically relates to a method for automatically detecting and calibrating the quality of movie projection.Background technique[0002]On March 24, 2016, the Film Bureau of the State Administration of Press, Publication, Radio, Film and Television issued a notice on strengthening the management of theater projection technology and improving the quality of film projection, requiring each theater to ensure the brightness, clarity, color temperature, uniformity, and flatness of the theater screen, and The acoustic performance and frequency response of the auditorium also meet the standard requirements. At present, most theaters do not have relevant testing equipment and technicians. A few theaters rely on the annual maintenance provided by the projector manufacturer to perform a calibration. The sound-returning equipment basically does not have daily calibration. Only occasionally calibration is ...

AI Technical Summary

Problems solved by technology

There are also some high-end theaters that have installed testing equipment for pre-screening testing, but their testing requires the installation of a dedicated system on site in addition to the testing equipment, and it can only be tested by someone who operates it every day, and it is only for testing and cannot provide calibration functions

The disadvantages of the above two methods are: 1. Most theaters do not have daily calibration, and only occasionally calibrate once in a while, so it is difficult to guarantee the projection quality

2. A small number of high-end theaters can only detect the projection quality, but cannot achieve automatic calibration. It is necessary to notify professionals to come to calibrate separately, and it is difficult to guarantee the projection quality during the period

3. A small number of testing theaters require specialized personnel to set up and operate, which is not easy to use
