A method and apparatus for automatically recording the number of viewers

Abstract

The invention discloses a method and a device for automatically recording the number of people watching movies. The method comprises the following steps: 1) installating and debugging an image acquisition device; wherein Among them, the acquisition equipment can modify the exposure parameters by software so that better image information can be acquired when the lighting of the cinema is turned onor off. After the equipment is installed, the large angle displacement cannot occur, so that the acquisition equipment cannot collect the complete image of the audience seat; 2) preprocessing that collected image; 3) carrying out standard image acquisition and record, comprising: acquire a standard image in an open field without a viewer playing a film normally for comparison with an image acquired in an actual situation in order to identify a viewer; 4) carrying out Actual image acquisition and recognition and counting of viewers, including: image acquisition before entrance of spectators: image acquisition is carried out before entrance of spectators in actual situation, the lighting is turned on standard, the lighting environment corresponding to step of standard image acquisition is guaranteed to be identical, and the collected image is compared with corresponding standard image, and so on.

Description

technical field [0001] The present invention relates to a device and method for automatically identifying and recording the number of viewers of a current session based on a movie playing in a theater. The present invention relates to image algorithms and image processing technologies, and to the fields of automatic control and display technologies. Background technique [0002] At present, when a movie is played in a movie theater, it is sometimes necessary to count the number of people and the box office accurately. However, the existing methods mostly rely on the movie tickets sold, and the number is not accurate. [0003] In addition, we all know that when a theater uses a 3D polarization system with three light paths or two light paths (such as Le-vision 3D polarization system) to play 3D movies, it can effectively increase the brightness of 3D movies without increasing the power of the projector. Greatly improve the viewing quality, so it has an extremely wide range of...

Similarly, the right lens of the glasses can only be passed by the left circularly polarized light output by the polarized liquid crystal light valve, while the right circularly polarized light output by the polarized liquid crystal light valve will cut off the left lens, so that the right eye can only see the projector The right-eye image is played, but the left-eye image cannot be seen
