Embodiment Construction

[0017] The implementation of the cloud computing system of the present invention will be described in detail below with reference to the accompanying drawings.

[0018] The artificial anti-sneak shooting method has inherent shortcomings. In order to overcome the above disadvantages, reduce the operating cost of anti-sneak shooting, and improve the work efficiency of anti-sneak shooting, the operator has been looking for an electronic anti-sneak shooting method for on-site monitoring. There are two developments for electronic anti-sneak shooting Direction, one is to make a fuss on the mobile terminal held by the audience, and automatically detect the sneak shooting behavior when the mobile terminal shoots, but this method may be circumvented because the sneak shooter chooses the mobile terminal. Electronic jamming equipment, this way can avoid the evasion of sneak photographers.

[0019] The existing anti-candid electronic interference equipment is to install an infrared device...

Abstract

The invention relates to a cloud computing system, which comprises audience face brightness detection equipment, projection room ambient brightness detection equipment and infrared laser equipment, wherein the infrared laser equipment is used for determining an own laser emission direction based on the output of the audience face brightness detection equipment and the output of the projection roomambient brightness detection equipment. According to the cloud computing system, the emission direction of a laser emission mechanism can be effectively controlled.

Description

technical field [0001] The invention relates to the field of cloud computing, in particular to a cloud computing system. Background technique [0002] In order to detect digital multimedia videos that are not authorized and illegally disseminated, watermarking technology has been widely studied and widely used. In the stage of film production or film projection, the method of embedding the "pattern" information in the film so that the human eye cannot see it can be adopted. If these films were secretly recorded by cameras, this embedded map can be extracted to identify the source of piracy. [0003] In order to identify and track pirated movies, some industry leaders have proposed anti-piracy through coding (CAP), which is to add watermarks to movies. The first coded anti-piracy was designed by Kodak and then improved by Deluxe Laboratories. Philips also proposed an identification system called CineFence in 2006. However, the watermarking technology is only a passive mea...
