Description

Smart machine cloud platform management system

Technical field

The present invention relates to cloud platform field, more particularly to a kind of smart machine cloud platform management system.

Background technology

Currently, there is the drawbacks of inherent in the artificial anti-mode taken on the sly：First, if auditorium area is larger, need to pacify Arrange many staff and carry out field monitor, it means that need substantial amounts of cost of labor；Secondly, staff's naked eyes scan Mode efficiency is low, and the mode of direct surveillance easily occurs to let off the person of taking on the sly of some corner locations because of burnout；Most Afterwards, the mode of setting staff brings discomfort to the spectators of normal viewing performance near spectators, have impact on their appreciations and drills The mood gone out.

As can be seen here, the artificial anti-mode taken on the sly has inborn deficiency, in order to overcome above-mentioned drawback, reduces and prevents what is taken on the sly Operation cost, the anti-operating efficiency taken on the sly is improved, operator always searches for the anti-mode taken on the sly of electronics and carries out on-site supervision, electricity Anti- take on the sly of son has two kinds of developing direction, and a kind of made an issue of on the mobile terminal held in spectators, when mobile terminal is shot certainly Dynamic detection is taken on the sly behavior, but this mode may be because that the person of taking on the sly is avoided to the selection of mobile terminal, another kind be The scene of taking on the sly disposes electronic jamming device, and this mode can avoid evading for the person of taking on the sly.

The existing anti-electronic jamming device taken on the sly is that a kind of infrared facility is placed in the back side of curtain or stage, Infrared facility sends the sightless infrared ray of human eye, infrared if the person of taking on the sly is moving terminal or video camera shooting Line will disturb the video camera imaging of the person of taking on the sly, the image or lower picture quality for causing the person of taking on the sly to obtain, can not commercially sell Sell and propagated on network, so as to effectively safeguard copyright interest.

But this mode needs to launch infrared ray always, and the transmitting of infrared ray is large-scale, it is necessary to from each Infrared ray is all launched in position, and cost is higher and poor feasibility.Therefore the anti-equipment of taking on the sly of the electronics at scene also needs to find others Break through direction.

Therefore, the present invention proposes a kind of anti-electronic equipment taken on the sly in new scene, can be by audience seat The behavioral value of spectators and determine to whether there is in audience seat the person of taking on the sly by the parameter extraction to site environment, and The position where the person of taking on the sly can be positioned in time, in order to take corresponding orientation warning measure, remind the person of taking on the sly to put Abandon the behavior of taking on the sly.

The content of the invention

The sub- equipment of binary conversion treatment, select sub- equipment and histogram distribution to detect sub- equipment with threshold value respectively and be connected, for connecing When receiving global threshold selection signal, for each pixel in gray level image, when gray value is more than or equal to number of threshold values According to when, by for pixel be arranged to white level pixel, when gray value is less than threshold data, by for pixel set It is set to black level pixel, and binary image corresponding to output gray level image；The sub- equipment of binary conversion treatment is additionally operable to connecing When receiving non-global threshold selection signal, for each pixel in gray level image, the upward distance of vertical direction is calculated The gray value of the pixel of its 3 pixels calculates vertical direction downwards apart from its 3 pixels as upper grey scale pixel value The gray value of pixel as lower grey scale pixel value, calculated level direction to the left apart from its 3 pixels pixel gray scale Value be used as left grey scale pixel value, calculated level direction to the right apart from its 3 pixels pixel gray value as right pixel Gray value, when upper grey scale pixel value and the absolute value of the difference of lower grey scale pixel value are less than or equal to threshold data and left grey scale pixel value When being less than or equal to threshold data with the absolute value of the difference of right grey scale pixel value, by for pixel be arranged to white level pixel Point, when upper grey scale pixel value and the absolute value of the difference of lower grey scale pixel value are more than threshold data or left grey scale pixel value and right pixel When the absolute value of the difference of gray value is more than threshold data, by for pixel be arranged to black level pixel, and output gray level Change binary image corresponding to image；

The sub- equipment of picture smooth treatment, it is connected with the sub- equipment of binary conversion treatment, for receiving binary image, for binary picture Each pixel as in, when more than half trip point in adjacent all pixels point be present, then by for pixel The gray value of point retains, otherwise, by for the gray value of pixel be arranged to white level pixel, and export binary image Corresponding smoothed image；

The sub- equipment of medium filtering, it is connected with the sub- equipment of image balance processing, for receiving smoothed image, to the pixel of smoothed image The gray value of point is analyzed to determine the distribution radius in each noise profile region, point based on each noise profile region Maximum in cloth radius determines to carry out the filtered pixel block size of medium filtering, using the filtered pixel block size of determination to flat Sliding image carries out median filter process to obtain filtering image；

Data merge equipment, positioned at high in the clouds, are connected with M high in the clouds application apparatus, for by each high in the clouds application apparatus The filtering image of the sub- equipment output of value filtering is spliced to obtain filtering integral image；

On-Screen Identification equipment, it is arranged in the Background control room in theatre, merging equipment with data is connected to obtain filtering integration map Picture, filtering integral image is matched to detect and be partitioned into filtering with the screen pattern of the various mobile terminals prestored Each screen subgraph in integral image, for each screen subgraph, for its position in integral image is filtered It is determined that seat corresponding to the screen subgraph being directed to is numbered；Wherein, for screen subgraph corresponding to seat numbering be to hold For screen subgraph corresponding to mobile terminal spectators where theatre seat number；

Wherein, infrared laser pen also includes receiver of remote-control sytem, and remote signal and laser are opened for receiving the laser sent distal end Close remote signal；

Wherein, the quantity of the pixel value pixel that the match is successful and the relation of content matching percentage are non-linear dependences；

Wherein, R channel weightings value value is that 0.298839, G channel weighting values value is 0.586811, channel B weighted value value For 0.114350；

The gray value of black level pixel is 0；

The gray value of white level pixel is 255.
