Description
Technical field
The present invention relates to image processing field more particularly to a kind of key position bulge degree-measuring systems.
Background technology
Supermarket, that is, supermarket, generally refer to commodity open display, customer self choose, is lined up cash register clearing, with operation
Shop based on fresh food, various household supplies articles for use.A kind of self-service retailer for choosing, unifying cash register clearing of consumer.Super city
Field is generally sold based on food and daily necessities, and feature is mainly：(1) small profits and quick turnover are substantially divided into low during shop-assistant manages
Shelves commodity；(2) commodity use inner wrapping, indicate component, specification and price；(3) trolley or goods basket, customer's self-selection store are had；
(4) lump-sum settlement of going out is paid the bill.
The supermarket at initial stage is simultaneous to sell a small amount of groceries based on food；At present also be concurrently in charge of except above-mentioned points cosmetics, stationery,
Hardware, clothes etc., up to seven or eight thousand kinds develop to integrated service, add parking lot at present, coffee-house, club, cinema with
And the various service facilities such as bank, insurance, postal service, it have developed rapidly, many supermarket sales volumes have been more than department store.
Since supermarket check out counters have accumulated many cashes, especially at the moment in night, therefore, often become attacking for offender
Object is hit, although many supermarket check out counters are assembled with live picture pick-up device and are monitored, on the one hand, this monitoring is passive
, it is often more important that, after offender often destroys live picture pick-up device, just implementation criminal offence, and this feelings
Condition is difficult to be taken precautions against.
Invention content
To solve the above-mentioned problems, the present invention provides a kind of key position bulge degree-measuring systems, in super market checkout
The front of image capture device above platform introduces lamina of septum pellucidum, and based on each key position in human object subgraph
Bulge degree determines corresponding degree of danger, when degree of danger transfinites, to release the lamina of septum pellucidum of high protective capacities to image
Collecting device is protected, to avoid image capture device from being damaged.
According to an aspect of the present invention, a kind of key position bulge degree-measuring system is provided, the system comprises：
Image capture device is arranged in the top of supermarket check out counters, for carrying out figure to the scene near supermarket check out counters
As data acquisition, to obtain and export cashier scene image；
Telescopic support struts are arranged on described image collecting device, super for described image collecting device to be fixed on
At the roof of the top of city's cashier；
For the telescopic support struts in Elongation Mode, described image collecting device is located at the roof of the top of supermarket check out counters
Lower section；And the telescopic support struts, in collapsed mode, described image collecting device is retracted to the upper of supermarket check out counters
In the roof of side；
Lamina of septum pellucidum is located at the roof of the top of supermarket check out counters, is aluminum oxynitride material, is retracted under default conditions
In the roof of the top of supermarket check out counters, under non-default state, in a manner of the roof of parallel and supermarket check out counters top
It is pushed out in the roof of the top described image collecting device to be isolated to supermarket check out counters；
Drive control apparatus is located near described image collecting device, respectively with telescopic support struts and described transparent
Partition board connects, for when receiving strick precaution control signal, controlling the telescopic support struts and being switched to institute from the Elongation Mode
Collapsed mode is stated, and controls the lamina of septum pellucidum and is switched to the non-default state from the default conditions.
It can be seen that the present invention at least has following two important inventive points：
(1) pattern extraction is carried out to each key position in the human object subgraph, to obtain each key portion
Bit patterns determine corresponding bulge degree for each key position pattern, based on the pass there are bulge degree higher than limitation
The quantity of key position pattern determines corresponding classes of dangerous degree, to realize the degree of danger to personnel near supermarket check out counters
Targetedly judged；
(2) when degree of danger is excessively high, shrink picture pick-up device automatically, and be adopted as aluminum oxynitride material carry out camera shooting set
Standby lens protection, so as to keep the uninterrupted picture control to scene.
Specific implementation mode
The embodiment of the key position bulge degree-measuring system of the present invention will be described in detail below.
With the development of supermarket, there is quick rising in the turnover of supermarket, at present supermarket's also be concurrentlying in charge of except above-mentioned points
