Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is clearly and completely described, obviously, described embodiment is only the present invention's part embodiment, rather than whole embodiment.Based on the embodiment in the present invention, those of ordinary skills, not making under the creative work prerequisite the every other embodiment that obtains, belong to the scope of protection of the invention.
The embodiment of the invention discloses a kind of recognition methods of Quick Response Code based on Digital Television, set-top box and system, can, at the device that does not need to carry camera, not reduce information under the prerequisite of the concerned degree of digital television program, that the Quick Response Code that occurs on digital TV picture is pointed and be presented on video screen.Below be elaborated respectively.
Refer to Fig. 1, be an embodiment schematic flow sheet of the recognition methods of the Quick Response Code based on Digital Television of the present invention.As shown in Figure 1, the disclosed a kind of Quick Response Code recognition methods of the embodiment of the present invention can comprise the following steps:
S101, the position at Quick Response Code place in the picture of set-top box location.
In the embodiment of the present invention, set-top box is including but not limited to digital television bidirectional set-top box, Intelligent set top box, IPTV set-top box, OTT set-top box or be built in the set-top box in Digital Television, as in digital TV integrated machine etc. any one or multiple.In a kind of feasible execution mode, the position at Quick Response Code place in the picture of location specifically can comprise the following steps:
Set-top box is carried out the thresholding processing to picture, to convert this picture to black and white picture;
Set-top box is processed picture later to thresholding and is carried out the dilation operation processing, with the shape edges by picture, enlarges, and is convenient to detect the shape edges of picture;
Picture after set-top box is processed dilation operation carries out edge detection process, with the shape edges of location picture;
If in edge detection process, detect in picture, there is square area, the coordinate of this square area of set-top box recording, the position of this square area is the position at Quick Response Code place.
The content that it is pointed out that above-mentioned square area is Quick Response Code not necessarily, and this step is assumed to Quick Response Code by the content of all square area, by its tick lables out, waits until follow-up identification.
S102, the content of the position at set-top box identification described Quick Response Code place.
The content of the position at the Quick Response Code place of locating in set-top box identification step S101, whether the content of judging above-mentioned position is Quick Response Code.For instance, step S101 orients the position at two Quick Response Code places, and the content of one of them position is Quick Response Code, and the content of another position is other square pattern, this step is identified the content of these two positions successively, judges whether these two positions are Quick Response Codes.Wherein, the Quick Response Code recognition technology is prior art, at this, does not do and repeats.
S103, if identify Quick Response Code, set-top box is accessed the information that described Quick Response Code points to.
If in step S102, identify Quick Response Code, by the built-in browser of set-top box, access the information that this Quick Response Code points to.Particularly, the content of browser can show according to following two kinds of modes: browser is suspended on the current display frame of Digital Television in translucent mode; Perhaps the current display frame of Digital Television is dwindled and is embedded among described browser content.
In the embodiment of the present invention, location, identification and access process that set-top box can the complete independently Quick Response Code, do not need to carry the device of camera; By the information that Quick Response Code is pointed to, be presented on the display screen of Digital Television, thereby user's focus is locked on Digital Television, remain the concerned degree of digital television program.
