Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention.

As used herein, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed, but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.
Reference throughout this specification to "one embodiment" or "another embodiment" means that a particular feature, structure, or characteristic described in connection with the embodiment is included in at least one embodiment of the present application. Thus, the appearances of the phrases "in one embodiment" or "in this embodiment" in various places throughout this specification are not necessarily all referring to the same embodiment. It should be noted that the embodiments and features of the embodiments may be combined with each other without conflict.
The two-dimensional code to be identified in the invention includes but is not limited to the following three types: 1. a two-dimensional code (DM) code as shown in fig. 1-a-1, 1-a-2 and 1-a-3, a structure of the DM code including a position detection pattern as shown in fig. 1-a-1 and 1-a-2 and a Data area as shown in fig. 1-a-3; 2. a two-dimensional (QR) code as shown in fig. 1-b, in summary, the symbol of the QR code is composed of the following parts: a quiet zone, a position detection pattern, a correction pattern (there is version without this part), a reference grid, version information, format information, and a data zone, wherein the number of black dots on the reference grid is referred to as the version number of the QR code, and the QR code has 40 versions, and the constituent parts of each version are slightly different; 3. the two-dimensional Code (Maxi Code) shown in fig. 1-c is a two-dimensional Code with a fixed size, a fixed data capacity and a fixed data arrangement order, and is composed of a position detection pattern, a direction correction pattern, a data area, a reservation module, and a dead zone. Unlike other two-dimensional codes, in which the shape of the smallest module is a hexagon, it will be understood by those skilled in the art that the position of the two-dimensional code can be determined by the position detection pattern of the two-dimensional code, information of the two-dimensional code is acquired by identifying the data area of the two-dimensional code, and different classes of two-dimensional codes have different data verification capabilities, for example, a DM code can be successfully identified when about 40% of the information is lost, and a QR code can be successfully identified when about 30% of the information is lost.
Based on the above information, the present invention provides a method for identifying a two-dimensional code, so that the two-dimensional code to be identified can be identified quickly and accurately at night or in a dark environment, which is described below with reference to several specific embodiments.
Fig. 2 is a schematic flow chart of a first embodiment of a method for identifying a two-dimensional code according to an embodiment of the present invention, where an execution main body of the present invention is a terminal device with a flash lamp and an image capture device, for example, an electronic device with an image capture function, such as a personal computer PC, a notebook, a tablet, a wearable product, an intelligent home appliance, and an intelligent robot, as shown in fig. 2, the method includes:
s1: and when the two-dimension code scanning mode is started, acquiring a flash lamp triggering instruction.
As will be understood by those skilled in the art, when a two-dimensional code needs to be scanned, the terminal device may start the two-dimensional code scanning mode by receiving an instruction input by a user, or start the two-dimensional code scanning mode by invoking other modules, so as to identify the two-dimensional code to be identified.
In this step, in the using process, a user can align a camera of the terminal device with the two-dimensional code to be recognized, and then obtain a flash lamp trigger instruction, where the flash lamp trigger instruction is used to trigger the flash lamp to be turned on and gradually turned off, and preferably, the terminal device controls the flash lamp to be instantly turned on according to the flash lamp trigger instruction and gradually turned off within 1 to 2 seconds, fig. 3 is a schematic diagram of the change of the flash lamp intensity with time in the two-dimensional code recognition method provided by the embodiment of the present invention, and fig. 3 is a schematic diagram of the change of the flash lamp intensity with time in the process of turning on the flash lamp to gradually turn off the flash lamp.
In the specific implementation of the scheme, the specific modes for acquiring the flash lamp trigger instruction at least include the following modes:
in the first mode, a flash trigger instruction input by a user is received, for example, a flash control selected by the user through a human-computer interaction interface is received, or a flash trigger instruction input by the user according to a preset screen trigger mode (for example, double-click, finger joint touch, stroke and the like) is received.
In the second mode, a flash lamp trigger instruction input by a user according to a preset key operation mode (for example, long-time pressing of a volume key and the like) is received.
In a third mode, the flash lamp trigger instruction may be generated according to a preset condition, for example, the flash lamp trigger instruction is generated when the acquisition device of the terminal device is positioned to the two-dimensional code through the position detection pattern of the two-dimensional code, and for example, the flash lamp trigger instruction is generated after the two-dimensional code scanning mode is started for 3 seconds.
S2: and in the process of lightening and gradually extinguishing the flash lamp, carrying out image acquisition on the two-dimension code to be identified, and acquiring at least two-dimension code images.
In this step, it should be understood that, in the process that the flash lamp is turned on and gradually turned off, the flash lamp irradiates the two-dimensional code, a light reflection spot, that is, a light reflection region, is formed on the two-dimensional code, the size of the light reflection region is maximized after the flash lamp is instantly turned on, the light reflection region gradually decreases in the process of gradually turning off, along with the change of the brightness of the flash lamp, the terminal controls its own image acquisition device, for example, the camera performs image acquisition on the two-dimensional code to be recognized, may perform image acquisition according to a preset acquisition frequency, may perform image acquisition according to a preset acquisition time point, may perform corresponding image acquisition according to a preset flash lamp brightness value, and the setting of the time interval should take into account the frame rate setting of the acquisition device itself.
Due to the irradiation of the flash lamp, the at least two collected two-dimensional code images have light reflecting areas with different degrees in the two-dimensional code areas, and the areas outside the light reflecting areas are non-light reflecting areas, so that the at least two collected two-dimensional code images all comprise the light reflecting areas and the non-light reflecting areas.
S3: and carrying out two-dimensional code recognition on the at least two-dimensional code images to obtain a recognition result.
In this step, the two-dimensional code recognition is performed on at least two-dimensional code images, so that a recognition result can be obtained, specifically, each two-dimensional code image can be subjected to the two-dimensional code recognition, a decoding result of any two-dimensional code image which can be recognized is obtained, and the decoding result is used as the recognition result.
Further, before decoding according to the two-dimensional code graph, whether the two-dimensional code graph is decoded or not needs to be confirmed according to the size of a light reflecting area in the two-dimensional code graph, if the size of the light reflecting area in the current two-dimensional code graph is larger than or equal to a preset value, it is determined that the two-dimensional code graph cannot be recognized, if the size of the light reflecting area in the current two-dimensional code graph is smaller than the preset value, the two-dimensional code graph is decoded, and then, if the decoding is successful, an identification result is obtained, and if the decoding is failed, it is determined that the current two-dimensional code graph cannot be recognized.
The two-dimensional code image can be identified when the information loss caused by the reflection area of any one of the at least two-dimensional code images does not exceed the information loss which can be overcome by the two-dimensional code to be identified, and then the non-reflection area in the two-dimensional code image is decoded to obtain an identification result.
The recognition result includes content or operation corresponding to the two-dimensional code to be recognized, for example: if the two-dimensional code is a two-dimensional code for payment, a payment page is obtained through recognition, so that a user can complete payment operation, if the two-dimensional code is a personal two-dimensional code of an application, friend addition operation can be performed through recognition, and if the two-dimensional code is a commodity two-dimensional code, commodity information and the like of the commodity can be acquired through recognition.
In the method for identifying a two-dimensional code provided by this embodiment, after a two-dimensional code scanning mode is started, a flash lamp trigger instruction is obtained, the flash lamp trigger instruction is used to trigger the flash lamp to be turned on and gradually turned off, and in the process that the flash lamp is turned on and gradually turned off, image acquisition is performed on a two-dimensional code to be identified, at least two-dimensional code images are obtained, two-dimensional code identification is performed on the at least two-dimensional code images, and an identification result is obtained, where the identification result includes content or operation corresponding to the two-dimensional code to be identified, in the present invention, at night or when ambient light is dark, the flash lamp is used to assist in identifying the two-dimensional code, at least two-dimensional code images are acquired in the process that the flash lamp is turned on and turned off, each two-dimensional code image has a reflective area with different sizes under the irradiation of a reflective lamp, the at least two, the influence of the light reflecting area caused by the light reflecting light spots on two-dimensional code identification can be automatically overcome, a user does not need to adjust the scanning angle and position for multiple times, the problem that in the prior art, convenience in two-dimensional code scanning is poor when light is weak at night or around is solved, and user experience is improved.
Fig. 4 is a flowchart illustrating a second embodiment of a method for identifying a two-dimensional code according to an embodiment of the present invention, as shown in fig. 4, this embodiment still includes steps S1 and S2 in the embodiment shown in fig. 2, and after step S2, this embodiment further includes:
s301: and traversing and identifying each two-dimensional code image in the at least two-dimensional code images.
In this step, the terminal device may simultaneously identify each two-dimensional code image, or may complete the identification of each two-dimensional code image in a random order or a preset order, specifically, first, the terminal device determines whether each two-dimensional code image can be decoded, for example, determines whether the size of the light reflection area is smaller than a preset value, decodes the two-dimensional code image if the size of the light reflection area is smaller than the preset value, otherwise, determines that the two-dimensional code image cannot be identified, and then decodes the two-dimensional code image determined to be decoded, obtains a decoding result, and uses the decoding result as an identification result.
S302: and if the first two-dimensional code image exists in the at least two-dimensional code images and can be identified, obtaining an identification result according to the first two-dimensional code image.
The first two-dimensional code image is a two-dimensional code image which can be identified from at least two-dimensional code images. In this step, if the first two-dimensional code can be recognized, the decoding result of the first two-dimensional code is used as the recognition result, and the recognition result is pushed to the user, and the recognition process is ended at the same time.
In the embodiment, the terminal device performs traversal identification on each two-dimensional code image in the at least two-dimensional code images, judges whether a first two-dimensional code image capable of being identified exists in the at least two-dimensional code images, if so, acquires an identification result according to the first two-dimensional code image, and performs traversal acquisition on the at least two-dimensional code images with different light reflecting areas to acquire the identification result, so that the two-dimensional code is quickly identified.
In a specific implementation manner, fig. 5 is a schematic flowchart of a third embodiment of a method for identifying a two-dimensional code according to an embodiment of the present invention, and as shown in fig. 5, the determining whether each two-dimensional code image in at least two-dimensional code images can be identified includes:
s401: and acquiring a two-dimensional code area and a light reflecting area of the two-dimensional code image.

Specifically, the detecting the light-reflecting region includes: in the two-dimensional code area, whether the gray value of each pixel is larger than a threshold value W is judged pixel by pixel (the gray value range of the pixels in the two-dimensional code area is 0-255, 255 is a white gray value, 0 is a black gray value, and W is 255 usually), if yes, the pixel is determined to be a reflective pixel, marking is carried out, after the whole two-dimensional code area is traversed, the number of the reflective pixels is counted, and the size of the reflective area can be obtained.
S402: it is determined whether the light reflecting area is less than a preset value.
In this step, a preset value is determined in advance according to the data verification capability of the two-dimensional codes of different categories, where the preset value may be a ratio of the light reflection region to the two-dimensional code region, or a pixel size of the light reflection region, and then the terminal device determines whether the light reflection region is smaller than the preset value by comparing the light reflection region determined in step S401 with the preset value.
S403: if the light reflecting area is smaller than the preset value, decoding the content of the two-dimensional code area to determine whether the two-dimensional code image can be identified.

It should be understood that the second two-dimensional code image obtained through the superposition processing will maximize the non-light reflection area and reduce the information loss caused by the light reflection area.
S305: and identifying the second two-dimensional code image to obtain an identification result.
And identifying the second two-dimensional code image obtained through superposition processing, namely decoding the two-dimensional code area in the second two-dimensional code image to obtain an identification result.
