Code scanning method, code scanning device and mobile terminal

1. A code scanning method applied to a mobile terminal with a camera normally-on when the mobile terminal is in a power-on state, the method comprising:

capturing an image with the camera and identifying a captured target image;

when identifying that the target image has an image feature of a preset graphic identification code, acquiring a target graphic identification code in the target image;

decoding the target graphic identification code to obtain an access link corresponding to the target graphic identification code; and

running a target application corresponding to the access link and displaying an access interface corresponding to the access link;

wherein the access interface comprises a payment interface;

the step of capturing an image with the camera and identifying a captured target image, comprises: when a screen of the mobile terminal is in a screen-off state, capturing an image with the camera of the mobile terminal and identifying the captured target image;

the step of running a target application corresponding to the access link and displaying an access interface corresponding to the access link, comprises: lighting up the screen of the mobile terminal, running the target application corresponding to the access link and displaying the access interface corresponding to the access link;

after the step of lighting up the screen of the mobile terminal, running the target application corresponding to the access link and displaying the access interface corresponding to the access link, the method further comprises:

when an authorized payment operation is received, completing payment according to an input payment amount;

closing the target application and closing the screen of the mobile terminal.

2. The method according to claim 1 , wherein after the step of decoding the target graphic identification code to obtain an access link corresponding to the target graphic identification code, the method further comprises:

identifying whether the access link is a valid link;

when the access link is identified as a valid link, extracting key characters in the access link;

searching for an application corresponding to the key characters from a preset database, and determining the application corresponding to the key characters as the target application.

3. The method according to claim 1 , wherein the step of running a target application corresponding to the access link and displaying an access interface corresponding to the access link, comprises:

judging whether the mobile terminal is installed with the target application;

when determining that the mobile terminal is installed with the target application, running the target application installed on the mobile terminal, and displaying the access interface corresponding to the access link by the target application;

when determining that the mobile terminal is not installed with the target application, running an applet corresponding to the target application, and displaying the access interface corresponding to the access link by the applet.

4. A mobile terminal comprising: a processor, a memory, and a computer program stored on the memory and executable on the processor; wherein the computer program is executed by the processor to:

capture an image with a camera of the mobile terminal and identify a captured target image;

when identifying that the target image has an image feature of a preset graphic identification code, acquire a target graphic identification code in the target image;

decode the target graphic identification code to obtain an access link corresponding to the target graphic identification code; and

run a target application corresponding to the access link and display an access interface corresponding to the access link;

wherein the camera is normally-on when the mobile terminal is in a power-on state;

wherein the access interface comprises a payment interface;

the processor is used to:

when a screen of the mobile terminal is in a screen-off state, capture an image with the camera of the mobile terminal and identify the captured target image;

light up the screen of the mobile terminal, run the target application corresponding to the access link and display the access interface corresponding to the access link;

when an authorized payment operation is received, complete payment according to an input payment amount;

close the target application and close the screen of the mobile terminal.

5. The mobile terminal according to claim 4 , wherein the processor is used to:

identify whether the access link is a valid link;

extract key characters in the access link when the access link is identified as a valid link;

search for an application corresponding to the key characters from a preset database and determine the application corresponding to the key characters as the target application.

6. The mobile terminal according to claim 4 , wherein the processor is used to:

judge whether the mobile terminal is installed with the target application;

when determining that the mobile terminal is installed with the target application, run the target application installed on the mobile terminal and display the access interface corresponding to the access link by the target application;

when determining that the mobile terminal is not installed with the target application, run an applet corresponding to the target application and display the access interface corresponding to the access link by the applet.
