Detailed Description
In order to make the objects, technical solutions and advantages of the present invention clearer, the present invention will be described in further detail with reference to the accompanying drawings, and it is apparent that the described embodiments are only a part of the embodiments of the present invention, not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
In order to solve the problems that the existing mobile terminal can only carry out two-dimension code identification by installing a third-party application client integrating a two-dimension code function and the process of identifying a two-dimension code picture is complicated, the embodiment of the invention provides a two-dimension code picture identification method, which has the main ideas that: the camera application or the gallery application of the mobile terminal starts a second thread through the first thread, and the embedded two-dimensional code decoding service module is called through the second thread to decode the currently acquired picture.
In the following embodiments, a picture application is defined as a camera application or a gallery application in a mobile terminal.
In the embodiment of the present invention, as shown in fig. 1, the process of two-dimensional code image recognition specifically includes the following steps:
step 101: after the picture application acquires a picture through the first thread, starting a second thread, and calling a two-dimensional code decoding service module embedded in the picture application through the second thread to decode the picture through the second thread, wherein the picture application is a camera application or a gallery application in the mobile terminal.
In specific implementation, after a picture application acquires a picture through a first thread, if a trigger event for performing two-dimensional code decoding on the picture is monitored through the first thread, a second thread is started, and a two-dimensional code decoding service module embedded in the picture application is called through the second thread to perform two-dimensional code decoding on the picture.
Or after the picture application acquires the picture through the first thread every time, starting a second thread, and calling a two-dimensional code decoding service module embedded in the picture application through the second thread to decode the two-dimensional code of the acquired picture.
The trigger event for decoding the two-dimensional code of the picture may be a predetermined specific operation, for example, an operation of pressing a screen for a long time.
Specifically, if the picture application is a camera application, the camera application starts a second thread after obtaining a picture in a preview mode through the first thread every time, and calls a two-dimensional code decoding service module embedded in the camera application through the second thread to perform two-dimensional code decoding on the obtained picture.
Specifically, if the picture application is a gallery application, the gallery application starts a second thread after the picture displayed is switched by the first thread every time, and calls a two-dimensional code decoding service module embedded in the gallery application through the second thread to perform two-dimensional code decoding on the switched picture. Or the gallery application switches and displays the next picture through the first thread, if the operation of pressing the screen for a long time is detected through the first thread, the second thread is started, the two-dimensional code decoding service module embedded in the gallery application through the second thread performs two-dimensional code decoding on the currently displayed picture data, and otherwise, the second thread is not started.
Step 102: and the picture application acquires a two-dimensional code decoding result returned by the second thread through the first thread, and prompts a user to have the two-dimensional code information on a display interface if the two-dimensional code decoding result is determined to contain the two-dimensional code information.
In implementation, the picture application displays the two-dimensional code information after detecting an instruction for viewing the two-dimensional code information through the first thread. For example, if the two-dimensional code information is a webpage address, a webpage is opened according to the webpage address; and if the two-dimension code information is the contact information, displaying the contact information and the like.
For example, as shown in fig. 2, in the two-dimensional code image recognition process provided by the embodiment of the present invention, after the mobile terminal opens the camera application, the camera application starts a second thread every time a frame of image is obtained in the preview mode through the first thread, and calls the two-dimensional code decoding service module embedded in the camera application through the second thread to perform two-dimensional code decoding on the image. Or after the mobile terminal opens the gallery application, the gallery application starts a second thread every time the gallery application displays the next picture through the first thread in a switching mode, and the two-dimensional code decoding service module is called through the second thread to decode the two-dimensional code picture.

step 305: the camera application judges whether the two-dimensional code decoding result contains two-dimensional code information through the first thread, if so, the step 306 is carried out, and if not, the step 303 is carried out to obtain a preview picture again;
