Detailed Description
The present invention provides a zxing-based continuous scanning method and a mobile terminal, and the following further describes the present invention in detail in order to make the purpose, technical scheme and effect of the present invention clearer and clearer. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
Zxing is an open source, 1D/2D barcode image processing library implemented in Java in a variety of formats, which contains ports for linking to other languages. Zxing can realize that the scanning and decoding of bar codes or two-dimensional codes can be finished by using a camera arranged in the mobile terminal.
Referring to fig. 1, fig. 1 is a flowchart illustrating a zxing-based continuous scanning method according to a preferred embodiment of the present invention. The embodiment of the invention is applied to the mobile terminal provided with the camera. As shown in fig. 1, it includes the steps of:
s100, calling a zxing scanning program, expanding zxing scanning frequency and acquiring a scanning mode of the mobile terminal;
step S200, when the mobile terminal is detected to be in a continuous scanning mode, controlling the camera to be in a scanning state all the time, and displaying a scanning interface on a display screen of the mobile terminal;
and step S300, acquiring scanned data, and displaying the scanned data and a scanning interface on a display screen of the mobile terminal together.
In specific implementation, the mobile terminal in the embodiment of the present invention is introduced by taking a mobile terminal installed with an android system as an example. The mobile terminal includes but is not limited to a smart terminal such as a mobile phone and a tablet computer. Take a mobile phone as an example for introduction. Zxing is selected as a camera bottom layer calling frame in the mobile phone in advance.
If the default camera configuration of zxing is used, it is found that it needs to be very close to the two-dimensional code to be recognized, but this causes a problem of difficulty in focusing. The solution is to adjust the camera preview magnification and reduce the time for the camera to focus. It has been found through testing that the maximum magnification of each handset is nearly different, which may be related to the model of the camera. If set to a fixed value, it may result in excessive amplification on some handsets and insufficient amplification on some handsets. The parameter setting of the camera provides the maximum magnification value for us. To achieve continuous scanning and improve the efficiency of continuous scanning, configuration changes are made to the frequency of calls in the underlying call camera class of zxing. And calling a zxing scanning program to expand the zxing scanning frequency. The problem of adaptation of the mobile phone is perfectly solved by taking the large factor value as the current amplification factor.
The handset can operate in a single scan or in a continuous scan. When the mobile phone works in continuous scanning, the camera is controlled to be in a scanning state all the time, thereby reducing the scanning time,
and controlling the scanned data and the scanning interface to be displayed on the display screen of the mobile terminal together, so that the user can check the scanning result conveniently.
Optionally, step S100 is preceded by:
and performing logic analysis on parameters of the mobile terminal in advance, generating zxing maximum scanning number according to a logic analysis result, exposing the maximum scanning number to a user, and receiving a user instruction to set the maximum scanning number.
In particular, zxing's underlying functional configuration interfaces are often exposed only to internal reformers and to callers of system interfaces. Such configurations tend to have limitations and are not easily modified. Once set in the bottom layer of zxing, all models are used, but different models often have different CPU and memory sizes, and different camera hardware is configured, so such a setting often cannot exert the maximum efficiency of the models, and for this reason, the maximum scan number can be obtained only by analyzing in combination with the models. And performing logic analysis by taking three parameters of the CPU, the memory and the camera as dimensions, thereby obtaining an optimal value, exposing the optimal value to a user in configuration options, and enabling the user to know the setting. When the user is authorized, the user can make a decision of increasing or decreasing the maximum scanning number according to the specific weather condition and various factors at that time, so that the conditions such as the outside world can be fully combined, and the fastest scanning rate is increased.
In the bottom implementation of zxing, because scanning is a time-consuming operation, and occupies a large amount of memory and CPU performance of the mobile phone, in order to improve the utilization rate of the CPU and the memory of the mobile phone, zxing is generally defaulted to set the maximum scanning number. The arrangement is mainly used for preventing the scanning interface from staying in a continuous scanning state under certain unknown special conditions, and at the moment, the continuous scanning occupies a large amount of CPU and memory and consumes a large amount of power supply. Of course, in some cases, since a certain release is necessary in consideration of a large amount of memory resources, such as a long-time calling of a camera, zxing limits the maximum number of scans. Because the scanning frequency is increased, and the camera is not repeatedly turned on and off in the scanning thread, the pressure on a CPU, a memory and power consumption is released to a certain extent, and the maximum scanning number of zxing can be increased.
Optionally, expanding the zxing scanning frequency in step S100 includes: acquiring parameters of the mobile terminal, and acquiring a default frequency value and a high frequency value of zxing scanning frequency according to the parameters of the mobile terminal; wherein the high frequency value is the scanning frequency of zxing in continuous scanning, and the default frequency value is the scanning frequency of zxing in single scanning.
In particular, the scanning frequency is configured to be a default scanning frequency and a scanning high frequency. The default scanning frequency is applied to single scanning, and in single scanning, due to one-time scanning, the default scanning frequency can meet the calling requirement, and meanwhile, the memory consumption can be reduced for the low scanning frequency. For continuous scanning, as data is continuously acquired from a scanning page, the scanning accuracy and the scanning speed can be improved only by high-frequency scanning. Therefore, when the user selects continuous scanning, high frequency setting is performed so as to satisfy the requirement of scanning.
The zxing bottom layer can select the best frequency value according to the models of the camera hardware and the CPU, and then the best frequency value is used as a default value. However, at this time, the default value still needs to be manually set because part of the customization machine cannot recognize the camera and the CPU for setting. The setting of the high frequency value is a dynamic process, and the increment value increment is added on the basis of the default value defaultRate, so as to form the high frequency value.
In the selection of frequency values, the CPU overhead is sacrificed appropriately for successive scans, while the memory overhead is mainly reduced for a single scan.
Optionally, obtaining a parameter of the mobile terminal, and obtaining a default frequency value and a high frequency value of the zxing scanning frequency according to the parameter of the mobile terminal includes:
and acquiring the equipment model of the mobile terminal, and acquiring a default frequency value and a high frequency value of the zxing scanning frequency according to the equipment model of the mobile terminal. Specifically, the parameter of the mobile phone is the device model, and since the configuration of the mobile phone can be obtained according to the device model, the zing scanning frequency can be obtained according to the device model of the mobile phone.
And the default frequency value and the high frequency value of the zxing scanning frequency are automatically generated according to the parameters of the mobile terminal or generated after receiving the user instruction setting.
In specific implementation, zxing bottom layer can select the best frequency value according to the models of the camera hardware and the CPU, so as to be used as a default value. However, at this time, the default value still needs to be manually set because part of the customization machine cannot recognize the camera and the CPU for setting.
Optionally, step S200 specifically includes: when the mobile terminal is detected to be in a continuous scanning mode, controlling to start a camera control thread;
controlling the camera to be set to a permanent loop call in the camera control routine;
and displaying the scanning interface on a display screen of the mobile terminal.
In particular, when the continuous scanning mode is started, the camera thread is started by using the thread. The thread does not end after one scanning call of the camera, but exists all the time, and the mobile phone always displays a scanning interface to show that the mobile phone is still in a scanning state at present. When one-time camera calling is finished and a scanning result is returned, the camera automatically enters the next scanning preparation work to prepare the next scanning.
The permanent circular call refers to a circular call, that is, when the scanning method is called, the scanning method also includes the call of the scanning method, so that the call is ensured to be continuous all the time. When the continuous scanning mode is switched to the single-pass scanning mode, the permanent loop is turned off by the flag.
Sleep () is called when the customer passes the Home key, which process loses the lock on the thread. Wake up through thread is performed when returning to a call.
When the client quits, for the android, the quitting is divided into two modes: an exit button and a physical exit key of the interface. Stop () is called to stop the thread, at which point the memory space is completely freed and the space is reclaimed.
The camera call is realized by utilizing a single sub-thread to realize the control of the camera, meanwhile, the communication with the main thread is also ensured, the change of an interface is controlled, and the frequent call of interface drive is also reduced. Therefore, the scanning efficiency is improved, and the consumption of the memory is saved.
Optionally, step S300 specifically includes: acquiring a scanning result, analyzing the scanning result and adding the scanning result to a data list;
and updating the scanned data according to the data list, and displaying the updated scanned data and the scanning interface on a display screen of the mobile terminal together.
Specifically, the scanning result comprises a bar code and a two-dimensional code, when the bar code and the two-dimensional code are not in accordance with the specification, a specific abnormal code is returned, and the main thread is prompted to scan the abnormal code, so that data statistics can be performed. And (4) continuing to call the camera for scanning, and directly continuing to call the camera for focusing, scanning and acquiring results without closing the thread or the camera actually. Data are transmitted to the main thread, the camera thread is in communication with the main thread substantially, the camera thread captures data through the opened camera, then the data are sent to the main thread, the main thread acquires the data to display the data, the camera thread continues to scan, the efficiency of scanning can be guaranteed to be improved by concurrent operation, and the design initiatives of an android system are met.
And updating data by the Adapter corresponding to the RecycleView. When new data is added, the corresponding list is updated. In order to facilitate the user to view the data, the data display and the scanning are placed on the same interface, which requires that if the interface is displayed for the first time, the display of a data display page is needed, and if the interface is not displayed for the first time, only the data update and display are needed.
Thus, the interval time of continuous scanning is relatively short, and the scanning speed of the user is improved. The generation of the scanning result comprises the identification and the analysis of the two-dimensional code, when the identification is wrong, the specific error _ code 1XX and the specific error _ msg which are 'two-dimensional code/bar code can not be identified' are returned to be processed by the main thread, and the processing is exposed to a user, and the user-defined information prompt can be carried out on the error _ code 1 XX. Meanwhile, for the two-dimension code or bar code analysis exception, specific error _ code which is 3XX and error _ msg which is 'two-dimension code/bar code cannot be analyzed' are returned and are handed to the main thread for processing. The user can carry out specific prompt language prompt according to the service scene. When the two-dimensional code is identified and analyzed without problems, 2XX is returned, and at the moment, the information of the analyzed two-dimensional code/bar code can be obtained. For the android system, this information is passed to the main thread, which processes it. At this time, if the interface is not exited, a perpetual loop is entered, and the camera is continuously called to perform scanning identification.
The data adding comprises the acquisition of data and the adding of data. First, data is acquired, and since data is transmitted from the child thread to the main thread by inter-thread communication, the main thread also receives data. In this process, a Handler mechanism is involved, which is mainly related to four main parts. Namely, Handler, Looper, Message and MessageQueue. The Handler receives and processes. When data is sent to the main thread as a Message, the main thread is provided with a Message queue (Message Q ue), the Message is added, and the messages are sorted by a first-in first-out queue according to the time of the messages. Then a timing passer Looper performs a traversal in a certain time period. The message content is taken. Therefore, the continuous sending and the continuous obtaining of the messages are realized. The four generated relationships: looper is responsible for creating a MessageQueue and then entering an endless loop to read from the MessageQueue on a continuous basis. The creator of the Message is one or more of handle.
Before the Handler can be used, it needs to initialize an instance for updating the UI thread. And initialization is often either directly at declaration time or initializing the Handler instance in onCreate. The construction method of the Handler acquires the Looper instance stored in the current thread, and further associates the Looper instance with the MessageQueue in the Looper instance.
Secondly, data is added, because in android, a List control is used for presentation, and for the List control recycleview, an Adapter is needed, and the Adapter corresponds to a data set List in the List, so that a result of each scanning needs to be placed in the List.
Preferably, the update data includes two cases: first, there is existing data in the Adapter, and the data is also shown in the page. For this case, after adding data, only the notifydatasetcandied () method needs to be called, which can guarantee page refresh. And secondly, another situation is that no data page is displayed, at this time, data addition is needed, and meanwhile, a setAdapter () method of RecyclerView is called to add the adapter and pull up the page for displaying the data. And finishing the addition of the data and the display of the interface.
The zxing scanning algorithm comprises a global histogram binarization scanning algorithm and a mixed binarization scanning algorithm, and the method also comprises the following steps before calling the zxing scanning program:
and acquiring operating system parameters of the mobile terminal, and selecting a global histogram binarization scanning algorithm and a mixed binarization scanning algorithm according to the system parameters of the mobile terminal.
In the specific implementation, the graphic code image algorithm is selected, the graphic code scanning precision is related to a plurality of factors, and the most critical factor is the scanning algorithm. The graphic code comprises a bar code and a two-dimensional code. At present, in the field of pattern recognition, two more common two-dimensional code recognition algorithms are mainly used, wherein the two more common two-dimensional code recognition algorithms comprise: the global histogram binarization scanning GlobalhistogrammBinarizer algorithm is suitable for low-end equipment and has low requirements on a CPU and a memory of a mobile phone. But it selects all black dots to compute and therefore cannot handle both shadow and fade cases. The hybrid binary scan hybrid binary divider algorithm is slower in execution efficiency than the globalprost binary divider algorithm, but relatively more efficient in identification, and therefore suitable for high-end devices. The method is specially designed for analyzing the continuous black block two-dimensional code image with white as the background, and is also more suitable for analyzing the two-dimensional code image with serious shadow and gradual change. In the zxing calling, the system version and the system configuration of the mobile phone are firstly obtained; the high-low end is set with a critical value as the basis for selecting the algorithm.
