 Invention embodiment

 Embodiments of the invention

[0026] In order to make the objects, technical solutions, and advantages of the present invention more clear, the following drawings and embodiments The present invention will be further described in detail. It is understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

[0027] Referring to FIG. 1, FIG. 1 is a flow chart of an embodiment of a method for scanning a two-dimensional code according to the present invention. The present embodiment is described from the perspective of a terminal, and the execution subject may be a terminal having a function of scanning a two-dimensional code, and the terminal may be a terminal such as a mobile phone or a tablet computer, but is not limited thereto. The method for scanning a two-dimensional code as shown in FIG. 1 specifically includes the following steps:

 [0028] S101: When the triggering operation of scanning the two-dimensional code is detected, the illuminance value of the ambient light is collected.

 [0029] When the terminal user needs to scan the two-dimensional code, the function of scanning the two-dimensional code is started through the interactive interface, so that the two-dimensional code scanning area corresponding to the terminal is aligned with the display area of the two-dimensional code to be identified.

 [0030] When detecting, by the terminal, an instruction to enable the function of scanning the two-dimensional code, or monitoring an operation of scanning the two-dimensional code through the scanning area of the two-dimensional code, the terminal collects the illuminance value of the ambient light in the current environment through the environmental sensor built in the terminal. . The current environment is the environment in which the terminal is currently located. The environmental sensor can be a light sensor or other sensor capable of collecting ambient light, and is not limited herein.

 [0031] The environmental sensor can obtain the illuminance value of the light by directly measuring the ambient light, and the unit of the illuminance value passes through the lux. In practical applications, the terminal system development kit provides two callback interfaces for use by the developer to pass the sensor's accuracy information and sensor-sensed data. Since the terminal may have a variety of sensors built in, the accuracy of each sensor is different, so when the accuracy changes, the interface of the sensor's accuracy change is called. The data sensed by the sensor includes: the accuracy of the data, the data monitored by the sensor, and the timestamp generated by the data.

 [0032] S102: Determine whether the illuminance value is less than a preset illuminance threshold.

 [0033] When acquiring the illuminance value of the current ambient light, the terminal compares the obtained illuminance value with the preset illuminance threshold, and determines whether the obtained illuminance value is less than a preset illuminance threshold.

 [0034] The preset illuminance threshold may be 0.3~llux, but is not limited thereto, and the preset illuminance threshold may be other values, which may be set according to actual conditions, and is not limited herein.

[0035] The terminal determines that the acquired illuminance value is less than the preset illuminance threshold 吋, and recognizes that the current ambient light is dark or insufficient light, and needs to turn on the flash to scan the two-dimensional code, and step S103 is performed; the terminal determines the obtained illuminance value. If the preset illuminance threshold is greater than or equal to 预设, no processing is performed, and the two-dimensional code to be identified is directly scanned. [0036] S103: When the illuminance value is less than the preset illuminance threshold, turn on the flash and scan the target two-dimensional code to be recognized.

 [0037] After determining that the acquired illuminance value is less than the preset illuminance threshold 吋, the terminal turns on the flash to illuminate by the flash, and increases the illuminance value of the current environment, so that the target two-dimensional code to be identified is in a sufficient light environment. . When the flash is turned on, the terminal scans the two-dimensional code of the target to be identified in the scanning range, and the terminal acquires the two-dimensional code of the target to be identified within the scanning range.

 [0038] In the above solution, when detecting the triggering operation of scanning the two-dimensional code, the terminal collects the illuminance value of the ambient light; determines whether the illuminance value is less than a preset illuminance threshold; and when the illuminance value is less than the preset illuminance Threshold, turn on the flash and scan the target QR code, which can automatically turn on the flash according to the ambient light illuminance value, saving the time for manually turning on the lighting device, and successfully scanning the QR code in the dark environment to improve the light. The efficiency of scanning the two-dimensional code in a darker situation, since the target two-dimensional code is in a well-lit environment after the flash is turned on, the situation of repeatedly scanning the two-dimensional code can be avoided, and the success rate of scanning the two-dimensional code can be improved.

 Referring to FIG. 2, FIG. 2 is a flow chart of another embodiment of a method for scanning a two-dimensional code according to the present invention. The present embodiment is described from the perspective of the terminal. The execution subject may be a terminal having a function of scanning a two-dimensional code, and the terminal may be a terminal such as a mobile phone or a tablet computer, but is not limited thereto.

 [0040] S201: Set an operation authority for controlling the flash.

 [0041] The terminal can be configured in the configuration file to set the operation permission of the control flash through the IHardwareService class or the camera Camera class.

 [0042] Among them, the IHardwareService class has a method of turning on the flash, and the developer can control the flash by simply inputting a parameter that is turned on or off in the method.

 [0043] In the terminal of the Android operating system, the operation permission of the flash is controlled by the IHardwareService class setting, and need to be added in the configuration file; mandroid.permission.HARDWARE_TEST permission. After the terminal user installs the application with the scanned QR code, if the permission to turn on the flash is not allowed, the terminal will enable the scanning QR code function, and when the control is turned on, the terminal will ask the user whether to allow access to the flash through the prompt box. The flash can only be turned on if the user allows it.

[0044] The Camera class comes with a rich interface and Parameters, which are mainly used for camera functions and are easy to expand. In When the operation of the flash is controlled by the _Camera class in the terminal of the Android operating system, you need to add the android.permission.CAMERA permission to the configuration file.

 [0045] S202: When the triggering operation of scanning the two-dimensional code is detected, the illuminance value of the ambient light is collected.

 [0046] When the terminal user needs to scan the two-dimensional code, the function of scanning the two-dimensional code is started through the interactive interface, so that the two-dimensional code scanning area corresponding to the terminal is aligned with the display area of the two-dimensional code to be identified.

 [0047] when detecting, by the terminal, an instruction to enable the user to scan the two-dimensional code function, or monitoring an operation of scanning the two-dimensional code through the two-dimensional code scanning area, the terminal collects the illuminance value of the ambient light in the current environment through the environmental sensor built in the terminal. . The current environment is the environment in which the terminal is currently located. The environmental sensor can be a light sensor or other sensor capable of collecting ambient light, and is not limited herein.

 [0048] The environmental sensor can obtain the illuminance value of the light by directly measuring the ambient light, and the unit of the illuminance value passes through the lux. In practical applications, the terminal system development kit provides two callback interfaces for use by the developer to pass the sensor's accuracy information and sensor-sensed data. Since the terminal may have a variety of sensors built in, the accuracy of each sensor is different, so when the accuracy changes, the interface of the sensor's accuracy change is called. The data sensed by the sensor includes: the accuracy of the data, the data monitored by the sensor, and the timestamp generated by the data.

 [0049] S203: Determine whether the illuminance value is less than a preset illuminance threshold.

 [0050] After acquiring the illuminance value of the current ambient light, the terminal compares the obtained illuminance value with the preset illuminance threshold, and determines whether the acquired illuminance value is less than a preset illuminance threshold.

[0051] The preset illuminance threshold may be 0.3~llu _X , but is not limited thereto, and the preset illuminance threshold may be other values, which may be set according to actual conditions, and is not limited herein.

 [0052] The terminal determines that the acquired illuminance value is less than the preset illuminance threshold 吋, and recognizes that the current ambient light is dark or insufficient light, and needs to turn on the flash to assist in scanning the two-dimensional code, and step S103 is performed; the terminal determines the obtained illuminance value. When it is greater than or equal to the preset illuminance threshold, no processing is performed, and the two-dimensional code to be identified is directly scanned.

 [0053] S204: When the illuminance value is less than the preset illuminance threshold, turn on the flash and scan the target two-dimensional code to be recognized.

[0054] After determining that the acquired illuminance value is less than the preset illuminance threshold 吋, the terminal activates the flash to illuminate by the flash, and increases the illuminance value of the current environment, so that the target two-dimensional code to be identified is in the light. The line is in a sufficient environment. When the terminal is turned on, the terminal scans the target two-dimensional code to be identified in the scanning range, and the terminal acquires the target two-dimensional code to be identified within the scanning range.

[0055] S205: Parse the target two-dimensional code, and acquire information corresponding to the target two-dimensional code.

[0056] When the terminal acquires the target two-dimensional code to be identified, the terminal uses the two-dimensional code decoding technology to parse the acquired target two-dimensional code to obtain information corresponding to the target two-dimensional code.

[0057] The method for decoding the two-dimensional code is the same as the prior art, and is not described here.

[0058] S206: When the information corresponding to the target two-dimensional code is acquired, the flash is turned off.

[0059] When acquiring the information corresponding to the target two-dimensional code, the terminal turns off the flash to successfully acquire the information corresponding to the target two-dimensional code.

 [0060] In the above solution, when the terminal detects the triggering operation of scanning the two-dimensional code, the terminal collects the illuminance value of the ambient light; determines whether the illuminance value is less than the preset illuminance threshold; and when the illuminance value is less than the preset illuminance threshold The flash is turned on and the target QR code to be recognized is scanned, and the flash can be automatically turned on according to the ambient light illuminance value, saving the time for manually turning on the lighting device, and successfully scanning the two-dimensional code in a dim light environment to improve the light. The efficiency of scanning the two-dimensional code in a darker situation, since the target two-dimensional code is in a well-lit environment after the flash is turned on, the situation of repeatedly scanning the two-dimensional code can be avoided, and the success rate of scanning the two-dimensional code can be improved.

 [0061] After acquiring the information corresponding to the target two-dimensional code, the terminal turns off the flash, and can ensure that the information corresponding to the target two-dimensional code is successfully obtained. The terminal can automatically turn on and off the flash, saving the user the time to control the lighting equipment, simplifying the operation of scanning the QR code in low light environment, and the human-computer interaction is more intelligent.
