In order to explain technical contents, achieved objects, and effects of the present invention in detail, the following description is made with reference to the accompanying drawings in combination with the embodiments.
The most key concept of the invention is as follows: the camera is guided to align the two-dimensional code through the guide lamp, and scanning is carried out.
Referring to fig. 1, an embodiment of the present invention provides a two-dimensional code alignment scanning method, including the following steps:
s1: the camera aligns the two-dimensional code through the guide lamp;
s2: scanning the two-dimensional code to obtain a scanned image, and sending the scanned image to an image processing module through a sensor;
s3: and the image processing module processes and decodes the scanned image.
As shown in fig. 2, before step S1, the second embodiment of the present invention further includes:
s01: respectively connecting the camera and the image processing module with the sensor;
s02: and a guide lamp is integrated on the camera.
Generally, the image processing module may be a CPU. In the actual design and production process, a high-performance sensor can be matched with a high-definition lens, and the sensor is directly connected with a CPU (central processing unit) of a product through a CSI (channel state information) interface or an MIPI (million instructions per second) interface.
High definition digtal camera can integrate the pilot lamp, and the pilot lamp then is used for guiding the position of scanning, opens the pilot lamp promptly after, according to the irradiation range of guiding light, the camera is synchronous to be removed thereupon to acquire the concrete position of two-dimensional code, and preferably, adjustable pilot lamp and the distance of two-dimensional code and the focus of itself, make whole two-dimensional code all contain in the irradiation range of guiding light, in order to acquire complete two-dimensional code information. The camera is integrated with the guide lamp, so that the size of the whole device can be reduced, and the miniaturization is realized. In another embodiment, the guiding lamp and the camera can be arranged separately, and only the two can be ensured to move synchronously.
After step S02, the method further includes:
s03: and a light supplement lamp is integrated on the camera.
The light supplement lamp is used for supplementing the brightness of the picture under the low-illumination environment. As described above, the light supplement lamp is integrated into the camera, also for the sake of miniaturization of the apparatus. And under other circumstances, the light filling lamp can separately set up with the camera, only needs to guarantee that the light filling lamp can realize the light filling effect to the two-dimensional code to make the camera acquire enough light intensity can.
After step S2, the method further includes:
s21: the image processing module sends the scanned image to the display module;
s22: the camera acquires an alignment correction instruction of a scanned image through a display module;
the execution returns to step S1.
Specifically, in the implementation of the two-dimensional code scanning function in the embodiment of the present invention, the sensor continuously sends the image to the system CPU, and the CPU performs image processing and decoding, and sends a prompt after decoding is successful.
When the sensor sends the image to the CPU, the CPU can send the image to the display screen for displaying according to the requirement, so that a user can align and correct the image, and the camera obtains more accurate alignment scanning through alignment correction, so that the accuracy can be improved.
After step S2, the method further includes:
s23: the image processing module converts the scanned image into a YUV format;
s24: judging whether the Y component value is smaller than a preset value or not;
if yes, go to step S25: controlling the light supplement lamp and turning on the guide lamp; and returns to perform step S2;
otherwise, step S21 or S3 is executed.
If illumination intensity is not enough promptly appears, and when influencing the camera and acquire the two-dimensional code scanning, the accessible sets up the light filling lamp and carries out the light filling. Specifically, the scanned image received by the CPU is converted into YUV format, and the processing is effective to determine the luminance information of the scanned image by indicating the Y component of the luminance value, and determine whether it is lower than a predetermined value, so as to selectively turn on the fill light.
If the integral Y component value is smaller than the set value, the current decoding state is directed at a non-self-luminous decoding object, and the light supplementing lamp and the guiding lamp need to be turned on at the moment, so that the rapid guiding in the state is realized.
If the integral Y component value is larger than the set value, the current state is directed at the self-luminous object, and the light supplementing lamp and the guiding lamp are turned off at the moment for scanning.
In other embodiments, a camera preview interface can be further opened, and quick guidance is realized in a preview + alignment mode.
In the second embodiment of the invention, the guide lamp and/or the light supplement lamp are/is integrated on the camera, so that the miniaturization of the equipment can be realized. Simultaneously through the mode that increases preview alignment, realize the alignment scanning of higher accuracy, and under the condition of external light intensity, open the light filling lamp and realize the scanning to obtain complete two-dimensional code information, not only the simple operation, user experience degree also obtains promoting moreover.
