Detailed Description
To further illustrate the embodiments, the present application provides the accompanying drawings. The accompanying drawings, which are incorporated in and constitute a part of this disclosure, illustrate embodiments and together with the description, serve to explain the principles of the embodiments. With reference to these matters, one of ordinary skill in the art would understand other possible embodiments and the advantages of the present application. The components in the figures are not drawn to scale and like reference numerals are generally used to designate like components. The term "at least one" means one or more, and the term "plurality" means two or more.
The present application will now be further described with reference to the drawings and detailed description.
The code scanning method provided by the embodiment of the application can be applied to any code scanning equipment to improve the code scanning speed and the code recognition efficiency. The code scanning device is, for example, a code scanning gun, a code scanning box or a code scanning module, and the code scanning device can be handheld, fixed or embedded (embedded in the whole machine), which is not limited in this application.
Fig. 1 is a flow chart of a code scanning method according to an exemplary embodiment of the present application. Referring to fig. 1, the code scanning method provided in the embodiment of the present application includes steps S1 to S5.
S1, responding to detection of scene change, and acquiring a shaking image in the scene, wherein the shaking image comprises an information code to be identified.
In the embodiment of the application, whether the code display device or the commodity waits for the scanned code is judged by detecting whether the ambient brightness in the scene is changed greatly. The step S1 specifically includes: and acquiring the shaking image in response to detecting that the variation of the ambient brightness in the scene exceeds a preset shaking threshold.
In one possible embodiment, the shake image includes a plurality of images acquired at successive times, and may be used to detect whether a moving object, which may be a coding device or merchandise, is present.
The preset shaking threshold value is used for judging whether the change of the environment brightness is caused by shielding of the code display equipment or the commodity.
Wherein, rock the image and mean: the image (also referred to as an image) acquired by the code display device or the commodity when the code display device or the commodity shakes in the image acquisition area of the code scanning device. It can be understood that the shaking image is collected after the scene is detected to change, so that the information code to be identified in the code display device or the commodity can be captured more accurately.
In one possible implementation, after the code scanning device is powered on, the step S1 is performed in the image sensing mode. Optionally, after the code scanning device is powered on, an indication is made, for example, by a prompt tone (for example, a "beep" sound), that the device has entered the working state of the image sensing mode. The image sensing mode may also be called an auto-sensing mode, in which the code scanning device is in a state of monitoring scene change, shoots an image after detecting scene change and performs information code reading, and reenters the state of monitoring scene change after successful reading output of effective information or unsuccessful reading overtime.
In this embodiment of the present application, the information code to be identified includes a bar code and a two-dimensional code, and by way of example, the bar code generally refers to a bar code printed on an outer package of a commodity, and the two-dimensional code refers to a two-dimensional code shown by a user through an electronic screen of a code display device.
Of course, in some embodiments, the electronic screen of the code display device may be a bar code, and at the heart of the application, how to distinguish the electronic screen code from the non-electronic screen code, where the electronic screen code is a two-dimensional code or a one-dimensional code, and the non-electronic screen code is a bar code, the embodiments of the application are exemplified, but not limited to this.
S2, when the ratio of the area of the light spot in the shaking image to the total area of the shaking image exceeds a preset ratio, judging that an electronic screen code appears in the shaking image, and executing S3.
Wherein the preset duty cycle is for example 40%. The flare refers to an area with brightness higher than a preset brightness threshold in the shaking image, the preset brightness threshold can be adjusted according to the ambient brightness, and the flare can be directly fixed and set to 60% of a default brightness value, so that the flare is not limited in the application.
The code scanning device judges whether a plane light spot (i.e., a highlight light spot) with a brightness value exceeding 60% of a default brightness value and an overall area exceeding 40% exists in the shaking image, if so, the current shaking image can be considered to be consistent with the brightness of the electronic screen, and the electronic screen code appears in the shaking image, i.e., the information code to be identified in the current shaking image is the electronic screen code.
In one possible embodiment, the shake image includes a plurality of images acquired at successive times. According to the principle, the plurality of images included in the shaking image are judged, and when two continuous images are judged to have the electronic screen code, the electronic screen code in the shaking image can be judged to appear, namely, the code display device exists in the current scene.
In this embodiment of the present application, an electronic screen code includes: two-dimensional codes or one-dimensional codes shown by an electronic screen, for example, mobile phone payment codes; the non-electronic screen code includes: the bar code shown by the non-electronic screen, for example, a bar code printed on the outer package of the commodity.
And S3, under the condition that the code scanning illuminating lamp is not started, carrying out electronic screen code recognition on the information code to be recognized in the scene.
In the embodiment of the application, after the electronic screen code appears in the shaking image, the code scanning device controls the code scanning illuminating lamp to flash for a preset time period, the code scanning illuminating lamp is turned off, and the electronic screen code recognition is carried out on the information code to be recognized in the scene. The preset duration is, for example, 0.1 seconds.
Through the process, the code scanning device indicates that the electronic screen code is read through the flashing lamp, and reminds the user equipment that the code recognition is started.
In one possible implementation manner, under the condition that the electronic screen code identification is successful, the code scanning device sends out code scanning prompt voice corresponding to the electronic screen code, and the electronic screen code identification flow is ended. The scan code prompt tone corresponding to the electronic screen code is, for example, "welcome payment with mobile phone". Further, different payment channels corresponding to the electronic screen codes can be embodied in the prompt tone.
In one possible implementation, the code scanning device reads the identification duration in case the electronic screen code identification is unsuccessful. The identification duration is the identification duration of this time, and can be calculated from the time of turning off the lighting lamp after flashing. If the duration of the code identification does not exceed the preset duration, continuing the code identification; if the duration of the identification code exceeds the preset duration, step S1 is executed. The preset duration is 2 seconds, in this example, if the duration of the identification code does not exceed 2 seconds, the identification is continued, and the content of the two-dimensional code is judged until the identification is successful within 2 seconds; if the identification duration exceeds 2 seconds, the operation state of the image sensing mode is re-entered (step S1).
And S4, when the ratio of the area of the light spot in the total area of the shaking image does not exceed the preset ratio, judging that a non-electronic screen code appears in the shaking image, and executing the step S5.
This step is described with reference to step S2, and is not described here in detail.
S5, under the condition that the code scanning illuminating lamp is turned on, non-electronic screen code recognition is conducted on the information code to be recognized in the scene.
In the embodiment of the application, after judging that the non-electronic screen code appears in the shaking image, the code scanning device turns on the code scanning illuminating lamp, and enters the commodity bar code identification flow, and the bar code content is judged. For example, the commodity barcode identification process may be a european commodity number (European Article Number, EAN) code, which is a commodity barcode specification established by the international association for coding articles.
In one possible implementation manner, under the condition that the non-electronic screen code identification is successful, the code scanning device turns off the code scanning illuminating lamp, sends out code scanning prompt voice corresponding to the non-electronic screen code, and ends the non-electronic screen code identification flow. The scan code prompt voice corresponding to the non-electronic screen code is, for example, "scan code successful".
In one possible implementation, the code scanning device reads the identification duration in case the non-electronic screen code identification is unsuccessful. The identification duration is the identification duration of this time, and can be calculated from the time of starting the lighting lamp. If the duration of the code identification does not exceed the preset duration, continuing the code identification; if the duration of the identification code exceeds the preset duration, step S1 is executed. Illustratively, the preset duration is 2 seconds, in this example, if the code identification duration does not exceed 2 seconds, continuing to identify and read, and judging the content of the bar code until the identification is successful within 2 seconds; if the identification duration exceeds 2 seconds, the operation state of the image sensing mode is re-entered (step S1).
In order to facilitate understanding of the technical solution provided in the foregoing embodiments, the present application provides a flow chart of another code scanning method according to an exemplary embodiment. Referring to fig. 2, the code scanning method includes the following steps a to f.
Step a, the code scanning device is in an image sensing mode after being powered on (refer to step S1).
And b, detecting whether a shaking image exists in the scene, if so, executing the step c, and if not, returning to the step a.
And c, judging the type of the information code to be identified according to the light spot area in the shaking image, if the light spot area ratio exceeds the preset ratio, executing the step d, and if the light spot area ratio does not exceed the preset ratio, executing the step e.
Step d, the lighting lamp is turned off after flashing for 0.1 second, and an electronic screen code identification process is entered; if the reading is successful, after a corresponding code scanning prompt tone (for example, prompting a payment mode corresponding to a mobile phone payment code) is sent out, the step g is entered; if the reading is unsuccessful, the step f is entered.
Step e, turning on the illuminating lamp, and entering a non-electronic screen code (commodity bar code) identification process; if the reading is successful, after a corresponding code scanning prompt tone (for example, the code scanning is successful) is sent out, the step g is entered; if the reading is unsuccessful, the step f is entered.
And f, judging whether the duration of the identification code exceeds the preset duration, if not, continuing to identify and read, and if so, returning to the step a.
Step h, judging whether the shaking image stops (the shielding object leaves) according to the non-electronic screen code, and returning to the step a if the shaking image leaves; and d, aiming at the electronic screen code, judging whether the light spot characteristics disappear, and returning to the step a if the light spot characteristics disappear.
According to the scheme, the interference caused by light reflection can be avoided when the electronic screen is not polished, the bar codes can be conveniently and rapidly identified when the commodity bar codes are polished, the efficient code scanning can be realized in a scene where the commodity bar codes and the two-dimension codes of the electronic screen are mixed, the light reflection or the excessive brightness of the electronic screen can be avoided, the effective light supplementing can be carried out on the commodity bar codes, the efficient double-code identification effect is realized, and the code scanning speed is greatly improved.
