Furthermore, the particular features, structures, materials, or characteristics described may be combined in any suitable manner in any one or more embodiments or examples.
Referring to fig. 1, in a first aspect, some embodiments of the present invention provide a two-dimensional code detection method, including but not limited to step S110, step S120, step S130, and step S140.
Step S110: acquiring a plurality of image information;
step S120: identifying position change information of an object in the plurality of image information;
step S130: determining a cutting mode of the image information according to the position change information to obtain a cut picture;
step S140: and detecting and identifying the cut picture to obtain and send identification information.
Specifically, in the present embodiment, the image information may be a plurality of pieces of image information obtained by extracting video frame image information from video information, or may be a plurality of pictures. And judging whether the position information of the object in the image changes or not by comparing the plurality of image information, and determining the cutting mode of the image information according to the position change information to cut so as to obtain a cut picture. And detecting and identifying the cut picture to obtain identification information, and sending the identification information out so as to facilitate the device using the detection method to carry out the next operation according to the identified two-dimensional code. By identifying whether the position information of the object in the image information changes or not and determining the cutting mode to cut the image information, the consumption of a CPU (central processing unit) can be reduced, and the detection and identification efficiency of the two-dimensional code can be improved.
Referring to fig. 2, in some embodiments of the present invention, the cutting manner includes a first cutting manner and a second cutting manner, and the step S130 includes, but is not limited to, the step S210 and the step S220.
Step S210: if the position change information is changed, determining a picture set according to a time interval between adjacent image information and a preset first time threshold, and cutting pictures in the picture set in a first cutting mode to obtain a first cut picture;
step S220: and if the position change information is unchanged, determining the static picture according to the image information and a preset second time threshold, and cutting the static picture in a second cutting mode to obtain a second cut picture.
In step S210, if the position change information in the image is determined to be changed, a picture set is selected from the plurality of image information according to a preset first time threshold, and the image information that does not meet the condition is ignored, so as to prevent excessive CPU consumption due to over-frequency. Such as: the first time threshold is preset to be 1 second, and the acquired image information is continuous and has a plurality of image information, and many image information in the plurality of image information are similar. If each image information is cut, detected and identified, the CPU must be over-frequency and over-consumption, even the CPU cannot work normally. Therefore, a part of image information is selected from the plurality of image information as a picture set every preset first time threshold (for example, 1 second), and then the picture set is cut in a first cutting mode, so that the frequency of the CPU can be reduced, and the loss of the CPU can be reduced.
Referring to fig. 3, in some embodiments of the present invention, step S210 includes, but is not limited to, step S310, step S320, step S330, and step S340.

By screening the size information of the objects, the objects which are too small in size, too long and too flat in shape and the like and cannot contain the two-dimensional codes are filtered, and if no effective objects exist after filtering (namely all the objects cannot contain the two-dimensional codes), the current detection and identification are quitted, subsequent operation is not performed, and the next image information is waited.
Through setting up like this, can further reduce CPU's energy consumption, simultaneously, utilize the CPU resource of saving out, can suitably increase the detection frequency to improve the timeliness of two-dimensional code detection.
In step S330, the object positions in the plurality of first images obtained in step S320 are merged to generate a first cropping frame including all objects that may have two-dimensional codes and may move, and unrelated picture information is cropped and deleted to reduce the energy consumption of the CPU.
Referring to fig. 4, in some embodiments of the present invention, step S220 includes, but is not limited to, step S410 and step S420.

step S420: and cutting according to the static picture and a preset cutting frame to obtain a second cutting picture.
Specifically, in this embodiment, if it is determined that the position change information in the image is not changed, the still picture is determined by using a preset second time threshold (the preset second time threshold is usually greater than the preset first time threshold), and if the time is not reached, the image information is not acquired or any operation is not performed on the acquired image information. Such as: and judging that the position change information in the image is unchanged, and if the preset second time threshold is 5 seconds, cutting the image information once by using the preset cutting frame (or not cutting the image information) at intervals of 5 seconds, detecting and recognizing, and if the other time is not operating the image. The preset cutting frame can be a square frame and the like. Thus, the frequency of the CPU can be further reduced, and the loss of the CPU can be reduced.
In some embodiments of the invention, the identification information comprises any one of: networking information, payment information, transmission information and commodity information. If the identification information comprises the payment information, the payment information is detected and identified and is sent to the corresponding payment module, and the payment module carries out payment according to the payment information.
If the identification information comprises commodity information, the two-dimensional code detection method is used for a warehousing device of a warehouse. The camera of the warehousing device is fixed at one position, collects a plurality of image information and sends the image information to the position identification module of the warehousing device; the position identification module identifies position change information of an object in the image information and sends the position change information to the judgment module; the judging module judges whether the object moves according to the position change information and outputs a judgment result to the processing module; the processing module selects a cutting mode according to the judgment result, cuts the image information to obtain a cut picture, and sends the cut picture to the detection module; the detection module detects and identifies the cut picture to obtain commodity information, and sends the commodity information to the application module so as to realize warehousing of commodities. In the image information collection, whether the camera scans the two-dimensional code cannot be judged, so that the image information is operated in the steps S210 and S220, the frequency of a CPU (central processing unit) can be reduced, the loss of the CPU can be reduced, meanwhile, the detection frequency can be properly increased by using the saved CPU resource, the timeliness of two-dimensional code detection is improved, and the efficiency of commodity warehousing is improved.

Referring to fig. 5, in some embodiments of the invention, step S140 includes, but is not limited to, step S510, step S520, and step S530.
Step S510: acquiring pattern change information in adjacent cut pictures;
step S520: determining the position of a two-dimensional code pattern in the cut picture according to the pattern change information;
step S530: and detecting and identifying the two-dimensional code pattern in the cut picture to obtain and send identification information.
Specifically, in the present embodiment, the two-dimensional code pattern may be on a display device such as a mobile phone or a tablet computer. The color, the position or the size of the two-dimensional code pattern on the display equipment are periodically changed, so that the two-dimensional code scanning equipment can conveniently position the two-dimensional code, and the quick identification of the two-dimensional code is realized.
The two-dimensional code detection method according to the embodiment of the present invention is described in detail with reference to fig. 1 to 4. It is to be understood that the following description is illustrative only and is not intended to be limiting of the invention.
In this embodiment, a plurality of image information is acquired, wherein the image information may be a plurality of image information extracted from the video information or a plurality of pictures. And the image information is identified and judged to determine whether the object in the image information moves, namely whether the position change information is changed.
If the position change information in the image is judged to be changed, a picture set is selected from the plurality of image information by using a preset first time threshold, and the image information which does not meet the condition is ignored, so that the condition that the CPU consumption is too large due to over-frequency is prevented. Such as: the first time threshold is preset to be 1 second, and the acquired image information is continuous and has a plurality of image information, and many image information in the plurality of image information are similar. If each piece of image information is cut, detected and identified, the CPU will consume too much frequency and even fail to work normally, and therefore, a part of image information is selected from the plurality of pieces of image information as a picture set without a preset first time threshold (e.g., 1 second).
And screening the determined picture set through the size information of the object to obtain a plurality of first images, wherein the size information comprises size, shape and the like. By screening the size information of the objects, the objects which are too small in size, too long and too flat in shape and the like and cannot contain the two-dimensional codes are filtered, and if no effective objects exist after filtering (namely all the objects cannot contain the two-dimensional codes), the current detection and identification are quitted, subsequent operation is not performed, and the next image information is waited.
Combining the object positions in the obtained plurality of first images to generate a first cutting frame containing all objects which possibly have two-dimension codes and are possible to move, cutting and deleting irrelevant picture information to reduce the energy consumption of a CPU (Central processing Unit), and simultaneously, utilizing the saved CPU resource, properly increasing the detection frequency so as to improve the timeliness of two-dimension code detection.
If the position change information in the image is judged to be unchanged, the static image is determined by using a preset second time threshold (the preset second time threshold is usually larger than the preset first time threshold), and if the time is not up, the image information is not acquired or any operation is not performed on the acquired image information. Such as: and judging that the position change information in the image is unchanged, and if the preset second time threshold is 5 seconds, cutting the image information once by using the preset cutting frame (or not cutting the image information) at intervals of 5 seconds, detecting and identifying the image information, and if the position change information in the image is unchanged, not operating the image at other times. The preset cutting frame can be a square frame and the like.
According to the two-dimensional code detection method, whether the position information of the object in the image information changes or not is identified, the image information is cut in a determined cutting mode, different cutting frames and different cutting modes are determined according to different conditions, accordingly, the consumption of a CPU (central processing unit) can be reduced, meanwhile, the detection frequency can be properly increased by means of saved CPU resources, and the timeliness of two-dimensional code detection is improved.
