Detailed Description
The following detailed description of the present invention, when taken in conjunction with the drawings and the detailed description of the invention, is not to be taken as limiting the invention.
As shown in attached figures 1-2, an automatic code scanning device for electric materials comprises a fixing mechanism 1, a roller conveyer belt 2 and a code scanning mechanism 3, wherein the code scanning mechanism 3 is arranged on the fixing mechanism 1, a transformer automatic guided transport vehicle automatic warehouse entering area automatic code scanning station is arranged on the roller conveyer belt 2, electronic materials are arranged on a tray 8, at least two CCD image recognition cameras 401 are arranged on two sides of the roller conveyer belt 2, a tray code 5 and a material two-dimensional code 6 are scanned, information is uploaded to a system in an Ethernet communication mode to bind the information, at least six CCD image recognition cameras 401 are arranged on the same side of the roller conveyer belt 2, the two cameras at two ends scan the material two-dimensional code, the camera at the middle part scans the only code of the tray, a photoelectric sensor 7 is arranged on the roller conveyer belt 2, when the roller conveyer belt 2 conveys the materials to a scanning area, the photoelectric sensor 7 senses the hard trigger camera to work, decoding software decodes the received task, and effective information is transmitted to the system through the local area network after decoding is finished; wherein, sweep sign indicating number mechanism 3 and be used for the automatic sign indicating number of sweeping of goods and materials, the two-dimensional code data plate of application two-dimensional code discernment and image preprocessing to random position carries out accurate discernment.
Preprocessing the image before the identification, wherein the preprocessing of the two-dimensional code comprises the following steps: graying an image, enhancing the image, filtering the image, processing uneven illumination, binaryzation, edge detection, positioning the image, correcting the image and correcting distortion; the two-dimensional code is recognized by recovering the contained information through mathematics and image methods of the collected image to perform image recognition, searching the characteristics of the image through image recognition, highlighting the capture and recognition of the characteristics, recognizing the image through effective information in the image, judging the content of the image, analyzing the represented meaning, compiling a computer program simulating human image recognition activity, obtaining an image recognition model, and recognizing the image if the image characteristics are matched with the sensory stimulation of the human brain in memory when capturing a certain image; the code scanning mechanism 3 is matched with code scanning setting software and code scanning setting software, the code scanning setting software is used for setting the using mode, the focusing mode, the communication mode and the picture splicing related parameters of the CCD image recognition camera, and the decoding software is used for analyzing the one-dimensional code/two-dimensional code scanned by the CCD image recognition camera to obtain information, actively sending the analyzed information to a system and butting the analyzed information with a storage management system;
the automatic code scanning software is connected with the warehousing management software in an abutting mode; splicing the images of the two cameras at the position of the overlapping area of the two-dimensional code; the distance between the camera and the electric power material is set to be 250-350 mm.
The two-dimensional code recognition is a process of recovering information contained in a captured image as much as possible by a mathematical and image method, but the image captured by any instrument is inevitably different from an original image. If various noises, blurs, uneven illumination and distortion exist in the image acquisition process, even the contamination of partial image areas, the image preprocessing is needed before the identification, and the smooth reading of the bar code can be ensured as much as possible.
The preprocessing of the two-dimensional code comprises the following steps: the method comprises the steps of image graying, image enhancement, image filtering processing, uneven illumination processing, binarization, edge detection, image positioning, image correction, distortion correction and the like.
In connection with image recognition, the emphasis of image recognition is to find the features of an image, such as the capital letters of English, A has a sharp corner, O has a circle, and Y can be basically regarded as a line and a sharp corner and an obtuse corner, so that for capturing and recognizing special information, namely, the salient features, the image can be recognized through effective information in the image, the content and the property of the image can be judged, and the meaning represented by the image can be analyzed.
In order to imitate the principle of human eye recognition image and achieve the effect of human eye recognition, scientists program a computer program simulating human image recognition activity, thereby acquiring a plurality of recognition models related to image recognition, and when a computer captures a certain image, if the image characteristics are matched with the sensory stimulation of human brain in memory, the image is considered to be recognized.
Analyzing the bin type specification to know that the height range of the two-dimensional code label side is 1.5 meters by 1.3 meters, and a single code scanner can only cover the visual field of about 0.3 meters by 0.3 meters, so that a plurality of CCD image recognition cameras need to be deployed to work simultaneously. The two-dimensional code label of transformer is in random one side, so need install the camera in the line both sides of moving.
Accurately identifying the two-dimensional code nameplate at the random position by using a two-dimensional code identification technology and an image preprocessing technology; and interfacing the automatic code scanning software with the warehousing management software.
