Technical Field
The embodiment of the disclosure relates to the technical field of security inspection equipment, in particular to a cargo security inspection sorting system and method based on integral image comparison.
Background
At present, the logistics industry uses an automatic sorting machine system to sort cargoes, so that sorting efficiency is improved. The automatic sorting machine system generally comprises a control device, a sorting device, a conveying device and a sorting crossing. The control device is used for identifying, receiving and processing sorting signals, and indicating the sorting device to automatically sort the cargoes according to the kinds of the cargoes, the delivery places of the cargoes or the categories of owners according to the requirements of the sorting signals. These sorting demands can be input into the control device of the automatic sorting machine system in different ways, such as bar code scanning, weight detection, height detection, shape recognition and the like, and the control device determines which sorting crossing a certain cargo should enter according to the judgment of the sorting signals. The sorting device is used for executing sorting action according to the sorting instruction sent by the control device. When goods having the same sorting signal pass through the sorting device, the sorting device performs a sorting action by changing the direction of travel of the conveying device so that the goods enter the other conveyor or enter the corresponding sorting gate.
Currently, in the logistics industry, photographing goods and performing classification actions through image analysis can be adopted. Image acquisition equipment is arranged on the security inspection machine and the sorting machine respectively so as to acquire the appearance diagrams of cargoes entering the security inspection machine and the sorting machine respectively. When the security inspection machine detects that the goods are dangerous goods, the goods appearance diagram collected at the corresponding security inspection machine is marked, then the marked goods appearance diagram is compared with the goods appearance diagram collected at the sorting machine, and if the goods are consistent, the goods at the sorting machine are dangerous goods, and the dangerous goods are required to be sorted out by the sorting machine, so that the dangerous goods are positioned and sorted.

Detailed Description
The technical scheme of the present disclosure is further specifically described below by way of examples and with reference to the accompanying drawings. In the specification, the same or similar reference numerals denote the same or similar components. The following description of the embodiments of the present disclosure with reference to the drawings is intended to illustrate the general inventive concept of the present disclosure and should not be taken as limiting the disclosure.
Furthermore, in the following detailed description, for purposes of explanation, numerous specific details are set forth in order to provide a thorough understanding of the embodiments of the present disclosure. It may be evident, however, that one or more embodiments may be practiced without these specific details. In other instances, well-known structures and devices are shown in the drawings in order to simplify the drawings.
According to one general technical concept of the present disclosure, there is provided a cargo security inspection sorting system including: a security inspection machine for performing security inspection of the goods; the sorting machine is used for distributing the goods subjected to the security inspection to the corresponding sorting channels; and a conveyor belt for conveying the goods to the sorter via the security inspection machine; wherein, be provided with non-periodic and non-repetitive pattern on the conveyer belt to every goods that are located on the conveyer belt and the background pattern characteristic that this goods is located constitute the whole picture that is exclusively used in this goods jointly, wherein the background pattern characteristic is part of non-periodic and non-repetitive pattern.
According to another general technical concept of the present disclosure, there is provided a cargo security inspection sorting method including: forming an overall diagram special for each cargo by the cargo on a conveyor belt and a background pattern feature on the conveyor belt where the cargo is located, wherein the conveyor belt is provided with a non-periodic and non-repetitive pattern, and the background pattern feature is a part of the non-periodic and non-repetitive pattern; collecting a first integral diagram specific to each cargo passing through a security check machine; collecting a second overall map specific to each cargo passing through the sorting machine; and comparing the first whole image acquired by a first image acquisition device arranged at the security inspection machine with the second whole image acquired by a second image acquisition device arranged at the sorting machine; if the two are the same, the sorting machine is controlled to distribute the goods to the corresponding sorting channels.
According to an exemplary embodiment of the present disclosure, a cargo security inspection sorting system based on image comparison is provided, and belongs to the technical field of security inspection equipment. Referring to fig. 1 and 2, a cargo security inspection and sorting system, comprising: a security inspection machine 10 for performing security inspection of goods G; sorting machines 20 for distributing the security checked goods G to respective sorting channels 201, 202; and a conveyor belt 30 for conveying the goods G via the security check machine 10 to the sorting machine 20. According to the present disclosure, the non-periodic and non-repetitive pattern 300 is provided on the conveyor belt 30 such that each good G located on the conveyor belt 30 together with the background image features T on which the good G is located form an overall map P specific to the good G, wherein the background image features T are part of the non-periodic and non-repetitive pattern 300. That is, according to the design concept of the present disclosure, a background image feature having a distinction is added to each cargo located on a conveyor belt using a non-periodic and non-repetitive pattern on the conveyor belt, then an overall map specific to the cargo, which is composed of each cargo together with the background image feature in which the cargo is located, is collected, and finally positioning and sorting differentiation of the cargo is performed using the overall map specific to each cargo having a distinction.
According to an embodiment of the present disclosure, the non-periodic and non-repeating pattern 300 on the conveyor belt 30 described above includes, but is not limited to: a persistence differential texture; and/or, a persistent difference pattern. For example, fig. 2 shows a pattern 300 embodied as a continuous differential texture disposed (e.g., sprayed) on a conveyor belt 30. Of course, the non-periodic and non-repetitive pattern 300 is not limited to the above, and for example, the non-periodic and non-repetitive pattern 300 may be a pattern designed based on the non-periodic tile theory proposed by the physicist Roger Penrose (Roger Penrose). Based on this theory, for example, two diamond shapes of different shapes can be used to form a pattern that can achieve five-fold symmetry and continue indefinitely without repeating itself. In this way, the cargo security inspection sorting system provided by the present disclosure sets (e.g. sprays) a specific non-periodic and non-repetitive differential texture or differential pattern for distinguishing positions on the whole conveyor belt, so that after the cargo G and the background image feature T thereof are obtained together to form the whole map P, the cargo G can be distinguished and positioned relatively easily.
According to an exemplary embodiment of the present disclosure, referring to fig. 1 and 2, the cargo security check-up system further includes: a first image acquisition device (e.g. a first camera) 11 and a second image acquisition device (e.g. a second camera) 21. The first image acquisition device 11 is disposed at the security inspection machine 10 (for example, disposed at an entrance of the security inspection machine 10) and is configured to acquire a first overall map Pl specific to each cargo G passing through the security inspection machine 10. A second image acquisition device 21 is provided at the sorting machine 20 (for example at the inlet of the sorting machine 20) for acquiring a second overall map P2 specific to each good G passing through the sorting machine 20. Further, the cargo security inspection and sorting system further comprises: a first triggering device 12 and a second triggering device 22. The first triggering device 12 is provided at the security inspection machine 10 (for example, at an entrance of the security inspection machine 10) for triggering an image capturing operation of the first image capturing device 11 when the presence of the goods G at the security inspection machine 10 is detected. A second triggering device 22 is provided at the sorting machine 20, for example at the entrance of the sorting machine 20, for triggering an image acquisition operation of the second image acquisition device 21 upon detection of the presence of a load G at the sorting machine 20. According to an embodiment of the present disclosure, the conveyor 30 may be a conveyor common to the security check machine 10 and the sorter 20. Two or more sorting channels 201 and 202 are also provided in the sorting machine 20, and the sorting channels are allocated with corresponding drives. Through the above construction, when the first triggering device 12 detects that the goods G exist at the entrance of the security inspection channel of the security inspection machine 10, an image acquisition instruction is sent to the first image acquisition device 11, and the first image acquisition device 11 performs image acquisition on the goods G and the background image features thereof on the conveyor belt 30 at the entrance of the security inspection channel after receiving the instruction, so as to obtain a first integral image P1 which is formed by the goods G and the background image features T of the goods G and is specific to the goods G. Then, when the second triggering device 22 detects that the goods G exist at the entrance of the sorting machine 20, an image acquisition instruction is sent to the second image acquisition device 21, and after the second image acquisition device 21 receives the instruction, the goods G on the conveying belt 30 positioned at the entrance of the sorting machine 20 and the background image features thereof are subjected to image acquisition again, so as to obtain a second integral image P2 which is formed by the goods G and the background image features T of the goods G and is specific to the goods G.
Furthermore, in accordance with an embodiment of the present disclosure, referring to fig. 1 and 2, the cargo security inspection sorting system further includes: the controller may be, for example, a cloud server. The controller is configured to: comparing the first overall map P1 acquired by the first image acquisition device 11 with the second overall map P2 acquired by the second image acquisition device 21; if the two are identical, the sorter 20 is controlled to sort the goods G to the corresponding first sorting channel 201 or second sorting channel 202. Further, in an exemplary embodiment where contraband (e.g., dangerous goods) need to be inspected, the controller is further configured to: when the security inspection machine 10 detects that the goods G are forbidden goods, the forbidden goods G are marked; and comparing the first overall map P1 for the contraband acquired by the first image acquisition means 11 with the second overall map P2 for the contraband acquired by the second image acquisition means 21; if the two are the same, the marked good G is determined to be contraband and the sorter 20 is controlled to dispense the contraband G to a contraband sorting channel (e.g., a first sorting channel) 201. In this way, the security inspection machine 10 detects the goods G entering the security inspection channel; when the cargo G is detected as contraband cargo, the controller marks the contraband cargo on the received first whole image sent by the first image acquisition device 11, and generates an allocation instruction. The controller compares the second integral image acquired by the second image acquisition device 21 received after the allocation instruction is generated with the first integral image, if the comparison is successful, the contraband goods are determined, and the controller controls the sorter 20 to start so as to sort the contraband goods G to the corresponding contraband goods sorting channel. Therefore, the cargo security inspection sorting system provided by the disclosure can rapidly, automatically and accurately realize the sorting of dangerous suspected cargoes, particularly can effectively distinguish cargoes similar in appearance and size, and greatly provides the efficiency of the security inspection sorting system.
Meanwhile, the exemplary embodiment of the disclosure also discloses a cargo security inspection sorting method. The cargo security inspection sorting method can comprise the following steps: forming an overall diagram special for each cargo by the cargo on a conveyor belt and a background pattern feature on the conveyor belt where the cargo is located, wherein the conveyor belt is provided with a non-periodic and non-repetitive pattern, and the background pattern feature is a part of the non-periodic and non-repetitive pattern; collecting a first integral diagram specific to each cargo passing through a security check machine; collecting a second overall map specific to each cargo passing through the sorting machine; and comparing the first whole image acquired by a first image acquisition device arranged at the security inspection machine with the second whole image acquired by a second image acquisition device arranged at the sorting machine; if the two are the same, the sorting machine is controlled to distribute the goods to the corresponding sorting channels. In the above cargo security inspection sorting method, as described above, the non-periodic and non-repetitive pattern on the conveyor belt is employed including: a persistence differential texture; and/or, a persistent difference pattern. For example, the non-periodic and non-repeating pattern 300 may be a pattern designed based on non-periodic tile theory proposed by the physicist Roger Penrose. Based on this theory, for example, two diamond shapes of different shapes can be used to form a pattern that can achieve five-fold symmetry and continue indefinitely without repeating itself. According to an exemplary embodiment of the present disclosure, the cargo security inspection sorting method further includes: triggering the image acquisition operation of the first image acquisition device when the goods exist at the security inspection machine; and triggering an image acquisition operation of the second image acquisition device upon detecting the presence of a good at the sorter. According to an exemplary embodiment of the present disclosure, the cargo security inspection sorting method further includes: when the security inspection machine detects that the goods are forbidden goods, the forbidden goods are marked; comparing the collected first integral map about the contraband with the collected second integral map about the contraband; and if the two types of the illegal cargoes are the same, controlling the sorting machine to distribute the illegal cargoes to a sorting channel of the illegal cargoes.
Through the cargo security inspection sorting system and the cargo security inspection sorting method based on the whole image comparison, which are provided by the various exemplary embodiments of the disclosure, the correct sorting of cargos (such as the correct sorting of forbidden cargos with dangerous suspects) can be quickly, automatically and accurately realized, particularly cargos with similar appearance and size can be effectively distinguished, and the efficiency of the security inspection sorting system is greatly improved.
