[0002] The tourist identity recognition method using a snapshot image face recognition method is a modern park management technology applied to scenic spots, amusement parks and other places. The method is usually integrated in a gate device, aiming to verify the tourist identity credentials (such as ID cards, ticket barcodes) and capture their face images, to realize the binding of identity information and biological characteristics, so as to complete safe and efficient park entry verification, and provide data basis for subsequent tourist service and management in the park (such as non-contact payment, lost person searching, passenger flow analysis);

[0003] At present, the existing such methods and systems generally use the following technical means: a gate device with an identity recognition area (such as a card reader, a two-dimensional code scanner) and a face snapshot camera is set at the entrance of the park.

[0089] The patrol module is used for patrolling the unmanned aerial vehicle 76 according to the corresponding code through the control module;

[0090] The feedback module is used for feeding the visitor position corresponding to the code image information patrolled by the patrol unmanned aerial vehicle 76 to the display module for display.

[0091] In combination Figures 1-12 As shown, the specific processing process of the patrol module for patrolling the unmanned aerial vehicle 76 according to the corresponding code through the control module is as follows:

[0092] The motor 753 above the support rod 41 at the last time of collecting the code corresponding image information is controlled to work through the control module, and the two top covers 74 are reversely rotated around the two hinged shafts one by one through the motor 753, so as to open the sealing area;

[0093] The driving rod four 8 is controlled to move downward through the control module, so that the charging head 82 is separated from the charging seat 762;

[0094] The patrol unmanned aerial vehicle 76 is controlled to take off through the control module, and the surrounding of the support rod 41 in the park is patrolled until the visitor corresponding to the code image information is patrolled.

[0095] Working principle and use process of the application:

[0096] After the visitor purchases the park ticket by using the personal ID card, when entering the park through the park entrance, first, the personal ID card is placed in the identity recognition area 11, (or the purchased ticket two-dimensional code is placed in the identity recognition area 11, or the electronic coupon two-dimensional code is placed in the identity recognition area 11), and then the identity recognition area 11 is used for recognition, after the identity information recognition, the visitor personnel adjusts the horizontal angle or the pitch angle of the face recognition all-in-one machine 23 through the button on the adjusting panel 3 according to the height of the visitor personnel, so that the shooting angle of the face recognition all-in-one machine 23 is opposite to the face of the visitor, so that the face image of the visitor is captured, the shooting angle of the face recognition all-in-one machine 23 is adjusted according to the height of the visitor, the face image capturing condition when entering the park is effectively avoided, and the visitor can smoothly enter the park.

[0097] The face recognition all-in-one machine 23 captures the face of the visitor, the image acquisition module acquires the image captured by the face recognition all-in-one machine 23 and transmits it to the encoding module, the encoding module encodes the image information acquired by the image acquisition module, and the position generation module generates the position of the acquired image and synchronously transmits it to the database module for storage; at this time, the control module controls the drive rod one 124 to rotate the gate rod 123 on the mounting seat 122 to be vertical, canceling the blockage of the passage formed between the gate seat one 12 and the gate seat two 13, so that the visitor can enter the park through the passage between the gate seat one 12 and the gate seat two 13; during this period, when the visitor walks between the infrared emitting sensor and the infrared receiving sensor, the visitor blocks the light beam between the infrared emitting sensor and the infrared receiving sensor, and the receiving end cannot receive the signal, so it can be known that the visitor has passed the gate rod 123; at this time, the control module controls the drive rod one 124 to rotate the gate rod 123 on the mounting seat 122 to be horizontal, blocking the passage formed between the gate seat one 12 and the gate seat two 13, so that the next visitor can enter the park;

[0098] During the period when the visitor enters the park for sightseeing, when passing through each image acquisition device 4, the face recognition camera one 43 on the acquisition device 4 captures the face of the passing visitor to generate image information, the image comparison module compares the newly generated image information with the stored image information in the database module, and the data update module updates the acquisition image position in real time and transmits it to the database module for storage, so as to realize real-time recording of the visitor's position; during this period, when the visitor walks to the image acquisition device, the visitor can observe the corresponding scenic spot through the direction indicator 64 on the support rod 41, so as to facilitate the visitor to quickly go to the scenic spot he wants to visit;

[0099] When the same row of tourists get lost and the park needs to cooperate to quickly find them, other tourists passing by are ready to provide the photo image information of the lost tourists, the photo image information of the tourists is input through the image input module, the image information is compared with the database module through the comparison module, the corresponding code of the image information is called, after the corresponding code of the image information is called, the motor 753 above the support rod 41 where the last collected image information corresponding to the code is controlled to work through the control module, the rotating rod 751 is driven to rotate through the bevel gear assembly two 754, the two hinged shafts one are reversely rotated through the two groups of bevel gear assemblies one 752, the two top covers 74 are reversely rotated around the two hinged shafts one respectively, and the sealing area is opened. At this time, the driving rod four 8 is controlled by the control module to move the mounting plate 81 downward, so that the charging head 82 is separated from the charging seat 762, and the patrol unmanned aerial vehicle 76 takes off for patrol around the support rod 41 in the park, until the tourist corresponding to the code of the image information is found. After the tourist corresponding to the code of the image information is found, the tourist position is fed back to the display module for display, so that the lost tourist can be quickly found; during this period, if there is no photo of the lost person among the other people in the same row, the operator can call out the image information of the lost tourist from the database module through the calling module, and call out the corresponding code, so as to patrol the unmanned aerial vehicle 76 through the control module;

[0100] After finding the lost tourist, the staff controls the patrol module to stop working. At this time, the patrol unmanned aerial vehicle 76 flies back and resets to the bottom plate 71. The control module controls the motor 753 to work, so that the output shaft of the motor 753 reversely rotates, and the free ends of the two top covers 74 are attached to each other. The sealing area is formed by the two top covers 74 and the bottom plate 71 to seal and protect the patrol unmanned aerial vehicle 76. During this period, the two sealing gaskets 742 abut each other, and the two sealing gaskets 742 abut the bottom plate 71, thereby increasing the sealing property of the sealing area. After the free ends of the two top covers 74 are attached to each other, the control module controls the two driving rods four 8 to move the mounting plate 81 upward, drives the charging head 82 to move upward and butt with the charging seat 762, thereby achieving the effect of charging the storage battery in the battery shell 761, and achieving the purpose of ensuring power supply for the patrol unmanned aerial vehicle 76 and the face recognition camera two 763;

[0101] When the sign 64 needs to be replaced, the staff uses a tool to disassemble the bolt 62 located near the insertion slot 63, so that the positioning of the sign 64 is cancelled, the sign 64 can be disassembled, after disassembly, one end of the sign 64 near the clearance hole 641 is inserted into the two insertion slots 63, and then the bolt 62 penetrates through the clearance hole 641 and is fixed between the two positioning rings 61, so that the sign 64 can be fixed, thereby completing the replacement of the sign 64;

[0102] When the bottom plate 71 and the parts are maintained, the personnel rotates the worm 724 to drive the worm wheel 723 to rotate the two articulated shafts II, and the two straight gears 722 are driven to rotate the two articulated shafts II in opposite directions, so that the two positioning clamping plates 721 rotate in opposite directions around the two articulated shafts II, and the two positioning clamping plates 721 are away from each other to cancel the clamping of the supporting rod 41, so that the bottom plate 71 can be disassembled, thereby facilitating the maintenance of the parts on the bottom plate 71. After the maintenance is completed, the personnel positions the two positioning clamping plates 721 above the plurality of face recognition cameras 43 and sleeved outside the supporting rod 41, and reversely rotates the worm 724 to drive the two positioning clamping plates 721 to rotate in opposite directions around the two articulated shafts II, so that the two positioning clamping plates 721 are in contact with the supporting rod 41, and the two positioning clamping plates 721 and the supporting rod 41 are fixed, the position of the bottom plate 71 is positioned, and the installation of the bottom plate 71 is completed.
