The invention discloses a method for identifying pushing action based on a two-dimensional planar camera and a system. The method includes acquiring video images containing persons, and dividing hand detecting areas; realizing binarization processing for divided hands, and acquiring corresponding contours of the hands; comparing the contours of a divided current hand with a standard hand contour set in advance, and judging whether push action of the hand is performed; determining that the pushing action of the hand is performed when contour similarity is larger than a set threshold value T, extracting the hand area of the hand performing the pushing action, extracting the center of the minimum rectangle surrounding the contour of the hand, and creating a historical movement graph; and identifying the pushing action of the hand for the built historical movement graph by the aid of orientation gradient vectors. The method is simple in algorithm and high in action identification rate, and simultaneously burden on users in terms of memory is reduced.

The invention relates to the technical field of data storage technologies and information security, in particular to a testament management system and method based on a block chain technology. The testament management system comprises a data driving layer, a business logic layer and an application layer, the data driving layer is used for providing the underlying technical support, the business logic layer is used for dividing the business scenes, and the application layer is used for providing the use interfaces. The testament management method is realized based on the testament management system. By the testament management system, the defects of a traditional testament management technology can be better overcome, and the data integrity of the testament customizing, storing, updating, verifying and other processes can be effectively guaranteed through the block chain technology.

A biological identity authentication and payment system based on hand vein identification and an identity authentication method are disclosed. A palm vein acquisition unit and a display interaction unit are included and are connected through a data line. The palm vein acquisition unit comprises a hand vein palm holding body, a lens module group, an image sensor, an infrared light emitting diode array, a light intensity sensor, a controller, a data storage unit, an encryption chip, and a communication interface which is connected with the display interaction unit. The electrical connection relationship of the palm vein acquisition unit is that the image sensor, the infrared light emitting diode array, the light intensity sensor, the data storage unit, the encryption chip, and the communication interface are connected with the corresponding interfaces of the controller respectively. The system and the method have advantages that a user only needs to register one-time hand vein information and bind a personal payment account to a hand vein identification biological identity authentication device for one time so that the binding of personal property account information and personal biological authentication information can be completed; and compared with other biological identification technology, the technology in the invention possesses high safety.

An adjustable flexible nasal endoscope belongs to the technical field of medical apparatus and instruments, and can solve the problem that the conventional nasal endoscopes are complex in structure and are poor in stability, hard nasal endoscopes cannot flex according to a natural cavity structure, expansion ball bags cannot perform expansion treatment in a visible situation and cannot directly perform washing and medicine changing in sinus cavities, and the application effect is poor. The adjustable flexible nasal endoscope includes a hand-held portion; a winding mechanism arranged on the back of the hand-held portion; a three-cavity flexible pipe passing through the hand-held portion and extending out from a front part, wherein a power channel, an optical fiber imaging channel, and an apparatus channel are arranged in the three-cavity flexible pipe in the length direction in parallel; a steel cap arranged on one end extending out of a front cover, of the three-cavity flexible pipe; a steel pipe sleeving the three-cavity flexible pipe, wherein one end of the steel pipe and the front end of the hand-held portion form a slide fit; a micro steel pipe arranged in a power channel of the three-cavity flexible pipe, wherein one end of the micro steel pipe is fixedly connected to a fixing block in a back cover, and the other end of the micro steel pipe is fixed on an end portion of the three-cavity flexible pipe; a steel wire arranged in the micro steel pipe, wherein one end of the steel wire is fixed on one end near the steel cap, of the micro steel pipe, and the other end of the steel wire extends out of the micro steel pipe and passes through the fixing block, and is connected to the winding mechanism through a guide wheel, and the working length of the steel wire can be changed through the winding mechanism.

The invention provides a network communication subject confirmation method. The method includes the steps that when a party A starts TCP connection to a party B, an SYN data package to be sent of the party A is intercepted, equal-length encryption is conducted on the SYN data package, and then the SYN data package is sent to the party B; after the party B receives the SYN data package, the SYN data package is decoded; when the party B sends an ACK data package to the party A, the ACK data package to be sent of the party B is intercepted, equal-length encryption is conducted on the ACK data package, and then the ACK data package is sent to the party A; after the party A receives the ACK data package, the ACK data package is decoded; when the party A sends the ACK data package to the party B, the ACK data package to be sent of the party A is intercepted, equal-length encryption is conducted on the ACK data package, and then the ACK data package is sent to the party B; after the party B receives the ACK data package, the ACK data package is decoded. By means of the network communication subject confirmation method, authentication and protection of the data packages are achieved at a handshake stage.

The invention discloses a vehicle parking management method, a device and a storage medium. The vehicle parking management method comprises the following steps of: identifying and acquiring of vehiclelicense plates and vehicle ownership marks when monitoring vehicle access to parking lots, comparing the identification of the ownership party of the vehicle with the ownership information of the prestored vehicle; determining a charging preference strategy of the vehicle according to the ownership information if the ownership identity of the vehicle is successfully compared with the owner's information of the prestored vehicle; and carrying out parking charging on the vehicle in combination with the charging preferential policy of the vehicle. The vehicle parking management method achieves the confirmation of the identification of the special vehicle, so that the special vehicle can automatically enjoy the corresponding parking preference and improve the parking management efficiency.

The invention provides a target guidance system and method for an unmanned aerial vehicle, the unmanned aerial vehicle and a storage medium. The system includes a wide-angle camera, a long-focus camera, and a processor. The wide-angle camera and the long-focus camera are fixedly installed on the unmanned aerial vehicle in a strapdown mode, the wide-angle camera and the long-focus camera are close to each other, optical axes of the wide-angle camera and the long-focus camera are parallel to each other, and the optical axes of the wide-angle camera and the long-focus camera and a longitudinal axis of a fuselage of the unmanned aerial vehicle keep fixed angles. The processor can search a plurality of suspected targets through appearance matching in a large range by detecting images shot by the wide-angle camera in real time, finish similarity sorting and optimal target screening, and can identify details of the optimal target in a small range to judge whether the target is a given target or not by detecting images shot by the long-focus camera in real time. Under the condition that the target is confirmed to be the given target, the unmanned aerial vehicle is guided to realize tracking flight of the given target by continuously calculating a wide-angle guide instruction. The system has the advantages of being simple in structure, stable, reliable and convenient to integrate.
