The present disclosure provides a method of determining a distance and a height, including: measuring, a first distance, a second distance and a third distance from the security inspection device to the tested person as well as measuring a first height, a second height and a third height of the tested person; determining, a relationship between the first distance and a minimum distance threshold as well as a maximum distance threshold, a relationship between the second distance and the minimum distance threshold as well as the maximum distance threshold, and a relationship between the third distance and the minimum distance threshold as well as the maximum distance threshold; determining, a final distance from the security inspection device to the tested person and a final height of the tested person; and performing a pixel conversion and a size conversion on the pupil image of the tested person.

Method and device of determining distance and height based on a plurality of sensors

An embodiment of the present disclosure discloses a wireless charging device comprising a wireless receiving module, a controller, a first charging module, and a second charging module. The wireless receiving module is configured to receive a wireless charging signal in response to the wireless charging device being in a wireless sensing area, transmit a state indication signal to the controller, receive a charging indication signal from the controller, and determine whether to transmit the wireless charging signal to the first charging module according to the charging indication signal. The controller is configured to transmit the charging indication signal to the wireless receiving module according to the state indication signal, and in response to the charging indication signal instructing the wireless receiving module to transmit the wireless charging signal, output a control signal to the first charging module to control the first charging module to receive the wireless charging signal, charge the second charging module, and output an electrical signal. The first charging module is configured to, in response to receiving the control signal, receive the wireless charging signal, charge the second charging module, and output the electrical signal.

Wireless charging device, the method thereof and security device including wireless charging device

The present disclosure provides a method of remotely measuring a size of a pupil, including: acquiring an image of a to-be-measured person by using a detection device; acquiring an image of a pupil of the to-be-measured person from the image of the to-be-measured person; measuring a distance between the to-be-measured person and the detection device by using the detection device; and calculating an actual size of the pupil of the to-be-measured person based on the measured distance and the image of the pupil of the to-be-measured person. The present disclosure further provides an apparatus for remotely measuring a size of a pupil, an electronic device, and a non-transitory computer-readable medium.

Apparatus and method of remotely measuring size of pupil

The present disclosure provides an intelligent lock. In an embodiment, the intelligent lock includes: a lock body having a lock hole; a lock lever, the lock lever being capable of being plugged into and being unplugged out of the lock hole of the lock body; a first restricting member movably provided inside the lock body, and capable of being moved and latched into the lock hole to restrict the plugging of the lock lever into the lock hole or the unplugging of the lock lever out of the lock hole; a second restricting member movably provided inside the lock body, and capable of being abutted against the first restricting member so as to restrict a movement of the first restricting member; a detecting device provided in the lock body, and configured to detect the plugging operation of the lock lever into the lock hole or the unplugging operation of the lock lever out of the lock hole and to send a detection signal; and a main control element communicatively connected to the detecting device, and configured to determine a locking state of the intelligent lock in accordance with the detection signal sent by the detecting device.

Intelligent lock

A security inspection system and a security inspection method are disclosed. The system includes: at least one inspection sub-system configured to perform ray scanning on an object to be inspected; at least one on-site image processing computer communicatively connected to the at least one inspection sub-system, and configured to store and process a radiographic image in real time; and at least one remote image processing computer communicatively connected to the at least one on-site image processing computer via at least one of a public network and a dedicated network. The at least one remote image processing computer each is configured to log in one of the at least one on-site image processing computer through remote access to synchronize remote data on a screen of the on-site image processing computer to the remote image processing computer.

Security inspection system and method

The present application relates to a method of assisting analysis of a radiation image and a system using the same, which belongs to the field of image processing. A method of assisting analysis of a radiation image includes: acquiring a radiation image to be analyzed; acquiring customs declaration information of the radiation image to be analyzed; acquiring a feature-matched historical image from a typical image library according to the radiation image to be analyzed; and/or acquiring a standard image and/or detailed customs declaration information of the standard image according to the customs declaration information of the radiation image to be analyzed. The method of assisting analysis of a radiation image and the system using the same may assist an image inspection person to judge whether or not the current radiation image carries violation items, whether or not a concealing or missing report occurs and so on.

Method of assisting analysis of radiation image and system using the same

The present disclosure provides a radiation image inspection system based on B/S architecture. The system comprises: at least one client terminal, configured to initiate an image operation request to a Web server, and display an image operation result on a browser of the client terminal upon receiving a response from the Web server; an image processing assembly, configured to query, based on the image operation request from the client terminal and forwarded by the Web server, an image which the client terminal desires to process, perform an operation on an image as requested by the client terminal, convert the resulted image into an image in a designated format and quality and return the converted image to the browser of the client terminal via the Web server for displaying; and the Web server, configured to receive the image operation request from the client terminal, forward the image operation request to the image processing assembly, and return the image operation result from the image processing assembly to the client terminal.

Radiation image inspection system and method based on B/S architecture

A system and method for customs inspection and release are disclosed. In one aspect, a system includes a device layer of devices for inspection and release, at least some of which generate subject detection data. The system also includes an adaptor layer of adaptors corresponding to the devices that receive detection data from its corresponding device and convert it into an event in a formatted message. The system also includes a message service layer including a bus that receives events from the adaptor layer and constructs event messages based on them. The system also includes a processing control layer that receives and processes event messages, generates instructions associated with them, and transmits the instructions to the message service layer, which constructs instruction messages based on the received instructions and transmits them to the adaptor layer. The adaptor layer converts them into device instructions that operate based on them.
