A mobile terminal (200) obtains image data related to a product posted on a flier (300) by imaging and sends the image data related to the product to a shopping management server (100). Upon reception of the image data related to the product from the mobile terminal (200), the shopping management server (100) determines the product by analyzing the image data related to the product, obtains at least one of inventory information and sales information of the product, and sends at least one of the inventory information and the sales information of the product to the mobile terminal (200). The mobile terminal (200) combines computer-graphics image data indicating at least one of the inventory information and the sales information of the product sent from the shopping management server (100) with an image of the flier in real space and presents the combined image, thereby solving the problem.

An automatic timing measurement system that provides a measure of time of passage of a watercraft through a prescribed course. Algorithms based on inertial or other estimates augmented by GPS speed / position measurements are used to track position of a watercraft. Said position estimates are used to allow the locations of prescribed courses to be mapped and memorized. Algorithms are then used to allow the apparatus to automatically detect passage of a watercraft through mapped courses for the purpose of measuring and reporting time of passage of said watercraft past key points in said course, and for modifying the behavior of the speed control portion of the apparatus if necessary at certain points in the mapped course. A measure of accuracy of driver steering can be provided along with the ability to automatically steer the watercraft through the course if “steer-by-wire” mechanism is available. GPS speed control is augmented with a secondary velocity measurement device that measures speed over water resulting in an optional user selectable real-time compensation for water current. Furthermore, GPS is used as the key input to produce boat speed-based pull-up profiles.

Many different types of systems are utilized or tasks are performed in a marine environment. The present invention provides various configurations of unmanned vehicles, or drones, that can be operated and / or controlled for such systems or tasks. One or more unmanned vehicles can be integrated with a dedicated marine electronic device of a marine vessel for autonomous control and operation. Additionally or alternatively, the unmanned vehicle can be manually remote operated during use in the marine environment. Such unmanned vehicles can be utilized in many different marine environment systems or tasks, including, for example, navigation, sonar, radar, search and rescue, video streaming, alert functionality, among many others. However, as contemplated by the present invention, the marine environment provides many unique challenges that may be accounted for with operation and control of an unmanned vehicle.

There is provided a navigation route generation device with which a host moving body can be navigated by offsetting it parallel to a line on the current travel direction of the host moving body by a simple operation, without changing the preset destination or bearing. A plotter that is part of an automatic steering system of a ship comprises a current route acquisition component, a parallel route generator, and a navigation route setting component. The current route acquisition component acquires the travel direction of the host ship. The parallel route generator generates a parallel route, which is a route that is parallel to the travel direction acquired by the current route acquisition component. The navigation route setting component sets the parallel route generated by the parallel route generator to the navigation route of the host ship.

Systems and methods disclosed herein provide for various embodiments of maritime control components. For example in one embodiment, a control component, adapted to be used with a watercraft, includes a mounting feature adapted to mount the control component to a steering wheel of the watercraft, and a mode selector of the control component adapted to receive and transmit a first user input signal corresponding to a user selected mode of operation from a plurality of selectable modes of operation including a map mode, a sonar mode, a fishfinder mode, a radar mode, an autopilot pattern mode, an entertainment mode, and / or a maritime mode. The control component further includes an increase / decrease actuator adapted to receive and transmit a second user input signal corresponding to a user selection within the user selected mode of operation. Embodiments of a watercraft and a method of display control are also provided.

The positions and motions of a bow and a stern of the ship are detected using redundant devices and evaluated to automatically perform difficult maneuvers in ports or to generate recommendations for controlling the ship

The invention provides an automatic ship collision avoidance method based on a velocity vector coordinate system. The automatic ship collision avoidance method comprises the steps of: (1) regarding a ship as a particle, and acquiring information of obstacles surrounding the ship; (2) judging whether a risk of collision between the ship and the surrounding obstacles exists through a collision prediction model, if the risk exists then entering the step (3), and if not then returning to the step (1); (3) calculating a relative velocity, at which the ship can move out from a collision region, of the ship in the velocity vector coordinate system, and calculating an absolute velocity of the ship according to the relative velocity; (4), regulating a course of the ship via an autopilot controller by utilizing the absolute velocity of the ship until the current velocity of the ship is the absolute velocity; (5) and repeating the steps from step (1) to step (4) over and over again so as to achieve automatic ship collision avoidance based on the velocity vector coordinate system. The automatic ship collision avoidance method can judge whether the risk of collision among ships exists and can provide the collision avoidance method.

A watercraft includes a plurality of devices, a central controller, and a display device. The central controller is programmed to execute centralized control of the devices. The display device includes a touch panel function. The display device is configured to communicate with the central controller, and to display information regarding watercraft in a Graphical User Interface (GUI) format.

The traffic control method according to the present invention includes obtaining radar information on a target from at least one radar; obtaining AIS information of the target from an AIS (automatic identification system) of the target; detecting GPS jamming; and fusing the radar information and the AIS information. The fusing selectively fuses the AIS information depending on whether the GPS jamming occurs in the position of the target as a result of the detection.

The invention relates to an underwater side-scan sonar collecting and releasing device arranged under a boat bow deck. The device is characterized in that the boat bow is provided with a slot so as to be convenient for arranging the sonar on the boat bow, the slot can also be used for collecting an underwater sonar, and after the sonar is collected, the sonar can be covered; the sonar is arranged on a collecting and releasing rod, and the collecting and releasing rod is driven through a transmission device comprising an electromotor, a speed reducer, a stainless steel chain, and the like to rotate so as to send the sonar into water; after the sonar reaches a boat bow working position vertical to the bottom of the boat, an electrical push rod pushes a positioning pin to insert into a positioning hole so as to improve the rigidity of the sonar collecting and releasing rod; and the rotation angle of collecting and releasing the sonar is measured by an encoder connected to a rotation shaft. The imaging quality of the sonar arranging device is high, and the device can realize the quick collection and release of the underwater sonar; after the sonar is placed, the positioning pin is inserted, which can effectively guarantee the working precision of the sonar; the sonar can be guaranteed to be correctly collected and released through the encoder; and by integrating the three points, the detection precision of the sonar can be effectively and greatly improved, and the device is convenient to use.
