The field of the disclosure relates generally to navigational charts, and more specifically, to systems used to report objects of interest to be included in navigational charts.
For vehicles operating in, or on, a body of water, such as a boat, a chart plotter may be used to display one or more navigational charts. The displayed charts assist a user in navigating the vehicle through the body of water. At least some known charts indicate the location of one or more objects of interest. For example, if the object of interest is an obstacle, the user can use the navigational chart to avoid the obstacle.
However, at least some objects of interest may not be included in a displayed chart, or may be indicated in inaccurate locations. For example, an older chart may not include an object of interest that appeared more recently. Further, some objects of interest may move over time. Moreover, some objects of interest may not be included in a chart simply because they were previously unknown to exist.
Accordingly, users may report an object of interest so that the object may be included in a new or updated navigational chart. However, in at least some known reporting systems, the user reports an object by calling a human operator and describing the object, and/or by composing and sending an email that describes the object. Such a process may be relatively time-consuming for the user, and accordingly, the user may decide it is not worth the time or effort to report the object. Further, in at least some known reporting systems, the only information collected regarding the object is a coordinate location of the object, thus making it difficult to verify the existence of the object.
In one aspect, a computing device is provided. The computing device includes a user interface configured to receive an input that indicates a user has detected an object of interest in a body of water, a processing device coupled to the user interface, the processing device configured to automatically retrieve, in response to the input, data from at least one data source, and generate a report including the retrieved data, and a means for transferring data coupled to the processing device and configured to transmit the generated report to a database that includes a plurality of navigational charts, wherein the generated report is used to update at least one of the database and at least one of the plurality of navigational charts to include the object of interest.
In another aspect, a system for reporting an object of interest is provided. The system includes at least one data source, a computing device communicatively coupled to the at least one data source, the computing device configured to automatically retrieve, in response to an input that indicates a user has detected the object of interest in a body of water, data from said at least one data source, and generate a report including the retrieved data, and a database including a plurality of navigational charts updatable, using the generated report, to include the object of interest.
In yet another aspect, a method for reporting an object of interest is provided. The method includes receiving, at a processing device, an indication that a user has detected an object of interest in a body of water, automatically retrieving, in response to the indication, data from at least one data source, generating, using the processing device, a report including the retrieved data, and updating, using the generated report, at least one of a database and a navigational chart to include the object of interest.
The features, functions, and advantages that have been discussed can be achieved independently in various implementations or may be combined in yet other implementations, further details of which can be seen with reference to the following description and drawings.
The systems and methods described herein enable reporting an object of interest such that navigational charts may be updated to include the object of interest in a timely and efficient manner. In the exemplary implementation, a chart plotter receives an indication from a user that an object of interest has been detected, and in response, the chart plotter retrieves data from one or more data sources to generate a report including that data. The report can be used to update navigational charts to include the object of interest.
Technical effects of the methods and systems described herein include at least one of: (a) receiving an indication that a user has detected an object of interest in a body of water; (b) automatically retrieving, in response to the indication, data from at least one data source; (c) generating a report including the retrieved data; (d) transmitting the generated report to a database; and (e) updating at least one navigational chart in the database to include the object of interest.
Processor 115 may include one or more processing units (e.g., in a multi-core configuration). Further, processor 115 may be implemented using one or more heterogeneous processor systems in which a main processor is present with secondary processors on a single chip. In another illustrative example, processor 115 may be a symmetric multi-processor system containing multiple processors of the same type. Further, processor 115 may be implemented using any suitable programmable circuit including one or more systems and microcontrollers, microprocessors, reduced instruction set circuits (RISC), application specific integrated circuits (ASIC), programmable logic circuits, field programmable gate arrays (FPGA), and any other circuit capable of executing the functions described herein. In the exemplary implementation, processor 115 generates a report that identifies an object of interest, as described herein.
In the exemplary implementation, memory device 110 is one or more devices that enable information such as executable instructions and/or other data to be stored and retrieved. Memory device 110 may include one or more computer readable media, such as, without limitation, dynamic random access memory (DRAM), static random access memory (SRAM), a solid state disk, and/or a hard disk. Memory device 110 may be configured to store, without limitation, application source code, application object code, source code portions of interest, object code portions of interest, configuration data, execution events and/or any other type of data.
In the exemplary implementation, chart plotter 100 includes a presentation interface 120 that is coupled to processor 115. Presentation interface 120 presents information, such as navigational charts, to a user 125. For example, presentation interface 120 may include a display adapter (not shown) that may be coupled to a display device, such as a cathode ray tube (CRT), a liquid crystal display (LCD), an organic LED (OLED) display, and/or an “electronic ink” display. In some implementations, presentation interface 120 includes one or more display devices.
In the exemplary implementation, chart plotter 100 includes a user input interface 135. User input interface 135 is coupled to processor 115 and receives input from user 125. User input interface 135 may include, for example, a keyboard, a pointing device, a mouse, a stylus, a touch sensitive panel (e.g., a touch pad or a touch screen), a gyroscope, an accelerometer, a position detector, and/or an audio user input interface. A single component, such as a touch screen, may function as both a display device of presentation interface 120 and user input interface 135.
Chart plotter 100, in the exemplary implementation, includes a communication interface 140 coupled to processor 115. Communication interface 140 communicates with one or more remote devices. To communicate with remote devices, communication interface 140 may include, for example, a wired network adapter, a wireless network adapter, and/or a mobile telecommunications adapter.
In the exemplary implementation, chart plotter 100 is onboard a vehicle (not shown) operating in, or on, a body of water, such as a boat. The body of water may any type of body of water (e.g., a lake, river, ocean, etc.). Chart plotter 100 displays one or more navigational charts on presentation interface 120 (shown in
To assist in navigation, charts displayed on chart plotter 100 may include one or more objects of interest. For example, a chart may indicate the location of an obstacle in the body of water. By observing the obstacle on the displayed chart, user 125 can operate the vehicle to avoid the obstacle. In another example, the object of interest could be a shipwreck, and using chart plotter 100, scuba divers could locate the shipwreck.
As used herein, an object of interest may include any feature, item, and/or landmark that could be displayed or otherwise indicated on a navigational chart. For example, an object of interest could include a rock formation, a tree stump, a shipwreck, debris, a cargo container, or a sandbar. The object of interest could be located on the surface of a body of water or at least partially submerged in the body of water.
At least some objects of interest may not be included in a displayed chart, or may be indicated in inaccurate locations. For example, if a cargo container fell off a barge and settled at the bottom of a river after the latest version of a chart was released, the cargo container would not be included in the chart. Further, some objects of interest, such as sandbars, may move over time, making older charts outdated. Moreover, some objects of interest may have existed at the time the chart was created, but simply may not have been discovered to be included in the chart. Accordingly, when user 125 observes an object of interest, visually or with the assistance of instrumentation, that is missing or that is shown in the wrong location on a chart, system 200 enables user 125 to report the object of interest, such that the reported object of interest can be included in new or updated charts in an efficient manner.
In the exemplary implementation, chart plotter 100, and more specifically, processor 115 (shown in
In the exemplary implementation, the report includes configuration data associated with the chart plotter 100. For example, such configuration data may include a device identification number (e.g., serial number) of chart plotter 100 and/or a chart code that identifies a chart corresponding to the location of the object (i.e., identifies the chart covering the area where the object of interest is located). The chart code also indicates the release date of the chart (i.e., a time stamp indicating how old the chart is). The device identification number and chart code may be stored in, for example, memory device 110.
The report also includes transducer data from depth transducer 214 in the exemplary implementation. Transducer data may include, for example, a depth value of the object recorded using depth transducer 214, and/or a screenshot of a data page from depth transducer 214.
In the exemplary implementation, the report also includes navigation data from navigation system 216. Navigation system 216 may be integrated into the vehicle on which chart plotter 100 is operated. Navigation data may include, for example, a coordinate location (e.g., latitude and longitude) of the object of interest, the date the object was located, the time the object was located, a speed over ground (SOG) of the vehicle when the object was located, and a course over ground (COG) when the object was located. Notably, the specific types of data listed herein for inclusion in the report are merely exemplary. In other implementations, the report may include any set of data that facilitates identifying and locating an object of interest.
In the exemplary implementation, chart plotter 100 is coupled to data sources 210 via communication interface 140 (shown in
In the exemplary implementation, chart plotter 100 automatically retrieves data from data sources 210 in response to a user input using, for example, user input interface 135 (shown in
The report generated by chart plotter 100 is provided to database 204. In the exemplary implementation, the generated report is encrypted and stored as a file on a memory card 230. In at least some implementations, memory card 230 functions as memory device 110. Memory card 230 may include, for example a secure digital (SD) card or a universal serial bus (USB) storage device. Using memory card 230, user 125 can upload the generated report file to database 204 over a wired or wireless network, or provide memory card 230 to a human operator responsible for managing database 204.
Alternatively, the report may be supplied to database 204 using any other suitable transmission means. For example, using communication interface 140, chart plotter 100 may transmit the generated report directly to database 204 over any suitable communication means, including wired or wireless networks. Further, the report may be automatically transmitted upon communication interface 140 establishing a communications link with database 204, or in response to a user input. As used herein, transmitting the report to database 204 includes using memory sticks, memory cards, a wired network, a wireless network, and/or any other suitable means to transfer data from chart plotter 100 to database 204.
In the exemplary implementation, a human operator determines whether charts 206 stored in database 204 should be updated to include the reported object of interest. For example, to verify the accuracy of a reported object of interest, charts 206 may only be updated after two or more reports identifying the object of interest are received. Further, the data in reports may be indicative of the accuracy of the report. For example, if a report indicates that an object of interest was located while the vehicle was travelling at a relatively high speed over ground, data obtained by depth transducer 214 in the same report may be inaccurate. Alternatively, the report supplied from chart plotter 100 may be used to automatically update pertinent charts 206 in database 204.
In at least some implementations, the report is stored in an additional database (not shown). The report may be downloaded from the additional database to chart plotter 100 as value added data such that the object of interest in the report is included in charts displayed on chart plotter 100. In one implementation, user 125 can select, using user input interface 135, whether or not to display the value added data on chart plotter 100 (i.e., turn display of the value added data on and off). Once the report is used to update database 204 and/or charts 206, the report may be removed from the intermediate database.
Charts 206 stored in database 204 and updated with objects of interest from one or more reports may be used in a variety of applications. For example, charts 206 may be provided to user 125 as updates for chart plotter 100. Charts 206 may be used for marine navigation including, for example, leisure sailing, fishing, and/or finding locations of interest for scuba diving/snorkeling. Further charts 206 may be used in software applications for mobile devices (e.g., smart phones, tablets) and geographic information systems implemented using a computing device. In at least some embodiments, database 204 is updated from the reports, and database 204 itself is provided to customers (e.g., user 125). Further, in some implementations, a generated report could be provided to multiple databases 204 each including different sets of charts 206.
In some implementations, to incentivize user 125 to report objects of interest, user 125 may receive a reward in exchange for supplying a report to database 204. For example, user 125 may receive an updated chart including the reported object for free or at a discounted rate.
The implementations described herein enable an object of interest to be easily reported such that navigational charts may be updated to include the object of interest. When a chart plotter receives an indication from a user that an object of interest has been detected, the chart plotter automatically retrieves data from one or more data sources and generates a report that includes the new data. The report can be used to update navigational charts to include the object of interest.
Unlike at least some known reporting systems that require a user to interface with an operator and/or send an email, the systems and methods described herein enable data to be collected and reported easily such that a report may be generated that identifies an object of interest with relatively little user input.
Further, as compared to at least some known reporting systems, in which only coordinates of the object of interest are reported, in the systems and methods described herein, the report includes additional data that assists in locating and identifying the object.
The implementations described herein may utilize executable instructions embodied in a computer readable medium, including, without limitation, a storage device or a memory area of a computing device. Such instructions, when executed by one or more processors, cause the processor(s) to perform at least a portion of the methods described herein. As used herein, a “storage device” is a tangible article, such as a hard drive, a solid state memory device, and/or an optical disk that is operable to store data.
Although specific features of various implementations of the invention may be shown in some drawings and not in others, this is for convenience only. In accordance with the principles of the invention, any feature of a drawing may be referenced and/or claimed in combination with any feature of any other drawing.
This written description uses examples to disclose various implementations, which include the best mode, to enable any person skilled in the art to practice those implementations, including making and using any devices or systems and performing any incorporated methods. The patentable scope is defined by the claims, and may include other examples that occur to those skilled in the art. Such other examples are intended to be within the scope of the claims if they have structural elements that do not differ from the literal language of the claims, or if they include equivalent structural elements with insubstantial differences from the literal languages of the claims.
