摘要:
Monitoring technique includes identifying objects in images and associating color characteristics with each identified object. When the color characteristics of an object in one image is above a color resemblance threshold to the color characteristics of an object in another image, the object in both images is considered the same. Otherwise, the respective object in both images are considered to be different. Data about time that each image including an identified object was obtained and location of each object when each image including an identified object was obtained is derived. An information conveyance system is activated to convey the time and location-related data about identified objects relative to defined areas of the site or movement of the identified objects or people into, between or out of the defined areas of the site or a communication resulting from such data satisfying one or more conditions.

A location tracking system for building a geographic location database of network nodes in a computer network includes a trace engine module configured to send trace Id commands to a plurality of user terminals. The user terminals are actively coupled to a server node so that the trace engine module is able to obtain IP address of each of the user terminals and its corresponding geographic location. A first database is configured to store IP addresses obtained by the trace engine module and their corresponding geographical locations. A second database is configured to store a set of physical connections between IP addresses obtained by the trace engine module. The system can then determine the geographical location of end user terminals who employ the database as previously populated.

System for enabling a wireless computing device to determine its position includes a server with a database of identification and positional information about wireless beacons and a wireless computing device arranged to wirelessly communicate using the Internet with the server. The server determines the geographic location of the wireless computing device upon receiving data from the wireless computing device relating to reception of signals by the wireless computing device from at least one wireless beacon and analysis of the signals in light of the information contained in the database of the server. The server applies a calculation algorithm which determines the geographic location of the wireless computing device upon input of identification and signal strength information about the wireless beacon(s) derived from the received signals.
摘要:
Method, system and computer program for generating a database of pixel patterns includes obtaining images using an imaging system of mobile devices, each image including a pixel pattern, and determining a position of the mobile device using a positioning system at least partly situated on the mobile device when each image is obtained using the imaging system of the mobile device. Positional relationships between a size and/or angular orientation of the pattern of pixels and an associated determined position of the mobile device when the at least one image including the pattern of pixels was obtained are generated and enables retrieval of an estimation of the position of the mobile device upon input of another image including the pattern of pixels. The generated positional relationships between the size and/or angular orientation of the pattern of pixels and the associated determined position of the mobile device are stored in a database.
摘要:
Method for determining position of a mobile device having an imaging device includes obtaining an image of a mark on a known-position object from the imaging device, the mark having an encoded position, decoding the mark to derive data about the position of the mark using a database of marks and their positions, and analyzing appearance of the mark in the image in combination with the derived data about the position of the mark to derive the position of the mobile device. Mark appearance analysis may involve analyzing an angle between an imaging direction of the imaging device and a surface of the mark.
摘要:
System and method for controlling access to information about or from computing devices in which an authorization request to enable a first one of the devices to obtain information from or about a second one of the devices is generated and directed to the second device with a token assigned to the first device. Once the token is received by the second device, the authorization request is presented to its user in a form enabling viewing and manually entry of the token into the second device. The user of the first device can, when desired, request information from or about the second device. The request is fulfilled and the information from or about the second device is provided to the first device only after the user of the second device has manually entered the token assigned to the first device.

摘要:
Method for providing position-based information to a mobile device with at least one imaging device includes obtaining, using the imaging device, an image including a stationary pattern of pixels, searching through a database of pixel patterns for a pixel pattern that most closely matches the pattern of pixels in the obtained at least one image, the database containing pixel patterns and positional information about the pixel patterns, and retrieving from the database as a result of the searching, positional information about one of the pixel patterns that is deemed to most closely match the pattern of pixels in the obtained at least one image. Data is provided to the mobile device, i.e., to a data output device or functionality thereof, dependent on the retrieved positional information about one of the pixel patterns that is deemed to most closely match the pattern of pixels in the obtained at least one image.
摘要:
Method includes maintaining a collaborative database on a database server containing geographic location information pertaining to Wi-Fi access points. The collaborative database includes database records for Wi-Fi access points including a MAC address and geographic location. A position location request from a Wi-Fi enabled wireless device is received at a server, and includes a respective MAC address of at least one Wi-Fi access point for which a wireless beacon is detected by the wireless device. Via a query issued to the database server using at least one MAC address included in the position location request, geographic location data for one or more Wi-Fi access points is retrieved from the database. A processor determines geographic location of the wireless device based at least on the retrieved geographic location data, and returns, via the server, geographic location data to the wireless device corresponding to the geographic location of the wireless device.
