System and method for servoing robots based upon workpieces with fiducial marks using machine vision

A system and method for servoing robot marks using fiducial marks and machine vision provides a machine vision system having a machine vision search tool that is adapted to register a pattern, namely a trained fiducial mark, that is transformed by at least two translational degrees and at least one mon-translational degree of freedom. The fiducial is provided to workpiece carried by an end effector of a robot operating within a work area. When the workpiece enters an area of interest within a field of view of a camera of the machine vision system, the fiducial is recognized by the tool based upon a previously trained and calibrated stored image within the tool. The location of the work-piece is derived by the machine vision system based upon the viewed location of the fiducial. The location of the found fiducial is compared with that of a desired location for the fiducial. The desired location can be based upon a standard or desired position of the workpiece. If a difference between location of the found fiducial and the desired location exists, the difference is calculated with respect to each of the translational axes and the rotation. The difference can then be further transformed into robot-based coordinates to the robot controller, and workpiece movement is adjusted based upon the difference. Fiducial location and adjustment continues until the workpiece is located the desired position with minimum error.

Emergency communications for the mobile environment

Systems and methods for two-way, interactive communication regarding emergency notifications and responses for mobile environments are disclosed. In accordance with one embodiment of the present invention, a specific geographic area is designated for selective emergency communications. The emergency communications may comprise text, audio, video, and other types of data. The emergency notification is sent to users' mobile communications devices such as in-vehicle telematics units, cellular phones, personal digital assistants (PDAs), laptops, etc. that are currently located in the designated area. The sender of the emergency message or the users' service provider(s) may remotely control cameras and microphones associated with the users' mobile communications devices. For example, a rear camera ordinarily used when driving in reverse may be used to capture images and video that may assist authorities in searching for a suspect. The users' vehicles may send photographs or video streams of nearby individuals, cars and license plates, along with real-time location information, in response to the emergency notification. Image recognition algorithms may be used to analyze license plates, vehicles, and faces captured by the users' cameras and determine whether they match a suspect's description. Advantageously, the present invention utilizes dormant resources in a highly beneficial and time-saving manner that increases public safety and national security.
