International Classification:

G06F 1546

US Classification:

364513

Abstract:

The video image of the end effector (26) and work surface (32) in the vicinity of the end effector is converted into a series of continually generated digitized images (132), which are further processed to detect and track the relative motion between the end effector and the work surface. After calibration (126), whereby an index of coordinates and arm orientation is established for a known positioning of the end effector relative to a known reference feature (28a) on the work surface, the tracking (168) of the motion of the end effector is utilized to continually update the index (104) to indicate the actual coordinate and orientation of the end effector relative to the work surface. The updated index is displayed on a live video monitor (44), and can be used as input to the feedback circuit (94) of the manipulator control system. In another embodiment of the invention, a high resolution monitor (52) displays an image of substantially the entire work surface, and particularly the features of interest, in the nature of a work surface map, and superimposes thereon a visual indication of the location, orientation and movement of the end effector, using the updated index information.

Abstract:

A system and method for reading a barcode displayed on an object is provided. The system includes a barcode reader having a plurality of cameras communicatively coupled to an image processor, and a controller device communicatively coupled to the plurality of cameras and the image processor. The cameras are arranged to define a first opening therebetween sized to receive the object therein. The controller device triggers an operation of each camera. Each camera is operative to capture a respective image of a different corresponding portion of the surface of the object, and to send the respective image to the image processor. The image processor is configured to combine the respective images received from each camera into a composite image, and to read a barcode from the composite image.

Abstract:

A system for isolating signals from individual vehicles. An array of sensors generates a plurality of time records. The time records are transformed into spectrogram structures, and for each time-frequency point in the spectrogram structures, a bearing is calculated, to form a movement structure. A Hough transform is used to fit a movement model to the movement structure, to form a Hough transform structure. Peaks in the Hough transform structure correspond to vehicles and their position in the Hough transform structure correspond to motion parameters, such as the velocity of the vehicle, and the time of closest approach of the vehicle to the array of acoustic sensors. A model of the motion of a vehicle is then used to associate, with the vehicle, points (e.g., structure elements in the spectrogram structures) from the data.

Abstract:

A system for locating the position of a component includes, an image capture device, the image capture device being configured to capture an image of a component, a working implement mounted in fixed relation to the image capture device, a positioning system configured to adjust a position of the image capture device and the working implement in relation to the component, and an image processing module in communication with the image capture device, the imaging processing module being configured to receive the image from the image capture device and to identify at least one feature of the component. The positioning system is configured to adjust the position of the image capture device based on a location of the identified feature within the image to align the image capture device with the identified feature, and to align the working implement with the identified feature based upon an offset between the image capture device and the working implement.
