摘要： A system and method that detects and identifies an event from a sequence of images received. The system comprises a control unit that receives and processes the sequence of images from the camera. The control unit identifies at least one stationary image prior to the event and one stationary image subsequent to the event. The control unit compares one or more representations corresponding to one or more edges in the first stationary image with one or more representations corresponding to one or more edges in the second stationary image to determine whether an object has been deposited or removed during the event.

摘要： A device for identifying vehicles traveling in excess of a predetermined speed. The device including: speed measurement detector for measuring the speed of a target vehicle and outputting a signal indicative of the measured speed; a camera operatively connected to the speed measurement detector for capturing image data of a license plate affixed to the target vehicle when the target vehicle exceeds the predetermined speed; and a device for tagging the captured image data with the signal indicative of the measured speed of the target vehicle. The device can further have a recognition system for recognizing the license plate of the target vehicle which controls the camera to provide an enhanced view of the license plate. The device can also have classification and color identification systems for identifying a type and color of the target vehicle. The type and color information can also be tagged to the image data.

摘要： The position of a target lying on a plane is indicated by inputting a pointing direction which is computationally projected onto a plane. If the target is known to lie on a contour, the position is specified unambiguously. Alternatively, the position of a target can be specified by inputting its axial coordinates in successive steps. In another alternative approach, the image containing the target is translated and/or rotated and the target indicated again. The two direction projections are then used to determine the position of the target in 2-space. The direction indications may be input by a camera or other method, such as one or more radio transmitters.

摘要： The present invention relates to a device containing an automatic zoom lens, and more particularly to a zoom lens that is controlled by a processor that is linked to a gaze tracking system. As a user looks onto an object through the device, the gaze tracking system collects data relating to the position of each eye of the user. This eye position data is input into the processor where the focal point of the user is determined. The processor then adjusts the zoom lens to zoom in or out onto the object based on either a predetermined or user input zoom factor.

摘要： Targets associated with transactions to be processed at a workstation are read by capturing return light from the targets with an array of light sensors of a solid-state imager having a field of view that extends through a workstation window to the targets. A controller controls the imager to operate at a frame rate to acquire images of the targets over successive frames in either a batch mode or a free-running mode. A memory stores the acquired images. The controller processes all of the stored images, and processes at least one of the stored images over an extended time period greater than one of the frames.

摘要： An operator is guided to move an imaging reader to an optimum reading position in which to read a symbol by image capture. Optimum image capture occurs substantially at an imaging plane of an imaging assembly, and the operator is visually guided so that the symbol is located substantially at the imaging plane in a working range of distances.
