Abstract:
A DEVICE AND METHOD FOR A SURVEILLANCE SYSTEM UTILIZING A WIDE VIEW CAMERA A SERVES AS GUIDING SYSTEM TO DETERMINE THE AREA OF INTEREST I.E. THE AREA WHERE THE PRESENCE OR ABSENCE OF ACTIVITIES WITHIN THE AREA THAT IS BEING MONITORED, TOGETHER WITH A HIGH RESOLUTION CAMERA WHICH IS CONTROLLED IN PAN, TILT AND ZOOM WHICH PROVIDES A ZOOMED IMAGE OF THE AREA OF INTEREST.

Abstract:
A METHOD AND APPARATUS TO SETUP THREE DIMENSIONAL IMAGE CAPTURE AND PROCESSING IS DESCRIBED. A FIRST IMAGE (44) OF AN OBJECT OF INTEREST (22) AND A SECOND IMAGE (46) OF THE OBJECT OF INTEREST (22), WHICH HAS A DIFFERENT PERSPECTIVE FROM THE FIRST IMAGE (44), IS CAPTURED AT THE SAME TIME. BOTH THE IMAGES (44, 46) ARE INTERLACED, AND THE PARALLAX BETWEEN THE TWO RESULTANT IMAGES (44, 46) IS USED TO PRODUCE A THREE DIMENSIONAL RANGE DATA (50). THE THREE DIMENSIONAL RANGE DATA (50) REPRESENTS THE THREE DIMENSIONAL RANGE DATA OF THE OBJECT OF INTEREST (22). THE APPARATUS SETUP TO CAPTURE THREE DIMENSIONAL IMAGE ACCORDING TO THE PRESENT INVENTION COMPRISES OF A TILT-ABLE UPPER SENSOR (20) FOR CAPTURING A FIRST IMAGE (44) OF AN OBJECT OF INTEREST (22), A TILT-ABLE LOWER SENSOR (21) FOR CAPTURING A SECOND IMAGE (46) OF THE OBJECT OF INTEREST (22), AND A THREE DIMENSIONAL FORMATTER (48) TO COMBINE THE FIRST AND SECOND IMAGES (44, 46) INTO THREE DIMENSIONAL DATA. THE UPPER AND LOWER SENSORS (20, 21) ARE ALIGNED ON A COMMON VERTICAL AXIS, WHEREBY TWO DIFFERENT PERSPECTIVES OF IMAGES ARE DESIRED TO BE CAPTURED AT THE SAME TIME. FIG. 1
Abstract:
The present invention provides a method for generating multiple perspective views and providing multiple pan-tilt-zoom tracking based on an image captured having at least one object of interest as input, using a single camera comprising: an initialization routine 300 generally includes; generating 360° lookup tables; generating perspective view lookup table and perspective view and generating simplified 360° floor plan based on the input; a processing routine 310 generally includes performing object tracking and object pan-tilt- zoom (PTZ) tracking; selectively updating 360° corrected view and updating the perspective view; and a display routine 320 the output image obtained upon processed by the first two routines 300, 310 is wider and less blocked than that of the input image. A system thereof is also provided.
Abstract:
The present invention provides a method of processing sequence of image frames captured through an imaging device. The method comprises extracting feature points from a current frame of the sequence of the image frames; estimating disparity of the feature points; identifying an object from the current frame that occupies a large area of the current frame through the disparity of the feature points; matching feature points between the current image frame and a previous image frame to determine presence of a moving object; filtering out the matched feature points that correspond to the moving object to obtain matched feature points that correspond to background; estimating motion model based on the feature points that correspond to the background.
Abstract:
The present invention relates to a method for geometric transformation of video captured by a wide angle lens. The geometric transformation technique allows the restoration of the original view that has been captured by the lens. Accordingly, the method for geometric transformation of video images, comprises: capturing a scene (200) from a lens in a form of circular video image (210), decomposing (220) the circular video image (210) into arc image data (230), straightening and mapping (240) the decomposed lines (230) into straight vertical lines forming a rectangular image (250), and correcting the rectangular image using a non-linear stretching method in horizontal (260) and a non-linear stretching method vertical axes (280) to achieve a corrected rectangular image (300).
Abstract:
The invention provides for an imaging apparatus that uses a single camera and a single lens to capture a wide-angle view of an area while the camera is positioned in a bottom up position.
Abstract:
A system is provided for vehicle audit trail, where the vehicle audit trail system is fully automated to track the movements of the vehicle at any given time.
Abstract:
The present invention relates to apparatus and method for multiple-view panoramic imaging. According to one aspect of the present invention, the apparatus for multiple-view panoramic imaging includes a line-scan camera (107), a rotary stage (103), a capture plane (108), and a controller (111, 112) for each panoramic and multiple-view rotation. The apparatus further includes a frame grabber as signal capturing device (109) and master clock (110) for motion and image synchronization. The method for multiple-view panoramic imaging comprising capturing and generating multiple-view panoramic images using a single line-scan camera (107) wherein the camera (107) has 2 (two) distant centers (104, 105) of rotation enabling multiple-view rotation and panoramic rotation. Panoramic rotation is a rotation of the rotary stage (103) while the multiple-view rotation is a rotation by a capture plane (108).
Abstract:
The present invention relates to an apparatus and method for volumetric multi- modal hand biometric identification characterized in that wherein the present invention comprises of an illumination source for emitting near infra-red (0.75-1.4 µm in wavelength) and structured light, a camera system with a recorder adapted to capture an image of the object in a digital form; and data fusion that processes the data representation to produce useful information to the system managers and wherein palm prints are extracted from scanners which scanned the palm in which vein pattern biometrics records subcutaneous infra red absorption patterns to produce unique and private identification templates of a user.
Abstract:
A device and method for a surveillance system utilizing a wide view camera a serves as guiding system to determine the area of interest i.e. the area where the presence or absence of activities within the area that is being monitored, together with a high resolution camera which is controlled in pan, tilt and zoom which provides a zoomed image of the area of interest.
