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.
Abstract:
The present invention relates to a surveillance system having a method for tampering detection and correction. The surveillance system is able to detect tampering of the camera view and thereon, adjust its video analytics configuration parameters to perform video analytics even though the orientation of the camera (10) has been changed as long as a partial of the ROI is within the tampered camera view. The surveillance system comprises of at least one camera (10), a video acquisition module (20), a storage device (30), an image processing module (40), a display module (50) and a post detection module (60).
Abstract:
The present invention discloses a system and method for object tracking and image projection which may be used for a surveillance system or for providing information to users by way of a display adjacent to users within the monitored area. The system comprises a video camera (200), a light projector (208), housing for the light projector (210), a plurality of motors (202, 204, 206) for providing movements to the light projector (208), a support pole (216), and a mirror (212) for enabling the light projector (208) to illuminate or project images at the targeted object for tracking by way of reflecting therefore diverting the illumination from the light projector (208). There is further provided a control and processing system (300) connected to the projector (208) and the camera (200) for providing overall system control and further processing of the captured images by the camera (200). The system of the present invention provides continuous tracking of an object within the monitored area upon suitably prompted by the control and processing system (300).
