  • Publication number: 20210407036
    Abstract: Disclosed is a method of identifying an object using at least one imaging. The method comprises acquiring calibration information for each of the imaging device arranged substantially perpendicular to a planar surface of the object, capturing an image of the planar surface using each of the imaging device, generating a transformed image corresponding to each image of the planar surface, using the calibration information of the imaging device used for capturing each image, generating a security map for each transformed image, wherein the security map comprises a weightage factor for each pixel of the transformed image, and wherein the weightage factor is based on image resolution of the transformed image, and constructing a resultant image of the planar surface using each transformed image and the security map for the transformed image, to identify the object.

  • Patent number: 10187589
    Abstract: A system and method for mixing a scene with a virtual scenario. An image capturing unit is arranged to capture at least one image so as to cover the scene from a first viewpoint. An image representation generation unit is arranged to generate at least one image representation based on the captured image. A game engine unit is arranged to generate a virtual scenario. An image processing unit is arranged to adapt the at least one image representation based on the generated virtual scenario so as to provide a virtual video sequence.

  • Patent number: 10127458
    Abstract: The present invention relates to a method for categorizing a moving object within a scene In particular, the present invention relates to a method specifically taking into account the three dimensional data within a scene for determining the location of and type of objects present within the scene. The method involves determining a first probability level for the type of object based on its size and shape, determining a second probability level for the type of object based on its relative speed, and defining the type of the object based on a combination of the first and the second probability level. The invention also relates to a corresponding system and a computer program product.

  • Patent number: 9476987
    Abstract: A method of estimating absolute orientation of a vehicle utilizing a camera and GPS. At least three images are selected from concurrent images taken above an essentially horizontal ground at a distance from each other. Key points are identified in each selected image. Absolute positions of the images are obtained from the GPS defining the image positions when a respective image was taken. Key points between selected images are matched to obtain an estimate of the absolute orientation.
