Abstract: Systems and methods for automatically generating a 3D model of a roof of a building are provided. In a described embodiment, the method includes receiving point cloud data comprising a plurality of data points corresponding to height measurements at a given location; processing the point cloud data to identify roof surfaces; generating a 3D model of the roof using the identified surfaces; receiving aerial imagery of the roof; registering the aerial imagery with the point cloud data; and refining the 3D model using the aerial imagery. A corresponding computing system and non-transitory computer readable medium for carrying out the methods are also provided.

Abstract: The present invention provides a system and a method for graphically enhancing the visibility of an object/person on a video image used in broadcasting a sport event. For broadcasting the sport event, one or a plurality of video camera acquire video images of the event. The object/person of which the trajectory is of relative importance in the sport game is generally in the field of view of the video camera but may or may not be visible on the images. When the object/person travels, a monitoring module passively tracks the object/person and measures the 3D position of the object/person. As the event is being broadcast, a graphical representation of the object or of its trajectory is depicted on the image to enhance the visibility of the object/person on the broadcast image.
