摘要： An image processing apparatus and method generate a three dimensional representation of a scene which includes a plurality of objects disposed on a plane. The three dimensional representation is generated from one or more video images of the scene, which include the objects on the plane produced from a view of the scene by a video camera. The method comprises processing the captured video images so as to extract one or more image features from each object, comparing the one or more image features with sample image features from a predetermined set of possible example objects which the video images may contain, and identifying the objects from the comparison of the image features with the stored image features of the possible example objects. The method also includes generating object path data, which includes object identification data for each object which identifies the respective object; and provides a position of the object on the plane in the video images with respect to time. The method further includes calculating a projection matrix for projecting the position of each of the objects according to the object path data from the plane into a three dimensional model of the plane. As such a three dimensional representation of the scene which includes a synthesised representation of each of the plurality of objects on the plane can be produced, by projecting the position of the objects according to the object path data into the plane of the three dimensional model of the scene using the projection matrix and a predetermined assumption of the height of each of the objects. Accordingly, a three dimensional representation of a live video image of, for example, a football match can be generated, or tracking information included on the live video images. As such, a change in a relative view of the generated three dimensional representation can be made, so that a view can be provided in the three dimensional representation of the scene from a view point at which no camera is actually present to capture video images of the live scene.

摘要： Method and system for determining whether a spherical element impacts with a component of a playing field, or arranged on or proximate thereto The method comprises: a) acquiring images of a surveillance area of a field that covers at least part of said component, such as a delimiting perimeter line (L) of a game area (Z1-Z10) or a target (A1-A8); b) performing an approximate detection of an impact of a spherical element relative to that component or proximate thereto, with an object detection and recognition system that can discern when the detected object is indeed a spherical element; c) automatically selecting one of the images acquired for the same point in time and that includes the area where said impact has occurred; and d) analysing the selected image to check if the spherical element has impacted or not with the component. The system is adapted to implement the method of the invention.

摘要： The invention concerns a device and an automatic resetting method using electronic means intended for a geometric model of a scene over a picture of the scene including fixed references, the electronic means comparing the picture with model having been adjusted in perspective by homography for superimposition of the references. According to the invention, the electronic device calculates a fine homography function Hf for resetting into three phases: a first preliminary phase of determination of an average resetting homography consisting in determining an average homography function Hm applicable to the model with average adjustment over a sample of pictures of the scene taken previously, a second, rough resetting phase consisting after application of the average homography function Hm, to the model in determining a rough homography function Hg, and a third, fine resetting phase consisting after application of the rough homography function Hg to the model in determining the fine homography function Hf.

摘要： 1. Process for calibrating a video and TV camera (10), based on a view where a circle (1) and at least one line are visible, it comprises the followinf stages: calculation of a homography that transforms the circle unit into the circle (2) projected onto the image; full determination of the homography that transforms the reference plane (3) in the scene in the plane projected (4) on the camera (10) based on two additional geometric elements; and calculation based on the homography of the focal length (f) and of the position and orientation of the camera (10) in space. Said two additional geometric elements can be the point of the centre (7) of the circle (1) and the line (5) that crosses the centre (7) of the circle (1) or alternately two straight lines (5, 5') visible in the image.

摘要： A method for encoding a video stream generated from at least one ultra-high resolution camera capturing sequential image frames from a fixed viewpoint of a scene includes decomposing the sequential image frames into quasi-static background and dynamic image features; distinguishing between different objects represented by the dynamic image features by recognizing characteristics and tracking movement of the objects in the sequential image frames. The dynamic image features are formatted into a sequence of miniaturized image frames that reduces at least one of: inter-frame movement of the objects; and high spatial frequency data. The sequence is compressed into a dynamic data layer and the quasi-static background into a quasi-static data layer. The dynamic data layer and the quasi-static data layer are encoded with setting metadata pertaining to the scene and the at least one ultra-high resolution camera, and corresponding consolidated formatting metadata pertaining to the decomposing and formatting procedures.

摘要： The invention relates to a method for determining the geometric parameters indicating the movement of a camera, which involves: recording a set of P video images of an action carried out over at least one segment of a surface having a texture, wherein each image p is, each time, at least partially segmented into a number N of areas; selecting, for each of the images of said set, a subset of M (M ≤ N) of said areas, each of the M areas having an image element continuing said texture; each time, forming a pair of the images p-i and p so as to then create a series of S (1 ≤ s ≤ S) geometric projections of said selected M areas and determine a rate of coincidence between the projected areas; and searching, from among the S geometric projections, for the geometric projection that provides the highest rate of coincidence between the areas of the images p-i and p.
