3. the tracking of mark
After marker is confirmed, can confirm to follow the trail of with four angle points, obtain world coordinate system and sign coordinate system and camera coordinate system and sign coordinate system.When directly from image, obtaining the failure of square mark; System will get into the tracking mode of mark; MXRToolkit realizes the tracking to mark through the corners Matching of image; This algorithm obtains the initial position of angle point through the corresponding homography matrix of previous frame image, and search arest neighbors angle point upgrades current corner location in present image; And then reject the point of matching error through the method for RANSAC list of references [2] " a paradigm for model fitting with applications to image analysis and automated cartography. ", obtain new homography matrix.
The image generation module is put into dummy object in the three-dimensional system of coordinate at mark place through transition matrix according to the three-dimensional coordinate of the mark of image locating module calculating.As shown in Figure 5, according to the three-dimensional coordinate of mark, with virtual objects--teapot is placed into the coordinate position of mark.Select the recreation render engine of torque3D in the present embodiment, be placed into virtual object among the real image.Because dummy object has static and dynamic; So in real world, can have an X-rayed, dummy object is controlled in rotation; And embody the alternant way of the image of all angles through nature, this all is the function that present torque3D recreation render engine can be realized fully.Add that particle, effect such as audio-visual can let the user stay deep impression.
