BESTIMMUNG DER POSITION UND DER BEWEGUNG EINER STUDIOKAMERA UNTER BENUTZUNG DER KAMERABILDER |
摘要 |
Studio camera position and motion may be derived from the camera image by separating out the background and deriving from a background having a number of areas of hue and/or brightness different from adjacent areas estimates of movement from one image to the next. The initial image is used as a reference and amended with predicted motion value. The amended image is compared with incoming images and the result used to derive translation and scale change information. Once the proportion of the reference image contained in an incoming image falls below a threshold a fresh reference image is adopted. <IMAGE> |
