A method of processing image data entails the input of user selected image co-ordinates using a display interface in which a mouse is used to control the position of a cursor. A magnified image is additionally displayed in a magnified image window which overlays a corner portion of the main image window. The magnified image includes a fixed graticule and displays a magnified portion of the image which tracks the current position of the cursor, thereby enabling the user to locate the cursor with greater accuracy with reference to the magnified image. After selection of an image point, the image displayed in the magnified window is frozen. Matching image point co-ordinates in two separate images may be input to the processor by providing respective magnified image windows in each of the main image windows. The magnified images thereby provided enable pairs of matching co-ordinates to be rapidly selected without the need for the user to input any additional instructions to control the generation of the magnified images. The method is particularly useful in providing matching image co-ordinates for generating a three-dimensional model based on a series of image frames representative of different views of the object. A further aspect of the invention provides for a pair of camera images to be automatically selected in response to the user selecting a set of primitives in the model image. |
