DESIGN, FUNCTION, AND UTILISATION OF AN EQUIPMENT FOR CAPTURING OF THREE-DIMENSIONAL IMAGES

摘要

The invention considers construction and usage of three-dimensional image capture equipment. The invention is based on capturing of two images different perspective with a predefined displacement, which is dependent on a number of parameters. The construction is based on the lens located in a displaceable cradle/sledge. On each side of the cradle/sledge there is a so-called system of cushions. These systems of cushions can influence the displacement of the lens through filling and emptying of liquid/gas/any other substance. The captured object is captured by a camera, for example a CCD camera which in turn transmits the image as a video signal to a computer. The computer fuses the two images through image processing to one 3D image. The 3D image can later be seen by the help of HMDs (Head Mounted Displays), on a monitor or through 3D glasses. The invention can with benefit be used in applications where the size or diameter of the instrument is decisive for the result, for example in the medical field, endoscopy, i.e. arthroscopy, laparoscopy, cystoscopy aso. Additionally it is important for the surgeon to get a spatial perception of the field of the operation. It will then become easier to estimate distances, sizes etc.
