Abstract
There is provided a three-dimensional imaging system (2), including a first camera (6) and a second camera (8), both facing a field of view of two-dimensional images and a normally open, fast gating device (12) interposed between the second camera (8) and the field of view (14 and 26). The system further includes a frame grabber (10) connected to the first and the second camera, and a computer (14) for receiving signals representing, pixel by pixel, light intensities of an image during a predetermined period of time and signals representing same pixel by pixel of light intensities arriving at the second camera until the fast gating device (12) is closed, and for determining three-dimensional imaging signals therefrom to eventually be displayed. A method for producing three-dimensional imaging is also provided.
