Abstract :
Proposes a method for obtaining precise range information by swiveling a conventional TV camera. In the proposed method the authors make use of the blurring that occurs in the image resulting from aberrations of the TV camera lens. The direction to the object can be measured with a subpixel-level precision which depends on the angular resolution of the camera controller. The uncertainties of the object locations measured by conventional stereo methods depend on the resolution of the image sensor. However, the method can locate objects with a precision depending on the angular resolution of the camera controller, which is 10 to 20 times better than the conventional image method
