Extracting 3-dimensional information from single camera vision system
In this paper, a new approach for extracting three-dimensional information from single camera vision system is presented. Only one plan view of the object will be obtained from a camera when the object is placed in the air, even if the threshold of the camera is varied. The result will be however significantly different when the object is located in a colour liquid. It is due to high absorption of the light in a colour liquid. The amount of absorption varies with the depth of the liquid. This allows different plan views related to the depth of an object to be produced by changing the threshold level of the camera. The different layers of the plan view can be combined to generate a 3-D map of the object. The vertical cross-section of the object at any point can be then obtained by processing this 3-D information.
