54. A method for warning the operator of a stationary or moving vehicle of potential collisions with objects in his physical environment, where the environment may include obscuration, comprising the steps of:
-
generating a series of pulses of light;
transmitting said light into said environment;
collecting light from said environment during the time of transmission and reflection of said light from said objects;
providing electrical signals from a plurality of positions on the objects with a single light pulse, storing said electrical signals on a plurality of unit cells corresponding to the said plurality of positions on said objects, providing signals from said storage means, converting the signals stored on said storage means to three dimensional images of the objects;
processing said images to calculate the likelihood of object collisions with said vehicle;
communicating the results of said calculation to the vehicle operator - View Dependent Claims (55, 56, 57, 58, 59)
