    Patent number: 6404427
    Abstract: A rapid checking method for determining whether an object is located within a field of vision is provided. A computer serves to process the states of a 3D image so as to determine whether the object is located within the field of vision. An efficient calculation process is used. In the invention, the 3D coordinates of eight vertexes of an object and the boundary box formed by equations of six planes are employed in operation. By determining the relationship of the vertexes and the planes, it is determined whether an object is within the field of vision.
