METHOD OF DISPLAYING DIGITAL IMAGE FOR DIGITAL LOCATING SYSTEM AND DEVICE FOR UNDERGROUND OBJECT DETECTION
First Claim
1. A method of displaying a digital image of an underground object emitting a flux field on a display screen of a locating receiver, comprising the steps of:
- providing two measurement points in space around said underground object, each measurement point being connected to said object by a first vector and a second vector;
measuring a degree of misalignment of the first vector and the second vector by assigning a numerical value to said first vector and said second vector and calculating a third vector, said third vector being a cross product of said first and second vectors;
calculating vector gain;
using said cross-product to determine the direction from which the flux field originates;
whereby the components of said third vector are used to produce a digital image of said underground object on the display screen of said receiver.

Abstract
An underground digital locating system includes a receiver capable of acquiring a signal produced by an underground object and displaying a digital representation of the orientation of underground object and of its depth. The system includes a carrying case for the digital locating receiver, the carrying case further including a transmitter for energizing underground objects to emit a magnetic field. A method of locating an underground object using the described system is also disclosed, as well as methods of measuring a flux field and translating a flux field signal of an underground object into a visual representation of the underground object on the display screen of the locating receiver.
