Abstract
The three-dimensional (3D) location of objects can be determined using triangulation techniques with two or more passive, angles-only optical sensors. The present work describes how to determine necessary experimental parameters, such as camera resolution, pointing and location knowledge, and target pixel position estimation accuracy, in order to achieve a required 3D position accuracy. Two general types of accuracy requirements are examined, one in which absolute position of the object relative to an external coordinate system is required, and the second in which relative position of one object relative to a second object is required. While the basic approach can be applied to a wide variety of geometries and sensor-to-target ranges, the emphasis of this work is on outdoor applications involving long sensor-to-sensor baselines.
