A Calibration-And-Error Correction Method For Improved Texel (Fused Ladar/Digital Camera) Images, Scott E. Budge

Electrical and Computer Engineering Faculty Publications

The fusion of imaging ladar information and digital imagery results in 2.5-D surfaces covered with texture information. Called "texel images," these datasets, when taken from dierent viewpoints, can be combined to create 3-D images of buildings, vehicles, or other objects. These 3-D images can then be further processed for automatic target recognition, or viewed in a 3-D viewer for tactical planning purposes. This paper presents a procedure for calibration, error correction, and fusing of ladar and digital camera information from a single hand-held sensor to create accurate texel images. A brief description of a prototype sensor is given, along with …
