Automation of construction processes can result in reduced project costs and increased worker safety. A process that lends itself to automation is the picking and placing of objects. However, determining the pose (position and orientation) of an object is critical. LADAR (laser detection and ranging) data provides 3D information of a scene, but the data are noisy, contain outliers, and have phantom points along edges of objects. A preliminary algorithm to preprocess the data and to compute the object pose is presented. The algorithm was validated through comparison with experimental measurements.
