Analysis and Removal of artifacts in 3-D LADAR Data J. Tuley Nicolas Vandapel Martial Hebert 10.1184/R1/6551942.v1 https://kilthub.cmu.edu/articles/journal_contribution/Analysis_and_Removal_of_artifacts_in_3-D_LADAR_Data/6551942 Mixed pixels are points in LADAR data which occur when the measurement beam intersects two objects at within a certain range of distances apart. The resulting return signal represents data from both objects; the laser electronics read this as a single point, but not at the real location of either object. As such, mixed pixels present an obstacle to accurate analysis of a scene. We present a survey of mixed pixel phenomena and a method of removing mixed pixels from scenes stored as 3-D points. Our method does not depend on the sensor used to originally collect the data, and is efficient and effective. 2004-01-01 00:00:00 Robotics
