Precise matching of 3-D target models to multisensor data
This paper presents a three-dimensional (3-D) model-based ATR algorithm that operates simultaneously on imagery from three heterogeneous, approximately boresight aligned sensors. An iterative search matches models to range and optical imagery by repeatedly predicting detectable features, measuring support for these features in the imagery, and adjusting the transformations relating the target t...
متن کاملMultiple Target Tracking With a 2-D Radar Using the JPDAF Algorithm and Combined Motion Model
Multiple target tracking (MTT) is taken into account as one of the most important topics in tracking targets with radars. In this paper, the MTT problem is used for estimating the position of multiple targets when a 2-D radar is employed to gather measurements. To do so, the Joint Probabilistic Data Association Filter (JPDAF) approach is applied to tracking the position of multiple targets. To ...
متن کاملCortical Dynamics of 3-d Figure-ground Perception of 2-d Pictures
This article develops the FACADE theory of :3-D vision and figure-ground separation to explain data concerning how 2-D pictures give ri;;e to 3-D percepts of occluding and occluded objects. These percept;; include pop-out of occluding figures and amodal completion of occluded figures in response to line drawings, to Bregman-Kanizsa displays in which the relative contrasts of occluding and occlu...
متن کاملComparing Effects of 2-D and 3-D Visual Cues During Aurally Aided Target Acquisition
The aim of the present study was to investigate interactions between vision and audition during a visual target acquisition task performed in a virtual environment. In two experiments, participants were required to perform an acquisition task guided by auditory and/or visual cues. In both experiments the auditory cues were constructed using virtual 3-D sound techniques based on nonindividualize...
متن کاملPrecise 3-D Localization by Automatic Laser Theodolite and Odometer for Civil-engineering Machines
This paper presents a navigation system providing precise 3-D position and spatial attitude data for slow outdoor vehicles. Our system uses an odometer and an automatic laser theodolite, the data of which are fused using a Kalman filter. We show through different experiments carried out with the evaluation station Sessyl that the high accuracies required for some civil-engineering tasks are ful...
