8MOUT Training Situation
- The shortcomings
- Before Lack of exploratory training
opportunities for larger units and their
familiarization with a complex spectrum of
training events to be encountered in Mojave Viper
(training before the courses in physical training
facilities) mission planning and mission
rehearsal. - During Lack of optimal support for human
operation and supervision of training in physical
facility help resolve ambiguities, accurately
capture-measure-analyze-detect-record-bookmark--v
isualize instances of all important events and
performances of the warfighters. - After Lack of intelligent after-action review
with behavior analysis and smart inquiries about
units performances. Lack of opportunities for
remediation and exploration of alternative
courses of action (free-play). Lack of system
support for analysis of historical data to
indicate a need for possible doctrinal and
instructional changes.
9Our Approaches
- Affect large number of participants (ideally
everyone) incorporate elements that ensure
easier and faster large scale adoption of this
technology innovation. - Provide solutions that empower both instructors
and trainees. - Affect largest portion of units training cycle
solution should address their training needs
before the exercise, operational needs during the
exercise, and operational and training needs
after the exercise. - Provide a complete package solution technology
(systems, tools, algorithms) and training
methodologies of how to use that technology most
effectively. - Affect different layers of their organization
structure - ensure the paths for
organization-wide benefits and provide useful
understandings for Marine-wide organization.
10Our Approaches (2)
- Solutions transparent to participants when their
safety is of concern no changes of the way they
conduct training, no interference with training
event, - Offered solutions constitute supplementary
training interventions, - Solutions applicable to a variety of military
training situations segments applicable to
non-military situations, - Use Open Source software solutions Delta3D,
MySQL - No proprietary solutions, no license issues -
open the paths for easy future upgrades (by
anyone and whenever needed).

16Need for ST
- Provide effective behavior analysis and behavior
synthesis from the set of accurate 3D data
acquired during units performance in real
training environment. - Design a multi-sensor data capture system capable
of recording and deriving dynamic 3D participant
models, and dynamic multi-dimensional participant
pose tracks that can be viewed from any
perspective. - Design automatic semantic parsing and analysis of
the dynamic models and tracks, and identify
individual and team performance trends. - Design approaches and system that provides
re-play, intelligent inquiries and free-play
(alternative courses of actions) features, to
serve USMC training needs before and after
training in physical MOUT environment. - Design novel training approaches to be used with
the system - maximize training potential for the
masses of intended users.
17Technical Objective
- Provide a state-of-the-art, multipurpose system
and set of training approaches to support a wide
range of training and operational needs in
preparing for and conducting training in MOUT
facilities, and remediation of training after the
courses in physical environments. - Provide a system that represents a synergy of
computer vision, computer graphics (including
virtual reality), cognitive science and
artificial intelligence technologies at the level
that has not been attempted before in military
domain, and not done with the scale and
complexity that is planned in this project. - Roll up the training-planning-rehearsal-executio
n-review cycle such that it is viewed as one
(albeit phased) event rather than five.
18Multi-sensor Solution
- Different types of sensors
- Optical sensors (multiple PTZ cameras) 3D real
time data acquisition 2D images/video -gt 3D
Marine position Marine pose - Position sensors - GPS (IGRES) 3D Marine
position - Inertial sensors head and weapon orientation
- Size of training environment 1 x 1 km
193D Marine Position
- Capabilities Provide as accurate as possible 3D
information about each Marine inside the training
environment. - Concept Derive best 3D position using 3D
real-time vision based data acquisition and
associated 2D video techniques. - Automated PTZ movement, Video-GPS track fusion
and hand-off to keep Marine targets in view, - Improve position estimation accuracy from 2-6m
offered by GPS alone to sub-meter for behavior
analysis, - Improve accuracy by fusing GPS and video based
position estimation using video registration to
3D scene model and reference imagery, - For training video, Marines position will be
estimated using a human model to account for
height of the Marine and the change of the
perspectives w.r.t. the gimbaled camera.
20Marine Pose Estimation
- Capabilities New methods for estimating
participant pose and shape parameters, including
the dynamic parameters of an articulated 3D human
body model, and 3D models of their dynamic shape
and appearance. Dynamic articulated body posture
will enable new automated behavioral analysis
(squatting, kneeling, prone, etc.). Different
degrees of Marine-specific appearance and shape
information will offer new visualization
capabilities. - Concept Multi-scale/resolution model-based 3D
participant model reconstruction for vision-based
participant tracking and modeling related to
exercise capture and control.

21Behavior Analysis
- Capabilities Automatically detect and recognize
Marine behavior in a training exercise and
evaluate Marines performance. - Concept Combine position, poses and motion
based time series and classify them develop
Marine training ontology. - Human tracking data cannot be usefully
partitioned at predefined training events -
unambiguous well defined events occur rarely
(each unit has different plan of attack). - More interesting behaviors require correlating
longer periods to find trends over time. - AAR greatly benefits from knowing when such
higher-level behaviors occur. - Establishing such behaviors benefits from
tracking of consistency of acceleration and
velocity vectors, as well as line-of-sight
analysis on the terrain, and correlation between
the fire and movement (maneuver). - Solutions to be validated by the SMEs.
22Behavior Synthesis Free Play
- Capabilities Ability of Marine to directly
control actions of all entities of interest. Go
beyond passive playback system and review of past
training events - allow Marines to jump into
free-play mode and explore alternative ?courses
of action not represented in the exercise
database. - Concept AI control of all other entities
responsive to and consistent with the Marine's
control ?actions. - Behavioral models based on naturalistic decision
making theory (mental simulation), - High fidelity, image based perceptual models
(detections, missed detections, false positive
?detections), - Environment understanding based on automated
environment exploration. - Solutions validated by the SMEs
23Advanced Display Platforms
- Capabilities Display platforms for individual
and group use before, during, and after
exercises. - Concept Technologies and methods for deployable
wide-area display systems based on ad hoc
collections of new intelligent projection units
(IPU) that automatically continuously correct
for image distortions, photometric blending, and
mechanical perturbations. Develop IPU-based
approaches to dynamic projection on non-planar
surfaces for real-virtual sand tables. Develop
pose-aware handheld display devices for
situational awareness in situ during an exercise. - Conventional projector-based systems typically
support one-shot image-based calibration. IPUs
will combine projection engines, image and other
sensors, and new algorithms for continuous and
automatic geometric and photometric calibration.

253D Visualization System
- Capabilities
- Provide augmented situational awareness and
analysis of units past performance. Enable not
only easier operation of physical training
facility but also training before and after the
training in that environment mission planning,
mission rehearsal, behavior (performance)
analysis and free-play. - New behavior analysis with smart queries of unit
(past) performance in physical environment
(including playback feature) and exploration of
alternative courses of action. Use open source
software solutions and enable future easy(er)
upgrades. - Concept Integration of the results of computer
vision, computer graphics (VR), cognitive science
and AI in a single 3D visualization system.
26Learning Training Methodologies
- Capabilities A novel set of learning and
training methodologies to maximize training
results in preparation for training in physical
MOUT facility (mission planning and mission
rehearsal). - Concept (1) Explore a combination of new and old
(traditional) instructional approaches and
systems, (2) Inject motivation tools and aspects
in instructional design, (3) Incorporate
parameters that support fast, large scale
adoption of our solutions how to train the
trainers.
