CoMet: Modeling Group Cohesion for Socially Compliant Robot Navigation in Crowded Scenes

نویسندگان

چکیده

We present CoMet, a novel approach for computing group’s cohesion and using that to improve robot’s navigation in crowded scenes. Our uses cohesion-metric builds on prior work social psychology. compute this metric by utilizing various visual features of pedestrians from an RGB-D camera on-board robot. Specifically, we detect characteristics corresponding the proximity between people, their relative walking speeds, group size, interactions members. use our design scheme accounts different levels while robot moves through crowd. evaluate precision recall pedestrian datasets. highlight performance algorithm Turtlebot demonstrate its benefits terms multiple metrics: freezing rate (57% decrease), deviation (35.7% path length trajectory(23.2% decrease).

Socially compliant mobile robot navigation via inverse reinforcement learning

Mobile robots are increasingly populating our human environments. To interact with humans in a socially compliant way, these robots need to understand and comply with mutually accepted rules. In this paper, we present a novel approach to model the cooperative navigation behavior of humans. We model their behavior in terms of a mixture distribution that captures both the discrete navigation deci...

Forecasting Social Navigation in Crowded Complex Scenes

When humans navigate a crowed space such as a university campus or the sidewalks of a busy street, they follow common sense rules based on social etiquette. In this paper, we argue that in order to enable the design of new algorithms that can take fully advantage of these rules to better solve tasks such as target tracking or trajectory forecasting, we need to have access to better data in the ...

Feature-Based Prediction of Trajectories for Socially Compliant Navigation

Mobile robots that operate in a shared environment with humans need the ability to predict the movements of people to better plan their navigation actions. In this paper, we present a novel approach to predict the movements of pedestrians. Our method reasons about entire trajectories that arise from interactions between people in navigation tasks. It applies a maximum entropy learning method ba...

Online multiple people tracking-by-detection in crowded scenes

Multiple people detection and tracking is a challenging task in real-world crowded scenes. In this paper, we have presented an online multiple people tracking-by-detection approach with a single camera. We have detected objects with deformable part models and a visual background extractor. In the tracking phase we have used a combination of support vector machine (SVM) person-specific classifie...

Role Playing Learning for Socially Concomitant Mobile Robot Navigation

In this paper, we present the Role Playing Learning (RPL) scheme for a mobile robot to navigate socially with its human companion in populated environments. Neural networks (NN) are constructed to parameterize a stochastic policy that directly maps sensory data collected by the robot to its velocity outputs, while respecting a set of social norms. An efficient simulative learning environment is...
